It is not accurate to say that stimulating the pituitary gland can grow taller. Because the pituitary gland is multi-faceted, its role is mainly to secrete various hormones and participate in human metabolism and development, and the pituitary gland secretes growth hormone, which is related to height. In patients with growth hormone deficiency, supplementation of growth hormone can make the body grow taller. For other reasons, such as physical growth retardation or other drugs or diseases that cause non-growth hormone deficiency, stimulating the pituitary gland and supplementing with growth hormone is not effective. In addition, in patients who are not deficient in growth hormone but are not tall, mainly due to genetic reasons, stimulation of the pituitary gland is also ineffective.
