At this time, you should go to the hospital for progesterone and sex hormone six tests to clarify the cause. After excluding other factors, you generally do not need to worry about it, and if necessary, you can take progesterone-containing drugs for treatment under the guidance of a professional doctor; 2. The patient should consider the possibility of polycystic ovary syndrome. In this case, B ultrasound, endocrine examination and laparoscopy should be performed to clarify the diagnosis. The disease is often caused by endocrine disorders and hormonal drugs should be taken as prescribed by the doctor in order to re-establish a normal menstrual cycle. During the treatment period, try not to eat too spicy food, such as chili peppers, etc., ensure balanced nutritional intake and maintain a good state of mind; 2. High mental stress: menstruation is affected by this factor. If patients have problems such as high academic pressure and poor family relations, they are prone to symptoms of irregular menstruation.
