When you eat or drink something, the food or liquid reaches your stomach by passing from your throat, behind your voice box, and then through a muscular tube called the esophagus to arrive in your stomach.
Once the food reaches your stomach, your stomach puts out acid and pepsin (a digestive enzyme) to digest the food.
Your esophagus has two sphincters (bands of muscle fibers that close off the tube) to help keep the digested food, acid, and pepsin where they belong.
The first sphincter is at the top of the esophagus at its junction with the upper throat just behind the larynx.
The second sphincter is at the bottom of the esophagus at its junction with the stomach. Normally this remains closed until the bolus of food and/or liquid reaches it. However, in many individuals including children, the muscle tone is poor. The sphincter remains open, allowing stomach contents to "reflux" up the esophagus and into the throat.
The refluxed stomach contents may even be aspirated into the trachea, bronchi, and lungs, causing further difficulties.
There may also be a hiatal hernia associated with acid reflux. This is a condition in which part of the stomach slides up above the diaphragm into the chest. Not only do symptoms of reflux occur, but there may be pain around the lower part of the sternum.

Acid Reflux is when the acid in your stomach seeps up into your eshopgus and cases burning pain in your chest area.
This is usually caused by a history of poor diet with lots of grease and fried foods.
I have it and on medication for life.
