What are the common causes of nose bleeding

Nosebleeds are common and not a serious problem. However, if you have frequent nosebleeds, you need to pay attention to it. Go to the hospital for a check-up to find out what is causing it. Never underestimate nosebleeds, as it may be a precursor to certain diseases or even the cause of cancer, so you must be careful. So what are the common causes of nosebleeds?

The first type: nasal mucosal rupture

This is the most common cause of nosebleeds and the main cause of habitual nosebleeds. Because there are three small blood vessels intersecting at the front of the nose near the nasal septum. These three small blood vessels are very fragile and are intertwined in a very shallow area on the skin surface. Although the blood vessels are small, if they are accidentally scratched, blood will continue to flow out.

Second, granulation inflammation inside the nose

Once the granuloma becomes inflamed, the nasal polyps will swell and become painful. Sinusitis, which is common, may also cause blood and pus to flow out if it is severe.

The third type: nasopharyngeal cancer

The bleeding location is internal bleeding at the back of the nasal cavity. This is a very serious disease and should not be taken lightly.

Fourth, viral or fungal infection:

Acute or chronic inflammation caused by damage to the nasal mucosa or submucosal tissue due to bacteria, fungi or irritants

Fifth, climate:

When the temperature changes greatly, whether it is sudden cold or sudden heat, it is easy to irritate the nasal mucosa and make you prone to acute or chronic rhinitis.
