Inside Constant Throat Clearing

Understanding and Causes of Persistent Throat Clearing

Persistent throat clearing is a common symptom characterized by the frequent urge to clear one’s throat due to the sensation of an obstruction. This condition can be both bothersome and socially inconvenient.

The reasons for persistent throat clearing vary and include:

Allergies: Allergic reactions can lead to postnasal drip, which involves mucus running down the back of the throat, causing irritation.
Acid Reflux: Gastroesophageal reflux disease (GERD) or acid reflux may cause stomach acids to back up into the esophagus and throat, resulting in irritation that prompts throat clearing.
Medications: Some medications can cause a dry mouth or contribute to GERD, indirectly leading to more frequent throat clearing.
Infections: Respiratory infections like colds or sinusitis increase mucus production, triggering this response.
Irritants: Exposure to irritants such as smoke, pollution, or strong odors can provoke persistent coughing and throat clearing.

Identifying the underlying cause(s) is crucial for understanding this condition.

Reflux and Postnasal Drip: Common Throat Clearing Culprits

Many individuals experience frequent throat clearing. This phenomenon can be a nuisance and may also indicate underlying health conditions. Two prevalent causes are reflux and postnasal drip.

Reflux occurs when stomach acid ascends into the throat, a condition known as GERD (Gastroesophageal Reflux Disease). The symptoms associated with this condition include:

A burning sensation in the chest (heartburn)
Sour taste in the mouth
Frequent throat clearing

The cause of throat clearing in this context is the irritation of the throat lining by acid.

Postnasal drip is characterized by the accumulation of excess mucus dripping down from the back of the nose into the throat. The origins of this condition can range from allergies to the common cold or flu. The presence of mucus buildup prompts the sensation of needing to clear the throat.

Both conditions can interfere with daily activities but can be managed with appropriate treatment strategies. Identifying the underlying cause of frequent throat clearing is beneficial for determining the appropriate management approach.

Rare and Neurological Causes of Throat Issues: Zenker’s Diverticulum, Chronic Motor Tic, and Tourette Syndrome

When throat issues persist beyond common causes like infections or allergies, rare conditions such as Zenker’s Diverticulum, Chronic Motor Tic, and Tourette Syndrome may be considered. Each condition has unique symptoms that can significantly affect the throat.

Zenker’s Diverticulum

A rare condition in which a pouch forms at the back of the throat, often due to weakened muscles in older adults.
Symptoms include difficulty swallowing, coughing up food not recently eaten, bad breath, and a sensation of something stuck in the throat.
It is caused by increased pressure during swallowing that forces part of the lining through the muscle wall.

Chronic Motor Tic Disorder

This disorder involves sudden, uncontrollable movements or sounds (tics) affecting various body parts, including the throat.
For throat issues specifically, individuals might experience tics that cause them to repeatedly clear their throats or make grunting noises unintentionally.
For diagnosis, these tics must be present for more than a year without any vocal tic manifestations typical of Tourette Syndrome (TS).

Tourette Syndrome

Tourette Syndrome affects an individual's motor functions and speech, including abrupt involuntary sounds like coughs or shouts which directly involve the throat area.
Vocal tics are common, ranging from simple sounds such as hiccups to complex phrases involuntarily spoken out loud.
Symptoms tend to fluctuate over time but are persistent.

Treatment options for these conditions vary, including watchful waiting in some cases of Zenker's diverticulum, behavioral therapy for chronic motor tic disorder, and comprehensive clinical interventions combining medication with therapy for Tourette syndrome management.

Unique Triggers for Throat Problems: PANDAS and Food Allergies

When considering throat problems, common triggers like colds or strep throat often come to mind. However, unique triggers such as Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal Infections (PANDAS) and food allergies can also be factors.

PANDAS is a rare condition that emerges in children after a strep infection. Unlike typical strep throat cases, PANDAS affects the brain, leading to sudden changes in behavior, mood, and physical movements. Symptoms can include obsessive-compulsive behaviors, tics, anxiety, and attention difficulties. The connection between a throat infection and these symptoms lies in how the body's immune system responds to the infection by mistakenly attacking not just the bacteria but also parts of the brain.

Food allergies can also lead to unexpected throat issues, ranging from mild irritation to serious conditions like anaphylaxis—a rapid onset allergic reaction that can be life-threatening. Foods commonly associated with allergic reactions include nuts, dairy products, eggs, soy, and wheat, among others. Symptoms related to the throat may include swelling (known medically as angioedema), itching, or scratchiness inside the mouth or back of the throat.

Understanding these triggers is vital due to their potential severity and the fact that they require different management approaches compared to more common causes of sore throats. For instance:

Treatment for PANDAS may involve antibiotics for lingering streptococcus bacteria, along with therapies addressing neurological symptoms.
Managing food allergies involves identifying problematic foods through testing, followed by the strict avoidance of identified allergens, alongside carrying emergency medication like epinephrine auto-injectors for accidental exposure.

Awareness about less-known causes behind throat problems helps pave the way for timely diagnosis and appropriate care.

Throat Clearing from Medication Side Effects

Many people experience the need to clear their throat often, which can be both annoying and sometimes concerning. One less known cause of frequent throat clearing is medication side effects.

Medications can affect the body in various ways, including causing dryness in the mouth and throat or producing extra mucus. Both situations may lead individuals to clear their throat more than usual. Some medications that are commonly linked with this side effect include antihistamines, blood pressure drugs, antidepressants, and some muscle relaxants.

Understanding why this happens may assist in managing the issue:

Antihistamines, while relieving allergy symptoms, also reduce saliva production leading to a drier throat.
Certain drugs for high blood pressure can cause swelling or irritation in the vocal cords.
Antidepressants and muscle relaxants can decrease saliva production or increase mucus as a side effect.

Persistent throat clearing after starting new medication could signal the need for a review of the medication regimen. Adjustments in the dose or a switch to another medication might be considered. Additionally, increasing water intake and using humidifiers at home can alleviate some discomfort.

It is important to maintain open communication with healthcare providers regarding any side effects experienced, ensuring the effectiveness of treatment is maintained while managing side effects.
