Malnutrition causes serious morbidities and mortalities for both individuals and communities burdens healthcare systems. Its prevalence has become higher during the coronavirus disease 2019 (COVID-19) pandemic. COVID-19 may lead to weight loss, loss of muscle mass, malnutrition, sarcopenia, frailty, and obesity not only at the time of disease but also after disease. Nutrition risk should be assessed for all patients, and individualized nutritional care plan including one during post discharge should be generated. The fact that the risk of malnutrition and loss of muscle mass continue even several months after disease should be considered. Being aware of the increased risk of malnutrition and loss of muscle mass and their consequences during COVID-19 and in the following months would be appropriate.
