Common questions in this guide

How is irritable bowel syndrome (IBS) diagnosed?
Doctors use a modern approach called a positive diagnosis, often relying on the Rome IV criteria. They evaluate your specific symptoms and may run tests to rule out other conditions that mimic IBS before confirming your diagnosis.
Can other conditions mimic the symptoms of IBS?
Yes, several other health conditions can perfectly mimic irritable bowel syndrome. These include Bile Acid Malabsorption (BAM), Small Intestinal Bacterial Overgrowth (SIBO), and Celiac disease.
Why is tracking my stool important for managing IBS?
Tracking your stool using tools like the Bristol scale helps categorize your specific IBS subtype. Knowing whether you struggle more with diarrhea, constipation, or a mix of both is essential for your doctor to prescribe the most effective treatments.
What should I do if first-line IBS treatments do not work?
If foundational treatments do not provide enough relief, you and your doctor can discuss a step-by-step plan for advanced therapies. There are many guideline-backed medications available tailored to your specific IBS subtype.

Questions to Ask Your Doctor

  2. 2.What is our step-by-step plan if the foundational first-line treatments do not provide enough relief?
  3. 3.Are there specific IBS-mimicking conditions, like Bile Acid Malabsorption or Celiac disease, that we need to test for before confirming my diagnosis?
