Does bulimia affect hormones?

Why does anorexia cause low estrogen?

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).

Can bulimia mess up your thyroid?

We hypothesize that binge-purge behavior may transiently increase thyroid indices and, consequently, metabolic rate in patients with bulimia nervosa. Furthermore, decreases in T3 following abstinence may be related to diminished caloric consumption or may reflect hypothalamic-pituitary dysregulation in these patients.

Can malnutrition cause hormonal imbalance?

Hormonal imbalance can occur as young as age 30 and may be a result of not only aging, but also lifestyle choices, such as a poor diet and lack of exercise.
