Perimenopause causes menstrual disorders can be regulated by lifestyle modification or medication, and it is important to choose the right medication according to the specific situation and to keep the body under observation at all times. Perimenopause is the physiological stage before and after menopause, if the symptoms are not obvious, such as low menstrual flow, long menstrual cycle, etc., this situation generally does not affect the health of the body, and can be relieved through lifestyle modification, more outdoor exercise, maintain a good mood, ensure adequate sleep, balanced nutritional intake, and pay attention to personal hygiene. However, if the menstrual period lasts for a long time and the menstrual dribbling is not complete, you can use drugs such as metacycline to stop bleeding, or you can use hormonal drug treatment, such as estradiol, nil estradiol and other drug treatment. Perimenopausal menstrual disorders should be treated with close attention to endometrial lesions, because during perimenopause, the level of progesterone in the body decreases, which can easily cause endometrial lesions, so if menstruation is irregular for a long period of time, it is necessary to carry out a detailed examination to observe whether there is any thickening of the endometrial lining or uneven echogenicity, and so on. Therefore, when menstrual disorders occur in the perimenopausal period, it is recommended to consult a doctor in a timely manner, complete the relevant examinations, clarify the cause of the disease under the guidance of a professional doctor, and provide symptomatic treatment. All of the above medications should be used under the guidance of a doctor, avoid self-medication.
