Treatment of hypothyroidism in special situations.

The treatment of hypothyroidism is aimed at restoring the euthyroid state. In most cases, the signs and symptoms of thyroid deficiency generally resolve, which is particularly gratifying for the treating physician and mainly, for patients. However, there may be coexisting special situations that can potentially hinder or interfere with a successful treatment, as in the case of the elderly, patients suffering from heart disease, hematological diseases or dyslipidemia, hypothyroid patients who will undergo an emergency surgery, those with chronic kidney failure, or adrenal insufficiency, among others. Besides management of hypothyroidism in time of COVID-19 is also included. Some patients may experience intolerance to treatment and others persistent symptoms of hypothyroidism even under adequate replacement therapy, requiring a special approach. Being aware of these special situations will provide benefits to the patient and will also prevent treatment failure or complications.
