Explain the role of the hormones insulin and glucagon in the regulation of blood glucose
|
1. (When blood glucose rises (hyperglycemia)- like after a meal)
- Insulin (from the pancreas, targets liver, muscle, adipose tissue)--> glucose is cleared from the blood and glycogen is created. 2. (When blood glucose falls (hypoglycemia) like after exercising) - Gluagon (from pancreas, targets liver-->Glycogen breakdown=increased blood glucose in blood stream-->Hyperglycemia. Glucagon increases blood glucose level |
|
What is the normal range of blood glucose in humans?
|
70-100mg/dL
- liver is responsible for maintaining this |
|
Describe diabetes mellitus type 1
|
Autoimmune attack on the pancreas. Complete failure of blood glucose regulations. Autoimmun reaction occurs-->attacks beta cells in pancreas that make insulin-->pancreas looses ability to produce insulin=results in elevated levels of blood glucose. Insulin must be injected for life. Strong genetic predisposition. Insulin producing cells in pancreas are destroyed
|
|
Describe diabetes mellitus type 2
|
Progressive disease. Characterized by insulin resistance. Insulin production is not inhibited, but ability for body to respond to insulin is affected-->eventually amount of insulin produced from pancreas leads to high blood glucose. Insluin production may be low, normal, or high
|
|
What are the diet management approaches to diabetes type 1?
|
- Insulin injections.
- Diet must be coordinated with insulin-must regulate intake of carbohydrates. - Exchange system/Carbohydrate counting (through diabetic exchange system) - regular meals and 1 or more snacks as well as a well regulation of CHO:Protein:Fat to maximize swings in blood glucose - Diet should include ample fiber -Supply energy in balance with expenditure - Low in sat. fats and cholesterol |
|
hat are the diet management approaches to diabetes type 2?
|
Weight loss can reduce risk or help manage
|
|
What are the complications of diabetes? (7)
|
1. Leading cuase of kidney disease (nephropathy)
2. 60-70% of diabetics have mild to severe nerve damage (neuropathy)= diabetes is leaing cause of amputations, can affect bladder control 3. Leading cause of blindness-glucose can affect capillaries in eye 4. Hypertension in 60-70% of diabetics 5. 2-4X risk of stroke, 6. faster age decline in cognition 7. 2-4X risk of heart disease. Usually the cause of death with people with diabetes. |
