The blood glucose can be raised to normal within minutes by taking (or receiving) 10-20 grams of carbohydrate. It can be taken as food or drink if the person is conscious and able to swallow. . Hypoglycemia is relatively common in diabetics. It occurs when too much insulin or oral antidiabetic medication is taken, not enough food is eaten, or from a sudden increase in the amount of exercise without an increase in food intake.. In certain cases, some persons suffer from Reactive hypoglycemia. They suffer from hypoglycemia immediately after taking food.. This amount of carbohydrate is contained in about 3-4 ounces (100-120 ml) of orange, apple, or grape juice, about 4-5 ounces (120-150 ml) of regular (non-diet) soda), about one slice of bread, about 4 crackers, or about 1 serving of most starchy foods. Starch is quickly digested to glucose, but adding fat or protein retards digestion. Symptoms should begin to improve within 5 minutes, though full recovery may take 10-20 minutes. Overfeeding does not speed recovery and if the person has diabetes will simply produce hyperglycemia afterwards.. Hypoglycemia unrelated to exogenous insulin therapy is an uncommon clinical syndrome characterized by low plasma glucose level, symptomatic sympathetic nervous system stimulation, and CNS dysfunction. Many drugs and disorders cause it. Diagnosis requires blood tests performed at the time of symptoms or during a 72-h fast. Treatment is provision of glucose combined with treatment of the underlying cause. . Please see the web pages for more details on Hypoglycemia.
