Constant phlegm or a feeling of mucus stuck in the throat is common, but it isn’t a diagnosis by itself. Your nose, sinuses, throat and lungs naturally produce mucus; the problem is usually that mucus is being produced in excess, becoming thicker, or draining where you notice it.

The most common causes
1. Postnasal drip
Mucus from the nose or sinuses drains down the back of the throat. Allergies, colds, sinus problems, dry air and some medications can contribute. Typical clues are frequent throat-clearing, a sensation of drainage, hoarseness or a cough that’s worse at night.

2. Allergies
Pollen, dust mites, mold and animal dander can trigger excess mucus. You may also have sneezing, nasal congestion or itchy/watery eyes.

3. Acid reflux/GERD
Reflux can irritate the throat and create a persistent sensation of mucus or a lump, sometimes without classic heartburn. Hoarseness and chronic cough can occur as well.

4. Irritants
Cigarette smoke, secondhand smoke, air pollution, dust and chemical fumes can irritate the airways and increase mucus.

5. Dehydration and dry air
When secretions become thicker, mucus can feel much more noticeable and difficult to clear.
6. Respiratory infections
A cold, flu, bronchitis or sinus infection can temporarily increase mucus. Importantly, yellow or green mucus alone doesn’t prove that you have a bacterial infection.

What you can try
Drink enough water so your urine is generally pale; fluids help thin secretions.

Try a saline nasal spray or rinse if you have nasal congestion or postnasal drainage.

A cool-mist humidifier can help when dry air is contributing; clean it regularly.

Warm liquids can soothe an irritated throat.
Avoid cigarette smoke and other obvious respiratory irritants.
If allergies seem responsible, reducing exposure and using an appropriate allergy treatment may help.
