Study Shows Increase in Digestive Disorders During COVID-19 Pandemic

A study led by Cedars-Sinai investigators found a significant increase in chronic digestive disorders, such as irritable bowel syndrome, during the COVID-19 pandemic. The study, published in Neurogastroenterology & Motility, suggests a link between pandemic-related stress and gut-brain axis.

Using data from a national online study, rates of digestive issues like irritable bowel syndrome and chronic idiopathic constipation rose notably. These findings highlight the impact of the pandemic on digestive health.

Conditions like irritable bowel syndrome and chronic idiopathic constipation, known as disorders of gut-brain interaction, are common gastrointestinal disorders influenced by interactions between the gut and nervous system.

Approximately 40% of people in the U.S. may meet diagnostic criteria for at least one gut-brain interaction disorder, leading to significant healthcare burden and reduced quality of life.

According to lead author Christopher V. Almario, MD, MSHPM, these disorders involve chronic gastrointestinal symptoms often exacerbated by psychological stress.

Researchers analyzed data from over 160,000 U.S. adults who participated in a national online survey from May 2020 to May 2022 to understand the link between viral infection and digestive health.

Key findings revealed an increase in irritable bowel syndrome rates from 6% in May 2020 to 11% in May 2022, while chronic idiopathic constipation rose slightly from 6.0% to 6.4%.

The study emphasizes the importance of recognizing the impact of the pandemic on mental health and its potential effects on gut health, leading to or worsening conditions like irritable bowel syndrome.

Lead author Brennan Spiegel, MD, MSHS, calls for a renewed focus on gastrointestinal health post-pandemic, highlighting the need for healthcare providers to address the long-term effects of the pandemic on digestive health.
