My son is 1 years old and 3 month he drinks a lot of water really a lot. i worry can it be signs of diabetis?

Only if new onset: I get that question a lot. If there is a sudden increase in volume or urination than I would be more concerned. In any case, if u are really worried about it his doctor could do a quick finger stick in the office to make sure.

See you doctor.: You should have your child evaluated by his doctor. Excessive thirst(polydipsia) and excessive urination (polyuria) can be signs and symptoms of diabetes mellitus

Unlikely the issue: Most at this age are habit drinkers.They enjoy the attention and the new skill they have toting their sipy cup around and having you fill it often. They don't wake up to drink or do as much on trips.Diabetics at this age will drink and eat a lot, lose weight, and soon become very sick.A simple urine test can detect excess glucose that comes with diabetes. There are other rare causes, talk with doc
