was sind kohlenhydrate — when to see a doctor?

Carbohydrates are macronutrients including sugars, starches, and fiber. They are the body's primary energy source. When to see a doctor? If you experience persistent symptoms such as unexplained weight loss, excessive thirst, frequent urination, fatigue, or digestive issues (e.g., bloating, diarrhea after carb-rich meals), consult a physician. These may indicate metabolic disorders like diabetes, insulin resistance, or intolerances (e.g., lactose intolerance, fructose malabsorption). Also seek medical advice if you have risk factors such as obesity or a family history of metabolic disease. A blood glucose or HbA1c test can provide initial clues. Evidence is based on clinical practice; individual symptoms are not specific. Caveat: home tests (e.g., blood glucose monitors) are screening tools, not diagnostic. Always confirm abnormal results with a doctor.
