Explain the pathophysiology of the three P’s for (polyuria, polydipsia, polyphagia)” with the given diagnosis of Type I DM.

The 3 P’s of diabetes are polydispia ,polyuria,polyphagia, it means increases in thirst, urination, and appetite, most often otccur separately, They develop often  early in type 1 and type 2 diabetes slowly. Diabetes is a chronic  medical condition, that is uncureable  but is edible. The important part  of the management   is to be familar with the signs and symptoms  of the condition.  Polydipsia is an increase in thirst,It occurs in diabetes when blood v glucose is high, the  kidney work hard to remove the excess glucose by producing more urine, Because the body is loosing more water, the brain send signal to drink more. Polyuria is passing urine more than normal, when blood glucose is high, the body will work to get rid of the glucose via urination.fluid is replaced as it losses more from urination. Polyphagia is  extreme hunger to replacec the glucose,

(polyuria) Hyperglycemia acts as an osmotic diuretic. The amount of glucose filtered by the glomeruli of the kidneys exceeds the amount that can be reabsorbed by the renal tubules. Glycosuria results accompanied by large amounts of water lost in the urine. (polydipsia) Because elevated blood glucose levels, water is osmotically attracted from body cells which results in intracellular dehydration and hypothalamic stimulation of thirst. (polyphagia) Depletion of cellular stores of carbohydrates, fats, and proteins results in cellular starvation and a corresponding increase in hunger.
