was hat kohlenhydrate — when to see a doctor?

When to see a doctor about carbohydrates depends on persistent or severe symptoms. Carbohydrates are a primary energy source, but issues arise when the body cannot metabolize them properly. Consult a doctor if you experience: chronic fatigue after meals, unexplained weight changes, excessive thirst and frequent urination (possible diabetes), recurrent digestive issues like bloating, diarrhea, or constipation after carb-rich foods, and intense cravings or brain fog. Even if a DNA test (e.g., MyBody-X) suggests 'carb sensitivity,' this is not a diagnosis. The effect sizes of common SNPs are small, and evidence for diet-type predictions is weak (marketing/unclear). Focus on clinical markers like blood glucose, HbA1c, and symptoms. A physician can evaluate for conditions such as insulin resistance, lactose intolerance, or fructose malabsorption. Safety note: Drastic carb restriction (e.g., keto) without medical supervision may lead to nutrient deficiencies or thyroid issues in some individuals. Evidence: human-strong for general medical guidelines, but weak for DNA-based carb advice.
