Im experiencing really really bad heartburn, especially when i consume alcohol or eat certain foods. ive never really had much of an appetite so i dont eat much food, and it feels like that makes it even worse.

Need to examine: It is not feasible to provide a meaningful opinion without additional history, physical examination and may be some tests. Thee are multiple causes of heartburn. Gastroesophageal reflux needs to be excluded as it can cause damage to the food pipe It would be prudent to see your doctor, preferably a gastroenterologist. Stay away from alcohol. Wish you good health!
