What a low Prolactin can mean
- Generally not clinically actionable in non-lactating individuals.
- Postpartum lactation failure — can suggest Sheehan's syndrome.
- Hypopituitarism — broader pituitary failure.
When to discuss with a doctor
Persistently elevated prolactin with symptoms (irregular periods, galactorrhoea, infertility, headache, visual changes) warrants endocrinology evaluation and pituitary MRI when very high. Mild elevation in the context of medication should prompt review with the prescribing clinician. Always check TSH alongside.
