The vomiting and diarrhea that come with stomach virus symptoms can turn everyday routines like eating and drinking into a battle. It might be scary to see your kid go hours and hours without keeping down a single bite of nourishment, but rest assured: This is normal.
“When a child has a stomach virus, it’s really hard to eat. You don’t have much of an appetite,” says Preeti Parikh, MD, Pediatrician at The Mount Sinai Hospital. “Don’t worry about the food. Focus on the drinking and making sure they stay hydrated.”
Preeti Parikh, MD is the Executive Medical Director at GoodRx and served as the Chief Medical Officer of HealthiNation.
