Nutritional Management of Hashimoto's Thyroiditis: A Case Report.

INTRODUCTION

Hashimoto's thyroiditis (HT) is prevalent in about 1 in 1000 people. A 39-year-old female diagnosed with HT was having unsuccessful symptom resolution with conventional thyroxine (T4) replacement therapy. In 60 days, there was a remarkable reduction of thyroid antibodies (Ab), improvement of thyroid hormones, and cardiometabolic biomarkers following a Paleolithic diet (PD).

CASE DESCRIPTION: A patient unable to lose weight or alleviate gastrointestinal and neurological symptoms after maintaining clinical thyroid stimulating hormone (TSH) levels through conventional T4 medication therapy saw significant reductions in thyroglobulin (47.5%) and thyroid peroxidase (28.9%) Abs, and significant improvement in TSH (36.4%) total T4 (21.5%) and total T3 (33.3%) after 60-day treatment intervention with the PD. Improvements were also seen in HDL (31.6%), LDL (8.9%), total cholesterol (14.9%), and weight (11.5%). The client adhered to a weekly step process of avoidance of foods that have known hypersensitivities and consumed high-quality fats, fermented foods, filtered water, and green tea, and took a daily nutritional supplementation of vitamin D used in conjunction with a homemade turmeric spice blend. Upon final follow-up, the client had a remarkable reduction in symptoms.

CONCLUSION

The Paleolithic diet may be used as a nutritional therapeutic protocol in those with HT with who have complications reducing weight and alleviating gastrointestinal and neurological symptoms no adverse events. Future research should be performed on larger, more diverse populations to develop population-based clinical practice guidelines. Specific areas of research, such as the long-term effects of the PD on HT, comparisons with conventional treatments, and exploring the mechanisms by which PD influences HT symptoms and markers will be beneficial to this research.
