Larynx Reflux Disease

Laryngopharyngeal reflux disease describes the condition that results when the acid contents of the stomach flow back up the throat. In this manner, it is similar to gastroesophageal reflux disease, but it often produces different symptoms.

Stomach Acid

• The stomach produces acid to break down food, which facilitates absorption by the intestines. These powerful acids cause damage to other parts of the body if exposed to them, according to Eastern Virginia Medical School.

Causes

• Esophageal sphincters--bands of muscle that keep stomach acids from moving back up--can weaken. One such sphincter lies between the top of the esophagus and bottom part of the neck. It flows over the larynx (voicebox) and up the rest of the throat.

Symptoms

• The stomach acid irritates and inflames the larynx resulting in hoarseness, a feeling of tickling and burning, chronic cough, throat pain, mucus build up, sore throat and trouble swallowing, according to the University of Texas Health Science Center.

Diagnosis

• Doctors diagnose larynx reflux disease through a medical history; physical exam looking at the larynx, throat and vocal cords; and possibly tests that detect the presence of acid reflux in the area.

Treatment

• Lifestyle treatments include avoiding caffeine--particularly acidic sodas, citrus fruits and juices, chocolate, mints, alcohol and foods that promote excess acid production such as spicy foods, fried foods and high-fat foods. Avoiding cigarettes and maintaining a normal weight will also ease symptoms. Medications that reduce stomach acids are also helpful. Severe cases unmitigated by self-care and medication might require surgery, according to Eastern Virginia Medical School.
