General Considerations in Treatment of Diabetes

Insulin-treated patients with diabetes can have a full and satisfying life. However, "free" diets and unrestricted activity are still not advised. Until new methods of insulin replacement are developed that provide more normal patterns of insulin delivery in response to metabolic demands, multiple feedings with carbohydrate counting will continue to be recommended, and certain occupations potentially hazardous to the patient or others will continue to be prohibited because of risks due to hypoglycemia. The American Diabetic Association can act as a patient advocate in case of employment questions.

Exercise increases the effectiveness of insulin, and moderate exercise is an excellent means of improving utilization of fat and carbohydrate in diabetic patients. A judicious balance of the size and frequency of meals with moderate regular exercise can often stabilize the insulin dosage in diabetics who tend to slip out of control easily. Strenuous exercise can precipitate hypoglycemia in an unprepared patient, and diabetics must therefore be taught to reduce their insulin dosage in anticipation of strenuous activity or to take supplemental carbohydrate. Injection of insulin into a site farthest away from the muscles most involved in exercise may help ameliorate exercise-induced hypoglycemia, since insulin injected in the proximity of exercising muscle may be more rapidly mobilized.

All diabetic patients must receive adequate instruction on personal hygiene, especially with regard to care of the feet, skin, and teeth. All infections (especially pyogenic ones) provoke the release of high levels of insulin antagonists such as catecholamines or glucagon and thus bring about a marked increase in insulin requirements. Supplemental regular insulin is often required to correct hyperglycemia during infection.
