When you do not come to the hospital for your period, you need to register with the gynecology or obstetrics and gynecology department. If your period is delayed for less than a week, you do not need to visit the hospital. For women of childbearing age, first of all, to exclude pregnancy, you can take morning urine and test with pregnancy test strips. Secondly, endocrine disorders such as hyperadrenocorticism, chronic diseases such as anemia, tuberculosis, nephritis and diabetes, as well as ovarian cysts and ovarian dysplasia, can cause menstrual failure, and these need to be diagnosed in the hospital with relevant tests. In addition, you can go to the hospital to have an ultrasound of the uterine adnexa, measure the thickness of the endometrium, and have your blood hormone level tested to find out the cause of your menstrual failure and use menstrual regulating drugs under the guidance of your doctor. In addition to the treatment after clarifying the cause, pay attention not to stay up late and not to work too hard in daily life. Develop good habits, relax, and exercise properly to enhance your physical fitness and facilitate regular menstrual flow.
