What to watch with AMH and weight loss?

AMH (anti-Müllerian hormone) is a marker of ovarian reserve. In overweight women with PCOS, weight loss can lower AMH levels, reflecting improved hormonal balance. In normal-weight women without PCOS, the link is less clear – weight loss may even slightly reduce AMH, possibly due to caloric restriction. Importantly, AMH does not predict current fertility, only egg reserve. A sharp drop in AMH during a diet should not be automatically viewed as negative; it must be interpreted in the context of age, baseline value, and metabolic status. The evidence is mixed: studies show a positive effect of weight reduction on AMH in PCOS, but no clear recommendations exist for the general population. Consumers should be aware that self-initiated AMH testing without medical guidance can lead to misinterpretation. If pregnancy is planned, medical consultation is advisable.
