Main Causes Of Heart burn
The digestive system involves a bunch of organs, including the mouth, esophagus, stomach, small intestine, large intestine, and rectum. When food enters the mouth, it gets incorporated with saliva to move further smoothly. The esophagus has a mechanism of peristalsis i-e the small contractions of the esophageal muscles to move the food to the stomach. The lower esophageal sphincter (LES) is a circular muscular valve that allows the inflow and outflow of food from the esophagus to the stomach. This sphincter gets damaged due to a person’s poor digestive system. The muscular valves become weak and do not function properly. This impairment of the digestive organ’s muscles causes the backflow of acids into the esophagus leading to heartburn.
