I am 67 years old. why do i have a weak urine stream only in the morning?

Enlarged prostate: MAY be the issue. Your doc can check it. The prostate wraps around the urethra and can pinch off the flow of urine. Very common in older men. A natural product called "ProstaThera" by the ProThera company can be helpful but you need a licensed professional to get it for you. Peace and good health.

Benign Prostatic: Hyperplasia also called benign enlargement of the prostate. BPH is very common in patients over 60 years of age. The weak urine stream, the urgency to urinate are common symptoms. See your PCP first. Your primary care physician may decide that your symptoms should be treated by a urologist.
