Higher Body Mass Index (BMI) causally increases GDF15 plasma levels, identifying BMI as a driver of GDF15 elevation rather than the reverse.

High GDF15 is a consequence of higher body weight, not the cause. Managing BMI is the primary lever; GDF15 levels will naturally decrease as metabolic stress is reduced.

GoodSupportsMEDIUM confidence
Using reverse MR, we identified a potential causal association of body mass index on GDF15 (IVW pFDR=0.0072).

Why this rating

Reverse Mendelian Randomization in large cohorts supports the causal link, though sensitivity analyses showed some pleiotropy.
