Causes and Risk Factors
Alcohol use disorder develops from a combination of genetic, psychological, and social influences:- Family history: Genetics account for a significant share of risk; having a parent or sibling with an alcohol problem raises your own risk.
- Starting young: People who begin drinking heavily in their teens are more likely to develop problem drinking as adults.
- Mental health conditions: Depression, anxiety, post-traumatic stress, and chronic sleep problems often occur alongside alcohol use disorder, and each can worsen the other.
- Heavy drinking patterns: Regular binge drinking — four or more drinks on one occasion for women, five or more for men — builds tolerance and trains the brain to expect alcohol.
Signs and Symptoms
Doctors consider the diagnosis when several of the following occur within the same year:- Loss of control: Drinking more, or for longer, than intended, or wanting to cut down and being unable to.
- Craving: A strong urge or need to drink.
- Tolerance: Needing more alcohol to feel the same effect.
- Withdrawal: Shakiness, sweating, nausea, anxiety, or trouble sleeping when alcohol wears off.
- Continued use despite consequences: Drinking that persists even after it causes problems with health, relationships, work, or safety.
Health Effects
Over time, heavy drinking can damage nearly every organ system:- Liver disease: Alcohol is a leading cause of fatty liver disease, alcoholic hepatitis, and cirrhosis.
- Heart and blood vessels: Heavy use raises blood pressure, weakens the heart muscle, and can trigger rhythm problems such as atrial fibrillation.
- Cancer risk: Alcohol increases the risk of cancers of the mouth, throat, esophagus, liver, colon, and breast.
- Brain and nerves: Long-term use contributes to memory problems, nerve damage, and worsening mood and sleep.
Diagnosis
Diagnosis starts with an honest, confidential conversation. Your physician may use brief screening questionnaires, review your drinking pattern and medical history, examine you, and order blood tests — including liver enzymes — to look for early organ effects. There is no judgment in this process; the goal is simply an accurate picture of your health.Treatment
Treatment is tailored to your goals, whether that is cutting back or stopping entirely:- Medications: Naltrexone reduces craving and the rewarding effect of alcohol; acamprosate helps maintain abstinence after stopping; disulfiram discourages drinking by causing an unpleasant reaction if alcohol is consumed.
- Counseling: Cognitive behavioral therapy and motivational approaches build practical skills for changing drinking habits.
- Support groups: Mutual-support programs add accountability and community.
- Medically supervised withdrawal: Long-term heavy drinkers should not stop abruptly on their own — withdrawal can be dangerous and may require monitored treatment.
When to Seek Immediate Care
Severe withdrawal — confusion, hallucinations, fever, a racing heart, or seizures — can signal delirium tremens, a medical emergency. Call 911 or go to the nearest emergency department. If drinking has become hard to control, you are not alone and effective help exists.

Alcohol use disorder is a medical condition with effective treatments, and it is among the most undertreated conditions in medicine — a small fraction of people who meet criteria receive any evidence-based treatment at all. Much of that gap comes from a persistent assumption that treatment means abstinence-based programmes and nothing else.
Medication is effective and rarely offered
Naltrexone reduces heavy drinking days and craving and can be taken while still drinking, which makes it usable by people not ready to stop entirely. Acamprosate supports maintenance of abstinence and is safe in liver disease. Disulfiram works through deterrence and suits a specific, motivated group. These are prescribed to a small minority of eligible patients despite good evidence.
Reduction counts as success
Abstinence is not the only legitimate goal, and treating it as the sole measure deters people who would benefit from reducing. Cutting heavy drinking days substantially improves blood pressure, liver enzymes, sleep, and mood, and reduction frequently becomes a route to abstinence for people who would not have started with that target.
Withdrawal can be dangerous
Stopping abruptly after sustained heavy drinking can cause seizures and delirium tremens, which is potentially fatal. This is a genuine medical emergency and the reason people with significant physical dependence should not simply stop on their own. Medically supervised withdrawal is straightforward and available, and it is worth asking about rather than attempting alone.
Screening finds people who do not identify a problem
Brief screening tools identify risky drinking in people who would never raise it themselves, and brief intervention in primary care has good evidence. Alcohol contributes to high blood pressure, fatty liver, atrial fibrillation, and several cancers, so the conversation belongs in ordinary medical care. Our behavioural health team manages treatment. The NIAAA and SAMHSA national helpline provide confidential resources.
What recovery support actually looks like
Medication works better alongside some form of behavioural support, and the options are broader than the one most people picture. Cognitive behavioural approaches, motivational interviewing, structured outpatient programmes, and mutual-help groups all have a place, and different things suit different people. Choosing an approach you will actually attend matters more than choosing the one with the strongest average evidence.
If you are wondering whether your drinking is a problem, that question is itself worth bringing to a visit — schedule one.
