There is yellow green snot in the nose, why is the snot green?

When the cold virus invades the human body from the respiratory tract and causes a cold, the virus moves in the nasal cavity, causing the nasal mucosa to swell, and the nasal cavity will produce more secretions, and the extra water and mucus can help expel the dead virus or necrotic tissue from the body. If the previously clear nasal discharge turns yellow, it means that the nasal passages may be infected by bacteria or other viruses, and there will be yellowish-green purulent discharge. At the same time, the clear nasal discharge becomes viscous nasal discharge, which may be acute rhinitis caused by a cold.

In addition to colds, sinusitis may occur if it is accompanied by pain and discomfort in the nasal mucosa. If the nasal discharge is long-term yellow and purulent with nasal congestion, it may be due to chronic inflammatory changes. Some people may have a foul-smelling purulent discharge, which can be caused by atrophic rhinitis.

The appearance of yellowish-green nasal discharge at the beginning of a cold is a symbol of wind-heat cold. If a cold patient changes from a clear nose to a yellow purulent nasal discharge, it manifests as cold and heat. Yellow pus nasal discharge indicates that the patient has heat in the body, and the more yellow the color, the more severe the inflammation.

However, a runny nose should also be seen in two. If the runny nose starts out and then turns yellow-green, the amount of nasal discharge decreases and the nasal passages become dryer, indicating that the cold is gradually getting better. If the amount of nasal discharge does not decrease, the yellowish-green nasal discharge becomes heavier and heavier, which is a sign that the cold is getting worse.

In fact, the runny nose when you have a cold should also be judged according to the specific situation of the patient, and it is not correct to say that when you see a yellow-green runny nose, you think that the cold has gotten better, so you stop taking medicine. Yellow-green nasal discharge does not mean that the cold will be cured, and you must not be careless, because it is easy to induce chronic rhinitis or sinusitis. It is necessary to use antibiotics for a long time for chronic **, and it is necessary to establish a correct understanding so as not to delay the condition and make the symptoms of cold, rhinitis and sinusitis more aggravated.

If the patient is now experiencing a yellowish-green nasal discharge, it may be caused by rhinitis. Patients should go to the hospital in time for a detailed examination to determine whether rhinitis is present. Since the patient may have a runny nose, there is blood in the nasal discharge.

A purulent discharge is a bacterial infection that can be treated with antibiotics**.

The yellowish-green nasal discharge may be a nasal infection or sinus infection, and there are many conditions that can cause infection, such as ethmoid sinusitis and nasal foreign body with infection. Nasal foreign body with infection: The appearance of yellowish-green nasal discharge is accompanied by nasal foul odor.

Polyp necrosis or malignancy may cause yellowish-green purulent nasal discharge. In this case, it is advisable to seek medical attention promptly. During the ** period, the diet should be light and eat fruits and vegetables in moderation, which is conducive to the recovery of the disease.

The yellowish-green turn of the nose is usually caused by a cold or rhinitis caused by an increase in bacteria. Because nasal secretions are divided into aqueous and purulent, watery discharges can form white boogers, while purulent secretions may form yellow boogers. Secretions evaporate and dust or other granular substances accumulate in the air to form granular or clumpy boogers.

Bacterial infections in the nasal cavity produce purulent discharge, and when water evaporates, yellowish-green boogers form.

The yellowish-green nasal discharge is more common in rhinitis, the acute attack of sinusitis. Rhinitis, sinusitis patients in the acute attack of the nasal mucosa swelling is obvious, the secretion increases, and the nasal discharge increases and is yellowish-green.

In this case, it is recommended to go to the regular hospital otolaryngology department for treatment, and take active measures, generally can use sensitive antibiotics orally, play the role of anti-inflammatory, analgesic, swelling, and at the same time can also use Chinese patent medicine for symptomatic purposes. You can take some heat-clearing and detoxifying, dampness-dispelling Chinese patent medicines, such as Huoqi pills and so on.

It belongs to the heat cold and flu, there is fire in the body, dry heat,

The difference in the color of the nasal discharge is due to the different bacteria infecting, yellow is generally Staphylococcus aureus infection, and green is generally Pseudomonas aeruginosa infection.

The inner surface of the nasal cavity of healthy people is lined with a complete layer of mucosa, on which there are many goblet cells with secretory function, and there are mucous glands under the mucosa, which usually carry out secretory activities, and the secreted water is used to moisten and inhale air, in addition, the mucus glands often secrete a small amount of mucus, which is evenly distributed on the surface of the mucosa. Adsorption of dust and microorganisms inhaled into the air. Mucus also contains lysozyme, which has the ability to inhibit and dissolve bacteria.

This mucus is snot.

Normal nasal discharge is colorless and transparent, which is also known as clear nasal discharge. When you have a cold, your nose will clear at first, and then your nose will become thicker and white. The next one may be a thick, green runny nose, especially if a secondary bacterial infection develops.

This is so because it contains a large number of neutrophils. Neutrophils, although they belong to white blood cells, are green. When the immune system detects that a pathogen has invaded the body, it begins to mobilize troops, and neutrophils are sent by the bloodstream, but they run outside the blood vessels to fight.

It is a phagocytic cell, and its combat mode is to "eat" bacteria into it and kill pathogens with various ** in the cell. One is the release of hypochlorous acid, a disinfectant to bacteria.

Hypochlorous acid is produced by neutrophils within myeloperoxidase, which has a structure in common with chlorophyll in that it contains a dihydroporphyl ring, a special structure that determines their color: green. Therefore, the thick nasal discharge will be green because it contains a lot of neutrophils, which in turn contain a lot of green myeloperoxidase.
