correlation between diet and achalasia is unknown, but there are several procedures that can alleviate the spasms and there is a surgical option called Laparoscopic surgery that has been known to eliminate both spasms and reflux symptoms of achalasia. Read the forums on the following website to decide what treatment is best for you. i also recommend seeing a GI who specializes in achalasia cases, since most doctors, including the GI i talked to, have no idea what achalasia is and can easily misdiagnose/treat the illness. the website is: http://achalasia.net/forumv3/index.php
i highly recommend to anyone who has this affliction to talk to a Gastroenterologist about this and do your own research into it.
