Background Sarcopenic dysphagia is a swallowing disorder due to sarcopenia involving the whole-body skeletal muscles and swallowing muscles. This scoping review aimed to explore the currently known information on the diagnosis and treatment of sarcopenic dysphagia and to clarify the types of research required to develop the field. Methods We searched the PubMed, MEDLINE, CINAHL, and Cochrane databases from their inception to October 2020, using the search terms “(sarcopenia or sarcopenic or myopenia or dynapenia) and (dysphagia or swallowing or deglutition) and (diagnosis or treatment)”. Articles reporting diagnosis method and treatment of sarcopenic dysphagia were included. Results Twenty-one and eight articles reported on the diagnostic and treatment method, respectively. A diagnostic algorithm for sarcopenic dysphagia was most frequently used ( n  = 10). Other diagnostic methods included consensus diagnostic criteria for sarcopenic dysphagia ( n  = 4), sarcopenia and dysphagia without other causes of dysphagia ( n  = 4), and both sarcopenia and dysphagia ( n  = 3). The medical treatments for patients with sarcopenic dysphagia were described in single-patient case reports ( n  = 8) only. There were six articles reporting on a combination of rehabilitation and nutritional support. These reports showed the importance of interdisciplinary rehabilitation nutrition for improving patients’ nutritional status and sarcopenia. Conclusions A reliable and validated diagnostic algorithm was the most widely used diagnostic method for sarcopenic dysphagia. Only case reports have been published for the medical treatment of patients with sarcopenic dysphagia. Interdisciplinary rehabilitation nutrition may be useful for treating patients with sarcopenic dysphagia.
