   "Do you have any ideas?"

   Hearing Teacher Xin\'s question, Xie Wanying lowered her head and asked the patient a question: "When did your period come? Is it coming now?"

   Hearing the student\'s suspicious direction, Xin Yanjun immediately reacted and asked the patient\'s friend, "Is her period normal?"

   "She mentioned before that she has had less menstrual periods recently, probably because she was busy with work, and wanted to find some medicine to take some conditioning." The patient\'s friend remembered the patient\'s personal mention of this, and said.

   "So, during the period of abnormal menstruation, she had a nosebleed, didn\'t she?"

   "She occasionally suffers from nosebleeds. She said it\'s normal. The climate here is relatively dry." The patient\'s friend said that they felt that the doctor asked some questions that made them wonder.

   A group of medical staff wanted to stare at these people: I asked if there were any symptoms of the patient\'s illness, but they insisted that they did not.

  Have you had nosebleeds before?

   In the perception of the common people, they may not think that an occasional nosebleed is a disease.

  Nosebleeds are very common in the population. Some cities have a bad climate and are relatively dry, which leads to dry nasal passages. In addition, it is autumn, which belongs to the season of dry weather. If the patient himself has bad habits such as picking his nose, it can often cause a small amount of nosebleeds. This small amount of nosebleed is not in the way and can be stopped by itself without medication and other measures.

   A little nosebleed is nothing to be afraid of. The problem is that more than one place on your body sends out a signal for help. It can’t be called just a little nosebleed.

   It can only be said that ordinary people are not like doctors who have learned systematic medical knowledge. When thinking about the abnormality of the patient\'s body, they should combine all the symptoms of the patient\'s body to judge. The human body is a whole, and judging diseases cannot be divided. For some diseases, the symptoms often seem to be unrelated to the cause.

   "What? Is her nosebleed related to her menstruation?" The patient\'s friend heard what the doctor meant and asked in surprise.

   Unheard of, what is the relationship between menstruation and nosebleeds for girls?

   is really related, the relationship is quite big.

  There is a medical term called compensatory menstruation. Some people call it ectopic menstruation, which refers to periodic non-uterine bleeding similar to menstruation.

  The medical term needs to be dismembered and analyzed. First of all, the periodicity of this bleeding is synchronized with menstruation, which may appear before menstruation or during menstruation.

  Secondly, the site of occurrence is not in the uterus, so it is called non-uterine bleeding. So where does it happen? It happens in the nasal mucosa, external auditory canal, breast, gastrointestinal tract, bladder, etc.

   So strange? Why didn\'t the uterus bleed, and went to these places to bleed? A disease has multiple etiologies that require detailed analysis.

  First of all, the most common symptom of such patients is epistaxis, which can account for one-third of the cases.

   How does compensatory menstrual epistaxis come about? Speaking of the relevant anatomical knowledge first, the main part of epistaxis is the front and lower part of the nasal septum, where there is a rich capillary network. Small blood vessels are fragile and bleed easily. It happens that the epithelial cells here are very sensitive to estrogen and can be affected and stimulated by estrogen, causing it to undergo periodic congestion and swelling like the endometrium. When estrogen levels plummet, periodic bleeding like the uterus may occur.
