Alcohol use disorder

Overview

Alcohol use disorder is a pattern of alcohol use that involves problems controlling your drinking, being preoccupied with alcohol or continuing to use alcohol even when it causes problems. This disorder also involves having to drink more to get the same effect or having withdrawal symptoms when you rapidly decrease or stop drinking. Alcohol use disorder includes a level of drinking that's sometimes called alcoholism.

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 has five or more drinks within two hours or a female has 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.

Symptoms

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, work or relationship problems
Giving up or reducing social and work activities and hobbies to use alcohol
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

Alcohol use disorder can include periods of being drunk (alcohol intoxication) and symptoms of withdrawal.

Alcohol intoxication results as the amount of alcohol in your bloodstream increases. The higher the blood alcohol concentration is, the more likely you are to have bad effects. Alcohol intoxication causes behavior problems and mental changes. These may include inappropriate behavior, unstable moods, poor judgment, slurred speech, problems with 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, permanent brain damage or even death.
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 4 to 5 days later. Signs and 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.

What is considered 1 drink?

The National Institute on Alcohol Abuse and Alcoholism defines one standard drink as any one of these:

12 ounces (355 milliliters) of regular beer (about 5% alcohol)
8 to 9 ounces (237 to 266 milliliters) of malt liquor (about 7% alcohol)
5 ounces (148 milliliters) of wine (about 12% alcohol)
1.5 ounces (44 milliliters) of hard liquor or distilled spirits (about 40% alcohol)

When to see a doctor

If you feel that you sometimes drink too much alcohol, or your drinking is causing problems, or if your family is concerned about your drinking, talk with your health care provider. Other ways to get help include talking with a mental health professional or seeking help from a support group such as Alcoholics Anonymous or a similar type of self-help group.

Because denial is common, you may feel like you don't have a problem with drinking. You might not recognize how much you drink or how many problems in your life are related to alcohol use. Listen to relatives, friends or co-workers when they ask you to examine your drinking habits or to seek help. Consider talking with someone who has had a problem with drinking but has stopped.

If your loved one needs help

Many people with alcohol use disorder hesitate to get treatment because they don't recognize that they have a problem. An intervention from loved ones can help some people recognize and accept that they need professional help. If you're concerned about someone who drinks too much, ask a professional experienced in alcohol treatment for advice on how to approach that person.

Causes

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.

Risk factors

Alcohol use may begin in the teens, but alcohol use disorder occurs more frequently in the 20s and 30s, though it can start at any age.

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.
Starting at an early age. People who begin drinking — especially binge drinking — at an early age are at a higher risk of alcohol use disorder.
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.
History of trauma. People with a history of emotional trauma or other trauma are at increased risk of alcohol use disorder.
Having bariatric surgery. Some research studies indicate that having bariatric surgery may increase the risk of developing alcohol use disorder or of relapsing after recovering from alcohol use disorder.
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.

Complications

Alcohol depresses your central nervous system. In some people, the initial reaction may feel like an increase in energy. But as you continue to drink, you become drowsy and have less control over your actions.

Too much alcohol affects your speech, muscle coordination and vital centers of your brain. A heavy drinking binge may even cause a life-threatening coma or death. This is of particular concern when you're taking certain medications that also depress the brain's function.

Impact on your safety

Excessive drinking can reduce your judgment skills and lower inhibitions, leading to poor choices and dangerous situations or behaviors, including:

Motor vehicle accidents and other types of accidental injury, such as drowning
Relationship problems
Poor performance at work or school
Increased likelihood of committing violent crimes or being the victim of a crime
Legal problems or problems with employment or finances
Problems with other substance use
Engaging in risky, unprotected sex, or experiencing sexual abuse or date rape
Increased risk of attempted or completed suicide

Impact on your health

Drinking too much alcohol on a single occasion or over time can cause health problems, including:

Liver disease. Heavy drinking can cause increased fat in the liver (hepatic steatosis) and inflammation of the liver (alcoholic hepatitis). Over time, heavy drinking can cause irreversible destruction and scarring of liver tissue (cirrhosis).
Digestive problems. Heavy drinking can result in inflammation of the stomach lining (gastritis), as well as stomach and esophageal ulcers. It can also interfere with your body's ability to get enough B vitamins and other nutrients. Heavy drinking can damage your pancreas or lead to inflammation of the pancreas (pancreatitis).
Heart problems. Excessive drinking can lead to high blood pressure and increases your risk of an enlarged heart, heart failure or stroke. Even a single binge can cause serious irregular heartbeats (arrhythmia) called atrial fibrillation.
Diabetes complications. Alcohol interferes with the release of glucose from your liver and can increase the risk of low blood sugar (hypoglycemia). This is dangerous if you have diabetes and are already taking insulin or some other diabetes medications to lower your blood sugar level.
Issues with sexual function and periods. Heavy drinking can cause men to have difficulty maintaining an erection (erectile dysfunction). In women, heavy drinking can interrupt menstrual periods.
Eye problems. Over time, heavy drinking can cause involuntary rapid eye movement (nystagmus) as well as weakness and paralysis of your eye muscles due to a deficiency of vitamin B-1 (thiamin). A thiamin deficiency can result in other brain changes, such as irreversible dementia, if not promptly treated.
Birth defects. Alcohol use during pregnancy may cause miscarriage. It may also cause fetal alcohol spectrum disorders (FASDs). FASDs can cause a child to be born with physical and developmental problems that last a lifetime.
Bone damage. Alcohol may interfere with making new bone. Bone loss can lead to thinning bones (osteoporosis) and an increased risk of fractures. Alcohol can also damage bone marrow, which makes blood cells. This can cause a low platelet count, which may result in bruising and bleeding.
Neurological complications. Excessive drinking can affect your nervous system, causing numbness and pain in your hands and feet, disordered thinking, dementia, and short-term memory loss.
Weakened immune system. Excessive alcohol use can make it harder for your body to resist disease, increasing your risk of various illnesses, especially pneumonia.
Increased risk of cancer. Long-term, excessive alcohol use has been linked to a higher risk of many cancers, including mouth, throat, liver, esophagus, colon and breast cancers. Even moderate drinking can increase the risk of breast cancer.
Medication and alcohol interactions. Some medications interact with alcohol, increasing its toxic effects. Drinking while taking these medications can either increase or decrease their effectiveness, or make them dangerous.

Prevention

Early intervention can prevent alcohol-related problems in teens. If you have a teenager, be alert to signs and symptoms that may indicate a problem with alcohol:

Loss of interest in activities and hobbies and in personal appearance
Red eyes, slurred speech, problems with coordination and memory lapses
Difficulties or changes in relationships with friends, such as joining a new crowd
Declining grades and problems in school
Frequent mood changes and defensive behavior

You can help prevent teenage alcohol use:

Set a good example with your own alcohol use.
Talk openly with your child, spend quality time together and become actively involved in your child's life.
Let your child know what behavior you expect — and what the consequences will be for not following the rules.

Diagnosis

You're likely to start by seeing your primary health care provider. If your provider suspects that you have a problem with alcohol, you may be referred to a mental health provider.

To assess your problem with alcohol, your provider will likely:

Ask you some questions related to your drinking habits. The provider may ask for permission to speak with family members or friends. However, confidentiality laws prevent your provider from giving out any information about you without your consent.
Perform a physical exam. Your health care provider may do a physical exam and ask questions about your health. There are many physical signs that indicate complications of alcohol use.
Suggest lab tests and imaging tests. While there are no specific tests to diagnose alcohol use disorder, certain patterns of lab test results may strongly suggest it. And you may need tests to identify health problems that may be linked to your alcohol use. Damage to your organs may be seen on tests.
Complete a psychological evaluation. This evaluation includes questions about your symptoms, thoughts, feelings and behavior patterns. You may be asked to complete a questionnaire to help answer these questions.

Treatment

Treatment for alcohol use disorder can vary, depending on your needs. Treatment may involve a brief intervention, individual or group counseling, an outpatient program, or a residential inpatient stay. Working to stop alcohol use to improve quality of life is the main treatment goal.

Treatment for alcohol use disorder may include:

Detox and withdrawal. Treatment may begin with a program of detoxification — withdrawal that's medically managed. Sometimes called detox, this generally takes 2 to 7 days. You may need to take sedating medications to prevent withdrawal symptoms. Detox is usually done at an inpatient treatment center or a hospital.
Learning new skills and making a treatment plan. This process usually involves alcohol treatment specialists. It may include goal setting, behavior change techniques, use of self-help manuals, counseling and follow-up care at a treatment center.
Psychological counseling. Counseling and therapy for groups and individuals help you better understand your problem with alcohol and support recovery from the psychological aspects of alcohol use. You may benefit from couples or family therapy — family support can be an important part of the recovery process.
Oral medications. A drug called disulfiram may help prevent you from drinking, although it won't cure alcohol use disorder or remove the urge to drink. If you drink alcohol while taking disulfiram, the drug produces a physical reaction that may include flushing, nausea, vomiting and headaches.

Naltrexone, a drug that blocks the good feelings alcohol causes, may prevent heavy drinking and reduce the urge to drink. Acamprosate may help you combat alcohol cravings once you stop drinking. Unlike disulfiram, naltrexone and acamprosate don't make you feel sick after taking a drink.
Injected medication. Vivitrol, a version of the drug naltrexone, is injected once a month by a health care professional. Although similar medication can be taken in pill form, the injectable version of the drug may be easier for people recovering from alcohol use disorder to use consistently.
Continuing support. Aftercare programs and support groups help people recovering from alcohol use disorder to stop drinking, manage relapses and cope with necessary lifestyle changes. This may include medical or psychological care or attending a support group.
Treatment for psychological problems. Alcohol use disorder commonly occurs along with other mental health disorders. If you have depression, anxiety or another mental health condition, you may need talk therapy (psychotherapy), medications or other treatment.
Medical treatment for health conditions. Many alcohol-related health problems improve significantly once you stop drinking. But some health conditions may warrant continued treatment and follow-up care.
Spiritual practice. People who are involved with some type of regular spiritual practice may find it easier to maintain recovery from alcohol use disorder or other addictions. For many people, gaining greater insight into their spiritual side is a key element in recovery.

Residential treatment programs

For serious alcohol use disorder, you may need a stay at a residential treatment facility. Most residential treatment programs include individual and group therapy, support groups, educational lectures, family involvement, and activity therapy.

Residential treatment programs typically include licensed alcohol and drug counselors, social workers, nurses, doctors, and others with expertise and experience in treating alcohol use disorder.

Alternative medicine

Avoid replacing conventional medical treatment or psychotherapy with alternative medicine. But if used in addition to your treatment plan when recovering from alcohol use disorder, these techniques may be helpful:

Yoga. Yoga's series of postures and controlled breathing exercises may help you relax and manage stress.
Meditation. During meditation, you focus your attention and eliminate the stream of jumbled thoughts that may be crowding your mind and causing stress.
Acupuncture. With acupuncture, hair-thin needles are inserted under the skin. Acupuncture may help reduce anxiety and depression.

Lifestyle and home remedies

As part of your recovery, you'll need to focus on changing your habits and making different lifestyle choices. These strategies may help:

Consider your social situation. Make it clear to your friends and family that you're not drinking alcohol. Develop a support system of friends and family who can support your recovery. You may need to distance yourself from friends and social situations that impair your recovery.
Develop healthy habits. For example, good sleep, regular physical activity, managing stress more effectively and eating well all can make it easier for you to recover from alcohol use disorder.
Do things that don't involve alcohol. You may find that many of your activities involve drinking. Replace them with hobbies or activities that are not centered around alcohol.

Coping and support

Many people with alcohol problems and their family members find that participating in support groups is an essential part of coping with the disease, preventing or dealing with relapses, and staying sober. Your health care provider or counselor can suggest a support group. These groups are also often listed on the web.

Here are a few examples:

Alcoholics Anonymous. Alcoholics Anonymous (AA) is a self-help group for people recovering from alcoholism. AA offers a sober peer group and is built around 12 steps as an effective model for achieving total abstinence.
Women for Sobriety. Women for Sobriety is a nonprofit organization offering a self-help group program for women who want to overcome alcoholism and other addictions. It focuses on developing coping skills related to emotional and spiritual growth, self-esteem, and a healthy lifestyle.
Al-Anon and Alateen. Al-Anon is designed for people who are affected by someone else's alcoholism. Alateen groups are available for teenage children of those with alcoholism. In sharing their stories, family members gain a greater understanding of how the disease affects the entire family.
Celebrate Recovery. Celebrate Recovery is a Christ-centered, 12-step recovery program for people struggling with addiction.
SMART Recovery. SMART Recovery offers mutual support meetings for people seeking science-based, self-empowered addiction recovery.

Preparing for an appointment

Here's some information to help you get ready for your appointment, and what to expect from your health care provider or mental health provider.
