wie viele gene hat der mensch — when to see a doctor?

This question combines two distinct topics: the number of human genes and when to see a doctor for digestive issues. According to current scientific consensus, humans have approximately 20,000 to 25,000 protein-coding genes, established by the Human Genome Project. Additionally, thousands of non-coding RNA genes and regulatory elements exist, making the total functional units higher. This is well-supported evidence (human-strong). For bloating and gas after meals, you should see a doctor if symptoms persist longer than two weeks, are accompanied by severe pain, diarrhea, constipation, or unintentional weight loss. Immediate medical attention is needed for blood in stool or nighttime symptoms. The context notes that home tests for food intolerances are often unreliable; clinical diagnostics (lactose breath test, IgE panels) are the standard. Nutrient deficiencies can mimic intolerance symptoms, so a clinical workup is essential. The MyBody-X Longevity DNA test analyzes over 170 gene variants but cannot diagnose acute digestive complaints. Evidence for doctor visit: practice.
