Burns when i pee, only when dehydrated. i have had this problem since i was 15, it burns a little when i pee but only when i haven't drank enough water. if i drink water it doesn't burn?

When you are a bit dehydrated, your urine is more concentrated which likely is why you feel a slight burning sensation. So, keep yourself hydrated by drinking plenty of fluids throughout the day. Good luck to you!

Agree with Dr. Ferranti. Drink enough water daily so that your urine is mostly colorless. For healthy diet: http://www.choosemyplate.gov/., exercise 30 minutes/day, have safe sex, no tobacco alcohol weed or street drugs. Get HPV and Covid vaccines. Wish you good health!
