Nosebleed in pregnant women at night

Epistaxis (nosebleeds) in pregnant women during the night may be caused by improper diet, malnutrition, nasal mucosal injury, allergic rhinitis, or gestational hypertension. Pregnant women should identify the specific underlying causes and adopt appropriate measures to improve or treat the condition.

1. Improper Diet

Pregnant women who consume spicy or irritating foods and fail to replenish fluids promptly may experience dryness in the nasal cavity, leading to rupture of capillaries and subsequent nosebleeds. This can be improved by increasing fluid intake and enhancing indoor humidity.

2. Malnutrition

Inadequate nutrient intake during pregnancy may lead to malnutrition, which affects capillary permeability and fragility, potentially causing nocturnal epistaxis. It is recommended to improve nutritional intake; if necessary, supplement calcium, iron, zinc, and other nutrients under medical guidance.

3. Nasal Mucosal Injury

The nasal mucosa and capillaries may become damaged due to repeated scratching, excessive pressure, or traumatic impact, resulting in pathological changes such as tissue rupture and bleeding. For mild cases, physical hemostasis methods such as nasal packing or nasal compression can be used. For severe cases, medications such as vitamin K1 injection, thrombin lyophilized powder, or povidone-iodine solution may be used under medical supervision to promote hemostasis and prevent infection.

4. Allergic Rhinitis

During sleep, if a pregnant woman is exposed to specific allergens such as chemical fumes or pollen, a non-specific immune response in the nasal cavity may be triggered. This can cause abnormal dilation of submucosal capillaries and even rupture-induced bleeding, leading to symptoms such as epistaxis, nasal congestion, and runny nose. If these symptoms occur, antiallergic treatment with medications such as loratadine capsules, biyanining granules, or ditong nasal spray may be used under medical guidance.

5. Gestational Hypertension

Elevated blood pressure may cause dilation of capillaries in the nasal mucosa, making them prone to rupture and bleeding. Applying a cool compress with a cold towel may help; if necessary, antihypertensive medications such as nifedipine controlled-release tablets, amlodipine besylate tablets, or labetalol hydrochloride tablets may be used under a doctor’s supervision.

If symptoms recur frequently or progressively worsen, prompt medical evaluation at a hospital is advised for thorough examination and early intervention. During treatment, it is important to drink plenty of water to maintain hydration and follow a light diet, which can help reduce the frequency of nosebleeds.
