Q

What is the pathophysiology of Diabetes?

A
  • Pancreas is the primary affected organ
  • result of lack of insulin levels or inability to use available insulin
  • insulin is produced by beta cells in the pancreas then release into the blood stream and used as a carrier molecule for glucose in order to be transported into cells
  • insulin also allows excess glucose to be converted into storage called glycogen within the cell
  • the pancreas alpha cell produce a hormone called glucagon
  • glucagon is secreted into the bloodstream with the blood sugar levels drop and it causes the breakdown of glycogen (stored sugar) and stored fats back into glucose to where the body can use it for energy (glycogenolysis)
