Why would someone get heavy nose bleeds every day for a week and then none for a few months and than heavy again?

Frequent heavy nosebleeds can be caused by various factors, including dry air, Allergies, or nasal irritants, which may lead to the drying and cracking of nasal membranes. Certain medical conditions, such as hypertension or blood clotting disorders, could also contribute to recurring episodes. If nosebleeds are persistent or severe, it's essential to consult a healthcare professional to rule out any underlying issues. Seasonal changes or fluctuations in environmental conditions may explain the intermittent nature of the bleeding.
