In fact, the gut microbiome of people who did not develop long COVID was similar to that of a group of healthy controls who provided fecal samples before the pandemic. Additionally, muscularis propria-resident macrophages, in close apposition with the cell bodies of enteric neurons, acquire tissue-protective phenotypes that prevented neuronal loss after infection10. The pathophysiology of post-infectious-gutbrain disorders is still obscure and limited by small size studies and different time points evaluated after infection. Then, even if the process of digestion remains normal, you may frequently have symptoms like pain or a distressing change in your bowel movements, such as diarrhea or constipation.

Since 2020, we've known that the virus particles that cause lung illness also infect the gastrointestinal (GI) tract: the esophagus, stomach, small intestines, and colon. Constipation and/or diarrhea is another sign, some people actually have alternating constipation and diarrhea post COVID. There are also around 100 times more ACE-2 receptors in the GI tract than respiratory organs, so it may be able to house more viruses when it acquires an infection. But COVID-19 can cause symptoms you may not expect, including: Digestive symptoms.
