*7.1.2 Hiatus hernia and reflux-based conditions*

Reflux occurs when the neck of the stomach and the Lower Esophageal Sphincter (LES) intrude through the diaphragm into the chest cavity. In this position, the LES can open upwards and allow stomach contents to reflux, in its correct position it can only allow one-way traffic downwards. This intrusion or hernia is made possible when the musculature of the diaphragm around the hiatal canal is weakened (**Figure 15**).

IQoro is an effective treatment for reflux-based diseases and their various symptoms: heartburn, pain behind the sternum, persistent unproductive cough, blockage in the throat, and more. Training with IQoro provokes stimuli from the brainstem to flex and strengthen all the muscles in the swallowing chain including those allowing a Hiatal hernia.

The evidence behind the efficacy of IQoro as a treatment for Hiatus hernia includes the following three peer-reviewed and internationally published scientific research papers which are briefly summarized here.
