Dr. Lu Cheng
Causes of nosebleeds in pregnant women may include the following aspects:
1. Hormonal changes: During pregnancy, increased estrogen levels cause blood vessels in the nasal passages to dilate, making the nasal mucosa more sensitive and fragile, thus leading to nosebleeds more easily. This is due to the increased risk of bleeding caused by vascular dilation.
2. Nasal dryness: Hormonal changes during pregnancy may increase nasal secretions. Improper handling of these secretions may irritate the nasal mucosa and cause bleeding. In addition, dry air can worsen this condition, causing dryness and cracking of the nasal lining, resulting in bleeding.
3. Nasal inflammation: Pregnant women may suffer from rhinitis or sinusitis, which can make the nasal mucosa fragile and increase the likelihood of bleeding.
4. Mechanical injury: Habits such as nose picking or trauma from external force may cause physical damage to the nasal cavity, leading to nosebleeds.
5. Increased metabolism: The accelerated metabolism and increased blood circulation in pregnant women can raise the pressure on nasal blood vessels, resulting in bleeding.
