In what ways do thyroid disorders affect homeostasis?

Broadly speaking...: An under active thyroid slows metabolism. An overactive thyroid increases metabolic rate. However, other subtle or not subtle issues can occur. Low thyroid is associated with mild depression in early disease, and the hormone "prolactin, " may elevate. Heavy menstrual bleeding is common. In overactive thyroid states, menstrual bleeding may become scant, hair may become fine and brittle.
