A review of 36 published studies on the symptoms of coronavirus found that in many patients, infection is only caused by an upset gastrointestinal tract. Because of this, doctors often make mistakes in diagnosis.
In studies that analyzed scientists from the University of Alberta studied the medical records of more than a thousand patients with coronavirus. It revealed. that about 16% of infected people carry COVID-19 exclusively with gastroenterological symptoms: nausea, vomiting, diarrhea, loss of appetite, stomach pain. Abdominal MRI revealed signs of inflammation in the large and small intestines in these patients, and sometimes cysts on the intestinal walls.
In another 18% of patients, signs of a gastrointestinal disorder appear along with other symptoms of coronavirus: fever, fever, difficulty breathing.
The authors of the review note that doctors around the world focus primarily on respiratory symptoms when diagnosing, so this atypical manifestation of infection is often underestimated. In addition, the patients themselves often attribute these symptoms to a gastrointestinal disorder and do not go to the doctor.
This is not the first work to describe the prevalence of gastrointestinal symptoms in coronavirus. Overview a study in China showed that of 204 COVID-19 patients, more than half complained of vomiting, nausea and diarrhea. In American research with the participation of 4.2 thousand patients, gastroenterological symptoms were recorded in 18% of cases.
Formerly American dermatologists identified Another common manifestation of the coronavirus, which sometimes manifests itself without other symptoms, is a lesion on the skin of the toes that looks like severe frostbite. In such cases, irritation of a bright red color appears, which later acquires a purple tint. Sometimes this condition is accompanied by painful sensations in the fingers, itching and blisters appear. According to experts, “purple fingers” should be added to the criteria for diagnosing coronavirus.
