Hello I have 8 months having throwing up after eating and drinking.I lost 22 pounds without exercising or dieting.Doctors of costa rica do not know what it is.I do not feel nauseous; I only feel very dizzy and weak at times.and changed my eating habits to only eat vegetables Steamed and Grilled Chicken Fish and fruits.Many times I get lucky and only vomit 1 time per day.I make 7 small meals a day.Because I'm afraid of losing so much weight.I'm 22 years old.I hope you can help me please thanks.
