Heartburn (Overview, Symptoms, Diagnoses, Causes, and 20 Home Remedies)
Lower Esophageal Sphincter(LES) Dysfunction
Many factors like diseases, foods, smoking, alcohol intake can cause damage to the lower esophageal sphincter(LES). The damage to the lower esophageal sphincter(LES) causes weakness of the muscles impairing its function. The stomach acids and foods reflux back towards the esophagus as the sphincter muscles are too weak to contract and relax to avoid the backflow. This backflow of stomach acids causes the condition of heartburn.
