Hello, Thanks for posting in HCM. Mild esophagitis can be due to multiple causes out of which common is gastroesophageal reflux disease which causes the irritation and inflammation of esophagus causing esophagitis. The treatment for this is lifestyle modification and medications. In lifestyle modification, most important is to get your weight in normal range if you are overweight. Time your lunch and dinner at specific times and follow the timing, irregular dietary habits also can cause this. Have your dinner well before atleast 2hrs before you go to bed. Do not lie down immediately after having food. Avoid spicy, fat rich diet frequently. Start tab omeprazole 20mg 1/2 hr before breakfast and if required before dinner also depending on the effectiveness for your body. You can also take syrup like gelusil when you feel gastric symptoms to relieve from symptom. I hope with all this advice you will feel better and recover quickly. Take care
