Why Can Acid Reflux Cause Hoarseness?

Hoarseness, or dysphonia, describes changes in voice quality, making it sound rough, raspy, strained, or breathy. It can also affect the loudness or pitch of one’s voice. Acid reflux is a prevalent digestive condition where stomach contents move upward from the stomach. This article explores the link between acid reflux and hoarseness, including its causes and management.

How Reflux Affects the Voice Box

Laryngopharyngeal Reflux (LPR) is a specific type of acid reflux where stomach contents travel beyond the esophagus into the larynx (voice box) and pharynx (throat). Unlike more common forms of reflux, LPR often occurs without classic heartburn symptoms, earning it the nickname “silent reflux”. In LPR, the sensitive tissues of the larynx and pharynx are exposed to stomach acid and digestive enzymes like pepsin. These tissues are not designed to withstand such exposure, leading to irritation and inflammation.

This irritation results in swelling of the vocal cords, housed within the larynx. When vocal cords swell, their ability to vibrate normally is impaired, directly causing hoarseness. Even small amounts of refluxate can cause significant damage due to the delicate nature of these upper airway tissues.

Recognizing the Symptoms

While hoarseness is a primary indicator of LPR, other associated symptoms can also manifest. Individuals might experience a chronic cough or frequent throat clearing. A sensation of a lump in the throat, known as globus sensation, is also commonly reported. Some people may notice difficulty swallowing or a persistent sore throat.

Additional symptoms can include excessive mucus, a bitter or sour taste, and postnasal drip. LPR symptoms are often subtle, making diagnosis challenging as they can be mistaken for allergies or a prolonged cold.

Managing and Treating Reflux-Related Hoarseness

Managing hoarseness caused by reflux involves various approaches, beginning with lifestyle and dietary adjustments. Avoiding trigger foods such as spicy foods, caffeine, alcohol, fatty foods, and acidic items like citrus fruits and tomatoes can help reduce reflux episodes. Eating smaller, more frequent meals instead of three large ones can also lessen pressure on the digestive system. It is beneficial to avoid eating within two to three hours before bedtime to allow for proper digestion before lying down.

Elevating the head of the bed by four to six inches can help prevent stomach contents from flowing upward during sleep. Maintaining a healthy weight and quitting smoking are also recommended, as both can exacerbate reflux symptoms.

Medical interventions can also play a role in treating reflux-related hoarseness. Over-the-counter antacids provide quick relief by neutralizing stomach acid. Histamine-2 receptor blockers (H2 blockers) like famotidine reduce stomach acid production. Proton pump inhibitors (PPIs) such as omeprazole significantly decrease acid secretion by blocking stomach pumps. These medications help heal irritated tissues by reducing acid exposure.

When to Seek Medical Advice

Consulting a medical professional is advisable if hoarseness persists for more than a few weeks. Seek prompt attention if hoarseness is accompanied by severe symptoms such as difficulty breathing or swallowing. Unexplained weight loss with hoarseness also warrants immediate medical evaluation.

If self-care measures and lifestyle adjustments do not improve symptoms, a doctor can provide further assessment. A healthcare provider, often an otolaryngologist (ear, nose, and throat doctor), can examine the vocal cords and throat for signs of irritation or damage. They can confirm an LPR diagnosis and rule out other potential causes of hoarseness, some of which may be more serious.
