Abstract

Objective: Childhood and adolescence are critical periods of growth in physical, physiological, cognitive, and social aspects. During this time, the formation of immune function through the supply of quality nutrition plays a vital role in maintaining health and supporting growth. Furthermore, recent studies have shown that the composition of the intestinal microbiota plays a crucial role in the development and maintenance of immune function, underscoring the importance of maintaining a balanced microbiota. Case Report: The patient in this case study was a Korean teenage female experiencing gastrointestinal symptoms such as enteritis, diarrhea, abdominal pain, and dyspepsia, along with chronic rhinitis and frequent acute upper respiratory infections. Based on patient interviews, an overall decline in immune function and an imbalance of the intestinal microbiota were identified. Ortho-Cellular Nutrition Therapy (OCNT) was applied to promote improvement in overall symptoms, utilizing anthocyanins, fucoidan, zinc, selenium, vitamin D, Clostridium butyricum, and glycyrrhizin. As a result, the frequency of gastrointestinal symptoms significantly decreased, and the incidence of chronic rhinitis and acute upper respiratory infections was substantially reduced, leading to fewer hospital visits. Conclusion: Appropriate OCNT may help improve the patient’s overall immune function and restore balance to the intestinal microbiota. Since this study involves a single patient, the OCNT protocol may have limitations when applied universally. Nonetheless, the results are considered meaningful, as the individualized OCNT significantly contributed to the patient’s health.
