I 17 years old have been experiencing burning in my stomach area. no antacids are working. what it could be?

Consult a Doctor: We do not know what you have taken so far, what doses and how often. Burning in stomach can be due to gastritis;peptic ulcer disease.I will suggest if there is no relief with antacids you should consult a gastroenterologist or your doctor gastritis gets better with acid suppression with drugs like ranitidine, Omeprazole and bland diet. Ulcer caused by a bacteria h pylori;treated with antibiotics.
