For the last week now, I've been drinking almost 2 gallons of water a day and urinating fequently. It is this feeling of no matter how much water I drink, my brian is telling me that I need water, and my mouth is craving water, yet my stomach is so full. I've had numbness in my feet just about everyday. I've had excessive hair loss. I went to my doctor and he sent me for blood and urine tests. When the results came back they were all normal. My family thought it would be dibetes because those are symtomps of it, but my blood suger came back fine. I dont know what it could be, anyone have any ideas?

  • Did he check your fasting glucose levels? Did you drink that nasty sweet sugar drink? DOM

  • No, I have not gone for that test. I talked to my doctor he said that my sugar level in my blood was 85, so there was no need to continue any sort of tests like that. He told me that I should go to another doctor to have him look at my tyroid, pituary glands, and adrenal glands. Thanks for the help.

  • Wow, I can't believe they wouldn't do this test for you. Diabetes should be ruled out, and a fasting glucose test tells way more than a simple blood test of what your blood sugar levels happen to be at one particular time. Has your doctor referred you to an endocrinologist? DOM

  • Yes he has referred me to an endocrinologist. However, when i called they told that they wouldnt take me because i was 18 and they were a pediatric endocrinologist office, so now its just a matter of finding a new doctor, and an endocrinologist. I'm still drinking about two gallons a day, its just such a pain. I can't go anywhere with a long drive, becuase i have to pee, or i need to stop somewhere and buy water because i finished my bottle in minute.

  • I defo wouldn't rule out diabetes anyway even with those results seeming fine. I'd also look into kidney problems aswell, can cause excessive thirst and going to the toilet to pee alot.

  • The most likely cause for your symptoms is diabetes insipidous, not diabetes mellitus. Many people, such as some making responses to your question, associate intense thirst and urinary frequency exclusively with DM. In the presence of normal glucose, however, this would not be the case and your doctor is correct that there is no need to perform a fasting glucose to determine clearance in the presence of a normal glucose result. Diabetes insipidous most often results from a dysregulation of vasopressin, that acts upon the kidneys to concentrate urine. In cases of diabetes insipidous, urine is typically unconcentrated and the affected person typically will indicate that their urine is more like water or clear. Causes for vasopressin dysregulation can vary from a disturbance at the pituitary gland or in nearly half the cases, it arises ideopathically, meaning that the cause is ultimately unknown. My suggestion here is to return to your primary care doctor and seek a trial prescription for desmopressin, which is a variant of vasopressin and will serve to concentrate your urine, thereby reducing the cycle you are presently experiencing. Secondly, you still need to continue on to the endocrinologist to have tests performed to try and identify whether an underlying cause can be determined. There are 4 types of diabetes insipidous, so a full evaluation is necessary to rule out a number of causes. Lastly, this needs to be evaluated promptly because excessive water intake can actually lead to H2O intoxication in some instances. Best regards, J Cottle, MD
