The primary causes of achalasia cannot be prevented and researchers are still trying to find the reasons behind the occurrence of such malfunctioning of LES muscle. However, the treatment procedures can mitigate the symptoms to a large extent.

Diet for Achalasia
The management of the patient detected with achalasia and nutritional problems they are facing is quite similar to that of patients with dysphagia and esophagogastric cancer. Oral feeding is the most relevant solution which needs to be continued as much as possible. For patients with mild to moderate achalasia, normal diet is mildly affected and, the immediate family members should encourage the patients to follow dietary modifications, so the patients don't face malnutrition or weight loss. Food should be completely individualized for the Achalasia patients. Food needs to be finely chopped, or puréed and fluids may be thickened as much as possible to make the meals easily consumable. One can also start have more fluids along with the food for easy movement of the food through the esophagus.

If Achalasia patient can't eat and drink in sufficient quantities, then tube feeding is the best option for providing sufficient quantities of fluids and nutrients. Some long term complications may occur from the tube feeding that include infections in the esophagus and tube obstruction. Patients who are fed through gastric tube, there remain a possibility of pulmonary aspiration and in such situations intrajejunal feeding procedure is recommended for these cases.
