The esophagus can be affected by acid reflux or esophagitis, which is when stomach acid irritates the lining of the esophagus. The timeframe for this damage can vary significantly based on several factors, including the acidity of the stomach contents, the frequency and severity of reflux episodes, individual susceptibility, and how long the acid stays in contact with the esophagus.
In general, a single episode of acid reflux might not cause immediate visible damage, but repeated exposure over time can lead to more serious conditions, such as inflammation, ulcers, or Barrett's esophagus. For some individuals, even a few minutes of acid contact can be uncomfortable and may lead to symptoms.
If you're experiencing frequent acid reflux or esophageal discomfort, it's important to consult a healthcare provider for an accurate diagnosis and appropriate management.
