The standard treatment for low blood sugar is to have the affected individual consume 15 grams of carbohydrates, according to MedlinePlus. After consuming the carbohydrates, the person should wait 15 minutes and then check his blood-glucose levels to see if another 15-gram dose of carbohydrates is needed.
Some common food and beverage options containing about 15 grams of carbohydrates each include 4 ounces of juice, 2 tablespoons of raisins, 8 ounces of nonfat milk, and 1 tablespoon of sugar or honey, reports the American Diabetes Association. Glucose tablets and gel tubes provide another way to get 15 grams of carbohydrates into the body quickly. Glucagon injections are available for people who frequently experience severe drops in blood sugar.
Hypoglycemia is the scientific name for low blood sugar, and it is typically caused by insufficient food intake or too much insulin in the body. According to the University of Michigan, hypoglycemia is most common in people with diabetes but can occur in individuals without the condition.
In hypoglycemia, the blood sugar level drops below 70 milligrams per deciliter, explains the University of Michigan. If the condition progresses without treatment, blood-glucose levels may continue to drop. If the level drops below 35 to 40 milligrams per deciliter, the person may have a seizure or go into a coma.
