Q.1: can raised PRL cause secondary amenorrhoea ? Uncommon cause of amenorrhea. Elevations in prolactin may cause amenorrhea or galactorrhea. Amenorrhea without galactorrhea is associated with hyperprolactinemia in approximately 15% of women. In patients with both galactorrhea and amenorrhea, approximately two-thirds will have hyperprolactinemia; of those, approximately one-third will have a pituitary adenoma. In more than one-third of women with hyperprolactinemia, a radiologic abnormality consistent with a microadenoma (> 1cm) is found.
Q.2: Can thyroid disorders cause menst
abnormalities ? Ans: Because levels
of thyroid-stimulating hormone (TSH) are sensitive to excessive or deficient
levels of circulating thyroid hormone, and because most disorders of
hyperthyroidism and hypothyroidism are related to dysfunction of the thyroid
gland, TSH levels are used to screen for these disorders.
The most common thyroid abnormalities in women, autoimmune thyroid disorders, represent the combined effects of the multiple antibodies produced. Severe primary hypothyroidism is associated with amenorrhea or anovulation. The classic triad of exophthalmos, goiter, and hyperthyroidism in Graves’s disease is associated with symptoms of hyperthyroidism
