Why Do People With Diabetes Have Symptoms Of Excessive Thirst And Urination?
Posted in Definition on 06. Feb, 2010
This was a question for sample essay questions, and I understand why more glucose is excreted in the urine when you have diabetes but I dont see how that would increase thirst or urination? Would it mess with the concentration of urine in the nephrons?
The excess glucose in the urine causes excessive water to enter the urine due to differences in osmotic pressure (increasing urination frequency and volume). This causes a loss of water that leads to an increased drive to replace it (increased thirst).
