Acid Reflux

Definition

Acid reflux is a condition that occurs when stomach acid flows back into the tube connecting your mouth and stomach (esophagus), causing irritation and discomfort often described as heartburn.

Scientific / Technical Definition

Acid reflux, also known as gastroesophageal reflux disease (GERD) when chronic, is a condition characterized by the backward flow of stomach acid into the esophagus. This can lead to symptoms such as a burning sensation in the chest (heartburn), regurgitation of food or sour liquid, and difficulty swallowing.

Benefits

• Understanding and managing acid reflux can help prevent esophageal damage.
• Improving dietary habits can reduce symptoms and enhance quality of life.
• Effective management can decrease the likelihood of complications such as esophagitis or Barrett's esophagus.

Examples

• Common triggers include acidic foods like citrus and tomatoes, as well as fatty or spicy foods.
• Lifestyle changes such as elevating the head during sleep may alleviate symptoms.

Additional Information

• Known issues: Long-term untreated acid reflux can lead to more serious health issues such as esophageal strictures or Barrett's esophagus.
