How is celiac disease generally diagnosed?

Can I diagnose myself for celiac disease?

No. You need blood tests for celiac antibodies and an endoscopy to confirm the diagnosis. However, you can eliminate glutens from your diet and see if that helps. Read more...
Bad idea. Placing yourself on a gluten free diet is a new cult idea out there & you may believe you have "diagnosed " yourself. It might be valid, or totally unrelated. Since those with true celiac disease are at higher risk of non-celiac medical conditions, you would risk missing them for years, when a doc would know to look.You are better of limiting your DIY to fixing up your house.

It could be possible that a colonoscopy diagnose celiac disease?

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...

I was diagnose with celiac disease after being misdiagnose repeatedly. Gluten-free diet helps but I'm unemployed & the food's expensive. What do I do?

Not expensive. Buying and cooking rice is not expensive, eating legumes such as chickpeas and lentils, red beans and black beans with the rice is not expensive. There are many inexpensive beans and grains that make a whole protein, provide carbohydrates and good nutrition on a celiac diet. Peanut butter also is not expensive for a jar. Read more...

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. Read more...
