Menopause refers to the transition to menopause in women, now called perimenopause, during which hot flashes occur due to reduced estrogen levels in the body, autonomic dysfunction, and vasodilatory symptoms in the body. There are more than 400 kinds of estrogen receptors in women’s body, and almost all tissues and organs in the body are controlled and governed by estrogen. The typical symptoms are hot flashes and flushing. Perimenopausal hot flashes are a normal physiological process, and women can adapt to the process of estrogen level changes by adjusting their psychological state and living habits to smoothly pass this period. If the symptoms are more serious and affect normal work and life, it is recommended to go to the local hospital in time and take estrogen medication to relieve the symptoms under the guidance of a doctor.
