What to watch with VKORC1 and Abnehmen?

VKORC1 encodes the vitamin K epoxide reductase, a key enzyme in blood clotting. The well-studied variant rs9923231 (-1639G>A) affects warfarin sensitivity: carriers of the A allele (T in forward strand, ~39 % in Europeans) typically require lower doses. Regarding weight loss (Abnehmen), the link is indirect but clinically relevant. If you are on warfarin or other vitamin K antagonists, any change in diet—especially in vitamin K-rich foods like green leafy vegetables—can alter your INR. Weight loss itself can change drug distribution and metabolism, potentially requiring dose adjustments. The evidence for VKORC1 and warfarin dosing is human-strong (multiple clinical guidelines). However, there is no direct evidence that VKORC1 variants affect weight loss success or metabolism. Caution: a consumer DNA test for VKORC1 alone is not sufficient for clinical decisions. Always consult your doctor before starting a weight loss program if you take anticoagulants. Regular INR monitoring is essential.
