Hyperprolactinemia
Hyperprolactinemia — elevated serum prolactin — is the most common pituitary hormone disorder. It disrupts the reproductive axis in both men and women, causing hypogonadism, infertility, and — in women — galactorrhea and menstrual irregularity. Most cases are caused by a benign prolactin-secreting pituitary adenoma (prolactinoma) or by medications.
When to Book
Book a visit if symptoms are new, persistent, getting worse, or affecting daily life. Early evaluation often prevents complications.
Symptoms
In women: irregular or absent periods, infertility, milky nipple discharge (galactorrhea), decreased libido, and vaginal dryness. In men: decreased libido, erectile dysfunction, infertility, and — in large adenomas — headache and visual field defects from optic chiasm compression.
Causes & Risk Factors
Prolactinoma (pituitary adenoma) is the most common endogenous cause. Medications — dopamine antagonists (antipsychotics, metoclopramide), SSRIs, opioids, and certain antihypertensives — are the most frequent cause overall. Hypothyroidism and chronic kidney disease also raise prolactin through different mechanisms.
How We Evaluate
Fasting morning prolactin is measured twice to confirm elevation (stress, recent breast stimulation, or phlebotomy can transiently elevate levels). TSH is checked to exclude hypothyroidism. Pituitary MRI with gadolinium is obtained when prolactin is significantly elevated or a structural cause is suspected.
Treatment Options
Dopamine agonists (cabergoline, bromocriptine) are first-line — they suppress prolactin, shrink tumors, and restore gonadal function in the majority of patients. Cabergoline is preferred for tolerability and efficacy. Surgery is reserved for resistance to medical therapy, very large tumors, or vision compromise. Medication-induced hyperprolactinemia is managed by switching the offending drug when possible.
When It Is Urgent
Seek prompt care for sudden severe headache or acute vision changes — these symptoms in a patient with a known prolactinoma may indicate pituitary apoplexy (hemorrhage into the adenoma), a neurosurgical emergency.
Frequently Asked Questions
Do I need a referral to see an endocrinology provider?
No referral is needed at Nomi Beach Health. You can book directly with our team for hormone, thyroid, metabolic, or weight-management concerns.
How long does it take to see results from treatment?
Timeline depends on the condition. Thyroid medication often improves symptoms within four to eight weeks. Weight-loss interventions show measurable changes in four to twelve weeks. Hormone therapy timelines vary by the specific condition and individual response.
Will I need labs before my first visit?
You can come in without prior labs — we order whatever is appropriate during or after your visit. If you have recent results, bring them so we can start the conversation right away.
Are these conditions managed long-term or treated once?
Most endocrine and metabolic conditions require ongoing management rather than a single treatment. We build a follow-up schedule around your specific diagnosis and goals.
Can I be seen for weight loss even if I do not have a hormone diagnosis?
Yes. We evaluate weight holistically — including metabolic markers, lifestyle factors, and, when appropriate, medication options such as GLP-1 agonists.
