Alcoholism, or alcohol dependence, is a disease that causes the following:

• Craving – a strong need to drink
• Loss of control – not being able to stop drinking once you’ve started
• Physical dependence – withdrawal symptoms
• Tolerance – the need to drink more alcohol to feel the same effect

With alcohol abuse, you are not physically dependent, but you still have a serious problem. The drinking may cause problems at home, work, or school. It may cause you to put yourself in dangerous situations, or lead to legal or social problems.

*Alcohol use disorder (which includes a level that’s sometimes called alcoholism) is a pattern of alcohol use that involves problems controlling your drinking, being preoccupied with alcohol, continuing to use alcohol even when it causes problems, having to drink more to get the same effect, or having withdrawal symptoms when you rapidly decrease or stop drinking.Unhealthy alcohol use includes any alcohol use that puts your health or safety at risk or causes other alcohol-related problems. It also includes binge drinking — a pattern of drinking where a male consumes five or more drinks within two hours or a female downs at least four drinks within two hours. Binge drinking causes significant health and safety risks.  If your pattern of drinking results in repeated significant distress and problems functioning in your daily life, you likely have alcohol use disorder. It can range from mild to severe. However, even a mild disorder can escalate and lead to serious problems, so early treatment is important.

*Another common problem is binge drinking. It is drinking about five or more drinks in two hours for men. For women, it is about four or more drinks in two hours.

Too much alcohol is dangerous. Heavy drinking can increase the risk of certain cancers. It can cause damage to the liver, brain, and other organs. Drinking during pregnancy can harm your baby. Alcohol also increases the risk of death from car crashes, injuries, homicide, and suicide.

**Genetic, psychological, social and environmental factors can impact how drinking alcohol affects your body and behavior. Theories suggest that for certain people drinking has a different and stronger impact that can lead to alcohol use disorder.

Over time, drinking too much alcohol may change the normal function of the areas of your brain associated with the experience of pleasure, judgment and the ability to exercise control over your behavior. This may result in craving alcohol to try to restore good feelings or reduce negative ones.**

Alcohol use disorder can include periods of alcohol intoxication and symptoms of withdrawal.

Alcohol use disorder can be mild, moderate or severe, based on the number of symptoms you experience.

     *Signs and symptoms may include:

• Being unable to limit the amount of alcohol you drink
• Wanting to cut down on how much you drink or making unsuccessful attempts to do so
• Spending a lot of time drinking, getting alcohol or recovering from alcohol use
• Feeling a strong craving or urge to drink alcohol
• Failing to fulfill major obligations at work, school or home due to repeated alcohol use
• Continuing to drink alcohol even though you know it’s causing physical, social or interpersonal problems
• Giving up or reducing social and work activities and hobbies
• Using alcohol in situations where it’s not safe, such as when driving or swimming
• Developing a tolerance to alcohol so you need more to feel its effect or you have a reduced effect from the same amount
• Experiencing withdrawal symptoms — such as nausea, sweating and shaking — when you don’t drink, or drinking to avoid these symptoms
  

  *Risk factors for alcohol use disorder include:

• Steady drinking over time. Drinking too much on a regular basis for an extended period or binge drinking on a regular basis can lead to alcohol-related problems or alcohol use disorder.
• Age. People who begin drinking at an early age, and especially in a binge fashion, are at a higher risk of alcohol use disorder. Alcohol use may begin in the teens, but alcohol use disorder occurs more frequently in the 20s and 30s. However, it can begin at any age.
• Family history. The risk of alcohol use disorder is higher for people who have a parent or other close relative who has problems with alcohol. This may be influenced by genetic factors.
• Depression and other mental health problems. It’s common for people with a mental health disorder such as anxiety, depression, schizophrenia or bipolar disorder to have problems with alcohol or other substances.
• Social and cultural factors. Having friends or a close partner who drinks regularly could increase your risk of alcohol use disorder. The glamorous way that drinking is sometimes portrayed in the media also may send the message that it’s OK to drink too much. For young people, the influence of parents, peers and other role models can impact risk. @Alcohol withdrawal can occur when alcohol use has been heavy and prolonged and is then stopped or greatly reduced. It can occur within several hours to four or five days later. Symptoms include sweating, rapid heartbeat, hand tremors, problems sleeping, nausea and vomiting, hallucinations, restlessness and agitation, anxiety, and occasionally seizures. Symptoms can be severe enough to impair your ability to function at work or in social situations.
• Alcohol intoxication results as the amount of alcohol in your blood stream increases. The higher the blood alcohol concentration is, the more impaired you become. Alcohol intoxication causes behavior problems and mental changes. These may include inappropriate behavior, unstable moods, impaired judgment, slurred speech, impaired attention or memory, and poor coordination. You can also have periods called “blackouts,” where you don’t remember events. Very high blood alcohol levels can lead to coma or even death.
