Gastro-oesophageal reflux refers to the passage of food or acid in the wrong direction from the stomach into the oesophagus (gullet).

The basis of most Obesity Surgery (also known as Bariatric Surgery) is to restrict the amount of food able to be eaten and for satiety (feeling full) to be reached only after a small amount of food is eaten.

Keyhole Surgery also known as Minimally Invasive Surgery is surgery performed using long thin instruments inserted into the body through small cuts (incisions).
