Nosebleed

A nosebleed, medically known as epistaxis, is a common occurrence where bleeding arises from the nasal cavity. It often results from the rupture of tiny blood vessels within the mucous membranes that line the nose. Nosebleeds can be categorized into two types, anterior and posterior. Anterior nosebleeds, the most prevalent, originate from the front part of the nose and often involve the septum, particularly Kisselbach's plexus, a region with a rich blood vessel supply. Meanwhile, posterior nosebleeds, less common but potentially more severe, originate nearer to the back of the nasal passage and may require medical intervention.

The causes of nosebleeds can vary from minor to serious. They often result from local trauma, such as nose picking or injury, but can also be prompted by environmental factors like dry air or irritation from allergies. Systemic factors, such as blood clotting disorders, hypertension, or the impact of certain medications, can also lead to nosebleeds. While most nosebleeds resolve spontaneously or with simple first aid measures such as pinching the nose and leaning forward, recurrent or severe episodes warrant medical evaluation to exclude underlying pathological conditions or the need for treatments such as cautery or nasal packing.
