Endocrinology is the study of hormones. Hormones are found in all organisms with more than one cell which means they are found in both plants and animals. And hormones influence or control a wide range of activities within our bodies such as growth, development, puberty, level of alertness, sugar regulation and appetite, bone growth etc. Problems with hormones and the way they work have a significant impact on major diseases such as diabetes, thyroid and pituitary conditions, some sexual problems, some neurological problems, appetite and obesity, bone problems, cancer, etc.

Endocrinologists can help patients manage these medical problems in a variety of ways including dietary recommendations and medication.
