Effect of Body Mass Index on Menopausal Symptoms

Women with higher body mass index (BMI), especially over 27, are more likely to experience hot flashes, night sweats, and other menopausal symptoms. Surprisingly, excess body fat seems to worsen menopausal symptoms despite its association with estrogen production. The Swan study highlighted the correlation between BMI and these symptoms, with weight loss interventions leading to significant improvements in hot flashes, emphasizing the role of lifestyle in managing menopausal discomfort.
