Background: Endocrine disorders involve changes to glands that produce hormones. Hormones are released by these glands into the blood so they can direct the function of other tissues in the body. Researchers want to study people who may have endocrine disorders. They want to learn more about the conditions that affect endocrine glands. Objective: To study adults with a variety of endocrine disorders for research and physician education. Eligibility: Adults ages 18 and older who have an endocrine or metabolic-related disorder Healthy volunteers 18 and older Design: Participants will be screened with a review of their medical records. Participants will have a physical exam and medical history. The length of the study and the schedule will vary by participant.

They may be injected with a substance to make their organs more visible in the pictures. Tests of endocrine tissue function Consultation with other specialists Sleep study Medical photographs Participants may be treated for their endocrine disorder. This could include: Surgery. If tissue is removed during surgery, it may be studied. Radiation Medicine Participants may have genetic testing. This will be done with a small amount of blood, cells from a cheek swab, or saliva.
