Why does diabetes cause me to be hungry, thirsty, and need to urinate frequently? Does anyone know?
Most of the time, people with undiagnosed diabetes have thirst and a lot of urination, but many loose their appetite. The reason is that the beta cells that create insulin are not working, or in the case of type 1 diabetes the autoimmune system targets them and kills them. There are 5 kinds of cells inside an islet cell, one of them is the beta cell which is where insulin is made. Without it, the body starts to have increased sugar levels and much of the metabolic system goes into disarray. http://www.healthcentral.com/diabetes/manage.html
Please let me know if you need more specific information.
the answer is in the etymology: diabetes is greek for peeing alot, and mellitus is greek for sweet- so, DM means u pee alot of sweet urine- this is how the old school docs would diagnose DM (before blood testing and urine ketones)- basically, when ur sugar gets high enough, ur kidney can't process it, and some sugar spills out into the urine- and since sugar absorbs water, more water is passed out in the urine, making u thirsty and likely hungry 2 (although Ann is right- alot of diabetics lose weight as their pre-diagnosis sugars are running high- probably burning up muscle/fat as all that fuel (sugar) is wasted via the urine)- this is why anyone who pees/drinks alot (especially @ night) should get a blood sugar test
