When I lie down I can hear my stomach when I breathe kind of like when I breathe in then something moves in my wind pipe but instead it appears to be something small moving in my stomach and it also makes these horrible squelching noises.  I also seem to have a lot of built up gas in between meals which when I burp also leads to the horrible squelching noise.  I used to be bulimic, do you think I could have damaged my stomach in some way?
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of HERD (gastroesophageal reflux disease) is more. HERD is due to laxity of gastroesophageal sphincter. Because of this the acid of the stomach tends to come up in the esophagus and cause the symptoms of chest pain, gaseous distention of stomach and noises from stomach. So better to avoid hot and spicy food. Avoid junk food. Avoid stress and tension. Avoid large meals, instead take frequent small meals. Take proton pump inhibitors and prokinetic Chat Doctor.  Quit smoking and alcohol if you have these habits. Don't worry, you will be alright. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
