On Mar. 7, 2023, researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs St. Louis Health Care system reported that People who have had COVID-19 are at increased risk of developing gastrointestinal (GI) disorders within a year after infection compared with people who havenﾒt been infected, according to an analysis of federal health data.

Such conditions include liver problems, acute pancreatitis, irritable bowel syndrome, acid reflux and ulcers in the lining of the stomach or upper intestine. The post-COVID-19 GI tract also is associated with an increased likelihood of constipation, diarrhea, abdominal pain, bloating and vomiting. The study is published in Nature Communications.
