What Does Green Mucus Mean?

Mucus, or snot, is an important part of our body’s defense mechanism, helping to protect us from infections and irritants. When it’s healthy, mucus has a clear, white or light yellow color. But when an infection occurs, it can change to a variety of colors, including green. So what does green mucus mean?

Causes of Green Mucus

The most common cause of green mucus is a viral or bacterial infection. When the body produces more mucus to fight an infection, it can take on a green hue. Infections of the sinuses, throat and lungs are common causes of green mucus, as are those of the ear, nose and throat.

In rare cases, green mucus can indicate a serious infection like pulmonary edema, which is a condition in which the alveoli, or air sacs, in the lungs fill with fluid. Other serious infections associated with green mucus can include abscesses, pneumonia and empyema.

Treating Green Mucus

If you’re experiencing green mucus, it’s best to see your doctor for a full diagnosis. Depending on the underlying cause, your doctor may prescribe antibiotics, decongestants or other medications.

You can also try some home remedies to help you get relief from green mucus. These include:

• Drinking lots of water throughout the day

• Taking steamy showers

• Doing nasal rinses with warm water and salt

• Using a saline nasal spray

• Eating foods or taking supplements that are rich in potassium, vitamin C, zinc, iron and other essential vitamins and minerals

• Taking a cough suppressant

• Doing breathing exercises

• Avoiding smoke, dust and other allergens

Bottom Line

Green mucus may indicate a viral or bacterial infection, or even a more serious condition like pulmonary edema. It’s important to contact your doctor to get a proper diagnosis and treatment. You can also try some home remedies to help you get relief from green mucus.
