Hi.
Thanks for your query.
Noted the history and understood your concerns.
Pain in the upper abdomen with fluffy stool almost 5 times a day and loosing 16 lbs in 4 months indicates the following:
Enterocolitis meaning infection or inflammation of the intestinal tract due to some disease or disorder that needs further proper investigations.
Another reason can be chronic
pancreatitis.
I would advise you the following in such a situation:
MRCP or contrast enhanced CT scan of the abdomen.
Blood tests for CBC, liver and pancreatic functions, thyroid function and for
diabetes .
Tests of stool for three consecutive days.
Upper GI
Endoscopy.
Colonoscopy.
Get the treatment as per the clinical evaluation, examination and investigations reports.
You may need the following:
Pancreatic enzyme supplements to be taken with food.
A course of an antibiotic,
metronidazole if infection is found.
Probiotics, multivitamins in therapeutic dosages.
