Following POEM treatment for achalasia, patients are advised to consume liquid and soft foods during their hospital stay (typically 2-3 days). This dietary regimen should be continued for the first two weeks after discharge from the hospital. After this period, a gradual transition to a normal diet can be made. In the long term, it is important to avoid foods that may cause reflux, consume small and frequent meals, and ensure food is thoroughly chewed before swallowing.
