Coronavirus, COVID-19, IBS and the Low FODMAP Diet

This article is for informational purposes only and not a substitute for medical advice. Please speak with your doctor, dietitian, or gastroenterologist if you have any concerns regarding coronavirus or Irritable Bowel Syndrome (IBS).

Coronavirus and Gut Health After the Pandemic

Even in the post-pandemic world, the coronavirus (COVID-19) continues to influence how we understand gut health and digestion. Many people with Irritable Bowel Syndrome (IBS) report digestive symptoms such as bloating, diarrhoea, and abdominal discomfort during or after infection. Studies suggest that the coronavirus can disrupt the gut microbiome, which may lead to new or worsened IBS symptoms.

For people following the low FODMAP diet, this can make symptom management more complex. While severe illness is now far less common thanks to vaccination and improved treatments, long-term digestive effects of COVID-19 remain an important topic for gut health research.

What We Know About COVID-19 and the Digestive Tract

Medical research has shown that coronavirus can infect the gastrointestinal tract and leave traces in stool samples even after respiratory symptoms have cleared. This helps explain why some COVID-19 patients experience ongoing digestive symptoms after recovery.

For most people with IBS, coronavirus infection does not appear to increase the risk of severe illness. However, people with conditions such as inflammatory bowel disease (IBD), Crohn’s disease, or ulcerative colitis—especially those using immune-suppressing medication—should continue to follow medical guidance closely.

Supporting Your Gut After COVID-19

If you are managing IBS after a coronavirus infection, the following steps can support gut recovery and reduce symptom flare-ups:

  • Continue your low FODMAP plan: Maintain your elimination and reintroduction process but ensure your diet remains balanced and nutrient-rich.
  • Rebuild your microbiome: Add low FODMAP probiotic foods like lactose-free yogurt, or ask your dietitian about suitable probiotic supplements.
  • Stay hydrated and rest: Fatigue and dehydration are common after illness and can worsen IBS symptoms.
  • Manage stress: Stress affects both digestion and the immune system. Relaxation techniques, yoga, or daily walks can help regulate the gut–brain axis.
  • Monitor ongoing symptoms: If abdominal pain, bloating, or bowel changes persist, speak with a healthcare professional for tailored advice.

Living Well With IBS Post-Coronavirus

The coronavirus pandemic highlighted how closely gut health, immunity, and stress are linked. For those living with IBS, long-term management now means more than diet alone—it’s about supporting the body’s natural balance. Consistent sleep, movement, hydration, and mindful eating all play key roles in keeping digestion and overall health strong in the years ahead.
