**5.1 What are reflux-based diseases?**

This chapter has so far focussed mostly on the swallowing process of conveying food and drink to the stomach successfully, Hiatus hernia has been mentioned only in passing. Here we explain more about this condition. IQoro treats all dysfunctions in the process of swallowing food and drinks safely and successfully, and in retaining it in the stomach without reflux [14, 32]. A distinction between these two areas although often regarded as separate from a healthcare perspective is artificial. The same neuro-physiological processes are common to both dysfunctional swallowing and reflux.
