Irritable Bowel Syndrome (IBS)

IBS is a common long-term condition of the digestive system. It's classified as a disorder of gut-brain interaction: the gut looks normal on standard tests, but how it moves and senses is altered.

About IBS

Clinicians diagnose IBS from its symptom pattern: recurring abdominal pain linked to bowel movements or changes in stool frequency or form. IBS is grouped by the main stool pattern: constipation, diarrhea or mixed.

Common symptoms and challenges

  • Abdominal pain or cramping related to bowel movements
  • Bloating and gas
  • Diarrhea, constipation, or both
  • Food-related symptoms and unpredictable flares

Biological factors

Well established: Altered gut motility, increased gut sensitivity and gut-brain signalling all play a role. IBS can begin after a gut infection.

Emerging research: Studies have found differences in the gut microbiome of people with IBS, but there's no microbiome pattern that diagnoses IBS.

Overlapping conditions: Guidelines recommend checking for celiac disease in people with IBS-type symptoms. Lactose intolerance can cause similar symptoms.

Laboratory testing

A clinician may order blood and stool tests to look for celiac disease, inflammation, infection and anemia. Celiac blood tests require you to be eating gluten to be accurate.

What our tests may reveal

  • Gut microbiome testing describes which microbes are present and in what proportions. It can be repeated over time.
  • Celiac genetics shows whether you carry the HLA variants associated with celiac disease. A negative result makes celiac disease very unlikely.
  • Lactose intolerance genetics shows whether you're genetically likely to keep producing lactase into adulthood.

Important limitations: None of these tests diagnoses IBS. Microbiome testing does not diagnose SIBO, infections, inflammatory bowel disease or any other condition. A celiac genetic test doesn't replace celiac blood tests or biopsy.
