Those bugs that are common in fall, winter and spring are 2 Viruses =  The Cold & The Flu.

HOW THEY ARE DIFFERENT:

Both influenza and the common cold are viral respiratory infections (they affect the nose, throat, and lungs). Viruses are spread from person to person through airborne droplets (aerosols) that are sneezed out or coughed up by an infected person, direct contact is another form of spread with infected nasal secretions, or fomites (contaminated objects).  Which of these routes is of primary importance has not been determined, however hand to hand and hand to surface to hand to contact seems of more importance than transmission.  The viruses may survive for prolonged periods in the environment (over 18 hours for rhinoviruses in particular=a common virus for colds) and can be picked up by people’s hands and subsequently carried to their eyes or nose where infection occurs. In some cases, the viruses can be spread when a person touches an infected surface (e.g., doorknobs, countertops, telephones) and then touches his or her nose, mouth, or eyes. As such, these illnesses are most easily spread in crowded conditions such as schools.

The traditional folk theory that you can catch a cold in prolonged exposure to cold weather such as rain or winter settings is how the illness got its name.  Some of the viruses that cause common colds are seasonal, occurring more frequently during cold or wet weather.  The reason for the seasonality has not yet been fully determined.  This may occur due to cold induced changes in the respiratory system, decreased immune response, and low humidity increasing viral transmission rates, perhaps due to dry air allowing small viral droplets to disperse farther, and stay in the air longer.  It may be due to social factors, such as people spending more time indoors, as opposed to outdoors, exposing him or her “self” to an infected person, and specifically children at school.  There is some controversy over the role of body cooling as a risk factor for the common cold; the majority of the  evidence does suggest a result in greater susceptibility to infection.

The SIMPLE COMMON COLD:

The common cold (also known as nasopharyngitis, rhinopharyngitis, acute coryza, head cold) or simply a cold is a viral infection of the upper respiratory tract which primarily effects the nose.  There are over 200 different known cold viruses, but most colds (30% up to 80%) are caused by rhinovirusesThis means you can pass the cold to others, so stay home and get some much-needed rest for yourself and not passing it on to others for the contagious period at least.

If cold symptoms do not seem to be improving after a week, you may have a bacterial infection, which means you may need antibiotics, which only kill bacterial infections not viral.

Sometimes you may mistake cold symptoms for allergic rhinitis (hay fever) or a sinus infection (bacterial). If cold symptoms begin quickly and are improving after a week, then it is usually a cold, not allergy. If your cold symptoms do not seem to be getting better after a week, check with your doctor to see if you have developed an allergy or inflammation or the sinuses (sinusitis).

Influenza is commonly referred to as “the flu”, this is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses.  The most common sign or symptom are chills, fever, runny nose, coughing, aches and weakness to headache and sore throat.  Although it is often confused with other influenza-like illnesses, especially the COMMON COLD, influenza is a more severe illness or disease caused by a different virus.  Influenza nausea and vomiting, particularly in children but these symptoms are more common in the unrelated gastroenteritis, which is sometimes inaccurately referred to as “stomach flu” or “25 hour flu”.
The flu can occasionally lead to pneumonia, either direct viral pneumonia or secondary bacterial pneumonia, even for persons who are usually very healthy.  In particular it is a warning sign if a child or presumably an adult seems to be getting better and then relapses with a high fever as this relapse may be bacterial pneumonia.  Another warning sign is if the person starts to have trouble breathing.

Each year, 10% to 20% of Canadians are stricken with influenza. Although most people recover fully, depending on the severity of the flu season, it can result in an average of 20,000 hospitalizations and approximately 4000 to 8000 deaths annually in Canada. Deaths due to the flu are found mostly among high-risk populations, such as those with other medical conditions (such as diabetes or cancer) or weakened immune systems, seniors, or very young children. There are 3 types of influenza viruses: A, B, and C. Type A influenza causes the most serious problems in humans and can be carried by humans or animals (wild birds are commonly the host carriers). It is more common for humans seem to carry the most with ailments with type A influenza.  Type B  Influenza is found in humans also.  Type B flu may cause less severe reaction than A type flu virus but for the few for the many can still be at times extremely harmed.  Influenza B viruses are not classified by subtype and do not cause pandemics at this time.  Influenza type C also found in people but milder than type A or B.  People don’t become very ill from this Type C Influenza and do not cause pandemics.

The common cold eventually fizzles, but the flu may be deadly. Some 200,000 people in the U.S. are hospitalized and 36,000 die each year from flu complications — and that pales in comparison to the flu pandemic of 1918 that claimed between 20 and 100 million lives. The best defense against it:   a vaccine once a year, especially those living or working in high risk areas that put you in a high potential of getting the flu (Ex. poor area of living or working in the hospital).

Lets learn more tomorrow on signs and symptoms of COLDS versus THE TYPES OF FLUs (type A, B, C), and what to do if the symptoms are present.  See you Wednesday.

“There is only one basic human right, the right to do as you damn well please. And with it comes the only basic human duty, the duty to take the consequences.”

 
P. J. O’Rourke  (American political satirist and author)

Heart disease, cancer, stroke, chronic lower respiratory diseases, Alzheimer’s disease and diabetes continue to be leading causes of death among older adults, based on the Center for Disease Control & Prevention (saving lives and protecting people…CDC).  They also provide the following:

 Baby Boomers for the next 25 years equating to over 70 million people can live longer lives with them combining to double the population of older Americans in the next quarter of a century.  Baby Boomers can take steps to live long and healthy lives as opposed to a lot of their parents who died much younger.   Living healthier will play a positive impact on the health care system.  Starting a step towards prevention or treatment (Rx) of a present disease that you can improve is a mission we Americans owe to ourselves, our young ones, and to our nation’s future.

Through healthy dieting and behaviors (Ex. activity, nutrition, staying in your therapeutic body mass index, controlling stress both physically and mentally, oral health and dealing with any disability reaching the optimal health level you can reach) you can reach a healthier way to living.  If the majority of our nation lives healthier, shows progress in promoting prevention, improving the health and well-being of older adults with reducing behaviors that contribute to premature death and disability will increase a healthier population in the U.S.

Baby boomers should do the following with diet and exercise:

Get Screened

Get screened including flu vaccine, pneumonia vaccine, colorectal cancer screening, and mammography for women.

Mammography is the best available method to detect breast cancer in its earliest, most treatable stage before it is big enough to feel or cause symptoms. Women aged 50 and over should get mammograms every two years.

Colorectal cancer screening tests can find precancerous polyps so that they can be removed before they turn into cancer. They can also detect colorectal cancer early, when treatment works best. Older adults should be screened for colorectal cancer by having a fecal occult blood test during the past year or a colonoscopy within 10 years.

Get Vaccinated

Flu and pneumonia is the seventh leading cause of death among adults 65 years or older, despite the availability of effective vaccines. Older adults should get the flu vaccine every year and get the pneumonia vaccine at least once.

Be Physically Active

Regular physical activity is one of the most important things older adults can do for their health. Physical activity can prevent many of the health problems that may come with age, including the risk of falls.

How Much Activity Do Older Adults Need?

2 hours and 30 minutes (150 minutes) of moderate-intensity aerobic activity (i.e., brisk walking) every week and muscle-strengthening activities for 2 or more days a week that work all major muscle groups.

OR

1 hour and 15 minutes (75 minutes) of vigorous-intensity aerobic activity (i.e., jogging or running) every week and muscle-strengthening activities on 2 or more days a week that work all major muscle groups.

OR

An equivalent mix of moderate and vigorous-intensity aerobic activity and muscle strengthening activities on 2 or more days a week that work all major muscle groups.

Eat Fruits and Vegetables Daily

Diets rich in fruits and vegetables may reduce the risk of some cancers and chronic diseases, such as diabetes and cardiovascular disease.

Quit Smoking

Tobacco use remains the single largest preventable cause of disease, disability, and death in the United States. For help visit www.smokefree.gov.

Take Medication for High Blood Pressure and Diabetes

High blood pressure & Diabetes is a major risk factor for cardiovascular disease, it’s one of the leading causes of illness and death among older adults. More than ½ of Americans don’t have their blood pressure under control.  Complianceis so essential in treating HTN, Diabetes or any disease including what your M.D. feels you need as a medication, if needed.  The only way to find out is by seeing your health care providers, such as doctors, nurses, and pharmacists, who can track their patient’s blood pressure, prescribe once-a-day medications, and give clear instructions on how to take blood pressure & diabetic medications.

Patients should take the initiative or responsibility to monitor their blood pressure and sugar levels (finger sticks) between medical visits and know what abnormal values to report to their MD.  Including taking their medications as prescribed, tell their doctor about any side effects, and make lifestyle changes, such as eating a low-sodium/low-calorie diet, exercising, and stopping smoking.

For so many years America has been warned about being overweight/unhealthy but still today the majority of Americans (all age groups) are obese, up to 2/3 of our country.  To the point it affects society in the U.S. that even our politicians have to ban certain drinks or foods to the public since many can’t take the better choice on their own for the healthier moves which is taking foods/drinks that are high in sugar or fat or calories in moderation or even occasionally.  Instead our society goes the less healthier direction that causes many cardiac (blockages in the vessels), endocrine (Diabetes II) with many other diseases as a ending result, in time.  No matter if you are in a high or low income bracket there are affordable foods that you can have in your diet with gradually increasing to 30 minutes of exercise daily or every other day in your life, of course in time.  It’s just like watching TV,  you just have to fit it in your life and in time it will become a regular part of your activities of daily living with not making you feel as if this is a burden but routine.  If you want to live a longer life, help decrease disease in our country then make a move whether young, mid-age or even older.  It is like a wound that our society over generations allowed to happen, in time.  The ending result is 2/3 of our country is obese,  do we want to continue making this wound larger.  We already have caused a large number of obesity but like all wounds, time heals all wounds (if not completely than to a degree and in America the case is a large one).  We are now in a technology that knows what foods high in fat, high in sugar, high in carbohydrates, high in calories on a daily basis in all yours meals can cause which is obesity as the ending result.   We are a stronger nation in all colors, races, ages, and sexes with knowing the knowledge of what to do.   Do you want a better fit body or even an overall healthier family including grandchildren and even our country than take the action NOW.  For your goal in playing a part in living healthier and spreading the good news.  Also, for the next decade & generation to be healthier will help Americans holistically in their lives all around (including our health care showing a spread of disease in lower percentage due to healthier dieting and activity choices by our people, who are so important in helping to decide where the health of the present and future of the US citizens lie.  Should it take our government to make a move (finally after so many years)?  I know I wouldn’t want them making the last move in our society and if you want to take part in joining me (at almost 50 y/o) than go to healthyusa.tsfl.com and be a part of making our home a healthy USA.   

“Several factors could explain the positive association between time spent sitting and higher all-cause death rates,”. “Prolonged time spent sitting, independent of physical activity, has been shown to have important metabolic consequences, and may influence things like triglycerides, high density lipoprotein, cholesterol, fasting plasma glucose, resting blood pressure, and leptin, which are biomarkers of obesity and cardiovascular and other chronic diseases.” 

Alpa Patel, Ph.D (The doctor who was one of the researchers who led the exploration to the association between sitting time and mortality analyzed survey in the American Cancer Society’s Cancer Prevention II study in 1992.

 LOOKING AT ACTUAL STUDIES SUPPORTING THE OBESITY&CANCER LINK

Take for example through the American Cancer Society they stated in an article 2006 that a substantial evidence from clinical trials has established that obesity significantly increases the risk for heart disease and diabetes.  More recently, suspicions that obesity is linked to prostate cancer have been supported by a number of investigations, but the relationship has remained unclear.  Now through a pair of new studies provides scientists with some important insights that may have an impact on how physicians manage their patients with prostate cancer.

The pair of studies show 2 significant studies relating how obesity links with prostate cancer, which were:

The implication is that prostate cancer patients who are obese should probably be followed more closely than patients with similar cancer characteristics who are not obese. That could include regular digital rectal exams, more frequent prostate-specific antigen (PSA) testing, and perhaps setting a lower PSA cutoff point as an indication of recurrence, Kane explained.

The greater risk associated with obesity may be related to technical issues, Kane said. For example, it’s more difficult for surgeons to perform a radical prostatectomy in obese patients. However, surgical challenges offer only a partial explanation. In studies where surgeons verified that they had removed all cancer cells during radical prostatectomy, obese patients were still more likely to experience a recurrence of the disease.

The second study, a multi-center trial coordinated at the Duke University School of Medicine in Durham, NC, found that obese men under the age of 63 tend to have larger prostates, which makes finding tumors more difficult. As a result, there’s a real danger of delayed diagnosis, which decreases the chances of a cure and puts patients at greater risk for dying of the disease. The findings appear in the Journal of Urology.

“It’s harder to find cancer in larger prostate glands,” explained Stephen J. Freedland, MD, assistant professor of urology and member of the Duke Prostate Center at the Duke University School of Medicine. “Consequently, our data suggest that we may be underdiagnosing cancers in younger obese men. That also means that the tumors we do pick up are likely to be at a more advanced stage and perhaps more aggressive, and therefore more difficult to treat.”

Let’s look at this at a broader aspect, not just pertaining to prostate cancer.  This would be, “It’s not just patients with prostate cancer that studies like this should be directed toward,” Dr. Kane said. “Patients who are clearly at risk for developing the disease should also take notice of our findings. The central message is yet again that obesity has been identified as an important risk factor for a potentially deadly disease. For all of us, controlling our weight through diet and exercise is important, and we shouldn’t have blinders on and just think of prostate cancer. The number one risk of death for American men is heart disease, so anything we can do to reduce that risk that also reduces the risk for prostate cancer is useful.”  Including it reduces risk for other cancers as well that are impacted by disease, it makes sense.

Obesity links to an increased risk of ovarian cancer.  Let’s look at this no: Atlanta 2009/01/05 -A new epidemiological study has found that among women who have never used menopausal hormone therapy, obese women are at an increased risk of developing ovarian cancer compared with women of normal weight. Published in the February 15, 2009 issue of CANCER, a peer-reviewed journal of the American Cancer Society, the research indicates that obesity may contribute to the development of ovarian cancer through a hormonal mechanism. Ovarian cancer is the most fatal of gynecologic malignancies, and has a 5-year survival rate of only 37 percent.

To investigate this issue, Dr. Michael F. Leitzmann of the National Cancer Institute and colleagues studied 94,525 U.S. women aged 50 to 71 years over a period of seven years. The researchers documented 303 ovarian cancer cases during this time and noted that among women who had never taken hormones after menopause, obesity was associated with an almost 80 percent higher risk of ovarian cancer. In contrast, no link between body weight and ovarian cancer was evident for women who had ever used menopausal hormone therapy.

According to Dr. Leitzmann, these findings support the hypothesis that obesity may enhance ovarian cancer risk in part through its hormonal effects. Excess body mass in postmenopausal women leads to an increased production of estrogen, which in turn may stimulate the growth of ovarian cells and play a role in the development of ovarian cancer.

In another study done 2003, American Cancer Society researchers analyzed data based on 900,000 American adults with obesity and cancer that they monitored for a total of 16 years.  This is what they found in their landmark study: 1)The researchers found that the most obese women had a 62% increase in their risk of dying from cancer than women of normal weight; for obese men, the increase was 52%. The wide range of tumor types included colorectal, liver, gallbladder, pancreas, esophageal, kidney, prostate, breast, uterine, endometrial, and ovarian cancers. The researchers conclusion was that above-normal weight was associated with almost 20% of all cancer deaths in the United States. “There’s an incredibly powerful link between obesity and cancer,” says oncologist Joyce Slingerland of the University of Miami, Florida. “Everyone’s heard of obesity’s effect on heart disease and diabetes, and we’re now beginning to understand that the cancer risk is just as great,” she says.

Although researchers and epidemiologists had long suspected that diet and cancer were linked, efforts to explain why being fat makes cancer more deadly have only begun to deliver results in the past decade. 

So it is up to the people in society of that country they live in to take on responsible actions to make their country a better for all, not just one.  I say that is becoming as healthy as possible that an individual can reach and without America has the answers in knowing how to make this happen 100% in our country.

A new study from American Cancer Society researchers finds it’s not just how much physical activity you get, but how much time you spend sitting that can affect your risk of death.

My final study supporting how obesity links with cancer:

Just think if this was you or someone you know in the world and this happens to you or them; GOD FORBID, but you can help yourself through prevention with losing the weight or just staying slim and tone if you already are.  This will just decrease your risk of getting the cancer.

The JCCC study, led by Dr. Guido Eibl, JCCC member and professor-in-residence in the department of surgery at David Geffen School of Medicine, revealed that mice made obese with high-calorie, high-fat diets developed abnormally high numbers of these lesions.

This is the first study to show a direct causal link in an animal model between obesity and risk of this deadly pancreatic cancer.

 The JCCC study, led by Dr. Guido Eibl, JCCC member and professor-in-residence in the department of surgery at David Geffen School of Medicine, revealed that mice made obese with high-calorie, high-fat diets developed abnormally high numbers of these lesions. This is the first study to show a direct causal link in an animal model between obesity and risk of this deadly pancreatic cancer.

The mice eating the normal diet gained an average of approximately 7.2 g over 14 months. Mice on the high-fat, high-calorie diet more than doubled this with an average weight gain of 15.9 g.

Pathological tests showed that mice fed the normal diet had mostly normal pancreases with very few scattered PanIN lesions=intraepithelial neoplasias=precursors to pancreatic lesions.  They are used as markers but can only be seen microscopically so a biopsy is needed.  The mice fed high fat & cholesterol in their diet had significantly more PanIN lesions with less overall healthy pancreases.

The study showed that the mice fed a diet high in fats and calories gained significantly more weight, had abnormalities of their metabolism and increased insulin levels, and had marked pancreatic tissue inflammation with the development of PanIN lesions.

These observations suggest that such a diet like this which leads to weight gain, metabolism disturbances, pancreas inflammation and pancreas lesions that are precursors to cancer.

Obviously research is showing obesity has a link with cancer.  We now know this information let’s make a move America and people elsewhere to become a healthier nation including world.  For diversity is the US and other countries filled with all cultures, races and genders need to learn this knowledge to help make their country whether they were either born there and stayed or those born elsewhere moving to a new country, like America and we the people making up the country need to be responsible not just for yourselves but for your children and future generations in spreading good habits, good dieting, and good exercise to prevent high disease in the country for yourself and your children and the future generations by being a good role model in thinking=live healthy not unhealthy.  In time this would play an impact on your countries economy and health care system in how its run.  So come with me, like many others if you need to know the simple steps in how to go about losing weight safely but easy with learning better healthy habits and practicing some form of exercise which will benefit you in having a healthier body than join me at my website healthyusa.tsfl.com and become a member with getting guidance through Dr. Anderson on his healthy habits through his book and me as your health coach.  Take a peek you might just like what you see.  You make all the choices in what you want and going to the site costs nothing.  There will come a point you get your routine down and don’t need our help with staying healthy for life with decreasing your chance of so many diseases, not just cancer, from occurring.  Help me with so many others in tring to make a difference in America by becoming healthier.  Slowly but surely I am and I know you can to at your pace.

QUOTE FOR THURSDAY:

“Obesity was an independent predictor of recurrence.  We found that the more obese a man was, the greater the chances that his cancer would return after the surgery. The chance of recurrence for very obese patients is 70% higher than for others. That’s a very significant difference.”

Christopher Kane, MD, associate professor of urology at the University of California, San Francisco, and chief of urology at the San Francisco VA Hospital

The problem with being overweight or obese, as measured by weight and height, is that it raises our risk of chronic diseases like diabetes and heart disease.  But did you know that being obese can actually increase our risk of getting cancer and may even worsen our chances of surviving after a cancer diagnosis?  In fact, the American Cancer Society Cancer Prevention Study II showed significant increases in cancer occurrence in people who are the most overweight.  This link is stronger in some cancer types –including breast cancer after menopause, and cancers of the colon and rectum, pancreas, kidney, esophagus, and endometrium — and can be associated with a major increase in risk.

Being obese appears to be a problem for cancer survivors as well.  Studies have shown worse survival for obese women with breast cancer; obese men with prostate cancer are more likely to have an aggressive form of cancer and it is more likely to come back after surgery.  In light of this more recent data, the American Cancer Society recently released new healthy living guidelines for cancer survivors.

The relationship between body weight and cancer becomes more alarming when we consider just how many people in the United States are overweight or obese. Today, only 1/3 of adults are at a healthy body weight for their height. Another 1/3 are considered “overweight” and the remaining 1/3 are in the “obese” category. (About 17 % of children and adolescents are obese).  These rates are 300% higher than in 1980.) 

AMERICA wake up we have to turn this around for the better unless we don’t care about making this the home of the best country to live in a better one for all.  We need to get healthier people especially if you have a condition, illness or disease that will let you but always get clearance by your doctor before making changes; to maintain your safety.

In a few years, obesity will replace smoking as the number one preventable cause of many common cancers, according to Professor Jeffrey M. P. Holly, Ph.D. With a grant from American Institute of Cancer Research (AICR), Professor Holly is examining how fatty acids affect the actions of insulin-like growth factors (IGFs), which may promote cancer. He is also looking at two phytochemicals that may interfere with the actions of IGFs and form part of a diet to prevent cancer.

Obesity results from a long-term energy imbalance that increases a person’s storage of fat and circulating levels of fatty acids. These higher levels of fatty acids can cause resistance to insulin, which is a hormone essential to regulating the body’s metabolism. Insulin resistance has been associated with the development of diabetes, heart disease and certain cancers.

IGFs work in the body in a similar way to insulin. For a long time, Professor Holly, a Clinical Sciences Professor at the University of Bristol, U.K., has studied how these similar substances affect metabolic conditions such as diabetes. But for the past few years – as more recent research has shown that IGFs may be an important risk factor for colon, prostate and premenopausal breast cancer – he has looked at how obesity increases cancer risk through effects upon secretion and action of insulin and IGFs.

Recently, he and his research colleagues realized that “no one had looked at what effect eating fatty foods has on IGFs, especially now that we know that IGFs may be related to nutrition-dependent cancers.”

Focus on Two Fatty Acids

With funding from AICR (American Institute of Cancer Research), Dr. Holly and his research team have begun a series of experiments on malignant and healthy breast cells. They will see what impact the most abundant circulating fatty acids – palmitate and oleate – have on these cells by way of the production and activity of IGFs. Palmitate is a saturated fatty acid, while oleate is an unsaturated fatty acid.

“We’re looking at three aspects of these cells’ functions: their metabolism, their growth and their survival,” said Dr. Holly. “For cancer to develop, cell growth and survival are critical.”

Normally, when a cell becomes damaged, it is genetically programmed to die prematurely.  This process is called apoptosis.

IGFs, however, interfere with apoptosis. “IGFs are known to be the most potent, powerful signal in the body telling the cells not to commit suicide,” said Dr. Holly. “If there is too strong an IGF signal in the body, damaged cells may live and grow into tumors. That’s the most plausible link between high IGF levels and high rates of some cancers.”

Palmitate and oleate are known to affect insulin-related metabolic conditions differently. Palmitate appears to make the body more resistant to insulin, while oleate reduces resistance to insulin. But it is too early in Dr. Holly’s two-year experiment to know how the two fatty acids affect actions of IGF.

The Flavonoid Effect

As part of his AICR-funded project, Professor Holly will see whether two flavonoids – epigallocatechin-3-gallate (EGCG), found in green tea, and luteolin, found in olive oil – affect the growth of both the malignant and healthy cells. He will expose the cells to the flavonoids under various conditions to determine how strong their influence is.

Professor Holly chose to examine flavonoids as possible cancer-preventive agents in this obesity-related study because the fat we consume is not our body’s only source of fatty acids. Our bodies have the ability to make some of their own fatty acids when needed. In fact, certain cancers, like breast cancer, tend to make huge amounts in order to maintain their growth rate. Flavonoids are known to inhibit this process. This inhibition may partly explain why a diet high in vegetables and fruits protects against cancer in many studies.

Professor Holly suggests that the benefits of eating a lot of vegetables and fruits may be negated by a high-fat diet, because there would be a surplus of fatty acids to feed cells.

Although his research project is in a preliminary stage, the investigation is important because it could show how certain diets, especially those low in fat, can help prevent cancer. His study may also demonstrate that some diets may be more beneficial for people undergoing cancer treatment.

“Most treatments, like radiation therapy and chemotherapy, encourage cancer cells to die,” said Dr. Holly. “If we can manipulate the environment within the body to make cell death easier, these therapies may be more effective. One way to do this may be to turn off some of the signals from IGFs that encourage malignant cells to survive.”

Obesity is associated with increased risks of the following cancer types & possibly others as well:

Esophagus/Pancreas/Colon and rectum/Breast (after menopause) /Endometrium (lining of the uterus)/Kidney/Thyroid/Gallbladder

 One study, using NCI Surveillance, Epidemiology, and End Results (SEER) data, estimated that in 2007 in the United States, about 34,000 new cases of cancer in men (4 percent) and 50,500 in women (7 percent) were due to obesity. The percentage of cases attributed to obesity varied widely for different cancer types but was as high as 40 percent for some cancers, particularly endometrial cancer and esophageal adenocarcinoma.

A projection of the future health and economic burden of obesity in 2030 estimated that continuation of existing trends in obesity will lead to about 500,000 additional cases of cancer in the United States by 2030. This analysis also found that if every adult reduced their BMI by 1 percent, which would be equivalent to a weight loss of roughly 1 kg (or 2.2 lbs) for an adult of average weight, this would prevent the increase in the number of cancer cases and actually result in the avoidance of about 100,000 new cases of cancer.

Its a progressive bonedisease that is characterised by a decrease in bone mass and density and that leads to an increased risk of fracture.   In osteoporosis, the bone mineral density (BMD) is reduced, bone microarchitecture deteriorates, and the amount and variety of proteins in bone are altered.

 A weight bearing exercise is any exercise that has your legs and feet holding all of your weight. An example of this would be walking, yoga or even dancing.

The form of osteoporosis most common in women after menopause is referred to as primary type 1 or postmenopausal osteoporosis. Primary type 2 osteoporosis or senile osteoporosis occurs after age 75 and is seen in both females and males at a ratio of 2:1. Secondary osteoporosis may arise at any age and affect men and women equally. This form results from chronic predisposing medical problems or disease, or prolonged use of medications such as glucocorticoids, when the disease is called steroid- or glucocorticoid-induced osteoporosis.

The risk of osteoporosis fractures can be reduced with lifestyle changes and in those with previous osteoporosis related fractures medications. Lifestyle change includes diet, exercise, and preventing falls. The utility of calcium and vitamin D is questionable in most. Bisphosphonates are useful in those with previous fractures from osteoporosis but are of minimal benefit in those who have osteoporosis but no previous fractures. Osteoporosis is a component of the frailty syndrome.

Take the problem of Astronauts with osteoporosis:

Space travel has made it widely known that a stay outside the atmosphere – and thus outside the earth’s gravitational influence – disturbs the metabolism irreparably: the human body does not need any hard bones in zero-gravity, which leads to decalcification. A four year study of the ‘International Space Station’ showed that the bones of astronauts did not regenerate after even one year past their return to earth.

Anti-gravitational  training is the key to osteoporosis if you can handle it (like jumping on a trampeline)  Actual studies show that physical anti-gravitational activity helps the effected patients to regain their mobility and lessen the risk of bone fractures .

Benefits of exercise

Women who have been physically active throughout their lives generally have stronger bones than do women who have led more sedentary lives. But it’s never too late to start exercising. For postmenopausal women, regular physical activity can:

There’s no one-size-fits-all prescription.Before you startConsult your doctor before starting any exercise program for osteoporosis. You may need some tests first, including:

• Bone density measurement
