How is Laryngopharyngeal Reflux Treated? Symptoms, Diet, and Medication Options

Laryngopharyngeal Reflux

Complaints such as burning in the throat, hoarseness, or a persistent cough are common in many people in daily life. Although these symptoms are often mistaken for a common cold, the underlying cause can sometimes be different. One of these conditions is laryngopharyngeal reflux. Although it may seem like a digestive system issue, this condition affects the throat, vocal cords, and upper respiratory tract, and can seriously reduce quality of life.

What is Laryngopharyngeal Reflux?

Laryngopharyngeal reflux is a health condition that occurs when stomach contents pass through the esophagus and reach the throat, and even the nasopharynx and vocal cords. In medicine, it is referred to as "laryngopharyngeal reflux" (LPR). This condition differs from classic gastroesophageal reflux because typical reflux symptoms, such as heartburn or chest pain, are often absent. Therefore, it is also called silent reflux. The main difference between throat and stomach reflux is that laryngopharyngeal reflux predominantly affects the upper respiratory tract and throat tissues, whereas stomach reflux is typically felt in the esophagus.

In laryngopharyngeal reflux, stomach acid, bile, and digestive enzymes reach the throat and damage the delicate tissues there. Over time, this leads to issues such as throat burning, hoarseness, chronic cough, and difficulty swallowing. Because reflux affects not only the digestive system but also the respiratory tract and vocal quality, making an accurate diagnosis is extremely important. The distinction between laryngopharyngeal reflux and gastroesophageal reflux can be clearly made here.

What Are the Symptoms of Laryngopharyngeal Reflux?

Laryngopharyngeal reflux symptoms are quite varied and are often confused with other diseases by patients. This complicates the diagnostic process and can cause the disease to become chronic.

Hoarseness: Laryngopharyngeal reflux commonly results in hoarseness. Patients notice that their voice is hoarse especially when they wake up in the morning and improves during the day. This condition is caused by edema and inflammation resulting from the vocal cords coming into contact with acid throughout the night. Laryngopharyngeal reflux hoarseness can sometimes persist for days and cause difficulty speaking. Additionally, laryngopharyngeal reflux can lead to conditions such as nasal congestion.

Sore Throat and Burning Sensation: Sore throat and a burning sensation are frequently encountered complaints due to reflux. Patients experience a persistent soreness and irritation in the throat. This pain increases especially during swallowing. Furthermore, laryngopharyngeal reflux can also result in ear pain. The burning sensation in the throat typically becomes more pronounced after consuming acidic or spicy foods.

Cough: Chronic cough is one of the most annoying symptoms of laryngopharyngeal reflux. This cough is generally dry in character and intensifies particularly at night and when lying down. Patients experience a deterioration in sleep quality due to this cough and disturb those around them. The cough can sometimes be so severe that it can trigger a vomiting reflex.

Sensation of Phlegm: Laryngopharyngeal reflux can cause a sensation of phlegm and a constant need to clear the throat. Patients feel as though there is a sticky substance in their throat and constantly feel the need to clear it. Additionally, laryngopharyngeal reflux can also lead to conditions such as belching. This situation creates discomfort, especially in social environments, and can be embarrassing for the patient.

Difficulty Swallowing: Difficulty swallowing is observed in advanced cases. Patients experience difficulty, especially when swallowing solid foods, and sometimes have the sensation that food is stuck in their throat. This condition can lead to changes in dietary habits and weight loss.

Difficulty Breathing: Laryngopharyngeal reflux can also lead to shortness of breath. Difficulty breathing and a choking sensation can occur particularly at night. Patients have trouble breathing during sleep and wake up feeling as though they are choking. This condition seriously disrupts sleep quality and causes daytime fatigue.

How Does Laryngopharyngeal Reflux Occur?

Laryngopharyngeal reflux occurs when stomach contents, which normally should remain solely inside the stomach, escape upward and reach the vocal cords and throat. The primary cause of this condition is that the muscles located at the lower and upper parts of the esophagus (esophageal sphincters) do not close tightly enough.

In the stages of its occurrence, the stomach first creates an acidic environment to facilitate digestion. Normally, this acid does not cross the stomach wall. However, if the lower esophageal valve (lower esophageal sphincter) is loose, the acid travels upward and classic reflux symptoms occur. If the upper esophageal valve is also weak, the acid travels even further up, affecting the throat, nasopharynx, vocal cords, and sinuses. In this case, stomach acid comes into direct contact with the throat tissues and causes irritation.

There are multiple causes of laryngopharyngeal reflux. Dietary habits are among the most important factors. Acidic foods, spicy meals, chocolate, caffeine, alcohol, and smoking relax the sphincter muscles. Additionally, overeating, lying down immediately after meals, and carbonated beverages also trigger reflux.

Anatomic factors also play an important role. Hiatal hernia, obesity, pregnancy, and changes occurring during the aging process increase the risk of reflux. In a hiatal hernia, a portion of the stomach is located above the diaphragm, impairing lower esophageal sphincter function. Hormonal changes affect the frequency of reflux, especially in women. During pregnancy, increasing progesterone hormone relaxes the sphincter muscles. Furthermore, the growing baby exerts pressure on the stomach, triggering reflux.

Certain medications also facilitate the development of reflux. Antidepressants, blood pressure medications, bronchodilators, and pain relievers can impair sphincter function. Patients should inform their doctors when using these medications, and alternative treatment options should be evaluated if necessary. Stress and psychological factors play an indirect role in the development of reflux. Stress increases stomach acid production and disrupts the coordination of sphincter muscles. Moreover, during stressful periods, people tend to eat more, smoke, and consume alcohol. This in turn triggers reflux.

How Is Laryngopharyngeal Reflux Diagnosed?

Diagnosing laryngopharyngeal reflux can sometimes be difficult because the symptoms of the disease are generally non-specific and can be easily confused with other illnesses. In particular, the differential diagnosis of pharyngitis and laryngopharyngeal reflux must be performed carefully. Therefore, taking a detailed patient history, listening carefully to complaints, and applying accurate diagnostic tests are very important. Diagnosis can be made through the following methods:

Clinical Evaluation: The doctor listens to the patient's complaints and gathers information about the duration, severity, and onset of the symptoms. Symptoms such as hoarseness, tickling in the throat, and difficulty swallowing are evaluated with particular care.

Endoscopic Examination (Laryngoscopy): Laryngopharyngeal reflux can be detected via endoscopy. An Ear, Nose, and Throat (ENT) specialist directly examines the throat and vocal cords using a thin camera. This method checks for redness, edema, irritation, or mucus accumulation.

pH Monitoring: Using a thin tube placed in the esophagus, it is measured whether stomach acid is refluxing upward. This 24-hour test is one of the most reliable methods in diagnosing laryngopharyngeal reflux.

Empirical Treatment (Trial Treatment): In some cases, reflux medications are prescribed directly for diagnosis. If the patient's complaints improve with these medications, the diagnosis of laryngopharyngeal reflux is confirmed.

Because diagnostic accuracy directly affects treatment success, patients should be patient during this process.

How is Laryngopharyngeal Reflux Treated?

Laryngopharyngeal reflux treatment is planned according to the severity of the disease, its impact on the patient's quality of life, and individual factors. The treatment approach includes lifestyle modifications, medical treatment, and surgical interventions when necessary. Lifestyle modifications form the cornerstone of treatment. Laryngopharyngeal reflux can be significantly prevented by regulating dietary habits. In particular, restricting foods that trigger reflux and adjusting meal timings are of great importance. Within the scope of the laryngopharyngeal reflux diet, patients should reduce the consumption of acidic foods, spicy meals, chocolate, caffeine, and alcohol.

Portion control and meal times are also critical factors. Small, frequent meals should be preferred over large portions. Waiting at least 3 hours after meals before lying down reduces the risk of reflux. Furthermore, drinking plenty of water during meals and chewing slowly are also beneficial.

Weight control is important, especially in obese patients. Excess weight increases intra-abdominal pressure and triggers reflux. Reaching an ideal weight through regular exercise and a balanced diet can significantly reduce symptoms. Sleep positioning and bed arrangement are also part of treatment. Elevating the head of the bed by 15-20 cm prevents acid from rising due to the effect of gravity. Sleeping on the left side can reduce reflux due to stomach anatomy.

In medical treatment, proton pump inhibitors (PPIs) are the first-choice medications. These drugs significantly reduce stomach acid production and bring reflux symptoms under control. In cases of persistent laryngopharyngeal reflux and in patients unresponsive to medical treatment, laryngopharyngeal reflux surgery can be considered. Fundoplication surgery helps prevent reflux by creating a wrap around the stomach. However, this surgery should only be performed in highly selected patients and by experienced surgeons. Regular follow-up and monitoring are required during the treatment process. Patients should report changes in their symptoms to their doctors, and medication doses should be adjusted when necessary. In most patients, symptoms are brought under control within 4-8 weeks with appropriate treatment.

Frequently Asked Questions

In gastroesophageal reflux, stomach acid generally rises up to the esophagus and causes typical symptoms such as chest burning. In laryngopharyngeal reflux, however, the acid passes beyond the esophagus and reaches the throat, nasopharynx, and vocal cords. Therefore, laryngopharyngeal reflux is known as "silent reflux" and most of the time occurs without heartburn. Additionally, laryngopharyngeal reflux can also cause symptoms such as headache. Laryngopharyngeal reflux can irritate the vocal cords and lead to hoarseness. Particularly a crackling voice in the mornings, difficulty clearing the voice, or voice fatigue during the day are typical symptoms of laryngopharyngeal reflux. If these conditions recur frequently, it is necessary to consult an Ear, Nose, and Throat (ENT) specialist. If laryngopharyngeal reflux continues untreated for a long time, it can lead to chronic irritation in the throat and vocal cords. However, it is not scientifically clear whether it directly causes cancer. Nevertheless, changes in cellular structures can develop due to long-term reflux. Therefore, regular monitoring and treatment should not be neglected. Patients with suspected laryngopharyngeal reflux should first consult the Ear, Nose, and Throat (ENT) department. If necessary, the ENT specialist may refer you to the gastroenterology department. Because the source of reflux is the stomach, some patients may require both branches to work together. Dietary order is very important in laryngopharyngeal reflux. Acidic, spicy, fatty, and fried foods should be avoided; chocolate, coffee, carbonated beverages, and alcohol should be limited. Food should not be consumed at least 2-3 hours before lying down. Eating a high-fiber, light diet with small portions is recommended. In mild cases, laryngopharyngeal reflux can be brought under control with lifestyle modifications. However, most patients require medication therapy that suppresses stomach acid. It is difficult for it to resolve completely without medication, but significant improvement can be achieved in early stages through diet, stress management, and sleep regulation. Laryngopharyngeal reflux is suspected if there is a persistent tickling in the throat, a non-stopping cough, morning hoarseness, the sensation of something stuck in the throat, and a frequent need to clear the throat. However, for a definitive diagnosis, evaluation by an ENT specialist is essential. Only symptoms can be monitored at home. Cough related to reflux is generally dry, persistent, and more severe at night. Unlike a cold or allergy, it is accompanied by a burning sensation in the throat, morning hoarseness, and chest tightness. If your cough has lasted longer than 2-3 weeks and does not respond to medications, reflux should be considered.
