Alcohol has calories without the vitamins, minerals, and other nutrients that are essential for maintaining good health. A doctor can discuss whether it’s safe for an individual with diabetes to drink.
People who are trying to lose weight need to account for the calories in alcohol in diet planning. A dietitian also can provide information about the sugar and alcohol content of various alcoholic drinks.
Alcohol on an empty stomach can cause low blood glucose or hypoglycemia. Hypoglycemia is a particular risk in people who use oral medications or insulin for diabetes. It can cause shaking, dizziness, and collapse. People who don’t know someone has diabetes may mistake these symptoms for drunkenness and neglect to seek medical help.
Oral diabetes medications–tolbutamide and chlorpropamide–can cause dizziness, flushing, and nausea when combined with alcohol. A doctor can advise patients on the safety of drinking when taking these and other diabetes medications.
Frequent, heavy drinking can cause liver damage over time. Because the liver stores and releases glucose, blood glucose levels may be more difficult to control in a person with liver damage from alcohol.
Frequent heavy drinking also can raise the levels of fats in blood, increasing the risk of heart disease.
