Hi.
Thanks for your query.
Noted the history and understood the concerns.
The symptoms of bloating, nausea, feeling full hence do not want to eat, dizziness in spite of digestive medicines indicate that there may be sub-clinical intestinal infection that the body could not control, a sort of
gastroenteritis.
I would advise you the following in such a situation:
Get the stool test for three consecutive days.
Also get the blood tests for CBC, diabetes, thyroid and liver functions.
Clinical evaluation by your Doctor and correlation with the reports will help us to get the proper diagnosis and a course of an antibiotic,
metronidazole may help you the best.
Also take probiotics, digestive enzymes, activated charcoal tablets.
Take a PPI and
Domperidone.
All these things will surely help you to get well soon.
Rarely an Upper GI Endoscopy and
colonoscopy along with
ultrasonography may be needed to get a proper diagnosis and plan for further management.
