Today’s section regarding Controllable Risk Factors you can change if needed which are:

Obesity

Studies have shown a clear association between obesity and increased risk of post-menopausal breast cancer. Because having more fat tissue can increase a woman’s level of estrogen, it is important for a woman to attempt to control her weight, particularly after menopause. Once a woman has stopped menstruating, her levels of estrogen and progesterone are much lower than they once were. Excess fat tissue may cause significant increases in her hormone levels.

Physical Activity

Physical activity not only helps a woman reduce her risk of breast cancer by maintaining a healthy body weight, it may also have its own benefits to risk reduction. Some studies have shown that physical exercise throughout a woman’s life reduces her risk, independent of her weight.

One theory is that exercise may reduce a woman’s risk by limiting menstrual function, and it has been observed that regular physical exercise can delay menarche — the onset of menstruation — when body fat percentage is low. Since breast cancer risk may be significantly influenced by a woman’s lifetime exposure to hormones, reducing that exposure may also reduce her risk.

Alcohol Consumption

Many epidemiological studies spanning the past 20 years have shown an association between alcohol consumption and increased risk of breast cancer. Studies have consistently found that women who consume at least three alcoholic drinks per day are at higher risk for developing breast cancer than women who do not drink alcohol. Furthermore, study findings have shown that for women who drink two alcoholic drinks or more per day, breast cancer risk is related to the amount of alcohol consumed — higher consumption of alcohol equals higher breast cancer risk.

Among other mechanisms, it has been suggested that alcohol may increase a woman’s hormone levels. A recent study fed women specified amounts of alcohol each day, and demonstrated that a woman’s levels of blood estrogen did increase according to the amount of alcohol she consumed. In particular, the breast cancer risk of post-menopausal women, whose bodies make very little estrogen compared with pre-menopausal women, may be affected by alcohol consumption by this mechanism.

Hormone Replacement Therapy

A study conducted by the Women’s Health Initiative (WHI) showed that women in the study population who took hormone replacement therapy — combined estrogen and progestin — had a 26 percent increased risk (relative to an average woman) of invasive breast cancer after four to five years of therapy. This finding is consistent with the growing evidence that exogenous (outside) hormones increase a woman’s lifetime estrogen exposure as well as increasing her breast cancer risk.

Breastfeeding

An analysis published in July 2002 pulled together data from 47 previous studies to show that breastfeeding does in fact slightly lower a woman’s risk of breast cancer. The longer a woman breastfed, the lower her risk was. For optimal benefit, we recommend breastfeeding a child for 12 months.  The hormonal balance is different than a non pregnant women who does not breast feed 12 months.

The decision of whether or not to breastfeed is certainly a very personal one. The knowledge that breastfeeding may offer a slight reduction in risk for developing breast cancer is just one of the many factors that will influence how long a woman decides to breastfeed.

“Breast cancer occurs nearly 100 times more often in women than in men. Age: Two out of three women with invasive cancer are diagnosed after age 55.“

National Breast Cancer Foundation (www.nationalbreastcancer.org)

“Benign (non-cancerous) breast conditions are very common, and most women have them. In fact, most breast changes are benign.  Unlike breast cancers, benign breast conditions are not life-threatening.  But some are linked with a higher risk of getting breast cancer later on.”

American Cancer Society

Pulmonary embolism (PULL-mun-ary EM-bo-lizm), or PE, is a sudden blockage in a lung artery. The blockage usually is caused by a blood clot that travels to the lung from a vein in the leg.  The clot gets to the right side of the heart and goes into the upper chamber (atrium) down to the lower chamber (ventricles) to the pulmonary artery bringing the clot into the lungs.

A clot that forms in one part of the body and travels in the bloodstream to another part of the body is called an embolus (EM-bo-lus).

PE is a serious condition that can:

• Damage part of your lung because of a lack of blood flow to your lung tissue. This damage may lead to pulmonary hypertension (increased pressure in the pulmonary arteries).
• Cause low oxygen levels in your blood.
• Damage other organs in your body because of a lack of oxygen.

If a blood clot is large, or if there are many clots, PE can cause death.

Overview

PE most often is a complication of a condition called deep vein thrombosis (DVT). In DVT, blood clots form in the deep veins of the body—most often in the legs. These clots can break free, travel through the bloodstream to the lungs, and block an artery.

Deep vein clots are not like clots in veins close to the skin’s surface. Those clots remain in place and do not cause PE.

Outlook

The exact number of people affected by DVT and PE isn’t known. Estimates suggest these conditions affect 300,000 to 600,000 people in the United States each year.

If left untreated, about 30 percent of patients who have PE will die. Most of those who die do so within the first few hours of the event.

The good news is that a prompt diagnosis and proper treatment can save lives and help prevent the complications of PE.

Other Names for Pulmonary Embolism

• Venous thromboembolism (VTE). This term is used for both pulmonary embolism and deep vein thrombosis.

What Causes Pulmonary Embolism?

Major Causes

Pulmonary embolism (PE) usually begins as a blood clot in a deep vein of the leg. This condition is called deep vein thrombosis. The clot can break free, travel through the bloodstream to the lungs, and block an artery.

Blood clots can form in the deep veins of the legs if blood flow is restricted and slows down. This can happen if you don’t move around for long periods, such as:

• After some types of surgery
• During a long trip in a car or airplane
• If you must stay in bed for an extended time

Blood clots are more likely to develop in veins damaged from surgery or injured in other ways.

Other Causes

Rarely, an air bubble, part of a tumor, or other tissue travels to the lungs and causes PE. Also, if a large bone in the body (such as the thigh bone) breaks, fat from the bone marrow can travel through the blood. If the fat reaches the lungs, it can cause PE.

Who Is at Risk for Pulmonary Embolism?

Pulmonary embolism (PE) occurs equally in men and women. The risk increases with age. For every 10 years after age 60, the risk of having PE doubles.

Certain inherited conditions, such as factor V Leiden, increase the risk of blood clotting and PE.

Major Risk Factors

Your risk for PE is high if you have deep vein thrombosis (DVT) or a history of DVT. In DVT, blood clots form in the deep veins of the body—most often in the legs. These clots can break free, travel through the bloodstream to the lungs, and block an artery.

Your risk for PE also is high if you’ve had the condition before.

Other Risk Factors

Other factors also can increase the risk for PE, such as:

• Being bedridden or unable to move around much
• Having surgery or breaking a bone (the risk goes up in the weeks following the surgery or injury)
• Having certain diseases or conditions, such as a stroke, paralysis (an inability to move), chronic heart disease, or high blood pressure
• Smoking

People who have recently been treated for cancer or who have a central venous catheter are more likely to develop DVT, which increases their risk for PE. A central venous catheter is a tube placed in a vein to allow easy access to the bloodstream for medical treatment.  A clot can form at the end of it but usually in preventing this if not heparin bolus (ex.300 U in 5 cc of normal saline) is flushed in the catheter if not just flushing the catheter with 10cc of normal saline the prevent the clot forming every 8 hrs or 12 hrs.

Other risk factors for DVT include sitting for long periods (such as during long car or airplane rides), pregnancy and the 6-week period after pregnancy, and being overweight or obese. Women who take hormone therapy pills or birth control pills also are at increased risk for DVT.

The risk of developing blood clots increases as your number of risk factors increases.

What Are the Signs and Symptoms of Pulmonary Embolism?

Major Signs and Symptoms

Signs and symptoms of pulmonary embolism (PE) include unexplained shortness of breath, problems breathing, chest pain, coughing, or coughing up blood. An arrhythmia (irregular heartbeat) also may suggest that you have PE.

Sometimes the only signs and symptoms are related to deep vein thrombosis (DVT). These include swelling of the leg or along a vein in the leg, pain or tenderness in the leg, a feeling of increased warmth in the area of the leg that’s swollen or tender, and red or discolored skin on the affected leg.

See your doctor right away if you have any signs or symptoms of PE or DVT. It’s also possible to have PE and not have any signs or symptoms.

Other Signs and Symptoms

Some people who have PE have feelings of anxiety or dread, light-headedness or fainting, rapid breathing, sweating, or an increased heart rate.

How Is Pulmonary Embolism Diagnosed?

Pulmonary embolism (PE) is diagnosed based on your medical history, a physical exam, and test results.

Doctors who treat patients in the emergency room often are the ones to diagnose PE with the help of a radiologist. A radiologist is a doctor who deals with x rays and other similar tests.

Medical History and Physical Exam

To diagnose PE, the doctor will ask about your medical history. He or she will want to:

• Find out your deep vein thrombosis (DVT) and PE risk factors
• See how likely it is that you could have PE
• Rule out other possible causes for your symptoms

Your doctor also will do a physical exam. During the exam, he or she will check your legs for signs of DVT. He or she also will check your blood pressure and your heart and lungs.

Diagnostic Tests

Many tests can help diagnose PE. Which tests you have will depend on how you feel when you get to the hospital, your risk factors, available testing options, and other conditions you could possibly have. You may have one or more of the following tests.

Ultrasound

Doctors can use ultrasound to look for blood clots in your legs. Ultrasound uses sound waves to check blood flow in your veins.

For this test, gel is put on the skin of your legs. A hand-held device called a transducer is moved back and forth over the affected areas. The transducer gives off ultrasound waves and detects their echoes as they bounce off the vein walls and blood cells.

A computer turns the echoes into a picture on a computer screen, allowing the doctor to see blood flow in your legs. If the doctor finds blood clots in the deep veins of your legs, he or she will recommend treatment.

DVT and PE both are treated with the same medicines.

Computed Tomography Scans

Doctors can use computed tomography (to-MOG-rah-fee) scans, or CT scans, to look for blood clots in the lungs and legs.

For this test, dye is injected into a vein in your arm. The dye makes the blood vessels in your lungs and legs show up on x-ray images. You’ll lie on a table, and an x-ray tube will rotate around you. The tube will take pictures from many angles.

This test allows doctors to detect most cases of PE. The test only takes a few minutes. Results are available shortly after the scan is done.

Lung Ventilation/Perfusion Scan

A lung ventilation/perfusion scan, or VQ scan, uses a radioactive substance to show how well oxygen and blood are flowing to all areas of your lungs. This test can help detect PE.

Pulmonary Angiography

Pulmonary angiography (an-jee-OG-rah-fee) is another test used to diagnose PE. This test isn’t available at all hospitals, and a trained specialist must do the test.

For this test, a flexible tube called a catheter is threaded through the groin (upper thigh) or arm to the blood vessels in the lungs. Dye is injected into the blood vessels through the catheter.

X-ray pictures are taken to show blood flowing through the blood vessels in the lungs. If a blood clot is found, your doctor may use the catheter to remove it or deliver medicine to dissolve it.

Blood Tests

Certain blood tests may help your doctor find out whether you’re likely to have PE.

A D-dimer test measures a substance in the blood that’s released when a blood clot breaks down. High levels of the substance may mean a clot is present. If your test is normal and you have few risk factors, PE isn’t likely.

Other blood tests check for inherited disorders that cause blood clots. Blood tests also can measure the amount of oxygen and carbon dioxide in your blood. A clot in a blood vessel in your lungs may lower the level of oxygen in your blood.

Other Tests

To rule out other possible causes of your symptoms, your doctor may use one or more of the following tests.

• Echocardiography (echo). This test uses sound waves to create a moving picture of your heart. Doctors use echo to check heart function and detect blood clots inside the heart.
• EKG (electrocardiogram). An EKG is a simple, painless test that detects and records the heart’s electrical activity.
• Chest x ray. This test creates pictures of your lungs, heart, large arteries, ribs, and diaphragm (the muscle below your lungs).
• Chest MRI (magnetic resonance imaging). This test uses radio waves and magnetic fields to create pictures of organs and structures inside the body. MRI often can provide more information than an x ray.

How Is Pulmonary Embolism Treated?

Pulmonary embolism (PE) is treated with medicines, procedures, and other therapies. The main goals of treating PE are to stop the blood clot from getting bigger and keep new clots from forming.

Treatment may include medicines to thin the blood and slow its ability to clot. If your symptoms are life threatening, your doctor may give you medicine to quickly dissolve the clot. Rarely, your doctor may use surgery or another procedure to remove the clot.

Medicines

Anticoagulants (AN-te-ko-AG-u-lants), or blood thinners, decrease your blood’s ability to clot. They’re used to stop blood clots from getting larger and prevent clots from forming. Blood thinners don’t break up blood clots that have already formed. (The body dissolves most clots with time.)

You can take blood thinners as either a pill, an injection, or through a needle or tube inserted into a vein (called intravenous, or IV, injection). Warfarin is given as a pill. (Coumadin^® is a common brand name for warfarin.) Heparin is given as an injection or through an IV tube; usually given as Heparin drip than when Counmadin starts within 24 hrs the drip is discontinued in the hospital and the patient stays on coumadin or some type of blood thinner as the MD prescribes.

At times, your doctor may treat you with both heparin and warfarin at the same time. Heparin acts quickly. Warfarin takes 2 to 3 days before it starts to work. Once warfarin starts to work, heparin usually is stopped.

Pregnant women usually are treated with heparin only, because warfarin is dangerous for the pregnancy.

If you have deep vein thrombosis, treatment with blood thinners usually lasts for 3 to 6 months. If you’ve had blood clots before, you may need a longer period of treatment. If you’re being treated for another illness, such as cancer, you may need to take blood thinners as long as PE risk factors are present.

The most common side effect of blood thinners is bleeding. This can happen if the medicine thins your blood too much. This side effect can be life threatening.

Sometimes the bleeding is internal, which is why people treated with blood thinners usually have routine blood tests. These tests, called PT and PTT tests, measure the blood’s ability to clot. These tests also help your doctor make sure you’re taking the right amount of medicine. Call your doctor right away if you’re bruising or bleeding easily.

Thrombin inhibitors are a newer type of blood-thinning medicine. They’re used to treat some types of blood clots in people who can’t take heparin.

Emergency Treatment

When PE is life threatening, a doctor may use treatments that remove or break up the blood clot. These treatments are given in an emergency room or hospital.

Thrombolytics (THROM-bo-LIT-iks) are medicines that can quickly dissolve a blood clot. They’re used to treat large clots that cause severe symptoms. Because thrombolytics can cause sudden bleeding, they’re used only in life-threatening situations.

Sometimes a doctor may use a catheter (a flexible tube) to reach the blood clot. The catheter is inserted into a vein in the groin (upper thigh) or arm and threaded to the clot in the lung. The doctor may use the catheter to remove the clot or deliver medicine to dissolve it.

Rarely, surgery may be needed to remove the blood clot.

Other Types of Treatment

If you can’t take medicines to thin your blood, or if the medicines don’t work, your doctor may suggest a vena cava filter. This device keeps blood clots from traveling to your lungs.

The filter is inserted inside a large vein called the inferior vena cava. (This vein carries blood from the body back to the heart). The filter catches clots before they travel to the lungs. This type of treatment can prevent PE, but it won’t stop other blood clots from forming.

Graduated compression stockings can reduce the chronic (ongoing) swelling that a blood clot in the leg may cause.

Graduated compression stockings are worn on the legs from the arch of the foot to just above or below the knee. These stockings are tight at the ankle and become looser as they go up the leg. This causes gentle compression (pressure) up the leg. The pressure keeps blood from pooling and clotting.

“The kidneys are important because they keep the composition, or makeup, of the blood stable, which lets the body function.  The kidneys filter our blood.”

National Institute of Diabetes and Digestive and Kidney Diseases (nih.gov).

The kidneys are important organs with many functions in the body, including producing hormones, absorbing minerals, and filtering blood and producing urine. While they are important and kidney failure can be fatal, a human only needs one healthy kidney to survive.

The kidneys are two bean-shaped organs that extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body.

They reside against the back muscles in the upper abdominal cavity. They sit opposite each other on either side of the spine. The right kidney sits a little bit lower than the left to accommodate the liver.

When it comes to components of the urinary system, the kidneys are multi-functional powerhouses of activity, for if the kidneys aren’t working, meaning they don’t filter toxic wastes out of our blood stream (with other functions it does) than the waste products don’t get dumped into the urinary bladder from the renal tubes, called right and left ureters. In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. If the kidneys are not working they are not filtering our blood (same principle as filtering beer to make it to perfection, the kidneys do it for our blood to be able to have the cells do their function to the optimal levels with keeping toxins out of the body in preventing many blood problems with more due to acidosis (toxin build up). In the adult, the ureters are usually 25–30 cm (10–12 in) long and ~3–4 mm in diameter.

The kidneys have multiple functions.

Some of the core actions of a healthy kidney or kidneys of a human body include:

• Waste excretion: There are many things your body doesn’t want inside of it. The kidneys filter out toxins, excess salts, and urea (a toxin), a nitrogen-based waste created by cell metabolism.
•  * Urea is an organic chemical compound and is essentially the waste produced by the body after metabolizing protein. Naturally the compound urea is produced when the liver breaks down protein or amino acids, and ammonia, the kidneys then transfer the urea from the blood to the urine, when they do filtering of the blood.
• * Urea is a byproduct of protein metabolism, the ending result.                                                                   *Extra nitrogen is expelled from the body through urea because it is extremely soluble (solid); it is a very efficient process. The average person excretes about 30 grams of urea a day, mostly through urine but a small amount is also secreted in perspiration. Synthetic versions of the chemical compound can be created in liquid or solid form and is often an ingredient found in fertilizers, animal food, and diuretics, just to name a few . Urea is what gives our urine the color yellow.                                                                                                                                                                                                 *In the gastrointestinal tract, blood proteins are broken down into ammonia (could be due to high protein eating to drugs with actual conditions); and goes to the liver converting it to Urea. It is then released into the blood stream where the kidney’s take it up and eliminate it. Urea is then eliminated by the kidney’s, but not produced by it.
• Urea is synthesized in the liver and transported through the blood to the kidneys for removal.

• A Healthy Kidney or Kidneys functions in the human body:

• Water level balancing: As the kidneys are key in the chemical breakdown of urine, they react to changes in the body’s water level throughout the day. As water intake decreases, the kidneys adjust accordingly and leave water in the body instead of helping excrete it which aides in electrolyte balancing in the blood with keeping the body hydrated properly.
• Blood pressure regulation: The kidneys need constant pressure to filter the blood. When it drops too low, the kidneys increase the pressure. One way is by producing a blood vessel-constricting protein (angiotensin) that also signals the body to retain sodium and water. Both the constriction and retention help restore normal blood pressure.
• Red blood cell regulation: When the kidneys don’t get enough oxygen, they send out a distress call in the form of erythropoietin, a hormone that stimulates the bone marrow to produce more oxygen-carrying red blood cells.
• Acid regulation: As cells metabolize, they produce acids. Foods we eat can either increase the acid in our body or neutralize it. If the body is to function properly, it needs to keep a healthy balance of these chemicals. The kidneys do that, too.Because of all of the vital functions the kidneys perform and the toxins they encounter, the kidneys are susceptible to various problems.

• Most people are born with two kidneys, but many people can live on just one. Kidney transplant surgeries with live donors are common medical procedures today.

• Acute kidney failure is a condition in which the kidneys suddenly lose their ability to function properly. This can occur for many reasons, including:

• Infection
• Blood-clotting disorders
• Decreased blood flow caused by low blood pressure
• Autoimmune kidney disorders
• Urinary tract infections
• Complications from pregnancy
• Dehydration.
• Chronic kidney failure – same as acute in that the kidney (s) loses its function.
• Diseases and conditions that commonly cause chronic kidney disease include:

• Type 1 or type 2 diabetes
• High blood pressure
• Glomerulonephritis (gloe-mer-u-lo-nuh-FRY-tis), an inflammation of the kidney’s filtering units (glomeruli)
• Interstitial nephritis, an inflammation of the kidney’s tubules and surrounding structures
• Polycystic kidney disease
• Prolonged obstruction of the urinary tract, from conditions such as enlarged prostate, kidney stones and some cancers
• Vesicoureteral (ves-ih-koe-yoo-REE-ter-ul) reflux, a condition that causes urine to back up into your kidneys
• Recurrent kidney infection, also called pyelonephritis (pie-uh-lo-nuh-FRY-tis)
• A chronic condition caused the failure to happen called a secondary diagnosis.

“When beginning a weight loss diet, it is tempting to try to lose weight as quickly as you can. However, not only are crash or fad diets highly likely to fail, they can also have a significant negative impact on your health.  A low-carb diet is generally used for losing weight. Some low-carb diets may have health benefits beyond weight loss, such as reducing risk factors associated with type 2 diabetes and metabolic syndrome. ”
