Type 2: non-insulin-dependent diabetes mellitus Symptoms Gestational diabetes: diabetes in Glycosuria: glucose in the urine pregnancy Polyuria: excessive urination Polydipsia: excessive thirst Prediabetes Polyphagia: excessive appetite Improper use of insulin by the cells Loss of weight, weakness, and of the body fatigue Fasting blood glucose > 110 mg/dL but < 126 mg/dL Complications May advance to type 2 diabetes Ketones: substances into which fatty acids are broken down in the Type 1 Diabetes liver Formerly juvenile-onset diabetes Ketoacidosis: condition in which mellitus acids from ketones accumulate. 5%-10% of all new diabetes cases Little, if any, insulin is secreted.

High fiber may mean 25-35 g of Insulin Therapy dietary fiber a day.

Insulin must be injected because it Alternative Sweeteners is a protein and would be digested Saccharin has been shown to if swallowed produce bladder cancer in rats Human insulin is the most common when used in large quantities. and the preferred insulin; it is made Approved by the FDA synthetically.

Dietetic foods often contain the Insulin pumps are now available same ingredients as foods and can deliver short-acting prepared for the general public, but continuous dose and premeal at a higher cost. boluses. Consumers need to read the food labels. Insulin Reactions An insulin reaction, or Alcohol hypoglycemic episode, can result Not recommended for diabetic from too much insulin. clients Symptoms include headache, Limited use sometimes allowed if blurred vision, tremors, confusion, approved by a physician poor coordination, and eventually Some diabetic clients who use unconsciousness. hypoglycemic agents cannot Brain damage, coma, or death can tolerate alcohol. result. Include in diet plan if used Treatment for Insulin Reactions Conscious clients may be treated by giving them a glucose tablet, a sugar cube, or a beverage containing sugar followed by a complex carbohydrate. Unconscious clients require intravenous treatment with dextrose and water. Diabetic clients should carry identification. Considerations for the Health Care Professional If diet is followed, medication is taken, and time is allowed for sufficient exercise and rest, one can live a near-normal life. Emphasize the importance of eating all of the prescribed food. Meals should be eaten at regular times, and clients should read labels. Summary The diabetic diet is used in treating diabetes mellitus, a metabolic disease caused by the improper functioning of the pancreas. Serious complications, including death, can occur if the condition is left untreated. Treatment includes diet, medication, and exercise.

Because of the nausea and diarrhea, sufficient fluids are essential. Tube feeding may be necessary if client has difficulty swallowing or simply cannot eat. Summary Surgery, burns, fevers, and infections are traumas that cause the body to respond ina hypermetabolic manner. This response creates the need for additional nutrients at the same time that the injury causes a loss of nutrients. Nutritional Care of Clients Nutritional Care Fever, nausea, fear, depression, chemotherapy, and radiation can destroy one's appetite. Vomiting, diarrhea, chemotherapy, radiation, and some medications Offer bedpan and hygiene care can reduce or prevent absorption before and after the meal. of nutrients.

PEM is a major problem for this population. Anemia can develop and contribute to fatigue, confusion, and depression. Sufficient animal protein and vitamin C should be provided in the diet. Pressure ulcers (bedsores) can develop in bedridden clients and must be prevented. Healing of pressure ulcers requires treatment of the ulcer, relief of the pressure, a high-calorie diet with sufficient protein, vitamin C, and zinc supplements. Constipation can be caused by inadequate fiber, fluid, or exercise. Other causes include medication, reduced peristalsis, or former abuse of laxatives. Treatment includes increasing fluid, fiber, and exercise. The sense of smell declines with age and the appetite diminishes. Xerostomia (dry mouth) can be caused by disease or medications. Drinking water, eating frequent, small meals, and chewing sugar-free gums or candies may be helpful. Summary Illness and surgery can have devastating effects on a client's nutritional status. PEM can be a significant problem in hospitals.
