Hello;
Welcome to HealthcareMagic
After a age of 45-50 yrs it is common for some males to have some amount of enlargement of
prostate gland.
This condition is called as Benign prostatic hyperplasia(
BPH).
Your PSA values are also normal so it is more likely a benign enlargement and not cancer so please do not worry.
As for the lifestyle changes you can follow these steps:-
-Urinate when you first get the urge,
-Avoid alcohol and caffeine, especially after dinner,
-Don't drink a lot of fluid within 2 hours of bedtime,
-Reduce
stress and exercise regularly.
This should help you in tackling your problem.
Take care
Regards
