Approximately what percentage of women experience VMS during menopause?

• A. Approximately 15%
• B. Approximately 25%
• C. Approximately 75%
• D. Approximately 90%

Answer: (C)

Vasomotor symptoms arise from hormonal changes that disrupt the body's thermoregulatory center, making hot flashes and night sweats the most common menopausal experience. Across many populations, about three-quarters of women report experiencing some vasomotor symptoms during the menopausal transition. This high prevalence reflects how widespread estrogen withdrawal is, though the exact percentage can vary with study design, definitions (anytime during transition vs. current symptoms), and the population studied. In short, roughly 75% is a widely used and reasonable estimate for how common vasomotor symptoms are in menopause.
