How will alcohol affect you when you have diabetes?

“Alcohol can interfere with your meal plan and blood glucose control, especially if you’re taking insulin or medication for your diabetes,” says Ms Kala Adaikan, Senior Principal Dietitian, at the Department of Dietetics​, Singapore General Hosp​ital (SGH), a member of the SingHealth​ group.​

If you must drink, limit yourself to:

  1. One drink or one unit of alcohol a day (for women)
  2. Two drinks or two units of alcohol a day (for men)

One unit of alcohol is defined as any drink that provides 10g of alcohol.

This translates to:

  • 100ml of wine,
  • 30ml of spirits (about 1 shot glass) or
  • 220ml of beer (about two-thirds of a can).

If you have sub-obtimally controlled diabetes, try to abstain from alcohol. It is important to note that alcohol consumption can increase your risk of hypoglycaemia (low blood glucose levels). This is dangerous particularly when coupled with some diabetes medications. Consult your doctor or dietitian before ​consuming alcohol.
