What should I know about wie merkt man das mit dem darm was nicht stimmt?

Recognizing gut issues is a common concern, but symptoms are often nonspecific. Key signs include persistent bloating, gas, abdominal pain, diarrhea, constipation, or alternating bowel habits. Fatigue, skin issues, and food intolerances can also be linked to gut dysfunction. However, these symptoms overlap with irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), infections, or simple dietary triggers. Direct-to-consumer genetic tests (e.g., MTHFR, VDR, FTO) are sometimes marketed for gut health, but the evidence for actionable insights is weak. No genetic test can diagnose a gut disorder. The standard medical approach includes stool tests, breath tests for lactose/fructose intolerance, and colonoscopy when indicated. Self-tracking of symptoms and triggers (food diary) is helpful, but professional evaluation is crucial—especially for red flags like blood in stool, unexplained weight loss, or severe pain. In summary: pay attention to persistent changes, but rely on clinical assessment rather than unvalidated tests. Evidence-based diagnosis requires a doctor’s input, not a DNA kit.
