I had a endoscopy done last week and results were i had gerd and red streak in my esophagus. how long does it take to damage your esophagus. serious?

Esophagitis: Inflammation and acid injury from gerd can take months before significant symptoms are noticed. It needs to be treated as there is a small risk for cancer if it is not.

GERD: Acid reflux damage to the esophagus can occur quickly. However, if treated quickly with some strong acid suppressant therapy, long-term damage to the esophagus can be easily avoided.
