Frequent nosebleeds in the elderly are mostly related to nasal vascular sclerosis, nasal inflammation, tumor and other factors, which need to be examined by nasal endoscopy, nasal CT or MRI. 1. The nasal cavity of the elderly is prone to vascular sclerosis, especially when accompanied by hypertension or diabetes and other diseases, when affected by external forces, it is easy to trigger spontaneous rupture of blood vessels in the nasal cavity, resulting in severe bleeding in the nasal cavity. 2. Inflammatory stimulation of nasal mucosa by rhinitis and sinusitis will trigger the vascular erosion and breakage in the nasal cavity, which will lead to bleeding phenomenon, accompanied by nasal congestion, runny nose, headache and other symptoms. 3. Tumor in the nasal cavity can easily trigger the necrosis of the nasal mucosa, causing the rupture of blood vessels in the mucosa and trigger bleeding, which can be accompanied by pain in the nasal cavity, numbness, nasal congestion, headache, and enlarged lymph nodes in the neck. If you have frequent nosebleeds, you need to go to the ENT department to get a clear diagnosis through nasal endoscopy, CT or MRI, and then follow the doctor’s instructions for treatment.
