Alcohol and Diabetes

Alcohol reduces blood sugar

Alcohol can make certain diabetes complications worse. It is important to note that consuming alcohol on an empty stomach may lead to low blood glucose levels or hypoglycemia, especially posing a risk for individuals on oral medications or insulin. Drinking reduces the liver's ability to regulate blood sugar and may interfere with certain diabetes medications. Women metabolize alcohol slower than men do.

Never drink on an empty stomach

Always eat prior to drinking an alcoholic beverage. If you rely on carbohydrate counting for meal planning, understand and consider how the type and amount of drinks you select will impact your blood glucose levels. Adjusting your insulin dosage may be necessary if you plan to have multiple beverages.

One drink =

  • 12 oz. of beer 
  • 5 oz. of wine
  • 1.5 oz. of hard liquor

Carbohydrates per serving

  • Craft beer sometimes contains twice the alcohol content and calorie count compared to light beer.
  • Choose diet soda, seltzer or sparkling water rather than high-calorie mixers to reduce calorie consumption.
