Hi,Dear,Thanks for your query to HCM.
Dear I read your query and reviewed it with context to your query facts.
I understood your health concerns and feel Concerned about them.
Based on the facts of your query, you seem to suffer from-
Celiac disease / could be from Du with Pyloric Stenosis/ or could be from Gall Bladder/TB abdomen?/ possibility of Renal cause is remote but needs to be kept in mind while assessing case of your niece.
Reviewing the story of your stomach pain with the negative CT Abdomen/ USG / and
endoscopy.
Colonoscopy would not help her much but needs to be done to rule out any Colonic pathology.
Treatement-
Contrast CT Abdomen would be more helpful in her case and would guide on any of the above possibilities.
Surgeons physical Assessment with Second Surgeons opinion would cross-check the various possibilities discussed above.
Above all if the reason still not found,I would suggest Laparsocopic Exploration of the abdominal cavity in case of your niece.
Remedy-
Avoid
Gluten in diet with lack of Wheat.
Be on the Rice +Yogurt diet with
Stress On Liquid and semi liquid diets with high
proteins Avoid Cheese and dairy products.
Vit B12 Tab-2500 mcmg daily to avoid the nutritional deficiency
