Perimenopausal menstrual disorders are mainly related to the decline of ovarian function. The perimenopausal period can last up to 10 years in women. After the age of 37, the ovarian function can gradually decline and the estrogen level in the body then decreases, which can lead to symptoms of menstrual disorders. In women, the main symptoms are shortened menstrual cycle, incomplete menstrual flow, sporadic menstruation and prolonged menstrual cycle, which may even lead to ovulation disorder and infertility. When ovulation promotion treatment is given, the follicles do not develop well to the point of slow growth. Severe ovarian failure may result in amenorrhea and even menopausal symptoms. Some women may also experience significant skin dryness, breast atrophy and sagging, insomnia, and excessive dreaming. Ultrasound should be done to rule out any thickening or uneven echogenicity of the endometrium and, if necessary, diagnostic scraping or hysteroscopy to rule out endometrial cancer, especially in patients with obesity, diabetes and hypertension. If endometrial lesions are ruled out, hormone replacement therapy can be performed under the guidance of a gynecologist, but contraindications to hormone use need to be ruled out, and regular review of uterine ultrasound, cervical cancer smear and breast examination should be noted. Usually, ovarian function cannot be reversed, but before the age of 45, you can delay the decline of ovarian function through basic methods, such as adjusting your lifestyle, developing good daily habits, going to bed early, waking up early, exercising, maintaining a healthy and optimistic attitude, while not being too busy at work, not being too stressed, not being in a state of excessive anxiety, paying attention to your diet, eating more fresh fruits and vegetables Pay attention to the supplementation of high-quality protein.
