About the department

The department of endocrinology and diabetology at PAN Clinic Cologne deals with the detection and treatment of hormonal disorders and diseases of the endocrine organs. The hormonal diseases can affect many organs and lead to various pathological conditions. That is why doctors from the department cooperate with other medical professionals such as gynaecologists, urologists, geneticists, and reproductive medicine specialists to provide comprehensive diagnoses and treatment to patients. Furthermore, the department works closely with the Hormone Center Cologne. Thanks to this cooperation, doctors and patients have access to qualified partners in all matters relating to endocrinology, the study of hormones. The departments combine the latest treatment guidelines with many years of clinic experience.

Individually and taking into account all the needs of the patient, the department сarries out diseases of all endocrine organs, including the pituitary gland, hypothalamus, thyroid gland, adrenal glands, testicles and ovaries. Particular attention is paid to treating type 1 and type 2 diabetes mellitus.
