I'm not a doctor, but I can provide some general information. If acid from the stomach (like gastric acid) comes into contact with the esophagus, it can cause irritation or inflammation, a condition known as esophagitis. The severity and symptoms can vary based on several factors, including the concentration of the acid, the duration of contact, and individual susceptibility.
In cases of accidental exposure to acidic substances, the effects can be almost immediate or may develop over several hours to days. Symptoms might include pain or burning in the chest (heartburn), difficulty swallowing, or even more severe symptoms if there is significant damage.
If you or someone else is experiencing symptoms of acid exposure to the esophagus or significant discomfort, it is crucial to seek medical attention promptly. Immediate assessment by a healthcare professional is important to prevent complications.
