**Study type**

Peer reviewed, prospective, clinical study, cohort pre and post-study [32]. It has been thought that treatment of Hiatus hernia in overweight patients can be unproductive and that weight loss should be a prior step to interventions.

In this study 86 adult patients with verified hiatal hernias and long-standing Intermittent Esophageal Disease (IED) and other Gastro-Esophageal Reflux Disease (GERD) symptoms were grouped according to their Body Mass Index (BMI), before entry into the study (**Table 5**): Group A: normal weight, Group B: moderately obese, Group C: severely obese.
