The Real Cause of a Constantly Phlegmy Throat (or Mucus)
- Upper respiratory infection (URI): This is the most common cause of a phlegmy throat. URIs are caused by viruses, such as the common cold or the flu. They can also be caused by bacteria, such as strep throat.
- Allergies: Allergies can cause the lining of your nose and throat to become swollen and produce mucus. Common allergens include pollen, dust, and animal dander.
- Postnasal drip: This is a condition where mucus from your nose and sinuses drips down the back of your throat. It can be caused by a URI, allergies, or acid reflux.
- Chronic obstructive pulmonary disease (COPD): This is a group of lung diseases that includes chronic bronchitis and emphysema. COPD can cause excess mucus production and a phlegmy cough.
- Asthma: This is a chronic condition that affects the airways. Asthma can cause inflammation and narrowing of the airways, which can lead to mucus production and a phlegmy cough.
- Smoking: Smoking irritates the lining of the airways and can lead to excess mucus production.
- Dehydration: When you’re dehydrated, your mucus becomes thick and sticky, which can make it more difficult to cough up.
- Certain medications: Some medications, such as ACE inhibitors and angiotensin receptor blockers, can cause excess mucus production.
If you have a constantly phlegmy throat, it’s important to see a doctor to determine the cause. The treatment will depend on the underlying condition. For example, if you have a URI, your doctor may prescribe over-the-counter medications, such as decongestants and cough suppressants. If you have allergies, your doctor may recommend allergy medications, such as antihistamines and nasal sprays. If you have postnasal drip, your doctor may prescribe an over-the-counter decongestant or a nasal spray. If you have COPD, your doctor may prescribe medication to help open your airways. If you have asthma, your doctor may prescribe medication to control your asthma symptoms. If you smoke, quitting smoking is the best way to reduce mucus production.
If you have a constantly phlegmy throat, there are also some things you can do at home to help relieve your symptoms:
- Drink plenty of fluids. This will help thin the mucus and make it easier to cough up.
- Use a humidifier or take a hot shower. This can help loosen the mucus and make it easier to cough up.
- Gargle with salt water. This can help soothe a sore throat and loosen mucus.
- Avoid smoking and secondhand smoke.
- Get plenty of rest.
If your symptoms are severe or don’t improve after a few days, see your doctor.
