Hashimoto’s thyroiditis is an autoimmune thyroid inflammation whose pathogenesis has not been fully clarified and is thought to be caused by a combination of genetic, immune and environmental factors. The disease is insidious and progresses slowly. Early Hashimoto’s thyroiditis patients have atypical symptoms that can be detected during a physical examination, but with the progression of the disease, symptoms of hypothyroidism such as enlargement of the thyroid gland, as well as chillsiness, fatigue, memory loss, loss of concentration, bradycardia, abdominal distension, and constipation can occur. Most patients with Hashimoto’s thyroiditis have normal thyroid function and mild goiter, so no treatment is needed. Those with significant hypothyroidism should be treated with thyroxine hormone replacement therapy. Patients with Hashimoto’s thyroiditis symptoms are advised to go to the hospital, and those who are diagnosed with Hashimoto’s thyroiditis should actively cooperate with the doctor’s treatment.
