1. Amenorrhea, galactorrhea, and decreased sexual function
Hyperprolactinemia suppresses gonadotropin secretion. Women may develop amenorrhea, galactorrhea, and infertility; in men, decreased libido and erectile dysfunction are common but often overlooked.
2. Acromegaly and facial changes
Excess growth hormone causes acromegaly in adults with coarsened facial features; in children it presents as gigantism.
3. Cushing syndrome–like manifestations
ACTH-secreting adenomas can cause moon facies, a “buffalo hump,” purple striae, hypertension, and hyperglycemia.
4. Hyperthyroid manifestations
TSH-secreting adenomas may cause palpitations, heat intolerance, and hyperhidrosis without exophthalmos, and should be differentiated from primary hyperthyroidism.
5. Visual acuity decline and visual field defects
Compression of the optic chiasm can cause bitemporal hemianopia and progressive vision loss, potentially leading to blindness, and is an important surgical indication.
6. Headache
Often a pressure-like pain located in the forehead or retro-orbital region due to increased intrasellar pressure; sudden severe headache should raise concern for pituitary apoplexy.
7. Hypopituitarism
Compression of normal pituitary tissue may lead to secondary adrenal, thyroid, and gonadal insufficiency and may cause growth arrest in younger patients.
8. Other compressive neurological symptoms
Invasion of the cavernous sinus can cause ptosis, diplopia, and facial numbness; giant tumors may result in hydrocephalus.
Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes that pituitary adenoma symptoms can be insidious and may lead to facial changes, infertility, and vision loss. Subtle warning signs — such as menstrual irregularities, headache, and visual decline — should prompt timely evaluation. Early hormonal testing and MRI-based diagnosis are essential to secure the opportunity for individualized therapy, preserve organ function, and restore health.
