5 Must Know Facts For Your Next Test

  1. The pituitary gland consists of two main parts: the anterior lobe and the posterior lobe, each responsible for different hormone secretions.
  2. Autoimmune disorders can target the pituitary gland, leading to conditions such as hypophysitis, which causes inflammation of the gland.
  3. Pituitary insufficiency due to autoimmune attack can result in secondary adrenal insufficiency, affecting cortisol production.
  4. Autoimmune-related damage to the pituitary can disrupt growth hormone levels, leading to various developmental issues.
  5. Diagnosis of autoimmune disorders affecting the pituitary often involves imaging studies like MRI and measurement of hormone levels.
