Low blood sugar, also called hypoglycemia, occurs when the amount of glucose in the blood drops below normal levels. If the level falls below 70 milligrams per deciliter, a food high in sugar should be consumed immediately. Symptoms of a low blood sugar episode include hunger, shakiness, sweating, dizziness or light-headedness and weakness. If untreated, symptoms may worsen to include confusion and fainting. Seek medical attention if low blood sugar is not alleviated by eating one of these sugar sources.
Beverages
Beverages containing sugar are absorbed quickly and are usually widely available. A serving of 4 oz. of fruit juice or soda is a good source of sugar for individuals with low blood sugar. Sodas should be the regular version, rather than the diet version. Another alternative is to drink 8 oz. of milk.
Carbohydrates
The American Diabetes Association recommends that you respond to an episode of low blood sugar by consuming 15 to 20 grams of sugars or carbohydrates. For packaged foods, you can check the nutrition information label to determine the amount that will provide at least 15 grams of carbohydrates. For example, four or five crackers or 2 tablespoons of raisins will be sufficient. Small, snack-size packages of these foods are convenient to carry in your car or purse. Foods that are also high in fat, such as a chocolate bar or cookies, will be less effective at treating low blood sugar quickly and are not the best option during a hypoglycemic episode.
Other Sugar Sources
Some individuals with a history of low blood sugar prefer to carry glucose tablets. Available from drugstores, these tablets are a convenient, pre-measured source of sugar that get absorbed rapidly into the bloodstream. 4 tsp. of sugar or 1 tbsp. of honey or corn syrup will have a similar effect. These foods are good sources to keep in mind when you are traveling or anytime you may not have access to reliable nutrition information labels.
