Laryngopharyngeal Reflux (LPR)

What Is Laryngopharyngeal Reflux (LPR)?

Laryngopharyngeal reflux (LPR), also known as silent reflux, occurs when a muscle at the end of the esophagus does not close properly. This allows stomach contents to leak back — or reflux — into the esophagus and cause irritation.

Laryngopharyngeal Reflux Symptoms

• Discomfort (heartburn)
• Trouble swallowing

Diagnosing Laryngopharyngeal Reflux

LPR is a diagnosis that people commonly receive if the underlying cause of their symptoms can’t be determined. Swallowing specialists at the Penn Center for Voice, Speech and Swallowing use a well-defined approach to evaluate you and determine if your symptoms are truly the result of LPR. This process begins with a review of your symptoms and medical history.

A series of diagnostic tests may be used to view the inside of your esophagus, stomach, and the first part of your small intestine or to obtain samples of tissue. Diagnostic tests include:

• Barium swallow – an imaging study in which barium, a contrast agent, is used to make internal structures more visible on X-rays
• Endoscopy – an examination of the lining of the upper digestive tract through an endoscope
• pH monitoring – a study that uses a small, wireless capsule, temporarily placed within the esophagus or nasopharynx with an endoscope, to assess whether acid is coming back into the esophagus from the stomach

LPR Treatment Options

In most cases, LPR can be effectively managed with lifestyle changes. Your doctor may recommend any one of the following approaches:

• Weight loss
• Changes to diet
• Reducing the consumption of alcohol and coffee
• Stopping smoking
• Sleeping with the head of the bed elevated
• Avoiding strenuous exercises

If your symptoms don’t improve, you may be cared for in collaboration with gastroenterologists at the Penn Medicine Center for Esophageal and Swallowing Disorders.
