Occur typically during childhood or puberty and average age at onset is 16. Increased level of glucose in the urine prevent water reabsorption and this increases urine volume (polyuria) Reactive hypoglycemia: occurs 2-4 hours after eating a meal, possibly due to over secretion of insulin. Fasting hypoglycemia: usually caused by pancreatic cancer, leads to overproduction of insulin. Mets is a cluster of conditions that occur together and increase risk for heart disease, stroke, and diabetes: obesity (bmi>30, high blood triglycerides, poor blood glucose regulation, hypertension (high blood pressure) Functions: provide energy (calories, storage of energy- as triglycerides, insulation, protection, transport fat-soluble vitamins, provides flavor and texture to foods.
