Purpose Of Review:
Ten percentage of patients with coronavirus disease (COVID)-19 report having gastrointestinal (GI) symptoms as severe acute respiratory syndrome coronavirus-2 (SARS-CoV2) not only infects the pulmonary but also the GI tract. GI infections including that due to viral infection is known to cause postinfection disorders of gut-brain interaction (DGBI); hence, we wish to review the long-term GI consequences following COVID-19, particularly post-COVID-19 DGBI.
Recent Findings:
At least 12 cohort studies, four of which also included controls documented the occurrence of post-COVID-19 DGBI, particularly IBS following COVID-19. The risk factors for post-COVID-19 DGBI included female gender, symptomatic COVID-19, particularly GI symptoms, the severity of COVID-19, the occurrence of anosmia and ageusia, use of antibiotics and hospitalization during the acute illness, persistent GI symptoms beyond 1 month after recovery, presence of mental health factors, The putative mechanisms for post-COVID-19 DGBI include altered gut motility, visceral hypersensitivity, gut microbiota dysbiosis, GI inflammation, and immune activation, changes in intestinal permeability, and alterations in the enteroendocrine system and serotonin metabolism.
Summary:
Long-term sequelae of SARS-CoV2 infection may persist even after recovery from COVID-19. Patients with COVID-19 are more likely to develop post-COVID-19 IBS than healthy controls. Post-COVID-19 IBS may pose a substantial healthcare burden to society.

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
