What is the Yellow Thing That Comes Out of My Mouth?

If you’re wondering what the yellow thing that comes out of your mouth is, you’re not alone. Many people experience this strange phenomenon, and there are a few possible explanations.

Causes of Yellow Discharge from the Mouth

Post-nasal drip: This is the most common cause of yellow discharge from the mouth. When you have a cold or allergies, mucus can build up in your nasal passages and throat. This mucus can then drain down the back of your throat and into your mouth, where it can mix with saliva and turn yellow.
Sinusitis: This is an infection of the sinuses, which are the air-filled cavities in your head. Sinusitis can cause a thick, yellow discharge that can drain down the back of your throat and into your mouth.
Bronchitis: This is an inflammation of the bronchial tubes, which are the airways that carry air to and from your lungs. Bronchitis can cause a yellow or green discharge that can be coughed up from your lungs and into your mouth.
Pneumonia: This is an infection of the lungs. Pneumonia can cause a thick, yellow or green discharge that can be coughed up from your lungs and into your mouth.
Cystic fibrosis: This is a genetic disorder that causes thick, sticky mucus to build up in the lungs and other organs. Cystic fibrosis can cause a yellow or green discharge that can be coughed up from the lungs and into the mouth.

When to See a Doctor

If you’re experiencing yellow discharge from your mouth, it’s important to see a doctor if you have any of the following symptoms:

Fever
Chills
Cough
Shortness of breath
Chest pain
Nausea
Vomiting
Diarrhea
Headache
Muscle aches
Joint pain

These symptoms can indicate a more serious medical condition, such as pneumonia or bronchitis. If you’re experiencing any of these symptoms, it’s important to see a doctor as soon as possible.

Treatment for Yellow Discharge from the Mouth

The treatment for yellow discharge from the mouth will depend on the underlying cause. If the cause is post-nasal drip, your doctor may recommend over-the-counter nasal decongestants or antihistamines. If the cause is sinusitis, your doctor may prescribe antibiotics. If the cause is bronchitis or pneumonia, your doctor may prescribe antibiotics or other medications to help clear up the infection.
