What are the effects of early menopause on the body

Patient's question:

Menopausal since 1998, the cause is unclear, nor do I understand

Doctor's answer:

Analysis of the condition: Generally, in our country, the average age for rural women is around 46-47, while in urban areas, it might be slightly later, around 50, due to better nutrition. This is the typical normal age for menopause.
Guidance: When women enter menopause, ovarian function begins to decline. First, the corpus luteum function progressively weakens. Follicles develop only to a certain extent and then atrophy on their own, no longer ovulating. Without corpus luteum formation, fertility declines. However, in the early stages of ovarian decline, follicle-stimulating hormone (FSH) secretion increases, while luteinizing hormone (LH) remains at normal levels. Due to the body's natural adjustment of sexual function, FSH can return to normal levels, resulting in ovulatory menstrual cycles. As a result, some women who have been infertile for many years may suddenly conceive during the premenopausal period.
As age increases, ovarian function becomes unstable and then declines, leading to imbalances. This often manifests as irregular menstruation, menstrual cycle disorders, prolonged periods, and continuous bleeding before menopause. Meanwhile, symptoms such as premenstrual tension syndrome, cyclic breast pain, edema, and headaches may disappear.
