Abstract

Objective: The thyroid is an endocrine organ located in the anteroinferior neck beneath the cricoid cartilage. It produces various hormones, including thyroxine (T4), triiodothyronine (T3), and thyroid-stimulating hormone (TSH), and it plays a key role in regulating overall bodily functions. When secretion is excessive or insufficient, hyperthyroidism or hypothyroidism can be diagnosed, and dysfunction may occur throughout the body. Diagnosis is established by measuring serum thyroid hormone levels, after which an appropriate treatment is applied. Case Report: This case involves a Korean woman in her 50s who reported persistent discomfort across multiple systems—including gastrointestinal, respiratory, dermatologic, and neurologic—and was found on routine health screening to have hypothyroidism, with concurrent hyperlipidemia and anemia. Accordingly, she was prescribed Ortho-Cellular Nutrition Therapy (OCNT) using iodine, selenium, iron, omega-3 and omega-6 fatty acids, red yeast rice extract, anthocyanins, silymarin, and minerals. After OCNT, elevated TSH and cholesterol levels returned to the normal range, and her reported symptoms improved. Conclusion: Because this report concerns a single patient, the generalizability of applying the same OCNT to all individuals with hypothyroidism is limited. Nevertheless, the case suggests that an appropriately tailored OCNT regimen can improve thyroid function in hypothyroidism and enhance the quality of daily life.
