Chronic Alcohol Use Disorder

What is Chronic Alcohol Use Disorder?

Chronic alcohol use disorder is a medical condition where someone has difficulty controlling their alcohol intake despite negative consequences. It affects how the brain responds to alcohol, making it harder to stop or reduce drinking even when it causes health problems, relationship issues, or work difficulties.

This condition exists on a spectrum from mild to severe. About 14.5 million adults in the United States have alcohol use disorder. It changes brain chemistry over time, particularly affecting areas that control judgment, decision-making, and impulse control. Chronic alcohol use can damage nearly every organ system in the body, including the liver, heart, brain, and digestive system.

Recovery is possible with the right support and treatment. Many people successfully reduce or stop drinking with medical care, counseling, and lifestyle changes. Regular monitoring through blood tests can track your body's healing process and provide motivation during recovery.

Symptoms

Drinking more or for longer periods than intended
Unsuccessful attempts to cut down or stop drinking
Spending significant time obtaining, using, or recovering from alcohol
Strong cravings or urges to drink
Failing to fulfill work, school, or home responsibilities due to drinking
Continuing to drink despite relationship problems
Giving up activities you once enjoyed to drink instead
Drinking in dangerous situations, such as before driving
Needing more alcohol to feel the same effects, known as tolerance
Experiencing withdrawal symptoms like shaking, sweating, nausea, or anxiety when not drinking

Some people function well at work or home while struggling with alcohol use disorder. This can make the condition harder to recognize in yourself or others.

Causes and risk factors

Chronic alcohol use disorder develops from a combination of genetic, psychological, and environmental factors. People with a family history of alcohol problems have a 50% higher risk of developing the condition themselves. Certain genes affect how your body processes alcohol and how your brain responds to its effects. Early alcohol use, especially before age 15, significantly increases later risk.

Mental health conditions like depression, anxiety, and trauma raise the risk of developing alcohol use disorder. Stress, peer pressure, and cultural attitudes about drinking also play important roles. Physical dependence develops as your brain adapts to regular alcohol exposure, changing neurotransmitter levels and creating a cycle that becomes harder to break without support.

How it's diagnosed

Healthcare providers diagnose chronic alcohol use disorder through detailed conversations about your drinking patterns, physical exams, and blood tests. They assess 11 specific criteria related to alcohol use and its consequences. Meeting 2 or 3 criteria indicates mild disorder, 4 or 5 indicates moderate, and 6 or more indicates severe disorder.

Blood tests help identify liver damage and other health effects from chronic drinking. Gamma-Glutamyl Transferase, or GGT, is a liver enzyme that rises in 70 to 80% of people with chronic alcohol use. Testing GGT levels helps track liver health and monitor recovery progress. Rite Aid offers GGT testing as part of our health panel, making it easy to monitor your health at any Quest Diagnostics location.

Frequently asked questions

Heavy drinking refers to consuming large amounts of alcohol regularly. Alcohol use disorder includes heavy drinking plus difficulty controlling alcohol use despite negative consequences. Someone with alcohol use disorder continues drinking even when it causes health problems, relationship issues, or interferes with daily responsibilities. The condition also involves physical dependence and withdrawal symptoms.

Chronic alcohol use damages the liver in stages, starting with fatty liver disease. Continued drinking can lead to alcoholic hepatitis, which causes liver inflammation and cell death. Without stopping alcohol use, this can progress to cirrhosis, where scar tissue replaces healthy liver tissue. GGT levels in your blood rise as the liver becomes stressed, even before serious damage occurs.

Yes, recovery is absolutely possible with appropriate treatment and support. Many people successfully reduce or stop drinking and rebuild their health. The brain and body have remarkable healing abilities when alcohol use stops. Regular medical care, counseling, support groups, and sometimes medication all improve recovery outcomes.

GGT levels typically begin dropping within days of stopping alcohol use. They often return to normal ranges within 4 to 8 weeks of abstinence. The exact timeline varies based on how high your levels were and how long you drank heavily. Regular testing every few months helps you see your progress and stay motivated during recovery.

Severe alcohol withdrawal can cause seizures, hallucinations, and delirium tremens, a life-threatening condition with confusion, rapid heartbeat, and high fever. These symptoms typically occur in people who have been drinking heavily for weeks, months, or years. Medical supervision during withdrawal is critical for safety. Never attempt to stop drinking suddenly without medical guidance if you have been drinking heavily.

No, not everyone who drinks heavily develops alcohol use disorder, though heavy drinking significantly increases the risk. Genetic factors, mental health, age of first use, and environment all influence who develops the condition. About 10% of people who drink alcohol will develop alcohol use disorder at some point in their lives.

Chronic alcohol use often causes deficiencies in thiamine, or vitamin B1, folate, vitamin B12, and magnesium. Alcohol interferes with nutrient absorption in the digestive system and increases nutrient loss. Thiamine deficiency is particularly serious and can cause permanent brain damage if untreated. Nutritional supplementation is an important part of recovery treatment.

Yes, several FDA-approved medications effectively reduce cravings and support recovery. Naltrexone blocks the rewarding effects of alcohol in the brain. Acamprosate helps restore brain chemistry balance disrupted by chronic drinking. Disulfiram causes unpleasant reactions when you drink, creating a deterrent. These medications work best when combined with counseling and support.

Testing every 3 to 6 months during the first year of recovery helps track liver healing and overall health improvements. Your healthcare provider may recommend more frequent testing if your liver enzymes were very high. Regular testing provides concrete evidence of your body's recovery and can increase motivation to maintain abstinence.

Relapse is common and does not mean failure or that you cannot recover. Contact your healthcare provider or counselor immediately for support. Return to treatment strategies that worked before and explore what triggered the relapse. Many people experience one or more relapses before achieving long-term recovery. The important thing is to get back on track as quickly as possible.
