Answer #1

Pituitary hyperplasia can cause excess secretion of growth hormone. When it occurs before the epiphyseal closure, it causes gigantism and when it occurs after the epiphyseal closure, it causes acromegaly.

Effects on anatomy:-

1. Acromegaly

  • Thick lips
  • Changes in tongue size and shape
  • Protruding jaw
  • Enlarged hands and feet
  • Enlarged glands in the skin (sebaceous glands)
  • Height of the person is unaffected

2. Gigantism

  • Prominent forehead
  • Protruding jaw
  • Thickening of facial features
  • Widely spaced teeth
  • Increased height for the age of the child.

Effects on physiology:-

1. Acromegaly

  • Decreased muscle strength
  • Easy fatigue
  • Excessive sweating
  • Headache
  • Hoarseness of voice
  • Joint pain
  • Limited joint movement
  • Sleep apnea
  • Excessive hair growth in females

2. Gigantism

  • Delayed puberty
  • Double vision or difficulty with side vision
  • Headache
  • Increased sweating
  • Irregular menstruation in females
  • Weakness
