haben bananen ballaststoffe — when to see a doctor?

Yes, bananas contain dietary fiber, primarily soluble fiber like pectin. The amount depends on ripeness: green bananas are higher in resistant starch (a prebiotic), while ripe bananas have more soluble fiber. You should see a doctor if you experience persistent digestive issues after eating bananas—such as bloating, diarrhea, or constipation—which could indicate fructose malabsorption, irritable bowel syndrome, or an intolerance. Also seek medical evaluation for unexplained abdominal pain, unintentional weight loss, or blood in stool. For most people, banana fiber is well tolerated, but those with inflammatory bowel disease (e.g., Crohn’s) may need to adjust intake.
