Abstract

Objective: The coronavirus disease 2019 (COVID-19), first reported in Wuhan, China, is caused by the COVID-19 virus, which triggers acute respiratory symptoms. This virus spreads rapidly through droplets and contact, leading to a global pandemic. The disease presents a variety of symptoms, such as fever, chills, cough, and chest pain, and it can cause sequelae in multiple organs, potentially leading to chronic conditions. Therefore, research into management methods for this disease is urgently needed. Case Reports: The patient in this case is a woman in her 80s, after recovering from COVID-19, developed respiratory sequelae such as cough, phlegm, chest pain, and shortness of breath. Despite taking related medications, her symptoms did not improve, and the quality of her sleep was affected, leading to a decline in her overall quality of life. Therefore, Ortho-Cellular Nutrition Therapy (OCNT), which included anthocyanins, fucoidan, zinc, selenium, and polysaccharides, was prescribed along with lifestyle modifications. As a result, approximately three months later, the patient reported improvement in the symptoms that had caused discomfort, and her quality of life increased as she was able to sleep well. Conclusion: This case report confirms a significant improvement in the sequelae that occurred after the recovery from COVID-19, demonstrating that OCNT may help alleviate the patient's symptoms. However, this case has limitations as it was conducted on a single patient, and the improvement was only observed in respiratory sequelae. Therefore, future large-scale and multifaceted studies are needed to confirm and validate methods for alleviating these sequelae.
