Thanks for your question on HCM.
In my opinion you are having acute gastroenteritis
. This is due to stomach infection
. Mostly caused by feaco-oral route.
So try to follow these steps for better symptomatic relief.
1. Drink plenty of fluids. Keep yourself hydrated. Drink ORS
(Oral Rehydration Solution).
2. Start antibiotics.
3. Start probiotics.
4. Avoid junk food. Eat only freshly prepared and properly cooked food.
If not improve in 5 days than get done stool examination.
