Galactorrhoea
Characterised by a large amount of milky discharge from multiple ducts.
Management
- History/examination to consider cause: physiological, drugs, thyroid disorder, pituitary tumour (visual field defects/ new headaches) / prolactinoma (menstrualdisturbance/acne)
-
Check serum prolactin/TSH
- For serum prolactin the upper end of normal range is 496 mU/L in women and 324mU/L in men
- Raised prolactin levels are common (e.g. due to higher dose COCP or stress).
- In prolactinoma a very high value (over 1000 and usually several 1000mU/L) is expected.
- If a patient has a very high serum prolactin and isnot pregnant or breast feeding consider referral to Endocrinology not to breast surgery
