Diabetes and alcoholAlcohol - diabetes; Diabetes - alcohol use
If you have diabetes you may wonder if it's safe to drink alcohol. While many people with diabetes can drink alcohol in moderation, it's important to understand the possible risks of alcohol use and what you can do to lower them. Alcohol can interfere with how the body uses blood sugar (glucose). Alcohol can also interfere with certain diabetes medicines. You should also talk with your health care provider to see if it is safe for you to drink.
Diabetes and the Risks of Drinking Alcohol
For people with diabetes, drinking alcohol can cause low or high blood sugar, affect diabetes medicines, and cause other possible problems.
Diabetes is a long-term (chronic) disease in which the body cannot regulate the amount of sugar in the blood.Read Article Now Book Mark Article
LOW BLOOD SUGAR
Your liver releases glucose into the blood stream as needed to help keep blood sugar at normal levels. When you drink alcohol, your liver needs to break down the alcohol. While your liver is processing alcohol, it stops releasing glucose. As a result, your blood sugar level can drop quickly, putting you at risk for low blood sugar (hypoglycemia). If you take insulin or certain types of diabetes medicine, it can cause seriously low blood sugar. Drinking without eating food at the same time also greatly increases this risk.
Low blood sugar (hypoglycemia)
Low blood sugar is a condition that occurs when the body's blood sugar (glucose) decreases and is too low. Blood sugar below 70 mg/dL (3. 9 mmol/L) i...Read Article Now Book Mark Article
The risk for low blood sugar remains for hours after you take your last drink. The more drinks you have at one time, the higher your risk. This is why you should only drink alcohol with food and drink only in moderation.
ALCOHOL AND DIABETES MEDICINES
Some people who take oral diabetes medicines should talk with their provider to see if it is safe to drink alcohol. Alcohol can interfere with the effects of some diabetes medicines, putting you at risk for low blood sugar or high blood sugar (hyperglycemia), depending on how much you drink and what medicine you take.
High blood sugar (hyperglycemia)

OTHER RISKS FOR PEOPLE WITH DIABETES
Drinking alcohol carries the same health risks for people with diabetes as it does in otherwise healthy people. But there are certain risks related to having diabetes that are important to know.
Beer, wine, and liquor all contain alcohol. Drinking an excessive amount of alcohol can put you at risk for alcohol-related problems.Read Article Now Book Mark Article
- Alcoholic drinks such as beer and sweetened mixed drinks are high in carbohydrates, which can raise blood sugar levels.
- Alcohol has a lot of calories, which can lead to weight gain. This makes it harder to manage diabetes.
- Calories from alcohol are stored in the liver as fat. Liver fat makes liver cells more insulin resistant and can make your blood sugars higher over time.
- Symptoms of low blood sugar are very similar to symptoms of alcohol intoxication. If you pass out, those around you may just think you are intoxicated.
- Being intoxicated makes it harder to recognize the symptoms of low blood sugar and increases the risk.
- If you have diabetes complications, such as nerve, eye, or kidney damage, your provider may recommend that you not drink any alcohol. Doing so may worsen these complications.
Nerve damage that occurs in people with diabetes is called diabetic neuropathy. This condition is a complication of diabetes.Read Article Now Book Mark Article

How Much Alcohol is Safe?
To drink alcohol safely, you should be sure of the following:
- Your diabetes is in good control.
- You understand how alcohol may affect you and what steps to take to prevent problems.
- Your health care provider agrees that it is safe.
Anyone who chooses to drink should do so in moderation:
- Women should no more than 1 drink per day.
- Men should no more than 2 drinks per day.
One drink is defined as:
- 12 ounces or 360 milliliters (mL) of beer (5% alcohol content).
- 5 ounces or 150 mL of wine (12% alcohol content).
- 1.5-ounce or 45-mL shot of liquor (80 proof, or 40% alcohol content).
Talk to your provider about how much alcohol is safe for you.
Things to Keep in Mind If You Choose to Drink
If you decide to drink alcohol, taking these steps can help keep you safe.
- Do not drink alcohol on an empty stomach or when your blood glucose is low. Any time you drink alcohol, there is a risk of low blood sugar. Drink alcohol with a meal or with a carbohydrate-rich snack to maintain normal blood sugar levels.
- Never skip meals or have alcohol in place of a meal.
- Drink slowly. If you consume liquor, mix it with water, club soda, diet tonic water, or diet soda.
- Carry a source of sugar, such as glucose tablets, in case of low blood sugar.
- If you count carbohydrates as part of your meal plan, talk with your provider about how to account for alcohol.
- Do not exercise if you have been drinking alcohol, as it increases the risk for low blood sugar.
- Carry visible medical ID stating that you have diabetes. This is important because the symptoms of too much alcohol and low blood sugar are similar.
- Avoid drinking alone. Drink with someone who knows that you have diabetes. The person should know what to do if you start having symptoms of low blood sugar.
Because alcohol puts you at risk for low blood sugar even hours after you drink, you should check your blood glucose:
- Before you start drinking
- While you are drinking
- A few hours after drinking
- Up to the next 24 hours
Make sure your blood glucose is at a safe level before you go to sleep.
When to Call the Doctor

- Double vision or blurry vision
- Fast or pounding heartbeat
- Feeling cranky or acting aggressive
- Feeling nervous
- Shaking or trembling
- Tingling or numbness of the skin
- Tiredness or weakness
