Yes,the symptoms you are having of watery diarrhea & some vomiting from last 3 days can be due to a condition called gastroenteritis what you call as stomach flu. Gastroenteritis is the irritation and inflammation of the digestive tract.
Its most common causes are:Food poisoning, viral infections, food allergies, improper diet, and intestinal parasites or bacterial infections.
You can take the following medications:
-Tab meclizine hydrochloride(brand name: Dramamine).This will help you greatly in stopping the vomiting.
-Tab.Acetaminophen for relief from stomach ache cramps
- Take tab. Loperamide to stop the diarrhea & loose stools.
All these medications are available as OTC(over the counter) without prescription & will help you greatly.If still the symptoms persists,then you need to go to ER as tests & antibiotics will be prescribed accordingly.
Usually & most likely these symptoms get resolved by above described medications.Don’t take solid diet.Let your stomach rest for few hours after food poisoning.
Hope this helped
