Question

Can a person live without a pituitary gland?

Answer 1

A person cannot survive naturally without a functional pituitary gland because it is the master gland regulating vital endocrine glands and processes. It secretes essential hormones like ACTH and TSH, which stimulate the adrenal cortex and thyroid gland to sustain metabolism and electrolyte balance. Without medical intervention, complete deficiency leads to fatal metabolic failure. However, with lifelong hormone replacement therapy supplying synthetic corticosteroids and thyroid hormones, an individual can manage symptoms and survive.
