MedlinePlus – Endocrine System

MedlinePlus - Endocrine System is a starting place for those interested in learning about common endocrine diseases, including diabetes. The section includes a medical encyclopedia and links to many outside resources for those seeking reliable basic information about endocrine disease. This MedlinePlus section is recommended for information provided by some of the most authoritative and reputable sources in the medical field, but other sites will be needed to find broader coverage of these topics.

Ease of Use

The section has intuitive navigation by A-Z topic list or body system. Each listed topic leads to a page with a brief summary of the disease and numerous links to additional information. There are also right-hand lists that allow access to the medical encyclopedia and other topics related to the condition. Because the unique nature of MedlinePlus, with its many links to outside resources, users must constantly jump from this site to others and then back again; the resulting navigation can be tedious.

Visual Design

The home page is not very inviting, having only a list of topics & systems along with a simple illustration of the endocrine system.


Users will find information of only the most common endocrine disorders. Inconsistent referencing make the reliability of each MedlinePlus page for a disease or condition variable. Topics found in the medical encyclopedia are well referenced, while this is inconsistent for disease summaries and information from linked sites. However, most links go to respected federal or specialty organization sites.


MedlinePlus clearly identifies the organizations responsible for the content, which include the National Institutes of Health, Hormone Health Network, and National Library of Medicine. Users will find that the medical encyclopedia topics have the highest reliability by listing reviewers and date of last review. Although MedlinePlus does a great job updating it's pages regularly, the currency of linked sites varies, and individual authors/editors of each topic page are not identified & only occasionally on the linked sites.
