PUBERTY MENORRHAGIA
![Page 3: Puberty Menorrhagia](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f093cb1af9f880b8b4d27/html5/thumbnails/3.jpg)
DEFINITION-Puberty menorrhagia is defined as excessive bleeding occurring between menarche and 19 years.

PATHPHYSIOLOGY
• During the prepubertal years, LH is secreted primarily at night in an episodic fashion. With the progression to puberty, LH peaks increase in a pattern similar to that seen at night. The timing of these LH pulses is crucial in establishing normal ovulatory cycles. Increases in basal LH as well as immature timing of pulses result in anovulatory cycles.
![Page 5: Puberty Menorrhagia](https://reader033.fdocuments.net/reader033/viewer/2022061105/543f093cb1af9f880b8b4d27/html5/thumbnails/5.jpg)
These cycles are characterized by levels of LH and FSH secretion that are sufficient to induce follicular development and oestrogen production but inadequate to induce follicular maturation and ovulation. Thus unopposed oestrogen stimulates endometrial growth. This ultimately outgrows its blood supply and architectural support, resulting in partial breakdown and shedding in an irregular manner.

Rare causes of pubertymenorrhagia.
-von Willebrand disease
It arises from a qualitative or quantitative deficiency of von Willebrand factor (vWF), a multimeric protein that is required for platelet adhesion.

Schmidt's syndrome, also known as polyglandular deficiency syndrome, is the presence of Addison's disease and hypothyrodism in a single patient.
