Acid Reflux Causes
Acid Reflux occurs because of a weak lower esophageal sphincter (LES), which acts as a valve to control the food passing from esophageal to stomach. In normal digestion, the LES muscles relax to open so foods could pass down to the stomach, where they will be broken down by the digestive enzyme. When the LES muscles tighten to close, it prevents gastric contents from flowing back into the esophagus. However, people living with GERD often have LES dysfunction, which causes the reflux of stomach acid or juice acid. These fluids would erode the esophagus, leading to esophagus ulcers or esophageal erosions.
Certain foods and drinks include spicy foods, alcohol, chocolate, citrus fruits, coffee, and carbonated beverages could be acid reflux triggers. Some medications such as pain relievers, calcium channel brokers, oral osteoporosis drugs, and sedatives often accompany acid reflux as one of their side effects. In addition, pregnant women, obese people, and those living with hiatal hernia or scleroderma are more likely to have acid reflux. [1]
