➢ Including abnormal menstrual bleeding dysfunctional uterine bleeding (DUB) bleeding due to other causes: pregnancy, systemic disease cancer et al

Patterns Menorrhagia(hypermenorrhea) >Hypomenorrhea(cryptomenorrhea) Metrorrhagia(intermenstrual bleeding) >Polymenorrhea >Oligomenorrhea >Menometrorrhagia Contact bleeding(postcoital bleeding)

Patterns ➢ Menorrhagia(hypermenorrhea) ➢ Hypomenorrhea(cryptomenorrhea) ➢ Metrorrhagia(intermenstrual bleeding) ➢ Polymenorrhea ➢ Oligomenorrhea ➢ Menometrorrhagia ➢ Contact bleeding(postcoital bleeding)

Menorrhagia Cyclic menstrual flow,excessive in duration or amount Clots means excessive bleeding,not abnormal Gushing or open-faucet is always abnormal Causes:submucous myomas,adenomyosis, endometrial hyperplasia,malignant tumors, dysfunctional uterine bleeding

➢ Menorrhagia Cyclic menstrual flow, excessive in duration or amount Clots means excessive bleeding, not abnormal Gushing or open-faucet is always abnormal Causes: submucous myomas, adenomyosis, endometrial hyperplasia, malignant tumors, dysfunctional uterine bleeding

>Hypomenorrhea Light menstrual flow,sometimes spotting Causes:hymenal or cervical stenosis, uterine synechiae,oral contraceptives

➢ Hypomenorrhea Light menstrual flow, sometimes spotting Causes: hymenal or cervical stenosis, uterine synechiae, oral contraceptives

>Metrorrhagia Bleeding occurring at any time between menstrual periods Causes:dysfunctional uterine bleeding, endometrial polyps,carcinomas,exogenous estrogen administration

➢ Metrorrhagia Bleeding occurring at any time between menstrual periods Causes: dysfunctional uterine bleeding, endometrial polyps, carcinomas, exogenous estrogen administration

>Polymenorrhea Periods occur too frequently Usually associated with anovulation and rarely a shortened luteal phase in menstrual cycles

➢ Polymenorrhea Periods occur too frequently Usually associated with anovulation and rarely a shortened luteal phase in menstrual cycles

>Oligomenorrhea e Bleeding or slight spotting,occur at interval >35 days Amenorrhea:no menstrual period >6 month Causes: Endocrine:pituitary-hypothalamic cause,pregnancy Systemic:excessive weight loss Estrogen-secreting tumors

➢ Oligomenorrhea Bleeding or slight spotting, occur at interval >35 days Amenorrhea: no menstrual period >6 month Causes: Endocrine: pituitary-hypothalamic cause, pregnancy Systemic: excessive weight loss Estrogen-secreting tumors
