Endocrinology (Greek ἔνδον endon = "inside" and κρίνειν krinein = "to secrete", "to secrete") is the study of the morphology and function of endocrine glands and hormones as well as their regulatory and action mechanisms (from Pschyrembel Clinical Dictionary).

As endogenous signalling substances, hormones mediate communication between different organs in the body and regulate numerous metabolic processes. Important processes and functions that are controlled by hormones include human growth, sexual development and the development of sexual maturity, the regulation of mineral and water balance, and much more. New findings show that hormones also regulate the energy balance and thus body weight.

These are complex control circuits and signalling systems in which numerous components are involved. If there are disruptions within these hormone systems, normal metabolic processes and developmental processes can no longer function properly or at all. The speciality of endocrinology deals with the formation and mode of action of hormones and their disorders, which are the cause of certain clinical pictures.

Hormonal processes play a central role in the development of children and adolescents. It is therefore very important that disorders are recognised in good time and treated in an age-appropriate manner in order to avoid secondary diseases as far as possible. Endocrine disorders in children and adolescents differ from those in adults and require specialised treatment by paediatric endocrinologists. Our staff work in an interdisciplinary team to provide the best possible treatment for children and adolescents with endocrine disorders and to support them in their further physical development.
