Our understanding of VMS is heating up

It’s not all about estrogen

Declining estrogen isn’t the only cause of Vasomotor Symptoms (VMS), also known as hot flashes and night sweats—we now know that VMS results from altered activity of the kisspeptin/neurokinin B/dynorphin (KNDy) neurons in the temperature control center of the hypothalamus.1,2

Watch how it works

VMS IN HER WORDS - It throws everything off kilter; [there are] no rules on when or why they [hot flashes] happen, they just happen.
