Irritable Bowel Syndrome

Related Terms:

IBS

Irritable bowel syndrome (IBS) is a chronic disorder of the colon. For unknown reasons, the colon acts in an abnormal way. It often causes cramps, bloating, abdominal pain, and changes in bowel movements. People with IBS may experience predominately diarrhea, predominately constipation, or a mix of both.

There is no cure for IBS. Treatment is often a combination of steps that may help to manage the symptoms. Options include changes to diet and activity, counseling, a variety of medications, and probiotics. Since symptoms tend to naturally fluctuate, it can take some time to find the best treatment and needs may change over time.

Natural Therapies

Alternative therapies may be an additional step to help manage symptoms.

Likely Effective

  • Probiotics —Used to help restore a healthy balance of beneficial bacteria or yeast in the colon. Look for Bifidobacterium bifidum MIMBb75 (adults) and Lactobacillus rhamnosus GG (children). Other strains may be helpful as well. The probiotics used should contain at least one billion colony-forming units per daily dose.A1-A5
  • Peppermint (enteric coated)—Appears to reduce muscular spasms in the colon, which helps ease abdominal symptoms.B1-B6
    • Note: Peppermint oil is safe when taken as directed, but can be toxic at high or excessive doses
  • Hypnotherapy —Involves deep relaxation and focus. Attention may be directed to the gut. It appears to work better in people with IBS that is unresponsive to other treatments.C1-C6

Possibly Effective

  • Yoga —Appears to be more effective in reducing stress and anxiety than easing IBS symptoms in adolescents and young adults.D1-D2
  • Relaxation therapy , including mindfulness mediationE1-E5
  • Acupuncture —When added to other treatments.F1-F4
