Throat Clearing Symptoms

Clearing the throat is a functional response to irritating substances. However, excessive throat clearing can be irritating. Several structures from the respiratory and digestive system may be involved in underlying causes of throat clearing, including the esophagus, larynx, and vocal cords. In many cases treatment for an underlying medical condition will be required to relieve excessive throat clearing.

Symptoms that can be associated with throat clearing include:

Throat Clearing Causes Overview

Gastrointestinal problems:

  • Reflux: When contents of the stomach re-enter the esophagus after meals, food particles and stomach acid can end up in the larynx and vocal cords. This results in irritation and damage over time, and frequent throat clearing is common along with sore throat and hoarseness [1, 2].
  • Swallowing disorders: Difficulty swallowing food completely due to structural or neurological abnormalities of the esophagus can cause regurgitation of food particles. The resulting irritation of the throat leads to excessive throat clearing. Bad breath and coughing may also occur.

Respiratory problems:

  • Postnasal drip: Nasal drainage into the back of the throat causes irritation that commonly results in chronic cough and throat clearing [3]. This condition can occur due to environmental allergies or a respiratory infection [4, 5].
  • Larynx and vocal cord conditions: Structural abnormalities of the vocal cords, such as polyps or nodules, can cause throat clearing along with voice changes and noisy breathing. Chronic inflammation of the larynx, which may be due to allergens in the environment and/or postnasal drip, can also cause throat clearing symptoms.
  • Lung conditions: Medical conditions involving the lungs, including chronic bronchitis and asthma, can be associated with throat clearing. Other symptoms such as difficulty breathing and coughing will be present [7].

Other throat clearing causes:

  • Tic disorders: Certain neurological disorders including Tourette syndrome cause involuntary movements and vocalizations called tics. Examples of tics include throat clearing, shrugging, and sniffing [8].
  • Medications: Inhaled steroids and certain blood pressure medications can cause throat clearing as a side effect [9, 10].
  • Habit: Some people develop habitual throat clearing due to the perception of an irritating sensation, even without any underlying medical condition causing throat irritation [7].

A.I. Health Assistant Causes for Throat Clearing

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced throat clearing. This list does not constitute medical advice.

  1. 1.Acid Reflux Disease (Gerd)

    Acid reflux disease, also known as GERD, occurs when the acidic contents of the stomach come back up into the esophagus. The most common symptoms are heartburn and regurgitation.

    With proper treatment, symptoms may be relieved within days & at most several weeks.

    Top Symptoms:
    nausea, sore throat, pain below the ribs, cough with dry or watery sputum, deep chest pain, behind the breast bone
    Primary care doctor
  2. 2.Bronchiectasis

    Bronchiectasis is destruction and widening of the large airways. Mucus builds up in these airways and can get infected, causing a pneumonia.


    Top Symptoms:
    cough, shortness of breath, wheezing, runny nose, mucous dripping in the back of the throat
    Primary care doctor
  3. 3.New - Onset Seasonal Allergies

    Allergic rhinitis, is an overreaction by the immune system to allergens in the air. While pollen often causes allergies, other culprits include dust, animal dander, and mold.

    Allergies are often seasonal.

    Top Symptoms:
    sore throat, congestion, cough with dry or watery sputum, mucous dripping in the back of the throat, fatigue
    Symptoms that never occur with new-onset seasonal allergies:
    fever, yellow-green runny nose, chills, muscle aches
  4. 4.Adult - Onset Asthma

    Asthma in adults is an under-diagnosed reason for a chronic cough. In general, asthma is caused by hyperactive inflammation of the lung's airways. This results in episodic dyspnea, coughing and wheezing which is triggered by for example exercise, cold air, pollen or dust.


    Top Symptoms:
    fatigue, wheezing, dry cough, shortness of breath at rest, shortness of breath on exertion

  5. 5.Post - Infectious Cough

    Post-infectious upper airway cough is a condition that can develop as a direct result of a previous infection of the airways. In adults, this is the most common cause of chronic (persistent) cough.

    2 weeks with treatment.

    Top Symptoms:
    cough, congestion, clear runny nose, mucous dripping in the back of the throat, hoarse voice
    Symptoms that always occur with post-infectious cough:
    Symptoms that never occur with post-infectious cough:
    Phone call or in-person visit
  6. 6.Viral Throat Infection

    Viral pharyngitis is an inflammation of the pharynx, the part of the throat between the nasal cavity and mouth, which causes throat pain.

    Symptoms generally resolve within 3-4 days

    Top Symptoms:
    sore throat, cough, congestion, fever, hoarse voice
    Symptoms that always occur with viral throat infection:
    sore throat
    Symptoms that never occur with viral throat infection:
    being severely ill
  7. 7.Foreign Body Aspiration

    Foreign body aspiration can be a life-threatening emergency. An aspirated solid or semisolid object may lodge in the larynx or trachea. If the object is large enough to cause nearly complete obstruction of the airway, asphyxia may rapidly cause death.

    Resolves as soon as treatment is provided

    Ultra rare
    Top Symptoms:
    cough, fever, shortness of breath, cough with dry or watery sputum, wheezing
    Symptoms that always occur with foreign body aspiration:
    swallowing of something potentially harmful
    Emergency medical service
  8. 8.Bronchitis

    Bronchitis is an inflammation of the bronchial tubes, the airways that carry air to your lungs. It causes a cough that often brings up mucus, as well as shortness of breath, wheezing, and chest tightness. It is typically caused by a virus.

    Symptoms resolve within 1-2 weeks.

    Top Symptoms:
    cough, productive cough, sore throat, wheezing, coughing up green or yellow phlegm
    Symptoms that always occur with bronchitis:
    Symptoms that never occur with bronchitis:
    nausea or vomiting

Throat Clearing Treatments and Relief

The majority of causes of throat clearing do not require urgent evaluation. However, excessive throat clearing can be associated with respiratory conditions that have dangerous exacerbations. Seek emergency treatment if you are having severe difficulty breathing.

Make an appointment with your medical provider if:

  • You have a sensation of something stuck in your throat or chest [7].
  • You have a chronic cough or difficulty breathing when you exert yourself.
  • You have previously been diagnosed with a chronic respiratory or gastrointestinal condition and now are having worsening symptoms [1, 2, 3].
  • Your throat clearing is causing personal discomfort and/or problems in social settings.
  • Your throat clearing started after you began a new medication [9, 10].
  • You have involuntary movements and vocalizations in addition to throat clearing [8].

Your medical provider may prescribe one or more of the following treatments, depending on the cause of your throat clearing symptoms:

  • Inhalers and possibly also oral steroids to treat asthma or chronic bronchitis [9, 10].
  • Medication to prevent tics such as throat clearing if they are impairing daily functioning [11].
  • Stopping a medication that may be causing throat clearing [9, 10].
  • Medication to decrease stomach acid in order to reduce the negative effects of reflux [1, 2].
  • Referral for surgical management of gastrointestinal disorders if more conservative treatments are not effective [1, 12, 13, 14].
  • Referral to a "vocal hygiene" program to help eliminate habitual throat clearing [14].

Some home treatments may help with throat clearing.

  • To alleviate reflux symptoms, avoid eating meals late at night and cut back on spicy foods, caffeine, and alcohol.
  • Cutting back on smoking or, ideally, quitting altogether will help with respiratory causes of throat clearing.
  • Several over the counter medications including antihistamines, decongestants, and nasal steroid sprays can help with postnasal drip [1, 5, 6].
  • Try taking a sip of water when you experience the urge to clear your throat.
  • If you experience difficulty swallowing, try eating slowly, taking smaller bites, and chewing food thoroughly [1, 6, 14].

FAQs About Throat Clearing

Here are some frequently asked questions about throat clearing.

Can throat clearing be caused by allergies?

Yes, allergies can cause the need for throat clearing. Allergens inhaled from the environment, such as dust, can cause irritation of the larynx that leads to throat clearing. In addition, environmental allergies can cause post-nasal drainage associated with chronic nasal discharge and congestion [5, 7, 9]. The presence of drainage in the throat triggers coughing and throat clearing.

Could a new medication be causing my throat clearing?

Certain medications can cause throat clearing as a side effect. A class of blood pressure and heart medications called ACE (angiotension converting enzyme) inhibitors can cause coughing and throat clearing due to a buildup of substances that irritate the airways. Inhaled steroids can also cause throat clearing; in this case, the medication causes direct irritation to the larynx.

How can I get rid of the urge to clear my throat?

If throat clearing is a side effect of a medication, stopping the medication will lead to eventual improvement. Treatment for allergies or an underlying medical condition contributing to throat clearing will also help. Sometimes throat clearing becomes a habit, in which case taking a sip of water as a replacement can help get rid of the urge. For many causes of throat clearing, avoiding environmental irritants such as cigarette smoke will lead to improvement.

Can throat clearing be caused by GERD?

Yes, excessive throat clearing can be a symptom of GERD [1]. Gastroesophageal reflux disease is a condition where acid and food particles from the stomach re-enter the esophagus [6]. Although GERD is usually associated with heartburn, for some people, other symptoms due to irritation of the larynx are more prominent. Laryngeal symptoms include throat clearing, hoarseness, and coughing.

Can respiratory problems contribute to throat clearing?

Yes, problems with various parts of the respiratory tract can cause a need for excessive throat clearing. Asthma and chronic bronchitis can both cause throat clearing along with the more common symptoms of cough and difficulty breathing [9, 10]. In addition, the vocal cords and larynx can be irritated by voice overuse or reflux from the stomach, leading to throat clearing as well as hoarseness. The uppermost part of the respiratory tract can be affected by post-nasal drip, usually due to allergies or a respiratory infection [5, 14]. In this case, irritation of the throat triggers throat clearing.
