Q

Pathiophysiology of diabetes

A

*Insufficient amount of insulin Glucose cannot enter cell=energy depleted
*cellular starvation and uses fats and proteins for energy
*ketogenesis= metabolizationi of fat
*glyconegenesis= breakdown of amino acids(protein)
*break down of amino acids=protein & ketones in urine
*high blood glucose concentration pulls H20 from cell to bloodstream and causes cellular dehydration
(thirsty, voiding more) eventually this will spill into urine
