Why diagnosis of Reflux is important
Continuous, untreated gastro-oesophageal reflux disease (GERD/ GORD) or laryngopharangeal reflux disease (LPR) can lead to a very poor quality of life and may also lead to serious problems, such as damage to the oesophagus, oesophageal cancer and cancer of the larynx.
It is dangerous to receive reflux treatment without getting confirmation that symptoms are caused by reflux. Taking medication when it is not needed can cause long-term health problems and may mask a serious problem.
Many people take anti-reflux medication for months or years without understanding the serious risks.
“Using Peptest, the presence of pepsin in my saliva confirmed I was refluxing. By testing around my symptoms, I could see when episodes were happening. With this information, I worked with my doctor to manage my reflux and find the right treatment.”
