Baby's nose bleeds in the middle of the night

If your baby has a nose bleed in the middle of the night, there are actually many reasons for the condition. Parents must make a judgment based on the actual situation of their baby. If it is a nasal injury, you need to go to the hospital for treatment in time, because this may be caused by systemic factors. When the climate deteriorates, it will also induce this situation, and even weather changes can cause an attack.

There are many reasons for nosebleeds in children. Generally speaking, children under 2 years old rarely have nosebleeds because the capillary network in the nasal cavity of children of this age is not fully developed. The site of nosebleeds in children is mostly in the capillary network area in the front of the bilateral nasal septum, also called the Li area. This vascular network is very superficial and distributed in the mucosal layer of the nasal septum.

The causes of nose bleeding in children mainly include local factors and systemic factors.

Local factors:

1. Nosebleeds are more likely to occur when the nasal mucosa is dry, the capillaries are dilated, there is nasal inflammation or irritation, such as various rhinitis, sinusitis, nasal tuberculosis, nasal syphilis, nasal trauma, nasal septum deviation, nasal foreign bodies or nasal tumors, etc.

2. Poor climatic conditions, such as dry air, heat, low air pressure, cold weather, and high room temperature can cause nosebleeds.

3. Some children have the bad habit of picking their noses with their hands. When the nasal mucosa is dry, it is easy to pick their noses and cause bleeding.

4. Bad habits such as being picky about food, eating a partial diet, and not eating vegetables can also cause nosebleeds due to vitamin deficiency.

Systemic factors include:

1) Blood disease: It is one of the common systemic factors causing nosebleeds in children. Such as hemophilia, leukemia, thrombocytopenic purpura, aplastic anemia, etc. Childhood is a period when blood diseases are prone to occur, and nosebleed is often the first symptom. Therefore, patients with recurrent nosebleeds should undergo blood screening, such as routine blood tests, to avoid missed diagnosis.

2) Acute febrile diseases: including viral upper respiratory tract infections, hemorrhagic fever, measles, etc., which are mainly caused by high fever causing vascular and nerve dysfunction and capillary rupture causing bleeding.

3) Nutritional disorders or vitamin deficiencies: such as vitamin C, K, and P deficiencies. Vitamin C is closely related to vascular permeability; vitamin K is related to the formation of prothrombin, and its deficiency can cause nosebleeds. In children, long-term picky eating is the main cause of nutritional disorders and trace element deficiencies.

4) Systemic chronic diseases: such as hypertension, liver and kidney dysfunction, etc., will affect coagulation function, but are relatively rare in children.

5) Genetic diseases: more common in children, such as hereditary telangiectasia and Osler's disease, which are autosomal genetic diseases.

At the same time, certain systemic diseases such as fever, hypertension, arteriosclerosis, leukemia, thrombocytopenic purpura, aplastic anemia, etc. can also cause nose bleeding.
