My daughter is 17 years old and has involuntary regurgitation. This began about 3 weeks ago, it would happen occasionally after eating or drinking. As of a week ago it is happening after every meal and today and yesterday she is spitting up nearly one half of every thing she is trying to eat. There is no nausea, only the feeling of needing to burp and when she does, up it comes, no retching (only when the gag reflex is triggered by passing food). She does not have difficulty swallowing or the feeling of food being caught. She says there is a slight bitter taste to the regurgitated food. This is not voluntary. It has begun to interrupt her schooling, and activities because of the hour after eating is spent with a bowl or in the bathroom. She has a history of mild asthma. She also has a family history of esophageal cancer (my mother died about six weeks ago). My daughter is in very good shape, very active in sports and dance. We do have a doctors appointment tomorrow. I just can't sleep for worrying about it and thought maybe there would be some insight here. Thankyou
