A review of 36 published studies of COVID-19 that included thousands of patients found that nearly a fifth of those infected may experience only gastrointestinal symptoms during the battle with coronavirus, no. such as loss of appetite, nausea, vomiting, diarrhea, and stomach pain.
The number of people affected by these symptoms may be a low number, researchers say, because report a pandemic early before doctors know what to look for.
Researchers from the University of Alberta in Canada say their analysis of the documents published since the start of the pandemic until July 15 is a reminder for doctors as well as the public to consider. These symptoms are potential signs of COVID-19.
Study co-author Dr. Mitch Wilson, radiologist and clinical lecturer in the faculty of medicine and dentistry at the University of Alberta, said in a November newsletter: “Seeing these things is not necessarily tell us the patient has COVID-19. 3.
“It could be due to many potential reasons. But one of the underlying causes is a viral infection and in an environment where COVID-19 is very common, that’s something to consider and potentially recommend a doctor, ”added Wilson.
Doctors and scientists know that the most common symptoms of COVID-19 are fever, cough, fatigue, and shortness of breath, but more evidence continues to suggest gastrointestinal problems, as well as problems. cognitive and cardiovascular, as well as additional signs of coronavirus infection.
Out of 36 studies reviewed, an article in May found that more than 50% of 204 patients with coronavirus in China reported digestive problems such as diarrhea, vomiting, and abdominal pain.
Another study published in May of 4,234 COVID-19 patients in the US revealed that about 18% of them had gastrointestinal symptoms.
The review found that 18% of patients in 36 studies had these symptoms along with some other more common symptoms. Whereas, 16% of cases COVID-19 has only gastrointestinal symptoms and nothing else.
According to the study, a CT scan of the abdomen revealed inflammation in the small and large intestines, a fluid-filled colon, cysts on the intestinal wall, and abdominal swelling in patients with these symptoms, according to the study.
Researchers say these signs are rare and may indicate that the disease has progressed, but radiologists should be “vigilant” while imaging a suspected patient with COVID-19. .
The study was published in September in the journal Abdominal X-ray.
