Hello dear
Warm  welcome to Healthcaremagic.com
I have evaluated your query thoroughly .
*  This is in relation with intestine infection .
Consume plenty of liquids .
Prefer soft , light  , bland , vegan  diet  with fresh curd preferably .
Avoid  all types of  oily , spicy , non veg , hot beverages , junk foods , dairy fat .
Intake of PPI  ( as 
omeprazole ) , antibiotics  ( with 
metronidazole on pack ) 
pro biotics ( with lacto bacillus ) help  to  give  faster  recovery .
Hope this clears your doubt  .
Wishing you fine recovery .
