Causes of Reflux

• Between your esophagus and your stomach you have a “valve”, the lower esophageal sphincter (LES) that normally remains closed to prevent reflux from the stomach content into the esophagus. After you swallow something, the food, drink or saliva reaches the LES. It promotes relaxation of the sphincter allowing the passage into the stomach. The sphincter may be weakened due to several reasons, causing it to be partially open allowing stomach secretion to “reflux” into the esophagus.
• It is important to understand that the reflux can also be alkaline such as bile reflux. It can actually be more dangerous since it is not as symptomatic as the acid reflux.
• Patients may also have a defect or weakness at the area where the esophagus passes into the abdominal cavity, known as hiatal hernia, allowing part of the stomach to transiently or permanently be pushed up into the chest.
• Patients may have a stricture or narrow area in a more distal area in the stomach or duodenum, preventing the normal flow of food. It can lead to increase pressure.
• The end result of the reflux may lead to stomach contents to reflux and potentially “burn” the esophageal lining. Chronic reflux, acid or non-acid may lead to serious complications.
  Proper evaluation is going to allow proper diagnosis and therefore a better alternative treatment for your case.
