Role of insulin:

-decrease blood glucose levels

role of glucagon:

-increase blood glucose levels

patho of insulin:

-insulin is produced by beta cells in the islets of pancreas

-blood glucose rises when a person eats

-insulin secretion increases and moves glucose into muscles, liver and fat
cells to transport and metabolize glucose for energy

path of glucagon:

-glucagon is secreted by the alpha cells and is released when blood glucose
levels decrease

-stimulates liver to release stored glucose

-liver produces glucose through breakdown of glycogen

diabetes:

-characterized by hyperglycemia

,-disorder of carb, fat, and protein metabolism

glucose regulation:

-maintaining optimal blood glucose levels

diabetes can result from:

-abnormal insulin secretion by the pancreas

-impairment in the body's ability to use insulin

-impaired liver functioning

types of diabetes:

-type 1

-type 2

-type 3

-latent autoimmune diabetes of adults

-GD

-prediabetes

type 1 DM:




*NO INSULIN PRODUCTION*




-typically affects young children/early puberty

, -from beta cell destruction leading to absolute insulin deficiency




-glucose derived from food cannot be stored in the liver




-genetic disposition




-will need insulin injections for life




-ketosis prone

type 2 DM:




*SOME INSULIN PRODUCTION*




-results from lifestyle, fmh




-decreased sensitivity to insulin and impaired beta cell function result in
decreased insulin production




-may develop hyperglycemic hyperosmolar syndrome

in DM2, insulin resistance can lead to:
