What role does TSH play in Blutzucker?

TSH (thyroid-stimulating hormone) regulates thyroid hormone production, which in turn affects glucose metabolism. Elevated TSH (hypothyroidism) can reduce insulin sensitivity and increase hepatic glucose output, contributing to higher blood sugar levels. Conversely, low TSH (hyperthyroidism) can accelerate glucose uptake in peripheral tissues and predispose to hypoglycemia. However, the association between TSH and blood sugar is indirect and modulated by many factors such as body weight, inflammation, and medications. Direct causal effects are difficult to isolate in individuals. The evidence is based on physiological studies and clinical observations, not on randomized controlled trials. A TSH test alone is not a reliable predictor of blood sugar issues; it should be interpreted together with fT3, fT4, insulin, and glucose. MyBody-X does not directly measure TSH, but thyroid-related genetic markers (e.g., PDE8B, FOXE1) can influence individual TSH set points. Caveat: effect sizes are small, and lifestyle factors dominate.
