Blood in my stool while on my period

So I have very irregular periods. I have one every couple months. Doctors say it's because of my stress level. Well recently I started my period, and there is a significant amount of blood in my stool each time. Should I be worried or is this common?

Dear LizHay: There are several possible reasons to have blood in the stool during menstruation:

1. Endometriosis of the bowel--Endometriosis implants are similar tissue to the lining of the uterus. Thus, endometriosis implants will bleed at the time of flow where ever the endo has attached itself (bowel, bladder, even as far away as the lungs). In your specific case it would be unusual for this type of bleeding to onset suddenly with large amounts of blood passed.

2. Internal hemorrhoid---Some women will become constipated during the premenstrual week. If this occurs and there is a small internal hemorrhoid there can be bright red bleeding when the hemorrhoid is abraded by hard stool.

3. Bowel bleeding coincidental to menstruation---Large amounts of bright red bleeding can arise from polyps inside the bowel, or much more remotely from rectal cancer.

Bottom line, this is NOT a common finding so I would really urge you to see your MD or clinic. They can use a clear plastic, cone-shaped device to look just inside the anus for sources of the bleeding. If it is not apparent then a flex sigmoidoscopy or colonoscopy might be needed.

Yours,
Jane
