Magen-Darm-Gesundheit: what are common causes?

Common causes of gastrointestinal issues are diverse. They include dietary factors such as low fiber intake, high-fat meals, or excessive sugar. Infections from bacteria (e.g., Helicobacter pylori), viruses, or parasites are frequent triggers. Medications like NSAIDs or antibiotics can disrupt gut flora. Food intolerances (lactose, fructose, gluten) and chronic inflammatory bowel diseases (Crohn's disease, ulcerative colitis) are also common. Stress and psychological strain affect the gut-brain axis and can worsen symptoms like bloating or diarrhea. The provided context focuses on genetic tests (e.g., ADH1B, VDR FokI) and their limitations, not directly on general causes. Genetic factors may play a minor role but are rarely the primary cause. A balanced diet, adequate hydration, exercise, and stress management are key to supporting gut health. Persistent symptoms warrant medical evaluation.
