Endocrinology is the study of the glands and hormones of the body as well as their related disorders. Clinical endocrinology encompasses a range of diseases from the very common such as diabetes mellitus to rare disorders such as pituitary diseases. Endocrinology also comprises the study of molecular and physiological action of hormones. The section is associated with the Hormone Laboratory and Division of Endocrinology, Department of Medicine, Haukeland University Hospital. The Section for Endocrinology aims at using a translational approach to integrate molecular and clinical endocrinology.

The main research projects are

1. Molecular endocrinology with emphasis on gene regulation, nuclear hormone receptors, and co-activators linked to disorders such as obesity and breast carcinoma ( Professor Gunnar Mellgren).
2. Autoimmune endocrine diseases and polyendocrine syndromes with emphasis on primary adrenal failure (Addison's disease) (Professor Eystein Husebye).
3. Hormone-related cancer with an emphasis on breast carcinoma. LC/MSMS-based developent of analyses for steroids and metabolites (Professor Ernst Asbjørn Lien).
4. Clinical studies of diabetes mellitus and autoimmune thyroid disease (Professor Sylvi Aanderud).

The section has a large registry and biobank on patients with Addison's disease which is employed in a number of experimental and clinical research projects (ROAS).
