Alcohol-use disorder describes drinking that has become difficult to control and is causing harm or dependence. It can affect physical health, mood, relationships, work and finances. Long-term heavy drinking increases the risk of liver disease, pancreatitis, high blood pressure, stroke, several cancers, malnutrition and problems with memory and mental health.
Dependence changes the nervous system. Someone who wakes shaky, sweaty, nauseated or anxious and needs alcohol to feel normal should not stop suddenly without medical advice. Severe withdrawal can cause confusion, hallucinations or seizures and requires emergency treatment.
Getting effective help
A GP or local alcohol service can assess drinking, physical health and withdrawal risk. Treatment may include a medically supported detoxification, cognitive behavioural therapy, mutual-aid support and medicines such as acamprosate or naltrexone to reduce cravings. Disulfiram is suitable for selected people who understand its interaction with alcohol.
Abstinence is usually advised for dependence, pregnancy, significant liver disease or when alcohol interacts with medication. Someone not ready to stop can still receive practical harm-reduction support. A daily drink record, alcohol-free alternatives and changing routines can help, but withdrawal symptoms always take priority over a self-directed reduction plan.
Nutrition should be addressed because heavy drinking can displace food and impair absorption. Regular meals containing protein, whole grains, vegetables, fruit and unsaturated fats support recovery. Thiamine deficiency can cause permanent neurological injury; clinicians commonly provide thiamine during withdrawal and early recovery when risk is present.
Useful supplements
Supplements should be selected for the individual rather than used automatically. Product directions and advice from an appropriately qualified professional should take precedence over general information.
| Supplement | Effects |
|---|---|
| High-quality multivitamin and mineral formula | Provides broad nutritional support for immune function, healing and correction of dietary shortfalls. |
| Evening primrose oil | Provides GLA and is described as helping reduce some symptoms experienced during alcohol withdrawal. |
| Krill oil or fish oil | Provides DHA and EPA, which support brain and cell-membrane function and tissue repair; the source describes a possible effect on cravings. |
| Zinc | Supports normal brain, immune, intestinal and liver-enzyme function and may be depleted with heavy alcohol use. |
| Vitamin C with bioflavonoids | Provides antioxidant support and contributes to normal stress-response and liver function. |
| Amino acids including glutamic acid, cysteine, glycine and glutathione | Supplies components used by the liver’s antioxidant and detoxification systems. |
| B-complex vitamins | Replaces vitamins commonly depleted by poor intake and chronic alcohol exposure. |
| Vitamin B5 | Supports normal energy metabolism and synthesis of stress-related hormones. |
Supplements cannot prevent withdrawal seizures, reverse cirrhosis or neutralise alcohol. The source zinc and vitamin C doses are high for unsupervised use, and glutathione products have variable evidence. Thiamine is the critical vitamin in dependent drinking, but its dose and route should be clinically determined.
Recovery is not a test of willpower. It is a treatable health condition, and combining medical care, psychological support, social stability and sound nutrition gives the strongest foundation for sustained change.
