What is alcohol use disorder (AUD)?

AUD is a medical condition that causes problems with alcohol use. You are not able to control alcohol use even though it causes negative effects. AUD includes alcohol abuse and alcohol dependence. Alcohol abuse means you drink more than the recommended daily or weekly limits. Alcohol dependence means you have withdrawal symptoms after not drinking for a short period.

What are the signs and symptoms of AUD?

Your healthcare provider will ask you about your alcohol use. Mild AUD means you had 2 to 3 of the following over the last 12 months. Moderate means you have 4 to 5. Severe means you have 6 or more.

  • You have tried to decrease or stop drinking more than one time. You continue drinking even after you quit. You have had more to drink than you planned, or you drank for a longer time than you intended.
  • You crave alcohol. You have a desire to drink more often or to drink larger amounts of alcohol. You have a hard time thinking about anything other than alcohol.
  • You put extra effort and time into drinking alcohol. You often go to events or activities that will include drinking. You spend much of your time drinking alcohol or being with people who also drink.
  • You spend less time doing important activities. You have trouble taking part in social or daily activities at school, work, or home.
  • You have given up activities that you like. You drink instead of doing the activities. You also spend a lot of time recovering from the effects of drinking.
  • You continue to drink even though it causes health or relationship problems. You may have problems with your family, friends, or coworkers but continue to drink.
  • You develop alcohol tolerance. Tolerance means the amount of alcohol you usually drink no longer causes the effects you desire. You need to drink more alcohol to get the same effects.
  • You have withdrawal (physical or mental) symptoms after not drinking for a short period. Alcohol is needed to relieve or prevent withdrawal symptoms such as tremors (shakes). You may also have to drink to stop withdrawal symptoms or to cure a hangover.
  • You put yourself in physically dangerous settings while drinking. Examples include driving a car or having unprotected sex after drinking.

What health problems can AUD cause?

  • Cancer in your liver, pancreas, stomach, colon, kidney, or breast
  • Stroke or a heart attack
  • Liver, kidney, or lung disease
  • Blackouts, memory loss, brain damage, or dementia
  • Diabetes, immune system problems, or thiamine (vitamin B1) deficiency
  • Problems for you and your baby if you drink while pregnant

How is AUD treated?

Do not try to stop drinking on your own. Your healthcare provider may admit you to the hospital to help you withdraw from alcohol safely. Then you may need any of the following:

  • Medicines to decrease your craving for alcohol
  • Support groups such as Alcoholics Anonymous
  • Therapy services from a psychiatrist or psychologist
  • Admission to an inpatient facility for treatment for severe dependence
