Question | Answer |
Diabetes Mellitus | metabolic disorder of the pancreas affecting carbohydrate, fat, and protein metabolism |
Diabetes Mellitus is..... | metabolic disorder
chronic disorder
endocrine disorder
autoimmune disorder |
insulin | secreted by the beta islet cells,
lowers blood glucose levels |
glucagon | secreted by the alpha islet cells,
raises blood glucose levels (70-110) |
somatostatin | secreted by the delta islet cells,
inhibits release of both insulin and glucagon |
pancreatic polypeptide | controls exocrine secretion |
Type 1 diabetes mellitus | accounts for approximately 10%
pancreas produced NO INSULIN
usually during the childhood years
onset is rapid-over a period of weeks or months
people MUST INJECT INSULIN SEVERAL TIMES PER DAY OR CONTINUALLY INFUSE INSULIN THROUGH A PUMP |
Functions of Insulin | 1. carries glucose into cells as their preferred source of energy
2. it promotes the liver's storage of glucose as glycogen
3. it inhibits the breakdown of glycogen back into glucose |
INSULIN | without insulin the blood glucose level rises
the body breaks down fat and protein for alternative sources of cellular energy
glucose cannot enter the cell bc the insulin hasn't "unlocked" the key |
Type II Diabetes Mellitus | insulin resistance or insufficient insulin producion/ more common in aging adults/ younger people are being diagnose, especially obese children/treated with diet and exercise/80% are obese and weight loss often corrects the imbalance/if not, medications a |
Hyperglycemia | the blood sugar is going up because the body begins to break down stored fat and converting it to glucose
when fat is metabolized, ketones are released and excreted in the urine as acetone |
ketones | product of fat metabolism |
