The detection or exclusion of endocrine disorders requires a targeted diagnostic process with a detailed medical history, physical examination, and laboratory diagnostics. The treatment of endocrine diseases also necessitates the individualization of measures. The Practical Handbook for Endocrinologists provides, unlike traditional textbooks, a symptom-oriented approach to diagnostic pathways and therapeutic decisions using numerous algorithms and tables. The book serves as a guide not only for the endocrinologically experienced expert but especially for the physician who is less experienced in endocrine issues, offering support in daily practice.
