Could my doctor diagnose celiac disease with a colonoscopy?

Probably not. Celiac disease can be diagnosed by small intestine biopsies, done through an endoscope through the mouth. Colonoscopy comes from the other end (the anus) and probably wouldn't be able to get a diagnostic biopsy of the small intestine.

It could be possible that a colonoscopy diagnose celiac disease?

Possible. During colonoscopy, quite a number of physicians reach the terminal ileum, the last part of the small intestine. Celiac disease affects this part of the small intestine, so the physician can see the changes in the lining of the gut and confirm the diagnosis with biopsies taken from that area. Read more...

It is hard enough to remain gluten free when you try, since it can be found in unexpected items. Read more...

After an endoscopy and colonoscopy dr said he found scalloping that looked like celiac disease. Biopsy was negative. Should I go gluten free?

Celiac diagnosis. Try it! biopsy is the most definitive way to diagnose celiac disease, but when it's negative it doesn't totally rule it out. The inflammation can be patchy, and a gluten-free diet before scoping can clear you up. Also, some are gluten intolerant without having the disease, and both groups feel better with the diet. It never hurts to try the diet. It's only critical to stick to the diet if proven. Read more...

Similar symptoms. Ibd and celiac disease have been reported together in some patients. Some patients with ibd have also reported a relapse in symptoms on gluten free diet, but a direct relationship has not been definitively established. Celiac disease is diagnosed with the combination of upper endoscopy, duodenum (small intestine) biopsy, and blood test for celiac antibodies. Read more...

Thyroid issue? . Working out 5 days a week is very commendable. I wonder how many calories you burn. 1 pound of fat = 3500 calories. Your calorie requirement depends on your height, age and sex. If it is 1700 per day and you are eating 1600 per day and burning an extra 1000 calories a week working out then in about 3 weeks you should lose 1 pound. Check to see what you require and how much you are burning up. Read more...
