Detection & Treatment
How Do I Know if I Have LPR?
Early/ initial diagnosis of LPR is made if you have the typical symptoms/ signs of LPR.
The ENT doctor may examine your throat with a scope to look for signs of reflux irritation and rule out other dangerous causes of your symptoms.
Your throat and voice box may look red and swollen with excessive phlegm due to the acidic irritation.
Flexible nasoendoscopy at the ENT clinic
In selected cases, a special test known as the '24 Hour PH Probe Study' may be performed by the gastroenterologist to confirm and determine the level of stomach acidic reflux to the throat or voice box area.
How is LPR Treated?
Most cases of LPR do not require medical treatment and can be managed with a change in lifestyle and eating habits.
In selected cases, your doctor may prescribe medications such as proton pump inhibitors, antacids to help lower your gastric acid.
