Stomach ache is a symptom of COVID as much fever, sore throat and runny nose are. “A recent study showed that 1 in 5 people who tested positive for COVID-19 had at least one gastrointestinal symptom, such as diarrhea, vomiting, or belly pain. Of those hospitalized, 25.9% had gastrointestinal issues,” a report carried by WebMD says.
In March 2020, just around when the COVID-19 disease was declared a global pandemic, a report carried by the Forbes said that stomach ache and diarrhea may be the first signs of COVID infection. The report referred to a study published in the American Journal of Gastroenterology. “The take-away from this study is that COVID-19 patients diagnosed with gastrointestinal symptoms had an adverse outcome and increased risk of death compared to those without the symptoms. This underscores the need to evaluate GI symptoms— nausea, vomiting or diarrhea— as a potential presentation of COVID-19, prior to development of respiratory symptoms,” Forbes reported.
Another study of 25,252 individuals found that the common gastrointestinal symptoms of COVID are lack of appetite, loss of smell and taste, diarrhea, nausea, abdominal pain and vomiting of blood.
