Introduction
A patient who is seven months pregnant suddenly experiences epistaxis (nosebleed). The specific causes are as follows: 1. Pathological causes: The most direct cause of epistaxis at seven months’ gestation is rupture of local nasal mucosa or submucosal blood vessels, leading to nosebleed. Patients are often affected by dryness of the nasal mucosa, or by a dry, polluted ambient air environment, which can easily induce nasal mucosal congestion and dryness.

During pregnancy, women commonly experience various physiological changes. After conception, a pregnant woman’s immune function typically declines. Moreover, the nutrients absorbed by the mother must support both herself and the developing fetus; thus, even minor lapses in self-care may trigger symptoms such as epistaxis (nosebleeds). So, what causes nosebleeds during the seventh month of pregnancy?

What Causes Nosebleeds During the Seventh Month of Pregnancy?

Sudden epistaxis occurring in the seventh month of pregnancy may stem from several underlying factors:

1. Pathological causes: The most direct cause of epistaxis at this stage is rupture of local nasal mucosal or submucosal blood vessels. Pregnant women are particularly susceptible to nasal mucosal dryness—often exacerbated by ambient environmental factors such as low humidity or air pollution—which can lead to mucosal congestion, drying, erosion, ulceration, and subsequent bleeding.

2. Physiological causes: Epistaxis may also result from insufficient fluid intake, habitual nose-picking or nose-rubbing, or inadequate vitamin intake.

Additionally, some pregnant women may develop elevated blood pressure—a potential contributor to epistaxis. If clinically indicated, further comprehensive evaluation is warranted. During pregnancy, immunosuppression is common. Prolonged consumption of fried foods or exposure to dry air may induce “heatiness” (a traditional Chinese medicine concept describing inflammatory or hypermetabolic states), often accompanied by symptoms such as dry mouth or sore throat. Drinking rock sugar–steamed pear soup may help alleviate these symptoms. We hope this information proves helpful!
