My son drinks a lot pees a lot don't eat a lot but eats mostly carbs could he be diabetic? i was when i was pregnant

Possible: It's possible, or he may urinate a lot just because he drinks a lot. It he's obese w/family history of diabetes, he needs to be checked out.

Any weight loss ?: Unless your kid is losing weight in spite of his extra eating and drinking, diabetes is less likely than a drinking habit.The more you drink, the more you change how your kidney handles the water in your blood, tossing more of it out to stay in balance.Diabetics loose glucose in the urine as well as the fluid, so a simple dipstick urine can often separate the two.Diabetics pee out glucose.
