Therapeutic management and clinical follow-up of primary hypothyroidism after total thyroidectomy patient: case report

Abstract

Primary hypothyroidism is commonly caused by autoimmune diseases, such as Hashimoto's thyroiditis, or by surgical interventions, such as total thyroidectomy. Thyroid hormone deficiency leads to increased TSH and can result in several metabolic complications. This study aimed to describe the clinical history, from diagnosis to treatment, of a patient with primary post-thyroidectomy hypothyroidism. This is a female patient, 59 years old, underwent total thyroidectomy in 2016 after diagnosis of papillary thyroid carcinoma, with subsequent complication of primary hypothyroidism. Hormonal control was performed by exogenous levothyroxine replacement, with semi-annual monitoring. The patient also has systemic arterial hypertension, treated with Losartan, and was monitored for the need for hormonal dose adjustment and vitamin D supplementation. Therefore, the management of patients with hypothyroidism after total thyroidectomy requires continuous monitoring and therapeutic adjustment to avoid complications such as hypertension and vitamin D deficiency.
