802 PART 5 Medical Nutrition Therapy Treatment involves minimizing abdominal stress. Small, frequent meals may be better tolerated than three full meals a day; and these meals should be low in fiber and fat. If solid foods are not well tolerated, liquid meals may need to be recommended. As much as possible, the timing of insulin administration should be adjusted to match the usually de- layed nutrient absorption. Insulin injections may even be required after eating. Frequent blood glucose monitoring is important to determine appropriate insulin therapy. Hypoglycemia of nondiabetic origin has been defined as a clinical syndrome with diverse causes in which low levels of plasma glucose eventually lead to neuroglycopenia (Ser - vice, 1995). Hypoglycemia literally means low (hypo) blood glucose (glycemia). Normally the body is remarkably adept at maintaining fairly steady blood glucose levels -usually between 60 and 100 mg/dl(3.3 to 5.6 mmol%L), despite the intermittent ingestion of food. Maintaining normal levels of glucose is important because body cells, especially the brain and central nervous system, must have a steady and consistent supply of glucose to function properly. Under physiologic conditions the brain depends almost exclu - sively on glucose for its energy needs. Even with hunger, either because it is many hours since food was eaten or because the last meal was small, blood glucose levels re - main fairly consistent. Pathophysiology However, in a small number of people blood glucose levels become too low. Symptoms of hypoglycemia are often felt when blood glucose is below 65 mg/dl(3.6 mmoVL). If the brain and nervous system are deprived of the glucose they need to function, symptoms such as sweating, shaking, weakness, hunger, headaches, and irritability can develop. Hypoglycemia can be difficult to diagnose because these typical symptoms can be caused by many different health problems besides hypoglycemia. For example, adrenaline (epinephrine) released as a result of anxiety and stress can trigger the symptoms of hypoglycemia.
