Hi
@Hooked,
I've had VERY raised prolactin levels for... um... I think 30 odd years. So I may be able to shed some light.
And if there is anything you would like to ask, please do, on here or by PM.
As I understand it, normal prolactin levels are usually around 0-100 units. Lactating women can go up to 400 units.
Without medication, I run at 2000+
If your doc said 550 (a guess?) then you are a little high.
Perhaps if I tell you a little about my situ, it will help.
Irregular periods. Weight gain. Great difficulty losing weight. Aches and pains in feet, knees and tendons.
Insane food (carb) cravings.
And I really do mean INSANE. Not something that could be dealt with by normal eating.
They all started in my late teens. Then menstruation stopped completely (every cloud!).
In my 30s I finally got a doc (female) who was willing to stop bullying me to lose weight, and actually run some tests. 18 months, 2 MRI scans later, and I got a diagnosis of micro prolactinoma of the pituitary.
Basically, many tiny tumours throughout my pituitary gland. They put me on Cabergoline, which blocks prolactin production.
My periods started again (boo hiss) and I was able to lose about 1/3 of my excess weight. Then I stalled. I did feel different though. More... Um... Feminine. If that makes sense.
I asked them to increase the med dosage (to try and lose more weight), but they refused. Too much risk of side effects. My last prolactin test result was around 1200 and has been stable there for years.
I've never produced any milk (they can't understand why).
The reason you were asked about headaches is because the pituitary is right next to the optic nerve, so a swelling on the pituitary may press on the nerve = blinding pain.
If you every get that, get to a doc ASAP.
I get tendon/foot pain and hypermobile joints too, because prolactin is the hormone that softens the tendons ready to open up the pelvis during childbirth. So my tendons are permanently soft and stretchy.
Please do not be alarmed at any of this.
If your levels are just above normal, you have nothing to worry about.
And I have lived with this for decades, reasonably happily.
Please, ask anything, if you like.
(The vast majority of prolactinoma - tumours on the pituitary gland - are benign. I actually knew mine was benign long before my doc did. I just went online and read up about it. Worked out that the symptoms I had matched this thing exactly, worked out that I had had the symptoms at least 20 years at that point, and concluded that if it had been cancerous, I would have already been dead! It was a bit of a relief.
