What Causes Elevated Prolactin Level In An Adolescent?

Hello, My 19 years old son has elevated Prolactin level 27.7 (range 2.2-18.5). He also did the lab work for : Estradiol, Testosterone, LH, T4, T3, TSH, Glucose, Lipid Panel, Beta HCG, Comprehensive Metabolic Panel and everything was normal. Would you please advise what this elevated Prolactin level could be? What other tests he should do to get to the bottom of it? My son is vegan but he eats nutritious food, the last time he checked his B12 it was normal. Thank you very much!

Hello dear
Following are causes of high prolactin levels-
1. Physiological: Chest wall stimulation, Sleep, Stress
2. Pituitary tumor
3. Prolactinoma and Acromegaly
4. Chronic renal failure
5. Hypothyroidism
6. Cirrhosis
7. Pseudocyesis
8. Epileptic seizures
9. Drug induced: like methyl dopa, reserpine, cimetidine

But in the absence of any symptoms, you should repeat test ind some other lab after some time.
Ask for to do pooled prolactin level.
If necessary do xray/MRI/CT scan of brain to exclude brain tumor.

Consultant with best endocrinologist in your area if condition will aggravate.

Hope this may help you.
Take care
