Constant phlegm or a feeling of mucus in the throat can have several causes. It’s often not the mucus itself that’s the primary problem, but an underlying condition.
Common causes include:
- Postnasal drip: Mucus from the nose and sinuses drains down the back of the throat, often due to allergies, colds, or sinus inflammation.
- Acid reflux: Stomach acid reaching the throat (sometimes called laryngopharyngeal reflux) can cause throat irritation and excess mucus.
- Allergies: Environmental allergens such as pollen, dust mites, or pet dander can increase mucus production.
- Respiratory infections: Colds, flu, and other infections can temporarily increase mucus.
- Smoking or exposure to irritants: Tobacco smoke, pollution, and certain workplace exposures can irritate the airways.
- Asthma: Some people with asthma experience chronic mucus production and throat clearing.
- Dehydration: Thickened mucus can feel more noticeable when you’re not drinking enough fluids.
Ways that may help:
- Drink adequate fluids to keep mucus thinner.
- Treat underlying allergies if present.
- Use saline nasal rinses for postnasal drip.
- Avoid smoking and other airway irritants.
- If reflux is suspected, avoid large meals before bedtime and discuss treatment options with a healthcare professional.
Seek medical evaluation if symptoms persist for weeks, worsen, are accompanied by unexplained weight loss, difficulty swallowing, coughing up blood, or significant breathing problems.
If you’d like, describe your symptoms (how long you’ve had them, whether you have heartburn, allergies, a cough, smoking history, etc.), and I can help narrow down the most likely causes.
