Get medical help if arrange medical assessment when IBS-like or ongoing bowel symptoms occur with anemia, rectal bleeding, blood or black/tarry stool, or unexplained weight loss.
Self-care guide
Irritable bowel syndrome
A chronic disorder of gut-brain interaction causing recurrent abdominal pain with changes in stool frequency, stool form, or both, without visible structural damage explaining the symptoms.
Step 1 · First-line care
What to do first
IBS management should match the dominant bowel pattern and symptoms. Start with regular meals, adequate non-caffeinated fluids, physical activity, and individualized dietary review. Soluble fibre such as ispaghula/psyllium or oats is preferred when fibre is increased; bran and other insoluble fibre can worsen symptoms for some people. A low-FODMAP or other exclusion diet should be guided by a clinician or dietitian with relevant expertise. Gut-directed psychological therapies can be useful for persistent symptoms. Constipation- or diarrhea-targeted medicines and other clinician-directed IBS treatments have a larger role than herbs. Enteric-coated peppermint oil can be an optional short-term adjunct for global symptoms in adults.
Step 2 · Safety
When to get medical help
Extra caution: Children, pregnancy, older adults with new bowel symptoms, people with significant reflux/GERD or hiatal hernia, and people with inflammatory bowel disease, celiac disease, prior major GI surgery, or complex medication use need individualized assessment. Peppermint oil may worsen reflux and should not be generalized to inhaled, topical, or leaf preparations.

Peppermint Oil
Short-term relief of global IBS symptoms in adults using an oral enteric-coated peppermint-oil capsule comparable to studied products; not a claim for peppermint tea, leaf, food, aromatherapy, topical oil, or undiluted essential oil.
How it is used: Use only a labeled oral enteric-coated capsule intended for IBS-type gastrointestinal use. Do not substitute peppermint tea, food, inhalation, topical preparations, or homemade essential-oil capsules. Reassess if symptoms persist and address IBS subtype, diet, fibre, and other established therapies.
What does this evidence mean?
Enteric-coated peppermint-oil capsules may modestly improve IBS symptoms such as abdominal pain, bloating, and gas over the short term. Evidence quality is low and individual trials are mixed; long-term benefit has not been established.
Evidence may apply to one specific form of an ingredient — a capsule, extract, cream, or tea — and to a particular amount. Recipes and everyday foods may not match the form or amount that was studied.
