[|Human|] what can cause bleeding from the penisI am a 37 year old man that weighs 180 lbs and i am about 55. i have recently been diagnosed with gastroperesis and had a cancerous colon polyp removed. this morning when i peed, there was a little bit of blood and some spots in my underwear. what can cause this??
[|AI|]  Hi. Was there any associated pain with the blood? Was the blood in the beginning of the urine or middle or end? That can help indicate the cause of the blood. Anyway, you should get an Ultrasound of Abdomen and PUB done as well as a Urine culture done to rule out any infection. Also, please observe carefully if it happens again. Please let me know the answers and reports. You can do the same by going to Ask a Specialist questions. Meanwhile, increase your water and fluid intake and observe for recurrence of bleeding. Take care and look forward to hearing from you.  Chat Doctor.
