Answer 1

Gastroesophageal Reflux Disease (GERD) is the condition when a small valve in the lower esophagus leaks, allowing stomach acid to back up from the stomach into the esophagus. It can cause a burning sensation known as heartburn.

Step-by-step explanation:

Condition: Gastroesophageal Reflux Disease (GERD)

Gastroesophageal Reflux Disease (GERD) is the condition when a small valve in the lower esophagus, called the gastro-esophageal sphincter, leaks and allows stomach acid to back up from the stomach into the esophagus. This can cause a burning sensation known as heartburn. If the sphincter fails to remain completely closed chronically, it can lead to GERD, which can cause damage to the esophagus.
