Gastroenteritis or stomach flu is a bowel infection that causes inflammation in the stomach and intestines and is accompanied by diarrhea, nausea, and vomiting (1). In the US, acute gastroenteritis in children accounts for 200,000 hospitalizations and 300 deaths in children every year (2). However, gastroenteritis infections are not usually severe, and the symptoms last for around two days. It usually takes around seven days for the infection to subside completely.

How Is Gastroenteritis Treated?

Some important considerations about gastroenteritis treatment are (3):

Mild cases of gastroenteritis do not need any treatment and subside by themselves. Oral hydration and ORS can be given in proper dilution to compensate for the fluid loss.

Zinc supplementation in proper dose is given to children with acute watery diarrhea as it compensates for the loss and reduces the severity and duration of diarrhea (12).

Do not give any medication to children without the doctor’s advice. If your child has a fever, give acetaminophen (4).

Probiotics may be used in acute watery diarrhea only, as prescribed by your doctor (13).

Racecadotril is a prescription medication for severe watery diarrhea because it helps reduce fluid loss through stools. It may be given to children above three months only if advised by your doctor (4).

Antibiotic treatment is not required for viral gastroenteritis (9). However, antibiotics will be required for cholera or bloody stools due to bacillary dysentery. Antibiotics should never be used unless prescribed by your doctor.
