Brief summary: Abnormal uterine bleeding "AUB" describes all abnormal forms of menstrual bleeding which may result from several causes including anovulation, problems related to pregnancy, infections, vaginal and cervical abnormalities, uterine pathologies including benign and malignant tumors, coagulopathies, endocrine disorders, trauma, foreign bodies, systemic diseases and iatrogenic causes. AUB may be clinically presented by menorrhagia, metrorrhagia or menometrorrhagia. It's the most common complaint for the reproductive age females and accounts for 33% of female patients referred to gynecologists

Detailed description: Menorrhagia, if repeated, causes a decrease in iron reserve and anemia and subsequently, anemia causes psychological and cardiac complications and dysfunction in other organs. So, paying attention to menorrhagia and its treatment can lead to lower morbidity in reproductive aged women. It is worth noticing that most of the iron deficient anemia morbidities are the result of more than 60 ml bleeding per cycle.

The evaluation of the actual bleeding volume is not an easy task because women's evaluation of their own bleeding volume is not reliable. 25% of the women who consider their bleeding level as high had menstrual bleeding less than 35 ml. The estimation of blood loss volume was done based on the number of pads or tampons soaking per day or per cycle. The patient's estimations of the bleeding volumes are not accurate and reliable because they are not well aware of the normal range of bleeding and their evaluations are inexact.

Ideally, a noninvasive investigation is preferred to an invasive one and also an economical investigation preferred to an expensive one; this applies equally to affluent countries and third world, that is why ultrasonography by any modality if available is considered to be a noninvasive procedure to investigate uterine lesions rather than hysteroscopy as a preliminary step .

Various imaging techniques are used to enable the precise localization and characterization of uterine pathology. Currently, the main diagnostic tools for AUB include ultrasonography and diagnostic hysteroscopy.

Menorrhagia is defined as complaint of heavy menstrual bleeding over several consecutive cycles. The upper limit of monthly bleeding is 80 ml per cycle, which is 2 standard deviations from the mean (mean menstrual bleeding per cycle is 36 - 52ml).

Worldwide use of hormonal therapy is based on the wrong assumption that menorrhagia happens because of imbalance in hormones and an ovulatory cycle, but the fact is most of the women with abnormal bleeding show no evidence of hormonal imbalance and based on some studies 95% have regular ovulatory cycles.

Antifibrinolytic medications, such tranexamic acid, function by inhibiting the breakdown of fibrin and are useful in the management of individuals with persistent AUB. It has been demonstrated that they can cut bleeding in these patients by 30 to 55%. For the treatment of acute AUB, experts advise utilizing tranexamic acid intravenously (IV) or orally.

In another study, the treatment of menorrhagia, by both mefenamic acid and tranexamic acid.they were beneficial in controlling menstrual blood loss with significant decrease in dysmenorrhea Minor side effects like epigastric pain, nausea, vomiting was more frequent in mefenamic acid group. Acceptability rate was high in both groups
