COVID-19 can have a negative impact on the health of the stomach: the stomach can suffer both from inflammation due to coronavirus infection and from aggressive exposure to medications, gastroenterologist Sergey Vyalov says. In an interview, the specialist said that when infected with coronavirus, almost any organ can be affected. According to him, an overexposed person may develop a stomach ulcer. However, according to him, "first of all, such complications may develop in people with diseases of the gastrointestinal tract. As Vyalov said, the enzyme ACE2, which interacts with coronavirus, is also found in the stomach. The virus that binds to this protein can negatively affect digestive organs, provoking inflammation of their tissues and the appearance of disease-causing symptoms. "A person with gastritis can turn into a person with an ulcer because of the action of the coronavirus," the doctor said. The likelihood of a gastric ulcer also increases with COVID-19 because of its treatment, he said. Specifically, anti-inflammatory, antiviral, and antipyretic medications can have side effects that negatively affect the gastric mucosa. According to the specialist, a patient with an ulcer may not experience severe pain - only some discomfort after eating. "When we eat something, food immediately enters the stomach, and if there is discomfort, we can talk about an ulcer," Vyalov said. If such discomfort occurs regularly, the specialist recommends consulting a doctor.
