was ist kohlenhydrate — when to see a doctor?

Carbohydrates are macronutrients that provide energy. You should see a doctor if you experience unexplained weight changes, persistent fatigue, excessive thirst, frequent urination, or intense sugar cravings – these may indicate impaired glucose tolerance or diabetes. Also consult a physician if you suspect carbohydrate malabsorption (e.g., lactose intolerance) with bloating, diarrhea, or abdominal pain after eating. For existing metabolic conditions like diabetes or metabolic syndrome, regular medical follow-up is essential. Note: This information is not a substitute for medical advice. A doctor can use fasting blood glucose, HbA1c, and clinical history to determine if treatment is needed. The evidence is based on clinical practice and guidelines, not on the DNA tests mentioned in the context.
