What is the effect of alcohol on blood sugar levels?
People with diabetes should be cautious about drinking
alcohol. Too much alcohol can make blood sugar levels fall
too low. Drinking even a small amount of alcohol on an empty
stomach can lead to a very low blood sugar. If you take
insulin or diabetes pills, your blood glucose may go too low
when you drink because alcohol interferes with the effects
of the medicine. In addition, some medicines, including
those for diabetes, can interact with alcohol. This can be
serious and potentially life-threatening.
What are the other effects of drinking alcohol when you have diabetes?
Alcohol can make some diabetic health problems worse. If
there is nerve damage in the arms or legs, eye disease, high
blood pressure, liver disease, or other health problems
related to diabetes, drinking any amount of alcohol can make
these problems worse. Drinking heavily or for a long period
of time can cause nerve damage. If you have diabetic
neuropathy, drinking will make it worse.
People with diabetes are at risk for high blood pressure.
Alcohol has been shown to increase blood pressure. High
blood pressure can increase diabetic complications such as
kidney failure, retinopathy, and heart disease. Not drinking
alcohol can help lower high blood pressure.
Diabetics who have high levels of triglycerides in their
blood should not drink alcohol. Even light drinking (two
4-ounce glasses of wine a week) will raise triglyceride
levels.
What are the guidelines for drinking alcohol if I have diabetes?
People who have trouble controlling their diabetes or who
have complications should avoid drinking alcohol altogether.
If you drink alcohol, follow these tips:
- Never drink alcohol on an empty stomach. Have a meal or a snack (especially if you are going to bed after drinking
alcohol) and sip it slowly.
- Limit yourself to 1 drink if you are a woman and 2 drinks if you are a man. Men and women metabolize alcohol
differently. One drink equals one 12-ounce beer, one
5-ounce glass of wine, or one and one-half ounce shot of
spirits.
- Select drinks that are low in alcohol and sugar. For
example, light beer and dry wine are good choices. Use
diet soft drinks or water to mix drinks.
- Do not drink alcohol if you are trying to lose weight. It
is loaded with extra calories and lacks nutrients.
- If you cook with alcohol, use regular drinking wine, not
cooking wine. There is less sodium in the drinking wine.
Cook the food slowly so that the alcohol has time to burn
off.
- Always wear a diabetes alert bracelet. If you have a low
blood glucose reaction, you want others to know that you
have diabetes and are not drunk.
- Monitor your blood sugar often. Have a high-carbohydrate
snack handy, or glucose tablets or gel. Glucagon will not
help in the treatment of alcohol-induced hypoglycemia.
- Combining alcohol with exercise can cause the blood sugar
level to lower, even hours after the physical activity.
It is better to quench your thirst with water before,
during, and after exercise.
