How To Get Rid Of Excess Phlegm In Your Throat

Do you have excess phlegm stuck in your throat? Have you been frequently clearing your throat and you can’t seem to get that sticky stuff off your throat because it keeps building back up? 

You may clear your throat often because it feels like something is tickling or stuck in your throat. You may have these sensations even when there is nothing there. If you do, that may be mucus in your throat.

Differences between mucus and phlegm

Mucus is a normal, slippery substance that is produced by many lining tissues in your body. It forms a protective lining in certain parts of your body, keeping them from drying. 

It is found in the membranes that line your:

  • nose
  • sinuses
  • mouth
  • throat
  • lungs

Mucus also contains antibodies that help your body to develop immunity and fight infection. It helps your body by defending those linings against invaders such as bacteria and viruses. When you are healthy, your body produces about 1 to 1.5 liters of mucus every day. 

You may often mistake mucus for saliva, but the two substances are not the same. Saliva is a fluid produced in your mouth that helps you to break down and swallow the food you eat. 

Mucus, on the other hand, contains dead cells and debris that are collected from your upper and lower respiratory tracts. The mucus traps these and any microorganisms, such as bacteria, so that you can cough them up and clear your lungs.

Causes of excess phlegm

While mucus is beneficial to your body, excess mucus production can have bad consequences. This is especially if the excess phlegm is uncleared and chronic. 

The resulting consequences you may have from having excess phlegm include breathing difficulties and increased risk of infection. It will usually take a mere bad cold, an allergy, or contact with something irritating to throw your body’s mucus production into overdrive. 

When you get sick with an upper respiratory infection, a cold, or allergies, the mucus secreted by your respiratory tract becomes sticky, thicker, and denser.  At that point, it is called phlegm (1).

What is phlegm?

Phlegm is a type of mucus that is produced in your lower respiratory tract and lungs. It becomes more noticeable when you have an acute sickness or you have a longstanding illness (2).  

You may find it harder to clear phlegm out of your airways (your nose, sinuses, and lungs). This is because it is so much thicker than mucus.  

When you’re sick with certain illnesses, phlegm noticeably hangs around in the back of your throat. Sometimes, that’s when you’ll notice it. 

Phlegm is one of your body’s ways of collecting and getting rid of bacteria in your respiratory tract. It may drip down from your nose and sinuses, get coughed up from your lower airway, or accumulate in your throat.

Both phlegm and mucus are actually totally normal bodily products.  You need mucus regularly because of its protective and support functions (1). 

Your mucus membranes make phlegm to protect and support your respiratory system. This helps your body to trap dust, allergens, and viruses. When you’re healthy, the mucus produced is thin and less noticeable. 

If you’re sick or exposed to foreign particles or allergens, your phlegm can get thick. It becomes more noticeable as it traps these foreign substances.

Phlegm is a healthy part of your respiratory system. However, if it’s making you uncomfortable, you may want to find ways to thin it or remove it from your body. A healthy body requires some mucus, but too much phlegm can be very uncomfortable and annoying. 

Lifestyle risk factors 

Excess phlegm may be caused by:

  • allergies
  • outdoor air pollution
  • indoor air particles such as dust or pet hair
  • smoking tobacco products or secondhand smoking
  • infections, such as the common cold or flu
  • irritation of your nose, throat, or lungs
  • a lung disease, such as chronic obstructive pulmonary disease (COPD), pneumonia, lung cancer, or cystic fibrosis.
  • digestive conditions, such as gastroesophageal reflux disease (GERD).

How to eliminate excess phlegm and mucus

Stay Hydrated

Drink plenty of fluids to stay hydrated and keep your mucus thin. When you’re sick with a cold, drinking extra fluids can thin your mucus and help your sinuses to drain.

If you suffer from seasonal allergies, staying hydrated will help you to avoid being congested.

Gargle with salt water

Gargling with salt water can help soothe your irritated throat and clear away residual mucus. Add one teaspoon of salt in a glass of warm water and gargle. Do this several times a day.

Avoid alcohol and caffeine. They can cause dehydration.

Both caffeine and alcohol can lead to dehydration if you consume them in excess. When you’re trying to get rid of excess phlegm and mucus, you should drink plenty of warm water and other warm non-caffeinated beverages.

Take hot showers or hot baths

Spending time in a steam-filled bathroom will help to loosen and clear mucus and excess phlegm from your nose and throat. When you allow hot water to pulse on your face, this can also bring you relief from sinus pressure.

Keep moist air around you

When dry air irritates your nose and throat, it causes more mucus to form. This increases your phlegm production. 

To avoid this from occurring, place a cool-mist humidifier in your bedroom.  A humidifier will help you sleep better, keep your nose clear, and prevent a sore throat.

Keep your head elevated

If you have a buildup of mucus and excess phlegm and it’s bothersome, it may help if you sleep propped up on a few pillows. You may also find a reclining chair more comfortable than lying flat to sleep. 

Lying flat will increase your discomfort. When you lay like that, you’ll feel the excess phlegm collecting at the back of your throat.

Use a saline nasal spray or rinse

A saline spray or nasal irrigator will help clear out mucus, excess phlegm, and allergens from your nose and sinuses. You should use sterile sprays that contain only sodium chloride. 

If it’s your baby who’s having congestion from phlegm, you should get sterile saline mist for newborns.

Inhale through a damp washcloth 

Applying a warm, wet washcloth to your face and inhaling through it is a quick way to return moisture to your nose and throat. The heat will help to relieve your pain and pressure.

Avoid smoking

Avoid smoking

You should not smoke and must avoid secondhand smoke as well. Smoking and secondhand smoke will cause your body to produce more mucus and excess phlegm. 

Use eucalyptus oil

Apply eucalyptus oil directly to your chest. This will help subdue your coughs and reduce excess phlegm. You can also add a few drops of eucalyptus oil to a diffuser or a warm bath to help clear your nose.

Avoid known irritants

You should avoid fragrances, chemicals, and pollution which can irritate your nose, throat, and lower airways. These irritants cause your body to produce more mucus.

Avoiding any foods that cause acid reflux

If you’re prone to heartburn, you probably know the trigger foods that aggravate your acid reflux. You should avoid such foods because acid reflux can lead to excess phlegm and mucus production. 

Keep track of your reactions to food

Do you have any foods which cause reactions that mimic seasonal allergies? Such foods may cause your nose to run and your throat to itch, leading to excess phlegm. You should keep a record of any foods that trigger an increase in your phlegm production.

Take over-the-counter medication

What is the best over-the-counter (OTC) medication that you can take for excess phlegm in your throat? The best way for you to relieve excess mucus in your throat is to take an expectorant. 

Guaifenesin is an over-the-counter expectorant. Medicines containing Guaifenesin will help thin and loosen excess mucus in your throat. These medicines get the mucus moving again, making coughs more effective.

You may try an over-the-counter medication like Mucinex. This expectorant will help to thin mucus and excess phlegm stuck in your throat, making it easier for you to cough and spit it out. 

Avoid Suppressants

You should avoid over-the-counter suppressants like Robitussin which are designed to suppress your cough. You may be tempted to use suppressants because you’re experiencing a nagging cough with excess phlegm. 

However, coughing is your body’s way of keeping secretions out of your throat and lungs. Generally, you should use cough syrups sparingly, if at all (3).

Minimize the use of decongestants

Decongestants are good for drying your secretions and alleviating your runny nose. However, they may make it harder for you to get rid of excess phlegm and mucus.

You should avoid taking decongestants for excess phlegm.

Cough it up, spit it out

When excess phlegm rises from your lungs into your throat, your body is trying to remove the phlegm. It is healthier for you to spit it out than swallowing it.

When to see a doctor

Many of the times that you have excess phlegm, it may be due to some minor illnesses. These illnesses are best left to run their course.

Occasionally, when you have excess phlegm and mucus, it may indicate a more serious condition. You should see a doctor if you have excess phlegm and mucus that is severe, persistent, or does not improve with rest and home remedies.

  1. Thanks for sharing this, I’m going to try out gargling salt water. I have a steroid nose spray because I have this problem. This is under prescription though.

  2. I agree that the nasal irrigation is really helpful, though I’ve only used it when really congested. The other home remedy that i learned growing up is hot honey and lemon – it works well for me.

  3. Good, informative article on mucus and phlegm. I like how you noted the differences, but also the benefits of how these throat situations run their course as the body’s defense.
