One In Five Covid Patients Only Show Diarrhea and Other Gastro Symptoms, Says Study
Toronto: Almost one in five patients with Covid-19 may only show gastrointestinal symptoms including loss of appetite, nausea, vomiting, diarrhoea and generalised abdominal pain, according to a review of academic studies.
The findings of the review, published in the journal Abdominal Radiology, suggest abdominal radiologists need to remain vigilant during the pandemic while imaging patients.
“There’s a growing amount of literature showing that abdominal symptomatology is a common presentation for Covid-19,” said Mitch Wilson, a radiologist and clinical lecturer in the University of Alberta in Canada.
The researchers examined findings from 36 studies published through July 15 to reach their conclusions.
In addition to gastrointestinal symptoms, they also determined potential signs radiologists should look for while conducting abdominal imaging that could be evidence of Covid-19 infection.
Those signs include inflammation of the small and large bowel, air within the bowel wall (pneumatosis) and bowel perforation (pneumoperitoneum).
The signs are quite rare, said the researchers, and could indicate patients with advanced disease.
“Seeing these things is not necessarily telling us a patient has Covid-19,” said Wilson.
“It could be from a variety of potential causes. But one of those potential causes is infection from the virus, and in an environment where Covid-19 is very prevalent, it’s something to consider and potentially raise as a possibility to the referring physician.”
