Thanks for posting your query.
After reading whole query, there may be possibility of following disease: tropical sprue
, acute gastroenteritis
and acidity problems.
You should consult with physician / gastroenterologist and should go for following investigations: complete blood count
, renal function test, serum electrolytes, liver function test, ultrasound
imaging, thyroid profile, endoscopy and duodenal biopsy, blood sugar.
If all these test are normal then you may have long lasting persisting infection and should go for complete antibiotic course.
You should also take pure water and covered food and flies are the source of recurrent infection (as your symptoms suggest).
You should also do dietary changes, proton pump
inhibitors, and prokinetics.
