The exact timing of menopause in women varies widely among individuals, but in general, it occurs mostly between the ages of 45 and 55. Menopause, also known as perimenopause, is the physiological phase before and after the natural menopause in women. Due to the decline of ovarian function, the level of female sex hormones decreases significantly, resulting in a series of physiological, psychological and psychiatric changes, mainly dysfunction of the autonomic nervous system, called menopausal syndrome. It mainly includes menstrual disorders, hot flashes and sweating, chest tightness and shortness of breath, change of temperament, anxiety and suspiciousness, insomnia and dreaminess. Most women can go through menopause smoothly through self-regulation; however, there are still a few women with more serious symptoms that affect their normal life and require treatment to go through it. In addition, besides menopausal syndrome, the drastic hormonal changes also pose a risk of many diseases for menopausal women, such as hypertension, hyperlipidemia, obesity, osteoporosis and osteoarthrosis. Therefore, it is recommended that menopausal women have annual medical checkups to keep an eye on their changes and prevent diseases from occurring. Menopause is a normal physiological change for women, and although the exact timing and duration of menopause varies from woman to woman, it is a natural stage that every woman must go through. As long as you stay positive and optimistic, accept your changes, and pay attention to your health, you will almost always pass through it smoothly and safely.
