Alcoholism is a Disease

Many people ask, "what is alcoholism?" Alcoholism is a disease characterized by the habitual intake of alcohol. The definition of alcoholism is chronic alcohol use to the degree that it interferes with physical or mental health, or with normal social or work behavior.

Alcoholism is a disease that produces both physical and psychological addiction. Alcohol is a central nervous system depressant that reduces anxiety, inhibition, and feelings of guilt. It lowers alertness and impairs perception, judgment, and motor coordination. In high doses, it can cause loss of consciousness and even death. Alcoholism is a disease that damages the brain, liver, heart, and other organs (short-term, long-term effects of alcohol).

What is Alcoholism? - Signs and Symptoms

Spotting the signs and symptoms of alcoholism is not always easy. Alcoholism is a disease that can be seen through drinking-related arrests or job loss, but they tend to happen late in the disease.

Many signs occur earlier, yet are harder to detect. These signs include:

  • An increasing tolerance to the effects of alcohol. You may have heard the expression that someone can "hold their liquor." This is not a sign that this person will not have problems with alcohol; in fact, this may be an early sign of alcoholism as a disease.
  • A growing preoccupation with or interest in drinking. Also drinking alone or drinking before an activity where there will be drinking. It may seem as though one simply enjoys drinking. We now know that these can be part of the definition of alcoholism.
  • A person will dispute their drinking is a problem. This symptom, called denial, is almost always present in the disease of alcoholism. See alcoholic denial.

Later, difficulties in relationships, on the job, or with the law often occur.

Other signs and symptoms closely matching the definition of alcoholism are:

  • Hiding alcohol or sneaking drinks
  • Gulping the first few drinks
  • Wanting to drink more, or longer, than the rest of the crowd
  • Losing control of drinking, leading to attempts to control it ("going on the wagon")
