Abstract
COVID-19 is a global health emergency that requires worldwide collaboration to control its spread. The scientific community is working to understand the different aspects of the post-COVID-19 syndrome and potential treatment strategies. Interestingly, there have been reports of gastrointestinal tract (GIT) involvement in the post-COVID-19 syndrome, suggesting the presence of both severe and mild GIT disorders. The development of the post-COVID-19- GIT syndrome involves various factors, such as impaired GIT mucosa cells, disruptions in the feeling of satiety, reduced blood supply due to the formation of small blood clots, and increased prostaglandin secretion caused by an excessive immune response. GIT symptoms have been observed in around 16% of COVID-19 patients. Other complications include kidney damage and prolonged impairment in the filtration and excretion functions of the glomeruli and tubules. The pathogenesis of post-COVID-19 renal syndrome involves factors, like an overactive immune response, reduced lung perfusion and oxygenation, viral infection in kidney tissues, endothelial dysfunction, and decreased blood volume. Roughly 20% of hospitalized patients experience renal manifestations after recovering from COVID-19.
