During which stage are Vasomotor Symptoms (VMS) more likely to occur?

Vasomotor Symptoms (VMS), such as hot flashes and night sweats, are particularly prevalent during the transitional phase of menopause known as perimenopause, which is represented in this context as Stage 1b. During this stage, hormonal fluctuations—specifically the decline in estrogen levels—are significant. This hormonal variability can lead to increased sensitivity of the thermoregulatory center in the hypothalamus, causing the hot flashes and associated symptoms experienced by many women.

In addition to hormonal changes, psychological factors, stress, and lifestyle choices can exacerbate VMS during this stage, making it a critical period for identifying and managing these symptoms. Understanding this timing is important for guiding treatment options, as interventions may be more effective when targeted at this specific transitional phase rather than at other stages when symptoms are less common or resolve. This emphasizes the significance of recognizing the unique characteristics of Stage 1b in relation to the manifestation of vasomotor symptoms in menopausal health care.
