My stool has been black, green, and bloody. I have hemorrhoids. I go up to 4 times a day, with different consistency. I have gas and bloating my MCV is 101.0. My MCH is 33.4. I wonder if I could have celiac; my grandson does.

Four Months ago I started feeling nauseous after eating. I was bloated and felt like throwing up which I did an hour after eating. I became very weak and felt like passing out. This kept happening for another week. Within 4 hours of eating I would have a diarrhea bowel movement and the stool would be greenish. Sometimes it would just be loose stool but in the last 4 months I no longer feel hungry. Maybe because I am always bloated after eating. It doesn"t matter what I eat, the results are the same. I went to the emergency room one night and they checked my heart, did blood samples and found nothing. I saw the doctor about 6 times and they also did stool tests, blood work, thyroid tests, and found no virus or bacteria. Everything came back negative. Next, the doctor wants to do a colon scope and an endoscopy of the stomach. Since it is the intestines, I will do that test but I don"t want a tube put down my throat into my stomach. I constantly feel cramps and pains in the intestines especially after eating. Now it is usually the next day before diarrhea after eating and the stool is still green.

My stools became greasy and lightly brown after 2 weeks of using vitamin D3, I wonder if it is from the vitamin.

I was diagnosed with celiac disease 7 months ago, but I'm guessing I've had it for many years. Over the past 20 years, I've had stomach issues and frequent diarrhea issues, and have run tests, colonoscopies, endoscopies, with no conclusions. I'm on a strict gluten free diet, yet periodically I get intense pain/cramps in my upper abdomen area, and have yellowy stool both diarrhea and non-diarrhea.

I had normally formed, brown-colored stool, then after a few days of stopping drinking Diet Coke (my only diet change) it is light, clay-colored.
