Nosebleeds are a relatively common occurrence in human life, especially more frequent in children. Some people believe that nosebleeds are a normal physiological phenomenon, while others think they are caused by an underlying illness. Through years of experimental research, the research team has proven that nosebleeds are not a normal condition, and several significant factors can lead to persistent nosebleeds.

case 1: Nasopharyngeal angiofibroma causing nosebleeds. This condition is not uncommon, particularly in children aged 14-15, and can even occur in those as young as 10. The earliest symptom is nosebleeds, often with significant blood loss. Besides nosebleeds, as the tumor grows larger, nasal congestion may also occur. This condition should be taken seriously by both parents and medical professionals. Due to the uniqueness of this disease, special considerations must be made during the diagnostic process.

case 2: Hypertension-induced nosebleeds. A crucial cause of nasal bleeding is related to high blood pressure, so it is essential to monitor the patient's blood pressure. Studies indicate that hypertension is a major cause of stroke, as elevated blood pressure can lead to hemorrhaging of blood vessels inside the skull. Similarly, external blood vessels can also rupture due to increased blood pressure, resulting in bleeding. Therefore, hypertension is an important cause of nosebleeds, and a warning sign of vascular damage caused by high blood pressure, which should be considered when treating nosebleeds. Uncontrolled or unstable blood pressure makes it difficult to manage bleeding, and even after control is achieved, other blood vessels may rupture, leading to further bleeding.

case 3: Tumors around the nose causing nosebleeds. Certain tumors near the nose can also lead to nosebleeds, particularly those in the brain and facial regions. Tumor-induced nosebleeds are characterized by blood-stained mucus due to tumor ulceration, rather than arterial rupture, and typically involve significant blood loss. Tumor ulceration results in frequent blood-stained nasal discharge, which occurs almost daily, unlike blood-stained mucus caused by infections, which clears up in a few days. Tumor-related bleeding tends to persist and worsen over time, with small amounts of blood each day. This can be an early indication of various tumors, requiring immediate medical attention, including nasal endoscopy to check for the presence of tumors in the nasal cavity.
