At the Root
Hormonal Weight Gain
Not the same as gaining weight from overeating. Usually a shift in how the body uses and stores energy.
Your Concerns
What Is It?
Hormonal weight gain is not the same as gaining weight from overeating. It usually reflects a shift in how the body uses and stores energy — driven by changes in insulin sensitivity, cortisol, thyroid function, and sex hormones. For many patients in their late 30s onwards, the changes accumulate quietly until the same diet and exercise routine stops producing the same outcome. At 23MD, hormonal weight gain is investigated through bloodwork and a clinical conversation before any plan is written.
