Abusing Alcohol: Signs of a Drinking Problem

What counts as abusing alcohol?

There is no single number that defines a drinking problem. Doctors look at both the amount and the effects.

How much is too much?

In the US, one standard drink contains about 14 grams of pure alcohol: 12 oz (355 ml) of regular beer, 5 oz (150 ml) of wine, or 1.5 oz (44 ml) of 80-proof spirits.

No amount of alcohol is risk-free. Pregnant people, those under 21, people taking interacting medicines and people with liver disease or a history of alcohol problems should not drink.

Signs of alcohol abuse

Doctors use 11 criteria from psychiatry's diagnostic manual. Having 2 to 3 in the past year suggests a mild alcohol use disorder, 4 to 5 moderate, and 6 or more severe. In plain terms, ask yourself whether in the past year you have:

1. ended up drinking more, or for longer, than you intended
2. wanted to cut down or stop but could not
3. spent a lot of time drinking, being sick or getting over hangovers
4. had strong cravings
5. failed to meet responsibilities at work, school or home because of drinking
6. kept drinking even though it caused trouble with family or friends
7. given up activities you enjoyed in order to drink
8. got into risky situations while drinking, such as driving or unsafe sex
9. kept drinking even though it made you depressed, anxious or caused memory blackouts
10. needed more alcohol to get the same effect (tolerance)
11. had withdrawal symptoms such as shakiness, sweating, nausea, trouble sleeping or anxiety as alcohol wore off

Signs others may notice

• hiding alcohol or drinking secretly
• smelling of alcohol at unusual times
• mood swings, irritability and defensiveness about drinking
• missing work, falling behind, money problems
• unexplained injuries or bruises
• red face, puffy eyes, tremor of the hands in the morning

Physical effects of drinking too much

• Liver: fatty liver, alcoholic hepatitis and cirrhosis (alcoholic liver disease)
• Heart and circulation: high blood pressure, irregular heartbeat (atrial fibrillation), weakened heart muscle
• Gut and pancreas: gastritis, reflux, pancreatitis
• Brain and nerves: memory problems, numbness and burning in the feet (alcoholic neuropathy), and in severe vitamin B1 deficiency, Wernicke-Korsakoff syndrome
• Cancer: higher risk of mouth, throat, esophagus, liver, breast and bowel cancer
• Mental health: worse depression, anxiety and insomnia
• Injuries: falls, road crashes, burns and violence

Who is at higher risk

• family history of alcohol problems
• starting to drink at a young age
• depression, anxiety, PTSD or ADHD
• trauma or high stress
• social settings where heavy drinking is normal

How doctors assess alcohol use

A primary care doctor will ask about how often and how much you drink, often using a short questionnaire such as the AUDIT-C. They may examine you and order blood tests for liver function, blood count, and vitamin levels. The aim is not to judge but to understand the risk and plan support.

How to cut down or stop safely

Practical steps

• Set a clear goal: a limit per day and per week, or not drinking at all.
• Keep a drinking diary for a few weeks.
• Plan alcohol-free days each week.
• Don't keep alcohol at home; alternate alcoholic drinks with water.
• Identify triggers, such as stress, certain people or times of day, and plan other responses.

Treatment options

• Talking therapies: cognitive behavioral therapy, motivational interviewing and couples or family therapy.
• Medicines: naltrexone, acamprosate and disulfiram are approved in the US to help people reduce drinking or stay sober. Your doctor will check which is safe for you.
• Mutual-help groups: Alcoholics Anonymous, SMART Recovery and others offer ongoing peer support.
• Residential or intensive outpatient programs for severe or complicated cases.

In the US, the SAMHSA National Helpline (1-800-662-4357) offers free, confidential treatment referral 24 hours a day.

Frequently asked questions

What are the signs that someone is abusing alcohol?

Common signs are drinking more or longer than intended, failed attempts to cut down, cravings, drinking despite problems at work or home, needing more to feel the same effect, and withdrawal symptoms such as shaking or sweating. Hiding alcohol and unexplained injuries are signs others may notice.

What is the difference between alcohol abuse and alcoholism?

Older terms separated "alcohol abuse" (harmful drinking) from "alcohol dependence" or alcoholism (physical dependence). Doctors now combine them into one diagnosis, alcohol use disorder, graded mild, moderate or severe according to how many criteria apply.

Is it dangerous to stop drinking suddenly?

It can be for people who drink heavily every day. Withdrawal can cause tremors, hallucinations and seizures, starting 6 to 24 hours after the last drink. Speak to a doctor before stopping. Supervised withdrawal with medication is safe and effective.

Can you recover from alcohol abuse?

Yes. Many people with alcohol use disorder recover fully or greatly reduce their drinking with treatment and support. Relapse is common and is a reason to adjust treatment, not to give up. The liver, heart and brain often improve after drinking stops.

How can I help someone who drinks too much?

Choose a calm, sober moment to talk. Describe specific concerns without blaming, and offer to help them find support. Look after yourself too, for example through Al-Anon. If they are in danger, such as with alcohol poisoning or suicidal thoughts, call emergency services.
