My 4yo son is peeing every 15 min (but only a tiny amt). he's not thirstier than usual, though he has been hungrier lately. should i worry?

Take to MD: If this has been going on for more than 90 minutes, I would get him to the MD, urgent care, ER right now. Keep him hydrated in the meantime. Important to have this checked , particularly at his age. Good Luck.

Frequency : Diabetes, urinary tract infections, irritation of the urethra, or even chronic constipation can cause urinary frequency. A check with your pediatrician is a good idea.
