Summary
Rising hormone levels inhibit further secretion, as with thyroxine and TSH.
In depth
Hypothalamus (TRH), pituitary (TSH), thyroid (T3 and T4) is an example axis; high T4 inhibits TRH and TSH. Others: cortisol (CRH-ACTH-cortisol). Most hormones maintain homeostasis this way.
Negative feedback keeps hormone levels stable. Loss of feedback leads to over- or under-secretion. Many disorders arise from gland failure or tumours.
Common mistake: negative feedback does not mean 'bad'; it means the output reduces the stimulus.
