Thanks for posting your query on DoctorSpring.com.
I am Dr.R.K and I am pleased to assist you.
I went through your post in detail and noted your symptoms of chronic diarrhea, malabsorption, weight loss and blood in stool.
It is very important that a conclusive diagnosis be reached for your condition. Once this is done, appropriate management will resolve your symptoms. In this regard you need more tests to be done. Inflammatory bowel disease is one of the possibilities and since you had blood in stools, a colonoscopy test has to be done. In this test a long slender tube is inserted through the anal opening and the inside of the large bowel is examined.
Another possibility is intestinal tuberculosis. The above mentioned colonoscopy test itself will help to diagnose intestinal tuberculosis.
Chronic diarrhea, malabsorption and iron deficiency can also occur in celiac disease. So this too has to be ruled out. An upper GI endoscopy with small biopsy and tissue Transglutaminase antibody blood test are to be done.
In summary, the following tests have to be done:
2. Upper GI Endoscopy with biopsy.
3. Tissue Transglutaminase Antibody Test.
I hope that answers your question. You can get these tests done and get back to me with the results.
Let me know if I can assist you further.
