Background: Hypothyroidism and hypocalcemia are common after thyroid and parathyroid surgery. In this article, the authors provide clinically-oriented recommendations to help surgeons, general practitioners, internists, and endocrinologists give their affected patients adequate hormone replacement therapy. Methods: Selective evaluation of original articles and reviews that were retrieved by a PubMed search over the years 1980 to 2010, as well as of the recommendations of medical societies including the Endocrine Society (USA), the German Society for Endocrinology (Deutsche Gesellschaft fur Endokrinologie), and the American and European Thyroid Associations. Results: Important issues in L-thyroxine replacement therapy include: the selection of the hormone preparation (T4 or T4/T3), combination with iodine (yes/no), the definition of therapeutic TSH ranges (particularly after surgery for thyroid cancer), the extent of remaining thyroid tissue after goiter surgery and its significance, underlying diseases, and drug interactions. The major issues in the treatment of postoperative hypoparathyroidism are: the selection of suitable calcium and vitamin D preparations, the definition of therapeutic goals, the treatment of hypercalciuria and hyperphosphatemia, and the option of recombinant parathormone therapy. Conclusion: Effective treatment requires an appropriate choice of medication and an understanding of its pharmacokinetics as well as of the possible effects of the patient's underlying disease, comorbidities, and other medications on its absorption and metabolism.
