The snot is yellow-green

Normally, a runny nose is caused by illness or crying. However, when crying, the snot is usually clear. If the runny nose is caused by illness, the snot usually has a different color. In fact, different snot colors indicate different health conditions. Some people have yellow snot, and some have yellow-green snot. So why is the snot usually yellow-green?

Early stage of cold, allergic rhinitis: colorless and odorless clear nasal discharge

Transparent snot is what we ordinary people often call "clear snot". This kind of snot is generally colorless, thin and odorless. Its composition is water-like liquid. This situation occurs in the early stage of a cold, and the patient will experience symptoms of sneezing and runny nose.

The symptoms of patients in the early stages of a cold are similar to those of allergic rhinitis. At this time, there is no bacterial infection in the nose and antibiotics are generally not required.

If you have chronic allergic rhinitis, it is best to go to the hospital for an allergen test and stay away from allergens after identifying the cause. If the disease occurs seasonally, you can use some anti-allergic drugs in advance, at least a week in advance.

Milky white and yellow snot: You have to be careful

If your nose starts to itch, you start to sneeze, and your mucus is runny and sticky, this could be related to sinusitis. The mucus becomes thick and sticky, forming a milky white and sticky state, which is a manifestation of chronic sinusitis. If it is sticky and yellow, it is an acute attack of chronic sinusitis or a manifestation of acute sinusitis, which may be a bacterial infection.

Some patients occasionally discharge yellow water when they lower their heads or sneeze. This is acute sinusitis caused by sinus cysts or maxillary sinus cysts, or an acute attack of chronic sinusitis. At this time, antibiotics and nasal sprays are needed; for yellow water sinus cysts, surgical treatment is recommended.

Green snot: The situation is a bit serious

Green snot is more serious than yellow snot. The appearance of green snot indicates that the bacteria are stronger and the human immune cells are at a disadvantage in the "battle". Therefore, it is recommended to go to the hospital to see a doctor as soon as possible, who can take symptomatic medication to relieve the symptoms.

Bloody nasal discharge: Damage to the nasal mucosa

When you have a cold, the nasal mucosa is very fragile. If you blow your nose hard, it is likely to cause the small blood vessels on the nasal mucosa to rupture, and your nasal mucus will naturally be bloody. This situation is more common among the elderly and children. If children's nasal mucosa is dry, they may experience nasal bleeding; when the blood pressure of the elderly rises, nasal mucosal erosion may also cause blood.

Black snot: Don’t panic! It’s not actually caused by a disease

Nowadays, many cities have smog days, and many citizens have encountered this situation: when they get off the car to go to the vegetable market to buy vegetables, they feel uncomfortable in their nose when they get on the car again, and after blowing their nose, there is black sticky substance. Don't panic, this may be caused by the smog weather!

Because when we breathe, the tiny dust and smoke particles in the air enter the nasal cavity and mix with the mucus to appear as black mucus. Once there is smog, remember to wear a mask when going out.
