Can Pharmakogenetik Medicheck help with Müdigkeit?

Pharmacogenetics (e.g., Medicheck) analyzes genetic variants affecting drug metabolism. For fatigue, it can be relevant if the cause is suboptimal medication response or side effects – e.g., with antidepressants, beta-blockers, or thyroid hormones. However, fatigue is multifactorial: poor sleep, stress, diet, inactivity, or underlying diseases are more common. The genetic test does not diagnose fatigue directly; it only suggests possible dose adjustments. Evidence is mixed: strong for some drugs (CYP2D6, CYP2C19), weak for others. Important: Do not self-medicate; discuss results with a physician. MyBody-X offers such tests, but clinical utility for general fatigue is limited. Caveat: Most variants have small effect sizes; lifestyle and medical workup take priority.
