If you have persistent cough, shortness of breath, fever, or blood in your phlegm, you should see a doctor immediately. Reducing spicy and sour foods and eating two hours before bedtime can help reduce phlegm due to acid reflux.
The following reasons may be behind phlegm that does not go away even after coughing and spitting:
1. Post-Nasal Drip
This is a condition in which excess mucus produced in the nose or sinuses flows down the back of the throat. This is common in people with allergies and sinusitis.
2. Acid Reflux (GERD/LPR)
This is a condition in which stomach acid travels up the esophagus and reaches the throat. This causes discomfort in the throat and the body produces more mucus as a defense.
3. Allergies
Allergies to dust mites, pollen, and pet dander cause inflammation in the airways and increase mucus production.
4. Smoking
Toxins build up in the lungs and throat of smokers. The body constantly produces mucus to expel them (Smoker’s Cough).
5. Respiratory infections
People with bronchitis or chronic asthma may have narrowed airways and mucus buildup.
6. Lack of water intake
When the body is dehydrated, mucus becomes thick and sticks to the throat. This can be difficult to expel.
Things you can do at home to reduce mucus:
Gargle with salt water: Gargling with lukewarm salt water three times a day can help loosen mucus.
Steam: Steaming with water mixed with eucalyptus oil can help open up the airways.
Drink plenty of water: Drinking lukewarm water can help thin out phlegm.
Honey and ginger: Mixing a spoonful of honey with ginger juice can help reduce throat infections.
