The gallbladder is a muscular storage bag for bile, roughly the size of a small pear, which is attached to the liver, which is on the right side of your tummy, just behind your lower ribs.
A hernia occurs when the layers of muscle of the tummy wall split apart, leaving a gap through which the contents of the abdominal cavity protrude. This is what the lump or bulge is, at the site of your hernia.
Many people suffer from “heartburn”, which is technically referred to as gastro-oesophageal reflux disease (GORD).
