Current evidence on the therapeutic use of fiber in irritable bowel syndrome.

Abstract in brief

• Patients with irritable bowel syndrome (IBS) often turn to natural fiber products for symptom relief due to limited effectiveness and tolerability of traditional medications.
• Recent scientific studies highlight ispaghula husk, a soluble fiber, as a recommended first-line treatment for IBS, whereas insoluble fibers like wheat bran are less effective.
• Although prebiotics such as fructooligosaccharides and galactooligosaccharides may help improve IBS symptoms, the current evidence is inconclusive, and further research is needed to confirm their benefits.]
