Why do I get nosebleeds during pregnancy?

Nosebleeds in pregnancy surprise women who never had them before, and the explanation is vascular: pregnancy increases your total blood volume substantially, and hormones dilate blood vessels everywhere - including the tiny, fragile vessels lining the nose. The NHS confirms nosebleeds are common in pregnancy and usually harmless, annoying rather than dangerous. Dry air, colds, allergies, and nose-blowing add the local trigger. Stopping one correctly: sit down and lean forward - not back, which sends blood down the throat - pinch the soft part of the nose firmly for a full 10 to 15 minutes without checking, and breathe through your mouth. A cold cloth on the nose helps. Prevention: a dab of petroleum jelly or saline spray inside the nostrils against dryness, a humidifier in winter, and gentle nose-blowing. When to call: nosebleeds that are heavy, that keep recurring despite the technique, or that come with other bleeding like bleeding gums - worth mentioning at a prenatal visit, since clotting can be checked. And a nosebleed with severe headache, vision changes, or sudden swelling in the second half of pregnancy belongs to the preeclampsia warning cluster - that combination is a same-day call, not a nose problem. High blood pressure in pregnancy makes nosebleeds more likely, which is the link. Pymander is a free AI doctor, 24/7 by text.
