Endocrinology is a medical specialty whose practitioners (endocrinologists) diagnose and treat diseases and deficiency states of the thyroid, pancreas, ovaries and other glands. These organs manufacture chemicals called "hormones" and release them into the bloodstream to regulate various body processes. Since many of the glands and their hormones function in a coordinated manner we often speak collectively of an "endocrine system."
The Society of Endocrinology describes the medical specialty in the following way:
"Endocrinology is the study of hormones. At its simplest, a hormone is a chemical messenger from one cell (or group of cells) to another. Hormones are released (secreted) in the body and have an effect on other parts of the body. The effect is to communicate with possibly distant parts of the body."
While a complete discussion of Endocrinology is beyond the scope of this specialty description, here are brief summaries of the major endocrine glands, their best-known hormones and what they do (generally, over-and under-activity of these glands would cause too much or too little of these hormone effects).
The endocrine glands can also be affected by various benign and malignant tumors, which can be causes of the over- and underactivity.
Any discussion of the endocrine glands would be incomplete without some mention of the hypothalamus -- a part of the brain that manufactures and releases various "releasing' hormones that cause their target glands to release their "stimulating" hormones. For example, Thyroid Releasing Hormone makes the Pituitary's Thyroid Stimulating Hormone happen, which in turn makes the Thyroid's thyroid hormone happen. As such, the whole system often functions like a row of dominos -- after the first one falls, the rest topple over in turn. It also illustrates the complexity of Endocrinology and the importance of balance and ensuring that the various glands work in concert with one another; throwing off one often has detrimental effects on others, while correcting such imbalances can have far-reaching benefits.
With so many glands and so many effects, a working knowledge of Endocrinology is fundamental to many other medical specialties and disciplines, including but not limited to Family and Internal Medicine, Ob/GYN, General Surgery, Urology, Psychiatry, Pediatrics and Neurology.
The endocrinologists on the Medical Staff at Chester County Hospital are all trained to diagnose and treat the various endocrine and hormone imbalances and diseases. While the more frequently-occurring gland disorders such as Type 2 Diabetes and hypothyroidism are often managed by primary care physicians, these doctors must often rely on endocrinologists for help with the uncommon problems, or the common ones that are difficult to control. Sometimes both groups may need surgeons to remove glands or their tumors. As always, inter-disciplinary cooperation is essential to crafting a unique solution for each patient.
