Question: Prolactin Test

 joann9298 - Wed Oct 26, 2005 11:33 am

I Have so many symptoms to Cushings.But have not been dx with anything. I have not had a menstrual cycle since 2002 but even before that i was not regular. My left breast started lactating around August 2005. I went to the Dr. and was told this could be normal. But she put in lab for a Prolactin test on Oct.3,2005. I got the results as "normal". I also have a 3x5mm lump on my thyroid had TSH lab done 9-15-05 came back "normal". My question is what can be the cause of lactating I am not pregnant.

User avatar Dear joann9298,

In Amenorrhea- galactorrhea:
After exclusion of pregnancy, hypothyroidsm, and hyperprolactinemia, other causes of secondary amenorrhea are divided according to the level of gonadotropin-releasing hormone (GnRH) into:

- hypogonadotropic hypogonadism: also called hypothalamic amenorrhea, there is abnormalities in gonadotropin-releasing hormone (GnRH) secretion and disruption of the hypothalamic-pituitary-ovarian axis.

- hypergonadotropic hypogonadism: with early menopausal symptoms , in such patients cortisol , TSH and karyotype analysis should be done. The disease is usually due to autoimmune diorder.
ACTH and cortisol levels should be checked if cushing syndrome is suspected.
CT or MRI should be done to check for pituitary galnd lesions.

- normogonadotropic amenorrhea: Polycystic ovary syndrome (PCOS) is one of the most common cause
Females with Polycystic ovary syndromePCOS experience any of the following symptoms:
menstrual irregularity or absence of menstruation,
irregular vaginal bleeding,
pelvic pain
fertility problems
increased growth of hair
acne, oily skin, or dandruff
type 2 diabetes

Follow up with your doctor is essential.
