Hormone Dynamics and Bone Mineral Density in Anorexia Nervosa v. Hypothalamic Amenorrhea

The purpose of this study is to determine whether the hormone dynamics in women with anorexia nervosa and hypothalamic amenorrhea is related to bone loss in those populations.

Inclusion Criteria:

• Amenorrhea for at least three months (unless participating as healthy control)
• Normal TSH or free thyroxine (free T4).

Exclusion Criteria:

• Any medication known to affect bone metabolism within 3 months of the study, including estrogen and progestins. Patients receiving depot medroxyprogesterone (Depo-Provera) will be excluded from participating for 6 months after their last injection.
• Pregnant and/or breastfeeding.
• Diabetes mellitus.
