This document discusses abnormal uterine bleeding (AUB). It begins by defining normal menstrual cycles and explaining the hormonal regulation of menstruation. It then describes different types of abnormal bleeding patterns seen in AUB, including menorrhagia, metrorrhagia, and oligomenorrhoea. Organic and functional causes of AUB are outlined. The document focuses on the pathophysiology, endometrial changes, and management of anovulatory and ovulatory dysfunctional uterine bleeding. Diagnostic tests for AUB and differential diagnoses for adolescents and reproductive-aged women are also reviewed. Treatment options for AUB include medical therapies like hormones and lifestyle modifications, as well as surgical interventions.

2. Normal Menstrual Cycle
Menstration is a cyclic physiological phenomena
starting at the age of Menarche (10-12years) till
establishment of Menopause (45-55 yrs).
It is regulated by hypothalmo-pituitary- ovarian
hormones secreted in pulsatile and cyclic
pattern.
Also influenced by endometrial response top
these (E& P ) hormones and coagulation
cascade.
Cycle lenghth-21-35 days , mean menstrual
blood loss -30-40 ml , duration of bleeding
(period0---2-8 days.
3. Volume of blood flow is assessed by number of pads / tampons used
whether the pads are fully/ partially soaked , presence of clots. It can
be better assessed by pictorial charts--

14. Arrest of Menstrual bleeding
# mechanisms---
1 Haemostasis by plate let plug and clot formation – starts
soon the bleeding starts and open BV are plugged .once
Blood vessels are plugged , fibrin deposition occurs ---
Fibrinolysis also go hand in hand to balance and keep the
blood loss fluid.
2.Prostaglandin Mediation – Archadonic acid and Pg
synthetase enzyme produce PGs ---pge2 –vasodilator,
PGf2a--- vaso constrictor andThromboxane – vaso
constrictor. Estrogen produce PGE2 and PGF2a in ratio of
1:1 in proliferative phase ; while Progesterone produce
PGE2 and PGF2a + thromboxane (a2) in a: 2 ratio in
premenstrual phase so balance is shifted towards
vasoconstricton which help in contrl of bleeding.
15. Arrest of Menstrual bleeding
--
3.Tissue Repair --- starts from the mouths of
open endometrial glands in the denuded
areas , endothelium out grows and covers the
raw area under the influence of Epithelial
Growth Factor ( EGF) and blood vessels
regrow due toVascular endothelial Growth
Factor (VEGF).Thus the raw area of
remaining basal endometrium is completely
epithelized under Estrogen effect.
16. Abnormal uterine bleeding
Organic Causes Functional Uterine bleeding(DUB)
Deseases Of GenitalTract—
Pregnancy related irregularity
Abnormal Bleeding from GenitalTract without
any demonstrable organic cause.
IUCD Related Irregularity Diagnosis is made by excluding organic cause
.
Benign Conditions-- Altered Hypothalamus-pituitary-ovarian-
Fibroids, its polyps Function
Endometriosis (external;
Adenomyosis
Altered endometrial response to Sex
Hormones
Endometrial Polyp altered proprtion of estrogen and progestrone
production and their effect on Endometrial
Malignant Lesions phasing may cause DUB.
Endometrial
Cervical
Vaginal
Ovarian
17. Menstrual Patterns IN DUB
Regularity—1. regular ,2 irregular , absent.
Frequency---1. frequent < 21 days, 2. Normal
21-35 days,3. Infrequent >35 days.
Duration– Normal 2-8 days , Prolong > 8 days
.shortened <2 days .
Volume – normal 20 -80ml , Heavy > 80
ml, Light < 15 ml
18. Terminology
Menorrhagia –Regular cycle with prolonged or
heavy flow.
Polymenorrhoea – frequent cycles but normal
bleeding .
Poly menorrhagia – frequent cycles with heavy
bleeding .
Metrorrhagia ----Inter menstrual Bleeding .
Oligomenorrhoea—Infrequent cycle with normal
bleeding .
Hypomenorrhoea—Regular normal cycle with
light Bleeding.
20. Anovulatory DUB
In some adolescent girls and perimenopausal women,
Ovarian follicles develop(FSH Stimulation) and
produce estrogen in variable amount leading to
proliferation of endometrium .
Dominant follicle may not develop due to insufficient
LH surge – no ovulation—no development of carpus
Luteum ---no progesterone --- no secretary changes in
endometrium ; estrogen still secreted by follicles
(grannulosa cells) .
Unopposed estrogenic Stimulation and some time
hyper ( super threshold ) level of estrogen results in
over growth of endometrium(hyperplasia) ----resulting
in prolonged cycle and increased blood loss during
period.
21. Anovulatory DUB
When endometrium over grow s its blood
supply , lack of progesterone causes
decrease PGE2 vasodilators initially and
Avascular necrosis of functional
endometrium occur , endometrium is shade
off Lack of vasoconstrictors--- PGf2a and
thromboxane results in excessive blood loss
which is pain less and prolonged for 20-
30days (As irregular shading of endometrium
continues for such a long time ).
Persistent Follicles under go the formation of
follicular cysts.
22. Anovlatory DUB Metropathia Hamorrhagica
Accounts for 80% of DUB; at Pubertal and perimenopausal age
,Patient has variable period of amenorrhoea followed by
prolong, heavy , painless bleeding .
Prroplonged Un opposed Estrogen
Proliferative Endometrium
Simple Hyperplasia
Complex Hyperplasia
Complex Hyperplasia with Atypia
Adenocarcinoma
23. Endometrium in Metyrpathia
Haemorrhagica
Usually reveals cystic hyperplasia( simple
hyperplasia with out atypia) called swiss
cheese appearance .
- Hyperplastic glands and strauma.
- Cystic or irregularly dilated glands.
- Thick walled , tortuous , dilated spiral
arterioles and veins.
- Infarction and thrombosis of blood vessels.
- Necrosis of functional endometrium .
25. Progress And Course of Metropathia
Haemorrhagica
Incidence of malignancy ---
simple cystic Hyperplasia---1%
Complex hyperplasia with atypia---29%
It is further increased in perimenopausal
women who are obese, diabetic,on E2 therapy,
hypertensive and relatively infertile , H/O Ca
endometrium in family and had PCOD.
Young Girls who are obese with or with out PCOD
are prone to have metropathia Haemorrhagica
of early changes which are reversible with
progesterone / Ocs therapy.
30. The endometrial adenocarcinoma in the polyp at the left
is moderately differentiated, as a glandular structure
can still be discerned. Note the hyperchromatism and
pleomorphism of the cells, compared to the underlying
endometrium with cystic atrophy at the right.
31. Threshold Bleeding
This is often seen in peri menopausal women .
There is insufficient development of ovarian
follicles resulting in low estrogen level not able
to sustain endometrium or trigger LH surge ( no
ovulation ).
Such women can have prolonged and excessive
bleeding due to absence of progesterone and
lack of PGF2a and thomboxane.
Bleeding PV in these women can be controlled
with cyclic E2 + P CombinationTherapy as both
are at low level .
32. Ovulatory DUB
More common in women of reproductive age
group (21-40 years ) .
Accounts for 20% cases of DUB.
Patient usually present Cyclic excessive
bleeding / premenstrual spotting.
Periods are associated with Pain .
33. Idiopathic Adulatory
Menorrhagia (DUB )
An alteration in ratio of PGE2 and PGF2a ( vaso
dilator : vaso constrictor )occurs in some women
despite of ovulation and normal progesterone
production from carpus luetium .
Increase in PGE receptors in endometrium ,
reduction in thrombxane production and
increased fibrinolytic activity has also been
demonstrated in these women .
PgF2a causes Dysmenorrhea.

In adequate Functioning of carpus luteum can
result in--
-- in sufficient and erratic production of
Progesterone.As well as alteration in the
ratio of PGE : PGF
---resulting in irregular and patchy screttory
changes in the endometrium
Both pathophysiological deficit leads to
irregular ripening and or irregular shading
of endometrium .

54. Progesterone Intra Uterine System
The commonly used progesterone is
Levonorgestrel bearing IUCD (LNG-IUS).
It can reduce the blood loss up to 90%.
It is effective contraceptive too( 5years).
It is as effective as endometrial ablation avoiding
surgical management like hysterectomy.
LNG-IUS delivers 20 ug levonorgestrel daily to
endometrium .
It causes glandular atrophy and stromal
decidualization.
It has minimal action on Hypothalmo-pituitary –
ovarian axis.
Nosystemic side effect.
56. Surgical Treatment of DUB
Conservative
-Dilatation & Curretage—routine / Fractional
-Endometrial ablation.
Redical
-Hysterectomy
Total
Pan Hysterectmy.
Total with unilateral salping overiotomy/
shalpingo oophrectomy.
57. Endometrial Ablation
Ablation means == elimination
1. Indication
failed medical therapy .
Young women desires to preserve uterus.
Poor surgical risk for hysterectomy (non
carcinoma lesion of endometrium)
2. Contra Indications
Desire for fertility
Large uterine cavity -- <12cm.
Endometrial hyperplasisia with Atypia.
Suspected malignancy of genital tract.
Multiple or large fibroids/ nonfunctional ovarian
cysts.
63. Disadvantages of !st generation Ablation
Technique.
Require skilled person.
Require long training.
Require general anasthesia.
More chances of uterine perforation and fluid
over load.
Long term results of Ablation---
30% women remain amenorrhi0ec .
40-50 % women have reduced bleeding during
their menstrual periods.
10-20 % women reqquire hysterectomy due to
failure e.g. no relief from bleeding.
64. Hysterectomy Indications
Endometrial hyperplasia with atypia.
Failed Medical therapy in women over the
age of 40-45.
Failed endometrial Ablation.
Other pelvic pathology that needs surgery

66. Key Points
AUB can be due to organic disease or functional
disorder.
It can occur in any age group –adolescent/ reproductive
or perimenopausal .
Dub is diagnose by exclusion of organic lesions by
clinical and investigatory methods.
Drug Rx (non hormonal –then hormonal should be given
first as majority of cases will get desired response.
LNG –IUS has revolutionized the medical management
and has reduced the need of surgical Rx.
If medical management fails – endometrial ablation can
be done.
If there are contra indication for Ablation and or it fails
hysterectomy can be done in Perimenopausal women .
Rx of DUB Is to Be Individualized Approach
