Foods with 15 to 20 grams of carbohydrates can increase and stabilize blood sugar when the sugar level in the blood falls too low, according to the American Diabetes Association. Examples of foods that increase blood sugar include 2 tablespoons of raisins and 4 ounces of juice or non-diet soda.
Other helpful foods for an incidence of low blood sugar are 1 tablespoon of sugar, honey or corn syrup and 8 ounces of nonfat or 1 percent milk, explains the American Diabetes Association. Hard candies, jelly beans and gumdrops also raise blood sugar. The individual should recheck blood sugar after consuming the suggested carbohydrates and should consume more carbohydrates if it is still too low. Glucose tablets and gel tubes are also available to treat low blood sugar. Once blood sugar has stabilized, the individual should eat a small snack or meal if the next meal is more than an hour away.
When blood sugar drops too much, hypoglycemia occurs, warns the American Diabetes Association. Hypoglycemia symptoms include shakiness, confusion, blurred vision, weakness and headaches. Untreated hypoglycemia is a dangerous condition that may lead to seizure or coma. Diabetics can obtain glucagon kits from their physicians to treat low blood sugar. Their family members and friends should know how to give it to the diabetic if it is needed.
