I m a 18 year old boy, is there a way that gastritis never come again and i can eat any food like others do.

First, get a history: By going to a good doctor he/she should sit down with you get a detailed history of what foods cause you such gastric problems. You also have to consider hyper Zollinger-Ellison syndrome. You should be able to have this worked out and resolved. Try to see a good GI person and if you have had any tests done on you, bring them with you. Read up before your appt. on www.mayoclinic.com or www.johnsho
