Question: Hello, I was diagnosed with IBS several years ago. Not as bad as some people get. Pain and cramping sometime. Lately I have been passing much watery gas . This morning I noticed that my stool (which was a small amount)was black. Do you think this is just the IBS or something more serious going on?

Thanks for posting your query.
I am Dr.Ratnakar Kini and I am pleased to answer your query.

Black stool can be both serious and harmless.
Serious because it can indicate upper gastrointestinal bleed and harmless because it can be due to certain medications like pepto bismol, iron supplements and certain food items like blue berries.

So if the stool continues to be black, consult your doctor. He may do a rectal examination and may even order for a stool test. If he confirms it as due to bleed he may perform an upper GI endoscopy to find the source of bleed.

I hope that answers your question.

About a week ago I was having a bad case of irratable bowel that lasted all day. I took Pepto Bismol 2 large doses and it didnt seem to help so I went to the ER. The doctor there ordered a CT scan of my stomach area. This was about 2 hours after I had taken the Pepto Bismol. I did mention that to the doctor and Tech. The TC scan reading was a mass in my small intestines. I have an appointment with a cancer doctor. My question could the Pepto Bismol have given a false reading in my CT scan. The doctor gave me Bentyl and Im doing fine now.

My husband has had a gray clay like bowel movement. No other unusual symptoms at this time. He took pepto bismol 5 days ago. Could this affect him so much later? How many light clay like stools can you have before considering it serious needing emergent medical attention?

Hello. My husband, son and I all ate fish from a fast food restaurant on Thursday. On Friday, I had diarrhea over the course of the day with some abdominal pain, weakness and fatigue. I felt better by that evening. My son was a little nauseous on Friday night, but felt better with Pepto Bismol and tums. My husband became feverish with chills, severe weakness, and severe diarrhea on Friday evening. He has continued to feel weak since then with diarrhea and some nausea. He has no appetite. I have been offering crackers, soup, ginger ale, and popsicles. He is very tired and has been sleeping most of 2 + days. He does not think he needs to see the Dr. ..... He is diabetic (oral meds) and is being treated with hormones for prostate cancer. Thank you for your help.
