Why does the baby have yellow mucus in his nose when he has a cold?

It is normal for babies to have yellow nasal discharge when they have a cold. Generally, babies will have clear nasal discharge in the early stages of a cold. As the condition gradually improves, the nasal discharge will turn yellow and be relatively thicker. This indicates that the cold is gradually improving. At this time, you should pay more attention to conditioning and diet to avoid recurring colds. Let’s find out.

Why does the baby have yellow mucus in his nose when he has a cold?

The baby's clear nasal mucus turns into yellow nasal mucus. This is because in the case of bacterial or viral infection, the immune system launches a counterattack, and a large number of white blood cells rush to the infected site to kill the pathogens. After the battle, the remains of the pathogens and white blood cells are discharged into the nasal mucus, appearing yellow or green. If the yellow-green nasal discharge persists for about 10 days and there are no symptoms such as fever or headache, it may be a viral cold. Just keep waiting. It will usually heal on its own in about 10 days. If you have yellow-green nasal discharge accompanied by persistent fever, nausea, and headache, it may be sinusitis caused by bacterial infection and you need to go to the hospital for treatment.

The changes of baby's nasal discharge due to cold

1. Normal nasal mucus Normal nasal mucus is colorless and transparent and will not flow out of the nasal cavity. Its main components are water, as well as protein, carbohydrates and some desquamated cells. Causes of runny nose: Crying: When the baby cries, the mucus will increase and flow out of the nasal cavity. This is because tears flow into the nasal cavity through the nasolacrimal duct and turn into mucus before they are completely absorbed. Cold air stimulation: Parents living in the north should be well aware of this situation.

2. Abnormal nasal discharge 1. Continuous flow of clear nasal discharge ① In the early stage of a cold, clear watery nasal discharge continuously flows out of the nose. This situation is common in the early stage of a cold. This is because after catching a cold, the body wants to flush out the pathogens in the nasal cavity as quickly as possible, causing the nasal mucosa to become congested and swollen, secreting more mucus. Many people want to stop the runny nose as soon as possible when they see their baby has a runny nose. In fact, at this time, you should let the mucus flow out to expel the pathogens. ② Allergic rhinitis: If your baby has a runny nose with a lot of clear mucus, and is accompanied by sneezing, itchy nose and other symptoms, you should pay attention: Does your baby have allergic rhinitis? When you have allergic rhinitis, you have a lot of clear nasal discharge. In fact, it is the body's attempt to expel allergens from the nasal cavity as quickly as possible.
