The reasons why patients have nosebleed symptoms once they eat chili include nasal mucosa damage, etc., as follows: 1. Damage to the nasal mucosa: often because the nasal mucosa is eroded and broken, and has not been effectively treated and improved. After eating chili peppers, the strong irritating factors will easily cause the nasal mucosa to become eroded and congested, causing the blood vessels under the nasal mucosa to break down, resulting in nosebleed symptoms, and also causing the nasal mucosa blood vessels to dilate, further increasing the chances of nosebleed. 2, other: some patients may also have obvious deviation of the nasal septum, or the nasal cavity may have hemangiomas, bleeding polyps and other bleeding-prone growths. If necessary, further detailed examination is needed to distinguish the cause. For patients with nosebleeds, they need to avoid spicy, stimulating and fire-prone foods, and can eat more cool vegetables and fruits.
