Endocrinology is the study of hormones and their disease and covers all parts of the body. A hormone is a chemical made in one part of the body that works in another part of the body. In diabetes, for example, insulin is made by the pancreas and acts all over the body to help glucose get into cells and provide the energy they need to function normally.
Whilst Diabetes is the most common endocrine disorder, other areas where endocrinologists have specialist expertise include the thyroid, bone health and osteoporosis, disorders of calcium, reproductive hormones and fertility as well as rare hormonal diseases.
To become an endocrinologist you have to complete a 6 year medical degree, complete 4-6 years as a basic trainee and them a further 3-4 years of specialist endocrine and diabetes training.
