How does Cushing’s disease make you feel?
An eating disorder such as anorexia can impact hormonal changes due to malnutrition and self-starvation. Concentrations of sexual and thyroid hormones will fall, possibly causing osteoporosis, or weakening of the bone, over time. Hormonal changes take place in a person with an eating disorder in response to starvation.
How long can Cushing’s go undiagnosed?

Low estradiol levels are also seen in anorexia due to a lack of ovarian stimulation. However, estrogen metabolism is also altered. Estradiol, which normally undergoes 16α-hydroxylation, is channeled to 2-hydroxylation and the formation of a catechol estrogen (2-hydroxyestrone) in the undernourished state (43).
Why is Cushing’s so hard to diagnose?
The brains of women with eating disorders send signals from other regions that override the hypothalamus.” Anorexia and bulimia causes sufferers to fear eating certain foods – and this study suggests that can ultimately condition the brain to reject signals from the hypothalamus, including taste-reward and hunger …
