Causes of nose bleeding in children

When babies are at school, their physical constitution is very weak and they cannot compare with adults. Therefore, whether a child can grow up healthily depends on whether the parents can take care of the baby meticulously. Now I would like to ask every parent a question, do you know the reasons why children have nosebleeds? I think many people can’t answer this question. So today I will tell you the reasons why children have nosebleeds.

.reason

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 main causes of nosebleeds in children are:

1. Nosebleeds are prone 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, deviated nasal septum, nasal foreign bodies or nasal tumors.

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.

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

.Performance

When nosebleed occurs, blood usually flows out from the anterior nostril; or flows into the pharynx through the posterior nostril. When the amount of bleeding is large, both situations may occur at the same time. Sometimes nosebleeds flow into the throat, which may also manifest as "vomiting blood". This is because when nosebleeds are severe, more blood is swallowed, which irritates the stomach. In addition to causing abdominal pain, pale complexion, and sweating, it may also cause vomiting of coffee-like substances, that is, stomach acid reacts with blood, causing the blood to turn coffee-colored. If nosebleed is swallowed and discharged through the gastrointestinal tract, black stools may also occur. When the amount of bleeding is too heavy, it can cause hemorrhagic shock and endanger life. Long-term repeated bleeding can also cause anemia and blood diseases.

.deal with

Nosebleeds in children are an emergency and should be stopped promptly if they occur. A simple method is to plug the bleeding nostril with a sterilized cotton ball or pinch both nostrils with your thumb and index finger; you can also press the affected nostril with your index finger for 5-10 minutes to stop the bleeding. At this time, you should try to keep your child quiet and avoid crying. It is best to let the child sit with his head slightly tilted forward, and try to spit out the blood swallowed from the nasopharynx into the mouth. This will not only let you know the amount of bleeding but also avoid swallowing the nosebleed into the stomach, which will irritate the stomach and cause abdominal pain and vomiting. Send the child to the hospital for treatment as soon as possible.

There are many reasons for nosebleeds in children. If parents do not know the exact reason for their baby's nosebleed and give their children medicine indiscriminately, it is very likely that the baby's nosebleeds will increase in frequency and the bleeding will not be stopped. Therefore, it is very important for every parent to understand the reasons for their children's nosebleeds. Parents must remember what I taught today.
