Hi, many thanks for the query!
Get Stool (Culture & Microscopy) done and then
start antibiotics as per the report, along with anti-spasmodics.
Also do CBC & Sr. electrolytes.
Drink plenty of oral fluids specially those containing salts, like ORS
Take Lacto-bacilli - Pre-biotics & Pro-biotics to replenish the gut flora
Wish you a good health. Take care.
