GERD or Gastroesophageal reflux disease is a medical condition that occurs when the acid in the stomach flows back into the esophagus. The esophagus is the tube that connects the mouth to the stomach in the body.
The Gall bladder is an organ which lies just below the liver. It is a side pouch lying to the right of the main channel which carries bile from the liver to the intestine.
Gallstones are hard deposits of solid material, that appear like stones or lumps in the gallbladder – a small, pear-shaped organ located on the right side of the body, directly below the liver.
