Patients with Irritable Bowel Syndrome (IBS) can eat dragon fruit. They should consume more fruits that are rich in vitamins and fiber, but they must avoid fruits that are too sour, too sweet, or too spicy. Patients with Irritable Bowel Syndrome should also eat on a regular schedule and maintain a fresh and clean diet, while eliminating anxiety and nervousness. For patients with IBS, consider using anti-anxiety medications and medications that regulate the gut, such as fluoxetine and mebeverine, cautiously. (Please use medication under the guidance of a doctor.)
