 [ Symptoms ] i vomit after having a meal that is beyond the way i used to but they are telling me that i did not ate too much why  when i ate that is greater than i was used to i vomit but people around me keep on saying that you have not eaten that much previously i had a heartburn [ Disease ] maybe you are not eating more than what they think is normal but if your stomach is smaller or has shrunk then you might not be able to eat more than you are used to if you suddenly can not eat as much as you could however you might have another problem that needs a doctor for now maybe you just have a more sensitive stomach maybe it is the irritation from the heartburn
