Some patients with novel coronavirus pneumonia will have symptoms such as stomach discomfort, nausea and vomiting, but it is not necessarily the novel coronavirus that causes stomach discomfort. Because there are many other diseases that can cause stomach discomfort, such as indigestion, gastric ulcer, duodenal ulcer, and even esophageal cancer and gastric cancer in elderly people can have stomach discomfort, and further examination in the gastroenterology department of a hospital is needed to know what the disease is. If you want to diagnose the new coronavirus, you can’t rely on symptoms alone, but rather on nucleic acid from respiratory secretions and CT of the chest, and only if all three are positive can you diagnose a patient with new coronavirus pneumonia, and you can’t tell by symptoms alone.
