Yellow sno

Controlling the color of mucus, both in adults and children, is very important, as it is a clear sign of the disease you are suffering from. In the case of yellow snot , the most likely thing is that you have a superinfection and your body is fighting to prevent it. There are different possible scenarios in relation to the color of the mucus: white, yellow, greenish, reddish, brown, black and transparent.

Under normal conditions, mucus is not very solid or very liquid, so it stays in the nose. The fact that they are sticky is because the particles of contamination or microorganisms get stuck to them. Thus, their original white color can take on different shades depending on the substance that adheres to them.

What is mucus and why is it produced?

The main function of mucus is to protect the respiratory system from external agents: microorganisms , pollution, allergens, etc. It acts in a similar way to a spider web, trapping any type of agent of this type. Then, the cilia of the epithelial cells are responsible for dragging them out in the form of mucus.

This substance is made up mostly of water . In addition, it contains a mixture of different lipids, mucopolysaccharides, immunoglobins and glycoproteins. Mucus is generated by epithelial cells in the respiratory system.

It is completely normal to have mucus on a daily basis since this substance acts as a defensive barrier. The problem comes when the amount is higher than usual, the mucus becomes too thick, or changes color.

The importance of snot color

Snot can be classified based on color. When it is not white, it means that there is an infection in the body. When this infection is mild, its color is yellowish.

Meanwhile, yellow mucus responds to a stronger microbial attack. When the hue is greenish, the infection is even more powerful. And if the mucus is black, it may be due to a yeast infection.

  • Transparent – Mucus is usually clear in color. However, sometimes it can also be a symptom of illnesses such as colds.
  • Yellow: when this substance is yellow in color, it means that the body is fighting an infection.
  • Brown – Brown mucus is a dead giveaway that the body has cleared the airways of substances such as tar, nicotine, or dust.
  • Reddish: if the mucus is reddish in color, it indicates that there is traces of blood in it. It is not uncommon when the nasal mucosa becomes inflamed due to a cold. If these mucus are accompanied by bloody phlegm, it is necessary to see a doctor.
  • Black: As for black mucus, it usually occurs after inhaling smoke in a fire or after spending a long period of time in heavily polluted cities.

What is yellow snot?

The reason why this substance turns yellow is due to the high content of white blood cells , which are responsible for fighting the microorganisms of the infection.

White blood cells are responsible for fighting and eliminating microorganisms and bacteria to deal with the infection. The yellow color in the nasal discharge also indicates that the body is in the process of healing . The safest thing is that after two or a maximum of three weeks the snot will return to being transparent and, in addition, they will appear in less quantity.

If the yellow mucus is accompanied by phlegm when coughing, this substance is another signal of the body’s defense system to expel harmful agents.

Bronchitis is what inflammation of the bronchi is called . The bronchi are the tubes in charge of transporting air both to and from the lungs. With inflammation, the amount of air that enters and leaves the lungs is less. That is why one of the most common symptoms of this disease is the expulsion of phlegm.
