Acid reflux, which is also termed as gastroesophageal reflux, is one of the most frequent problems among infants. Babies with acid reflux often suffer from a range of conditions, from a mild degree to a severe one, such as recurrent spitting up, abdominal pain, and night waking.This discussion would be more comprehensive with the understanding of the physiological or the mechanical aspect of the condition. The body has a band of muscle in a circular structure that is called the lower esophageal sphincter. This muscle detaches the esophagus from the stomach. When food comes into the stomach, it closes so as to prevent the stomach acids and contents from backing up into the esophagus or regurgitating. But in the case of some babies, the lower esophageal sphincter has grown immature. As such, the partially digested food and digestive acids are allowed to be refluxed. This condition causes irritation in the esophagus lining which results to inflammation that is also commonly called as heartburn.
