Causes of nosebleeds in children

Especially in summer, children are particularly prone to nosebleeds, because the temperature in summer is very high, and children generally do not want to eat vegetables, which will lead to dryness, resulting in nosebleeds. Or they may like to pick their nostrils, which will also cause nosebleeds. Let us take a look at the reasons why children love nosebleeds.

1) Dry rhinitis: It is the most common cause in children. It is usually caused by dry nasal mucosa and increased vascular fragility, which leads to bleeding during defecation, sneezing, and sleep. Most of them are caused by improper diet, such as not eating vegetables and drinking less water. It accounts for more than 90% clinically.

2) Foreign objects in the nasal cavity or picking the nose: Children aged 2 to 5 years old like to pick their noses with their hands, or put various foreign objects into the nasal cavity, which often causes nose bleeding. In this case, the amount of bleeding is less, but it is also a very common clinical phenomenon.

3) Nasal trauma: This is also a common cause of disease in children. Children are more active and more prone to accidents than adults. The nose is a relatively fragile part of the face. Once injured, it can cause nosebleeds, which can be quite serious and involve a large amount of bleeding. In addition, iatrogenic trauma, such as endoscopic sinus surgery, can easily cause fractures of the ethmoid or sphenoid bones, leading to bleeding, hematoma, etc. if the operation is not performed properly because children have a smaller field of vision.

4) Acute and chronic inflammation of the nose: Generally speaking, children's rhinitis and sinusitis are much milder than those in adults, with a shorter course of illness and refractory rhinitis. Therefore, nosebleeds caused solely by rhinitis are rare and of relatively mild severity.

5) Nasal tumors: In childhood, malignant tumors of the nasal cavity and paranasal sinuses are extremely rare, but nose bleeding is often the first symptom. Among benign tumors, nasopharyngeal angiofibroma is the most common cause of nosebleeds, which is more common in male adolescents around 8-20 years old. The bleeding is heavy, recurrent and prolonged, and ultimately requires surgical resection. Nasal hemangiomas can also cause varying degrees of nosebleeds and often require surgical treatment.

This article tells us the reasons why children often have nosebleeds. If this happens, you still need to go to the hospital for comprehensive treatment, because repeated nosebleeds are not normal. Children are prone to become nervous when they have nosebleeds, and some sedatives can be used.
