Diabetes And Alcoholism

Quick Answer
Alcohol can make diabetes harder to manage. Beer, sweet wine, liqueurs and sugary mixers may raise glucose at first, while alcohol can later cause delayed hypoglycemia—especially in people using insulin, sulfonylureas or meglitinides. People who do not drink should not start for possible health benefits. Those who choose to drink should first ask whether it is safe for them, take it with food, monitor glucose and stay within recommended limits.

Hi Kirit,



Alcohol does not affect every person with diabetes in the same way. The effect depends on the amount and type of drink, food intake, diabetes medicines, activity, liver and kidney health, and the person’s usual glucose pattern.



Can Alcohol Raise or Lower Blood Sugar?



It can do both. Beer, sweet wine, cocktails, cider and liqueurs may contain enough carbohydrate to raise glucose soon after drinking. Spirits contain little carbohydrate by themselves, but juice, regular soda, syrup and other mixers can raise glucose.



Several hours later, alcohol may lower glucose because the liver gives priority to processing alcohol and may release less stored glucose. The risk is greater when drinking without food, after exercise, or while using insulin or medicines that stimulate insulin release.



See our detailed guide to alcohol and blood sugar.




Delayed lows matter: Hypoglycemia may occur during the night or many hours after the last drink. Symptoms such as confusion, sleepiness, slurred speech and poor coordination can be mistaken for intoxication.


Who Has the Greatest Risk of Hypoglycemia?




  • People using insulin

  • People taking sulfonylureas or meglitinides

  • Anyone drinking on an empty stomach

  • People who exercised more than usual

  • Those with kidney or liver disease

  • People with previous severe lows or hypoglycemia unawareness



Metformin alone does not usually cause hypoglycemia, but heavy alcohol use can still be unsafe and may interact with a person’s overall health and treatment plan.



How Much Alcohol Is Considered Moderate?



For adults who are medically able and choose to drink, common guidance limits intake to no more than one standard drink per day for women and no more than two for men. This is a maximum, not a recommendation to drink every day.




  • About 355 mL of 5% beer

  • About 150 mL of 12% wine

  • About 45 mL of 40% spirits



Large glasses, strong beer and generous spirit measures may contain more than one standard drink. People who do not drink should not begin drinking to lower glucose or protect the heart.



When Should Alcohol Be Avoided?



Alcohol may be unsafe or require strict limitation in people with:




  • pregnancy or plans for pregnancy;

  • recurrent hypoglycemia or inability to recognize lows;

  • liver disease, pancreatitis or very high triglycerides;

  • advanced neuropathy, kidney disease or unstable glucose;

  • medicines that interact with alcohol;

  • a history of alcohol use disorder or difficulty controlling intake;

  • a need to drive, operate machinery or perform safety-sensitive work.



Our guide to diabetes and liver health explains why liver disease changes the risk.



Safer Steps If Your Doctor Says You May Drink




  • Never drink on an empty stomach; have it with a meal containing carbohydrate.

  • Do not skip insulin or medicine to “make room” for alcohol.

  • Check glucose before drinking, later in the evening and before sleep when advised.

  • Use CGM alerts when available and keep fast-acting glucose nearby.

  • Tell a companion that you have diabetes and how to recognize a low.

  • Avoid sugary mixers and count carbohydrates in beer, wine and cocktails.

  • Do not use alcohol as a treatment for high glucose.



Review the symptoms and treatment steps in low blood glucose causes and treatment.




Emergency: If a person is unconscious, having a seizure, cannot swallow, is breathing abnormally or cannot be awakened, call emergency services. Do not assume the person is merely drunk.


What About Alcoholism?



The medical term is alcohol use disorder. It is a treatable health condition, not a moral failure. Warning signs include drinking more than intended, unsuccessful attempts to cut down, needing increasing amounts, withdrawal symptoms, or continuing despite harm to health, work or relationships.



A person who drinks heavily every day should not suddenly stop without medical advice because alcohol withdrawal can be dangerous or life-threatening. A doctor can arrange safe withdrawal management and evidence-based treatment.



Does Moderate Drinking Benefit Diabetes?



Some observational studies have associated moderate drinking with lower glucose or cardiovascular risk, but these findings do not prove that alcohol provides the benefit. Alcohol also adds calories, can raise triglycerides and blood pressure, impair judgment, interfere with medicines and increase the risk of several diseases.



There is no medical need to start drinking. Glucose, heart and liver health can be improved more safely through nutrition, activity, weight management, sleep, smoking cessation and appropriate medication.



My Advice



If you have diabetes and drink alcohol, tell your healthcare professional honestly how much and how often. Ask whether your medicines can cause hypoglycemia and whether alcohol is safe with your liver, kidneys, triglycerides and other conditions.



If drinking is difficult to control, seek medical support rather than trying to manage it alone. Effective treatment is available.



Hope this helps.
