I recently undergone medical examination. it was seen that i have high uric acid level and enlarged prostate. does they relate to each other?

No such relation: Uric acid can be high but it has no relation to enlarged prostate. I seriously doubt that your prostate is enlarged at the age of 22 years! This only happens in middle/older males(over 50 years of age). High Uric acid needs treatment. So you should see a doctor to monitor your uric acid at least once yearly. There is good medicine for its treatment. Uncontrolled Uric acid can cause Arthritis(Gout)
