Hypopituitarism

★ CMTO Exam Focus

Deficient secretion of one or more anterior pituitary hormones, resulting in downstream deficiency of target gland hormones. Because the anterior pituitary regulates GH, TSH, ACTH, LH, FSH, and prolactin, hypopituitarism produces a complex, multi-system clinical picture depending on which hormones are deficient. Pan-hypopituitarism refers to deficiency of all anterior pituitary hormones. The most common cause is pituitary adenoma (mass effect), followed by pituitary surgery, cranial radiation, and Sheehan syndrome (postpartum pituitary necrosis from massive hemorrhage).

Recognition

  • GH deficiency (adults): Reduced muscle mass, increased central adiposity, fatigue, decreased exercise tolerance, reduced bone density
  • TSH deficiency (central hypothyroidism): Fatigue, cold intolerance, constipation, dry skin, weight gain — same clinical picture as primary hypothyroidism
  • ACTH deficiency (secondary adrenal insufficiency): Fatigue, hypotension, nausea, weight loss. Key distinction: NO hyperpigmentation (unlike primary Addison disease, where elevated ACTH causes pigmentation)
  • Gonadotropin deficiency (LH/FSH): Amenorrhea, loss of libido, sexual dysfunction, infertility, osteoporosis
  • Prolactin deficiency: Inability to lactate postpartum (Sheehan syndrome)
  • Mass effect symptoms: Headache and bitemporal hemianopsia (visual field defects from pituitary adenoma compressing the optic chiasm)
  • Multiple hormone replacements (levothyroxine, hydrocortisone, GH injections, sex hormones) on the medication list

MT Relevance

  • ACTH deficiency (secondary adrenal insufficiency) is the primary safety risk — cortisol-dependent stress response is compromised. Sessions should not be excessively physically or emotionally taxing. Confirm the client has taken their hydrocortisone on the day of treatment.
  • Adrenal crisis risk: Sudden severe hypotension, nausea, confusion, loss of consciousness — do not mistake for vasovagal syncope. Call 911
  • Orthostatic hypotension: Clients with ACTH deficiency have baseline low blood pressure — slow repositioning is essential
  • Osteoporosis/reduced bone density: GH deficiency reduces bone density. Avoid deep pressure over the spine, ribs, and pelvis. Adjust to tissue tolerance
  • Fatigue: Very common — keep sessions within the client's comfortable energy envelope. Avoid overstimulating the nervous system
  • Hormone replacement complexity: Clients on multiple hormonal replacements — review medications carefully at each visit. Some affect coagulation, tissue quality, or cardiovascular response
  • Pituitary surgery history: If the client has had transsphenoidal surgery or cranial radiation, be aware of any specific head/neck restrictions from their medical team

Required Actions

  • Adrenal crisis signs (severe hypotension, confusion, nausea, collapse): Call 911 — do not dismiss as vasovagal syncope
  • New visual changes (visual field loss, double vision) in a client with pituitary history: Urgent referral — may indicate tumor growth or recurrence
  • Client has not taken hydrocortisone: Postpone the session

Key Takeaways

  • Hypopituitarism is deficiency of one or more anterior pituitary hormones — pan-hypopituitarism affects all
  • ACTH deficiency (secondary adrenal insufficiency) is the primary safety risk — cortisol-dependent stress response is compromised. Know adrenal crisis signs
  • GH deficiency causes fatigue, decreased muscle mass, and osteoporosis — reduce pressure and pace sessions to tolerance
  • Clients are often on multiple hormone replacements with various MT implications (hypotension, tissue fragility, coagulation effects)
  • Distinguish from primary endocrine failure: no hyperpigmentation in secondary adrenal insufficiency, and the deficit is central (pituitary) not glandular
