Signs and Symptoms of Diabetes (all types)

- 3 P's: polydipsia (excessive thirst), polyuria (excessive urination), polyphagia (excessive hunger) -Hyperglycemia -Weight loss -Blurred vision -Slow wound healing -Vaginal infections -Weakness and paresthesia -Signs of inadequate circulation to the feet -Signs of accelerated atherosclerosis: renal, cerebral, cardiac, peripheral -Glycosuria (renal tubules cannot reabsorb extra glucose filtered by glomeruli) -Nocturia (nighttime urination)

Simple Carbohydrates to treat hypoglycemia 15-20 gram fast-acting

Non-Urgent Signs and Symptoms of Hyperglycemia

-Blurred vision -Headache -Fatigue -Increase thirst -Urinary frequency

Complications of Insulin Therapy: Dawn Phenomenon

-Characterized by hyperglycemia upon morning awakening that results from excessive early morning release of GH and cortisol -Treatment requires increase in patient's insulin dose or change in the time of insulin administration

Hypoglycemia Moderate Symptoms

DM leads to chronic health problems and early death: Macrovascular Complications

-Coronary artery disease {poor circulation} -Cardiomyopathy -HTN -Cerebrovascular disease -Peripheral vascular disease -Inflammation and hyperosmolarity in vessels

Diet in Diabetes

-Day to day consistency in timing and amount of food intake helps control the blood glucose level -DASH diet -Carb counting

Diabetes Mellitus (DM)

-Metabolic disorder in pancreas -Impaired carbohydrate, protein, lipid metabolism -Deficiency of insulin -Glucose can enter the cells only with help of insulin

Complications of Insulin Therapy: Somogyi Phenomenon

-Normal or elevated blood glycose levels are present at bedtime -Hypoglycemia occurs about 2:00 am to 3:00 am, which causes increase in the production of counterregulatory hormones -By 7:00 am in response to the counterregulatory hormones, the blood glucose rebounds significantly to the hyperglycemic range -Treatment includes: decreasing the evening (predinner/bedtime) dose of intermediate acting insulin, increase bedtime snack or both -Clients experiencing may complain of early morning headaches, night sweats, nightmares caused by morning hypoglycemia

Hypoglycemia

-Occurs when blood glucose levels fall below 70 mg/dL or drops rapidly from an elevated level -Caused by too much insulin or oral hypoglycemic agents, too little food, excessive activity
