Endocrine medicine focuses on the hormonal system. Hormones are chemical signals that carry messages between cells of an organism. These messages affect the different organs by causing changes in the cellular metabolism. We have severlal hormonal glands in our body, including the reproductive organs (ovaries and testicles). 
Endocrine diseases develop when there are irregularities in one of the phases of the endocrine process, such as hyper- or hypo-activity of one of the hormonal glands, problems with the hormonal receptors in the cells, problems in the way the cells respond to the hormonal signals and more. Most diseases are chronic and the patient will require monitoring and treatment throughout their lives. 

The Endocrinology and Metabolism Unit at Shaare Zedek Medical Center provides comprehensive outpatient care in the clinics and also treats hospitalized patients with endocrine problems.
