About

Heavy periods is a significant problem in reproductive age .It affects about a third of women in the childbearing period

Any of the following is considered to be heavy menstrual bleeding (Bleeding that lasts more than 7 days,Bleeding that soaks through one or more tampons or pads every hour for several hours in a row.Needing to wear more than one pad at a time to control menstrual flow.,Needing to change pads or tampons during the night or Menstrual flow with blood clots that are as big as a quarter or larger) .

Heavy periods can be caused by organic cause as fibroids, adenomyosis, polyps or they can be dysfunctional.Dysfunctional uterine bleeding is irregular uterine bleeding that occurs in the absence of recognisable pelvic pathology, general medical disease, or pregnancy. It reflects a disruption in the normal cyclic pattern of ovulatory hormonal stimulation to the endometrial lining.

Several treatment options include: hormonal treatment as norethisterone acetate,oral contraceptive pills, gonadotrophin releasing hormone analogue. ,tranexamic acid or non steroidal anti-inflammatory drugs.

The investigators plan to do a comparative study between norethisterone acetate and tranexamic acid regarding their control of the heavy periods as well as their effect on the uterine and endometrial vasculature.

Full description

This is a Randomised controlled trial.The investigators will randomise 120 women who suffer from heavy periods (age range 35-49 years old) without organic cause (Dysfunctional bleeding ) into 2 groups, group A (60 women) : They will take norethisterone acetate 15 mg daily from day 5 to day 26 of the period for 3 months.

Group B (60 women): They will take 1 gm tranexemic acid three times daily from the start of menstrual period up to 5 days.The dose might be increased per day (Not more than 4 gm per day).

The investigators will check endometrial thickness, endometrial volume, uterine artery Doppler indices as well as endometrial and subendometrial indices before starting the treatment and 3 months afterwards.
