which gland helps regulate metabolism and can lead to weight gain if it is too low?
Every other cell depends on the thyroid to manage its metabolism. The pituitary gland and hypothalamus both control the thyroid. When thyroid hormone levels drop too low, the hypothalamus secretes TSH Releasing Hormone (TRH), which alerts the pituitary to produce thyroid stimulating hormone (TSH). The thyroid responds to this chain of events by producing more hormones.
