From the Guidelines

The pituitary gland produces several crucial hormones, including Growth Hormone (GH), Adrenocorticotropic Hormone (ACTH), Thyroid-Stimulating Hormone (TSH), Follicle-Stimulating Hormone (FSH), Luteinizing Hormone (LH), Prolactin, Antidiuretic Hormone (ADH or vasopressin), and Oxytocin, which are essential for regulating various bodily functions.

Pituitary Hormones and Their Functions

The main pituitary hormones and their functions are:

  • Growth Hormone (GH): regulates growth and metabolism
  • Adrenocorticotropic Hormone (ACTH): stimulates the adrenal glands to produce cortisol
  • Thyroid-Stimulating Hormone (TSH): regulates the production of thyroid hormones
  • Follicle-Stimulating Hormone (FSH): essential for reproductive processes
  • Luteinizing Hormone (LH): plays a crucial role in reproductive processes
  • Prolactin: involved in lactation and reproductive processes
  • Antidiuretic Hormone (ADH or vasopressin): regulates fluid balance
  • Oxytocin: involved in social bonding, reproduction, and childbirth These hormones are released by the pituitary gland in response to signals from the hypothalamus and other parts of the body, allowing the pituitary to orchestrate complex physiological processes throughout the body 1.

Importance of Pituitary Hormones

Understanding these hormones is essential for diagnosing and treating various endocrine disorders, as they control crucial processes such as growth, metabolism, stress response, reproduction, and fluid balance. The pituitary gland, often called the "master gland," plays a vital role in maintaining overall health and well-being.

Clinical Implications

In clinical practice, knowledge of pituitary hormones is crucial for managing conditions such as pituitary adenomas, which can disrupt hormone production and lead to various symptoms and complications 1. A multidisciplinary approach to care, including experts from pediatric and adult practice, is essential for optimizing the management of pituitary adenomas and improving health outcomes in children and young people 1.

From the Research

Pituitary Hormones

The pituitary gland secretes several essential hormones, which can be categorized into two main groups: anterior pituitary hormones and posterior pituitary hormones.

  • Anterior pituitary hormones include:
    • Growth hormone
    • Prolactin
    • Thyroid-stimulating hormone
    • Follicle-stimulating hormone
    • Luteinizing hormone
    • Adrenocorticotropic hormone
    • Melanocyte-stimulating hormone 2, 3, 4, 5
  • Posterior pituitary hormones include:
    • Oxytocin
    • Antidiuretic hormone 2, 3, 5

Regulation of Pituitary Hormones

The secretion of pituitary hormones is regulated by the hypothalamus, which stimulates the release and inhibition of these hormones 2. The hypothalamus-pituitary axis plays a crucial role in regulating lactation-related hormones, such as prolactin, growth hormone, and estrogen 6.

Functions of Pituitary Hormones

Pituitary hormones are essential for various physiological functions, including:

  • Growth and development
  • Reproduction
  • Metabolism
  • Stress response
  • Lactation 2, 4, 5, 6
