It is not normal for a patient to have nose bleeding during pregnancy. It is caused by the dryness of the patient’s nasal mucosa, or low secretion function of the nasal mucosa, and may also be related to the overly dry environment in which the patient lives and works. There is also a possibility that the patient’s nose has been hit by an external force, resulting in the rupture of an arterial blood vessel in the nasal cavity, sometimes bleeding particularly heavily and appearing to bleed more than once. In terms of treatment, if the patient’s bleeding is relatively small, he can stop the bleeding at home by himself, pinching the bilateral noses with his hands and applying cold packs to the forehead or bilateral necks with ice packs. If necessary, the patient needs to go to the ENT department of the hospital so that the doctor can look for the bleeding point under the nasal endoscope and can consider performing anterior nostril filling or electrocoagulation treatment. Because caution should be exercised during pregnancy, the patient’s nose bleeding will improve significantly after aggressive treatment.
