What Is A Wet Cough?

Coughing is your body’s way of clearing out irritants like dust, pollutants, toxins, fluid, or pathogens from your airway. A wet cough, also known as a productive cough, is a condition where the presence of irritants like dust, allergen, smoke, excess mucus, etc. in your airway triggers your coughing reflex and you get phlegm (mucous) in your mouth (1). The mucous membrane lining your respiratory system produces mucus to keep your airways moist and prevent irritants from entering your lungs.

A wet cough may indicate that your body is producing more mucus than usual which is being pushed out of your lungs, throat, nose, or airway. A wet cough may either be acute or chronic (2).

• Acute wet cough typically lasts less than 3 weeks.

• Chronic wet cough may last longer than 8 weeks and 4 weeks in adults and children respectively.

Quick Tip

Practice pursed-lip breathing to improve lung function. Inhale through your nose for two counts, and exhale slowly through pursed lips for four counts.

Wet Cough: Possible Causes

Respiratory Infection

You may develop a wet cough in response to a respiratory infection that your body is trying to fight off. Some common infections that lead to excessive mucus production include common cold or flu, pneumonia, and acute bronchitis. Respiratory infections that lead to a wet cough may also produce other symptoms like (3):

• sore throat
• fatigue
• fever
• chills
• chest and nasal congestion
• runny nose
• body ache

Bronchiectasis

Bronchiectasis is a medical condition affecting the bronchi (or the tubes that carry air to and from the lungs). In this case, the bronchial tubes are widened and scarred due to prolonged inflammation. Thicker walls cause mucus to accumulate in the air passages as the walls are now not strong enough to make mucus move out of the lungs. This triggers a wet cough. In addition, cilia (thin hair-like strands inside bronchi) are destroyed thus worsening the condition. You may notice one or more of the following symptoms accompanying your wet cough if you have bronchiectasis (4):

• breathlessness
• wheezing
• fatigue
• blood or blood-stained mucus with cough
• chest pain
• clubbing of the fingertips

Chronic Obstructive Pulmonary Disease (COPD)

COPD refers to a group of progressive and chronic lung conditions like emphysema, refractory asthma, and chronic bronchitis. COPD may result in damage to the bronchial tubes, bronchioles, or alveoli (tiny air sacs in the lungs) thus producing an obstruction in the airflow from the lungs. A wet cough may be a symptom of COPD with other accompanying symptoms like (5):

• wheezing
• shortness of breath
• tightness in the chest
• frequent coughing with or without sputum
• fatigue/ tiredness
• weight loss (in later stages)

Congestive Heart Failure (CHF)

Congestive heart failure is a condition where the heart finds it difficult to pump blood through the body. A complication of this condition is pulmonary edema, in the case of which, excess fluid collects in the lungs and enters the alveoli. CHF may result in a wet cough among other symptoms like (6), (7):

• pinkish mucus
• wheezing
• shortness of breath
• fatigue
• swelling in the legs or feet

Now that you are familiar with some of the possible causes, let’s see how to get rid of wet cough by following some home remedies.

Home Remedies For Wet Cough

Here is how to stop coughing using natural remedies and simple practices.

Expectorants And Mucolytics

You can get over-the-counter cough syrups that are formulated with an expectorant or a mucolytic to help thin the mucus so that it is easier for you to cough it up. This wet cough remedy works best if you are having trouble clearing out your airways of mucus and feel that you aren’t coughing up enough phlegm. In particular, look for glyceryl guaiacolate ether, otherwise called guaifenesin, as an ingredient in the over-the-counter cough medications. It is the only legal mucolytic ingredient with efficacy supported by research (8).

Salt Water Gargle

Saltwater gargling benefits your throat and is one of the easiest wet cough remedies you can try. Salt (NaCl) has properties that make it effective against microbes like viruses which are mostly responsible for respiratory tract infections (9). The saltwater may help to reduce the amount of phlegm (mucus) that accumulates at the back of your throat. This in turn can lead to fewer triggers and a reduced frequency of coughs. There are various recipes for a saltwater mix, so pick one that works for you. You can also stir in half a teaspoon of salt in 8 ounces of warm water. Make sure that the water is not too hot when you gargle it.

Oral Zinc Supplements

Try oral zinc supplements or lozenges if you are wondering how to stop a wet cough. Research indicates that zinc, when taken orally, may effectively treat a cold and reduce the severity of its symptoms. However, there need to be further studies to pinpoint its efficacy and understand why zinc seems to work on adults and not work on children. A common side effect of zinc lozenges may be a strange taste in the mouth that many find a little unpleasant (10). However, care should be taken to avoid too much zinc, else it may be toxic.

Honey

Honey is one of the oldest wet cough home remedies. It has anti-microbial and anti-inflammatory properties that help soothe the throat and boost the immune system. A study found that a tablespoon of honey during bedtime reduced the frequency of coughing in children and promoted sleep (11). There is no evidence to suggest that it will not have the same effect on adults. To use honey as a wet cough treatment, eat a tablespoon of honey or stir it into a warm fluid to soothe your throat. Note that honey is not safe for babies under 1 year of age.

Vitamin C

Vitamin C

is one of the much-talked-about wet cough home remedies. A review states that vitamin C on average may lower the duration and the severity of symptoms by 23 percent (12). While more studies are required to prove its efficacy, it may help to take vitamin C when you have a cough. Orange, berries, and lemon or lime are good natural sources. An especially popular and classic remedy incorporating Vitamin C that you can try is a concoction of honey and lemon for cough.

Nasal Irrigation Using A Neti Pot

Studies on the effects of nasal irrigation, especially when done with the help of a neti pot, have shown mostly positive outcomes. That’s because this technique of allowing water to flow freely through the nasal and sinus cavity helps to clear out a lot of mucus from the system. It can help not only clear up headaches and nasal congestion but also reduce the frequency and severity of the wet cough. It is important to use a neti pot in the correct technique to avoid a risk of aspiration (9).

Cool Mist Humidifier

Studies suggest that a humidifier may help relieve cough, but further trials are needed to confirm its benefits (13). Breathing in dry air may further irritate an already stressed out mucous membrane and dry up the mucus, so a cool-mist humidifier is preferred (14).

Drink Plenty Of Warm Fluids

The simplest way to help your body expel as much mucus as possible and thus reduce triggers for cough is to drink plenty of lukewarm fluids. Research suggests that drinking warm fluids can increase the speed and volume of mucus expelled through the nose (15).

Quick Tip

Elevating your head while sleeping can minimize post-nasal drip, thereby reducing the likelihood of coughing at night. You can use an extra pillow to prop yourself up.

Essential Oils

Thyme, clove, and primrose have been studied and found to be effective in the treatment of cold symptoms associated with respiratory tract infections (16). Thyme and primrose have also been studied as a combination therapy for the same and proven to be effective (17). You can inhale the essential oils through a diffuser or inhale them with steam by adding a few drops to a bowl of steaming water.

Some home remedies that may be suitable for adults may not be suitable or effective in babies or toddlers because of the possible difference in underlying causes for the cough.

Wet Cough In A Baby Or Toddler

What causes wet cough in adults is not always what causes it in children, especially those below 15 years of age. The most common reason for a wet cough in infants and toddlers is a viral infection like common colds, croup, acute bronchitis, and influenza. The second most prevalent reason is asthma. Other causes are rare, but may include (18):

• environmental irritants
• whooping cough
• pneumonia

A humidifier may help your child with a cough, especially at night. You can give honey to your child, but you should not give honey to a baby who is younger than 1 year old to avoid the risk of botulism (19).

Some warning signs to look out for when taking care of a child with a wet cough include (18):

• difficulty breathing or shortness of breath
• heaving chest or chest retractions
• malaise
• high fever

Wet cough home remedies may not be enough to treat a cough that is indicative of an underlying health condition or that develops into a complication. Let’s see when it is important to seek out the help of a medical professional.

When To See A Doctor

You need to let your physician know about your condition if you have any of the following symptoms along with a wet cough (20):

• bad-smelling mucus
• yellow, green, or pink-tinged phlegm
• blood with cough
• swollen legs, ankles, or feet
• a prolonged wet cough
• high fever or chills

When you visit your physician, your wet cough condition will be diagnosed properly before you get any prescription.

Wet Cough Diagnosis

To diagnose the underlying reason behind your wet cough, the doctor might ask you questions about your symptoms and conduct a physical examination. If that is not sufficient, or you have accompanying symptoms like fatigue, high fever, or weight loss, you might be asked to go in for additional tests like (21):

• x-rays of the chest
• tests to check lung function
• blood sample test
• sputum analysis
• pulse oximetry
• blood chemistry test and arterial blood gas test

It is common to get mixed up between dry cough and wet cough. It is important to clearly understand the difference so that you can get an accurate diagnosis.

Dry Cough Vs. Wet Cough

The most distinguishing feature between a dry cough and a wet cough is that a dry cough does not bring up mucus. It most often follows a respiratory tract infection, due to irritation or inflammation of your airways. A dry cough may also be caused due to other reasons including environmental irritants, asthma, GERD (gastroesophageal acid reflux), laryngitis, tonsillitis, and allergies (22).

Frequently Asked Questions
