Gastrointestinal issues are a common but often unrecognized sign of infection.
In January 2020, a man who would become known as the first documented Covid-19 patient in the United States arrived at an urgent care clinic.
Two of his symptoms, a cough and a fever, were among those that would become known as the telltale symptoms of Covid. But the patient had also experienced two days of nausea and vomiting.
Many of us associate Covid with respiratory issues. But some people who get sick with the virus never experience a sore throat, coughing or body aches, said Dr. Peter Chin-Hong, an infectious disease specialist at the University of California, San Francisco. Certain people end up feeling more like they have food poisoning than anything else.
That’s because coronavirus is “like throwing a bomb in your body,” said Dr. Ken Cadwell, a professor of medicine at the University of Pennsylvania who studies how Covid affects the gut. “You’re going to feel that in multiple different organs, not just the lungs.”
With Covid cases climbing, and the so-called “FLiRT” variants fueling yet another summer spread, here’s how to spot, and address, the lesser-known gastrointestinal symptoms.
Recognizing and resolving stomach symptoms
In some people, gastrointestinal symptoms hit during the first few days of an infection, before they develop a fever and cough. But many people who only experience stomach symptoms “never think of it as Covid,” Dr. Chin-Hong said.
