APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -A ring of muscle fibers in the lower esophagus prevents swallowed food from moving back up. These muscle fibers are called the lower esophageal sphincter (LES). When this ring of muscle does not close all the way, stomach contents can leak back into the esophagus. This is called reflux or gastroesophageal reflux.

Detailed explanation-2: -At the junction between the stomach and esophagus is the lower esophageal sphincter. This muscular sphincter acts as a valve that normally keeps food and stomach acid in the stomach, and prevents the stomach’s contents from regurgitating back into the esophagus.

Detailed explanation-3: -Wait at least three hours after eating before lying down or going to bed. Eat food slowly and chew thoroughly. Put down your fork after every bite and pick it up again once you have chewed and swallowed that bite. Avoid foods and drinks that trigger reflux.
