The participants practiced yoga for 40 to 90 minutes, 1 to 3 times per week, for periods ranging from 6 weeks to 8 months. The control groups received education, exercise, probiotics, or the usual care (diet advice, medical follow-up assessments, and medications as needed).

Yoga did not lead to greater improvements in IBS symptoms such as bloating, diarrhea, abdominal pain, or the effect of symptoms on daily life, compared to the controls. It also did not improve mental health outcomes, including anxiety, depression, or quality of life.

The quality of evidence was low.
