Most nosebleeds in pregnant women are caused by ruptured capillaries in the nasal cavity, but may also be caused by dry nasal mucosa, deviated nasal septum, nasal hemangioma or hypertension, coagulation dysfunction, etc. Physical methods are mainly used to stop the bleeding. If a pregnant woman has a nosebleed, it is recommended to stop the activity and stay seated, avoid lying down or tilting the head, so as not to cause the blood to flow back into the throat. After promptly removing the blood clots from the nasal cavity, pinch both sides of the nose with your hands and compress for about 10-15 minutes, while using a cold water bag or wet towel on the nose, neck and cheeks to induce vasoconstriction to reduce bleeding and stop the bleeding. When a pregnant woman has a nosebleed, she can stuff a small piece of sterilized gauze or cotton in each nostril, paying attention to avoid using irritating liquids, otherwise it will easily cause discomfort to the nasal cavity. If the bleeding does not stop after applying the above methods, it is recommended to visit the otorhinolaryngology head and neck surgery department of the hospital, and if necessary, nasal endoscopy is feasible to find the bleeding point for electrocoagulation to stop bleeding. In addition, pregnant women should pay attention to maintain a light taste in their daily diet and eat less hot, fried or spicy food to avoid aggravating nosebleeds, and pay attention to keep the humidity in the room appropriate, and apply humidifiers appropriately.
