There is no single gene that is responsible for alcoholism. There are hundreds of genes in a person’s DNA that may increase the risk of developing alcoholism. There are also environmental risk factors, psychological and social factors.

Alcohol withdrawal occurs when someone who uses alcohol heavily suddenly stops. Symptoms of alcohol withdrawal include rapid heartbeat, hand tremors, sweating, insomnia, hallucinations, nausea, anxiety and restlessness. Occasionally someone experiencing alcohol withdrawal may have seizures.

Many people with depression or anxiety self-medicate with alcohol. While drinking may make you feel calmer and happier in the moment, it can actually make depression and anxiety worse in the long run. Alcohol is a depressant, and may increase feelings of despair, distress and anxiety.

Many people with alcoholism don't get adequate nutrition and skip meals. During recovery, eating a diet rich in fruits, vegetables and whole grains will help repair the body. Eating foods that are high in complex carbohydrates will help balance the levels of serotonin (sometimes called the happy hormone) in the brain. Incorporating B-complex vitamins such as folic acid, B12 and thiamine into the diet will replenish vitamins that have been lost.

Studies have shown that various types of exercise can increase dopamine levels in the brain, improve sleep and relieve stress and anxiety. And of course, exercise is great for your physical health, too.
