Laryngopharyngeal reflux (LPR), also known as “silent reflux,” is a condition that often goes undiagnosed due to its lack of traditional symptoms. However, for those who suffer from it, LPR can cause hoarseness, coughing, difficulty swallowing, and a burning sensation in the throat. It is estimated that 10 percent of people who see a throat specialist have LPR.
LPR occurs when acid and digestive enzymes back up into the larynx and pharynx through the esophagus. Unlike gastroesophageal reflux disease (GERD), which affects the lower esophagus, LPR affects the cavity between the nose and mouth. Although the symptoms of LPR can overlap with GERD, sufferers of LPR often do not experience heartburn or chest pain.
If left untreated, LPR can lead to frequent throat and sinus infections, chronic voice and throat irritation, and vocal cord lesions. Studies have also found a connection between LPR and asthma, pneumonia, and bronchiectasis, which cause the airways in the lungs to become widened and loose.
Diagnosing LPR can be challenging as its symptoms can mimic other diseases. Currently, doctors diagnose LPR based on symptoms and may use laryngoscopies to rule out other conditions. Oral salivary pepsin testing and pH monitoring can also help diagnose LPR. However, reliable diagnostic tests for LPR are still being developed.
Treatment for LPR includes acid-blockers, a low-acid diet, and lifestyle changes such as quitting smoking, limiting alcohol intake, losing weight, and avoiding eating before bedtime. Other recommendations include raising the head of one’s bed or using an inclined pillow. Certain medications, such as Gaviscon or alginates, and muscle relaxants like Baclofen, may also be prescribed.
Individuals who have been diagnosed with LPR have found relief through various treatment methods. One patient, Alicia Ault, followed a strict low-acid diet, took medication, and used nasal rinses to alleviate her symptoms. Another patient, Megha Ramani, made lifestyle changes, practiced yoga and breathing exercises, and received speech therapy. Ruth E. Thaler-Carter, a freelance writer, cut down on certain foods, lost weight, and used a special pillow.
Although LPR can be challenging, there are treatment options available to help alleviate the symptoms and improve quality of life. It is essential for individuals experiencing symptoms of LPR to seek medical attention for an accurate diagnosis and appropriate treatment.
