ABSTRACT
Esophageal achalasia is a disease characterized by esophageal motor dysfunction, leading to various symptoms, including vomiting and chest pain. There is no curative treatment for this disease, and the consensus on nutritional therapy or rehabilitation is unclear. Herein, we present the case of a 90-year-old woman with symptoms of esophageal achalasia, exacerbated by secondary sarcopenia and sarcopenic dysphagia after coronavirus disease 2019 (COVID-19) pneumonia. The patient presented with chest pain and vomiting while on a soft diet, and esophagography revealed typical esophageal achalasia. Her esophageal achalasia symptoms resolved, with improvements in nutritional status, skeletal muscle mass, and physical capacity, when a combination of nutritional and comprehensive rehabilitation therapies was adopted. This case highlights that oral dysphagia is associated with worsening esophageal achalasia symptoms and that nutritional and rehabilitative interventions are effective in relieving the symptoms of achalasia in patients with esophageal achalasia and sarcopenia.
