Hi.
Thanks for your query.
Noted your history of stomach problems which includes cramps, alternate
diarrhea and hard stools, undigested food in stools, nausea, does not want to eat, stopped the foods for which allergy was found on testing,
colonoscopy was normal .
All these symptoms look to be due to IBS that is
irritable bowel syndrome.
I would advise you the following:
Get other tests too:
Stool tests for 3 consecutive days.
Ultrasonography of the abdomen.
Tests of blood particularly for CBC, sugar,
thyroid, liver and kidney functions.
Is the tests find anything positive, get treated accordingly.
If all the tests area negative, get the line of treatment on the basis of IBS.
