Low menstrual flow with blood clots may be a normal phenomenon, or it may be related to endocrine disorders, cold and so on. 1. Normal phenomenon: If the current menstrual flow is low and there is no abnormality in the past, it may be a normal phenomenon, and you need to pay attention to the next menstrual situation. 2. Endocrine disorders: If a woman has been working under pressure, studying hard or has gynecological endocrine diseases such as polycystic ovary syndrome or premature ovarian failure, due to endocrine disorders, the patient will have irregular ovulation or no ovulation, and the endometrium can not be completely stripped off, which will lead to a low menstrual flow, and if the blood can not be discharged in a timely manner, this will lead to the appearance of clots. 3. Cold: If the patient is cold and drinks cold or gets cold in the rain before menstruation, it may lead to poor menstrual blood flow, resulting in low menstrual flow and blood clots, and some women may suffer from chills and abdominal pain at the same time. For women with low menstrual flow and blood clots, it is recommended that they go to the gynecology department of a regular hospital to improve ultrasound, sex hormones and other relevant examinations, and then take active treatment under the guidance of the doctor after clarifying the cause of the disease.
