What Those with Diabetes Should Know about Drinking Alcohol

One of the most common questions among those with diabetes is whether they can drink alcohol. The real answer is more complicated than people might expect, so it is ‘it depends.’

There are many health reasons why people should avoid alcohol, some of them linked to diabetes and others to different health complications. That’s why it’s best to consult our healthcare provider if we have any doubts or concerns.

Even though we might have a hard time finding a health organization that recommends drinking alcohol, some agree moderate alcohol consumption is not-off limits to some people.

They include the American Cancer Society, the American Heart Organization, and the American Diabetes Association.

However, what’s the concern with diabetes and alcohol? Why and when some of these people should avoid it?

Here are a few facts that will help people understand if those with diabetes should avoid alcohol.

Things to Know about Alcohol and Diabetes

1. Alcohol Prevents the Liver from Doing Its Job

When we drink alcohol, our liver sees it as a drug, so it prepares to eliminate this poison. For that purpose, it has to break it down into less harmful substances which takes about 2 hours.

However, the liver performs many other functions in the body, including glucose released when the levels of blood glucose are starting to drop.

But, when alcohol enters our body, it becomes its number one priority, leaving its other functions behind. This means that if our blood sugar levels start decreasing, our liver won’t be able to see that and release the needed glucose.

This could end up in hypoglycemia, or low blood sugar which is dangerous for those with diabetes. It can lead to clumsiness, unconsciousness, and even death.

2. It Interacts with Our Diabetes Medication

Taking our diabetes medication doesn’t mean WE are less likely to experience hypoglycemia when drinking alcohol.  Taking some diabetes medication like meglitinides, sulfonylureas, chlorpropamide, tolazamide, insulin, glyburide, glimepiride, or nateglinide increases our risk of low blood sugar.

That’s because these medications stimulate insulin secretion in the pancreas, thus reducing blood sugar levels. So, combining alcohol with some of these medications is not the best idea for those with diabetes.

3. Don’t Drink Alcohol on an Empty Stomach

If we plan to drink alcohol, make sure to eat some snack or meal which contains carbohydrates before or during alcohol consumption. Foods with carbohydrates slow down the absorption of alcohol in the bloodstream.

4. A Glass of Alcohol as Part of the Evening Meal

According to an Israeli study, those with type 2 diabetes can drink a glass of alcohol as part of their dinner. The study showed that drinking alcohol in this way can lower blood sugar levels after a meal.

However, the dinner should include some food with carbohydrates, and 100 calories less to avoid weight gain.

5. Don’t Drink Right After a Workout

Exercise lowers our blood sugar levels, so if we grab a beer or wine right after running or skiing, we can further reduce our blood sugar. This could lead to hyperglycemia.

6. The Alcohol Metabolism Rate Is Individual

Overall, the effect of alcohol on our blood glucose level depends on our alcohol metabolism rate, which is individual. It depends on our body size, the amount and time of consumption, level of physical activity, as well as the amount and type of food consumed along with alcohol.

Other Risks of Drinking Alcohol

Some people should avoid alcohol as much as possible. They include pregnant women, those with uncontrolled diabetes, those with pancreatic or liver disease, and those with a history of alcoholism.

What’s more, we should know that alcohol increases the risk for the following problems:

  • Hypoglycemia
  • Pancreatitis
  • Cancer
  • Cardiomyopathy (weak heart muscle)
  • High blood pressure
  • Cirrhosis
  • Fetal alcohol syndrome
  • Miscarriage
  • Accidents

Possible Benefits of Drinking Alcohol

Web MD believes alcohol might help:

  • Reduce the risk of type 2 diabetes
  • Increase levels of good cholesterol
  • Reduce the risk of heart disease
  • Prevent the formation of gallstones
  • Lower the risk of stroke

Recommended Alcohol Guidelines

Women with diabetes can have 2 units of alcohol a day, whereas men can have 3. But, sometimes a pint of beer can constitute 3 units, and a glass of wine can reach 2 units.

One alcohol unit equals half a pint of standard strength beer, 50ml of vermouth or sherry, and 25ml of vodka, gin, or whiskey.


Those with diabetes should have several things in mind when drinking alcohol. But, this doesn’t mean that they can’t drink moderate amounts, especially red wine.
