Hormone levels are held steady by feedback loops

Rising levels of a hormone usually switch off the signals that produced it Most endocrine axes run on negative feedback. The hypothalamus drives the pituitary, the pituitary drives a gland, and the gland's hormone feeds back to quiet the first two. If thyroid hormone rises, for instance, it suppresses thyroid stimulating hormone from the pituitary.
