In Children → those above + enuresis (bed-wetting), unusual fatigue & irritability ○ Type 1 → beta cells in pancreas are destroyed and produce no insulin i. Treatment → insulin injections, continuous infusion via pump & diet control ○ Type 2 → beta cells in pancreas secrete insulin, but the body is resistant to its effects i. Treatment → insulin, oral hypoglycemic injections & diet control ○ Diet Management → monitor total calories, carbs & timing of food ○ Diet Intake → meals with complex carbs, ↓ fat, ↑ fiber, some protein i. Time meals with peak effect of insulin ii. Provide extra snacks for unplanned physical activity iii. Substitute soft foods 6-8 times per day if you cannot stick with the usual meal plan iv. If vomiting, diarrhea or fever persist take in some liquids like ½ cup coke, juice, broth or 1 cup of gatorade to maintain caloric intake every ½ hour or hour v. Report nausea, vomiting & diarrhea to HCp → extreme fluid loss = dangerous vi. Unable to retain fluids = hospitalization to prevent DKA ○ Patient Teachings → lose weight if obese, oral hypoglycemic agents, maintain healthy weight, s/s of hypoglycemia & hyperglycemia, self-monitoring of glucose, skin/foot care, importance of exercise ○ “Sick Day” Rules → guidelines for managing diabetes when ill → aimed at preventing DKA i. Take insulin or hypoglycemic agents as usual ii. Test blood glucose & urine ketones every 3-4 hrs → report elevated levels to MD iii. If you take insulin, you may need supplemental doses every 3-4 hours ○ Dawn Phenomena → early morning glucose levels are elevated caused by nocturnal release of growth hormone ○ Somogyi Effect → fall in blood glucose during the night with ↑ morning glucose levels → caused by 5.
