Hello doctor,

I am 27 years old, 247 lb male. I have been having a problem with blood in stool for two years now. Sometimes, I have blood in stool for two or three days and sometimes goes away for months with no blood. For three months, I did not have blood in the stool. Now I started to drive a truck 12 to 14 hours a day sitting on the truck and I started having blood again. I am very scared. I may have colon cancer. My doctor did a blood test on me one month ago including vitamins and minerals and everything came back 100 %. I told her I am scared that I may have colon cancer she said no you do not and you do not need a colonoscopy. How does she know? I have blood in stool for two years now and not in normal shape.

Hi,

Welcome to icliniq.com.

See it is difficult to say what is the reason for blood in your stools. But definitely, this is not a normal thing. You could be having piles.Actually, piles are the most common cause of blood in stools. That is why your physician must have in general told you to relieve your stress. My recommendations would be to take a soft, and a blended diet. Take plenty of fluids. Make sure you do not strain during stools. If you still have the blood while you are not straining in stools and you are not constipated, you would definitely require a colonoscopy.

Thank you doctor,

Do you think if it was colon cancer my blood would show something? And because I sit driving for 12 hours a day, it can cause that?

Hi,

Welcome back to icliniq.com.

Long sitting can cause blood in stools if you have rectal prolapse. Blood tests in colon cancer may usually not throw any light. You can go to a nearby surgeon and ask him to examine you and do a proctoscopy. If proctoscopy is normal, then you may need a colonoscopy.
