Abnormal Menstrual Bleeding Flashcards
How long is a normal cycle? Flow? Amount?
21-35 days (up to 45)
Flow up to 7 days (average 3-5)
80ml/period (1tsp = 5ml)
What is menorrhagia?
Hypermenorrhea
What is metrorrhagia?
Intramenstrual bleeding, BTB
What is menometrorrhagia
Heavy intramenstrual bleeding
What is polymenorrhea?
Menses < q21d
What is contact bleeding
Poscoital (post-sex) or post contact bleeding
What can initiate abnormal bleeding (6)?
- infectious STI
- neoplasms (fibroids, polyps) (fibroids are the most common cause)
- endocrine/hormonal (PCOS, thyroid, obesity, menopause) (about 45% of patients with hypothyroidism have menorrhagia)
- malignancies (endometrial/cervical)
- trauma
- pregnancy (implantation/miscarriage/ectopic)
What are causes of menorrhagia (7)?
- pregnancy (must rule-out)
- infection (STI screen)
- intrauterine device
- uterine fibroids
- endometrial/cervical polyps
- hypothyroidism (TSH, fT4)
- neoplasms (pap, U/S, EMB)
dysfunctional uterine bleeding (DUB) (if all other causes have been ruled out)
What are the symptoms of menorrhagia?
- > 80-90ml/period: only 2/5 women who complain of excessive bleeding actually exceed this amount
- Menstrual bleeding >7 days
- unusually heavy bleeding (soaking through pad or tampon every hour)
- requiring change of protection at night
- menstrual flow interfering with lifestyle
- fatigue, dizziness, and/or SOB (symptoms of anemia: occurs in 2/3 of women)
How do you work up menorrhagia?
- urine pregnancy
- STI screen
- endocrine work-up (PRL, TSH/fT4, FSH, E, P)
- coagulation work-up (PT/PTT)
- PAP
- U/S (pelvic & transvaginal)
- EMB/hysteroscopy & biopsy
What are cervical disorders that can contribute to heavy bleeding (4)?
- cervicitis (acute or chronic) (chronic has thick yellow discharge with no bacteriological etiology) (requires biopsy to rule out cancer) (acute is often STI related [NG, CT, Trich])
- cervical trauma
- cervical polyps
- cervical cancer
Dx requires pap and/or biopsy
What are uterine disorders that can contribute to heavy bleeding (5)? What is the most common cause?
- polyps
- fibroids (most common cause)
- adenomyosis (endometrial glands grow into the uterine wall, creating a spongelike effect; sometimes associated with heavy, painful periods and uterine enlargement)
- endometrial hyperplasia
- endometrial cancer
Dx require pelvic U/S, hysteroscopy, EMB (endometrial biopsy)
What is a hysteroscopy?
Fibroscopic endoscope passed through the cervix to visualize endometrial cavity
What are indications for a EMB? (3)
- any abnormal bleeding
- postmenopausal bleeding
- fertility issues
What is DUB treatment? (8)
- Diet and exercise (stabilize estrogen)
- Botanicals: Chaste Tree Berry, Flax seeds
- NSAIDS (anti-inflammatory via prostaglandin inhibition and cause uterine vasoconstriction) (Ibuprofen 400 QID, naproxen 375 BID)
- Progesterone (limit & stabilize endometrial growth) (Transdermal cream: Progest or Progonol) (OCP [P alone (“mini-pill”) or combo with E]) (Mirena IUD (secretes progesterone))
- GnRH agonists (Lupron) “medical menopause” (decrease estrogen levels; expensive & prolonged use = osteoporosis)
- Dilation and Curettage (D&C) or Hysteroscopy & biopsy (procedure in which the cervix is dilated & the endometrium is removed) (H & B may be better at finding occult cancer when combined with EMB)
- endometrial ablation (procedure in which the endometrium is destroyed; 20% have hysterectomy)
- hysterectomy (when medical management fails)
What are different endometrial ablations? (3)
Treat abnormal uterine bleeding and reduce or prevent future bleeding
- Electrocautery: Approximately 90% of women experience relief of their symptoms within the first few months, with many having scant or absent menstrual periods after the procedure.
- Balloon endometrial ablation: A triangular balloon is placed into the uterus and filled with fluid and heated for several minutes destroying the uterine lining. Results are comparable to electrosurgical methods.
- Freezing of the uterine lining
There is no evidence that one method produces superior success rates
What are other names of uterine fibroids?
- leiomyomata
- leiomyoma
- fibromyoma
- myoma
Uterine fibroids are
- Most common _____ in women
- Typically benign (___% cancerous)
- Overgrowth of ________ & _________ in the wall of the uterus
- Most common indication for __________ = ____ % of _____________
- Most common solid tumor in women
- Typically benign (<1% cancerous)
- Overgrowth of muscle & connective tissue in the wall of the uterus
- Most common indication for major surgery in women = 30% of hysterectomies.
How does the risk for uterine fibroids increase with age? Race? Genetics? Hormones? Lifestyle?
Age = 35-45 (asymptomatic beforehand) Race = African American women 3x more likely Genetic predisposition Hormone = estrogen dominance Lifestyle = nulliparous (no children)
What would you expect with the bimanual exam of uterine fibroids related to firmness? Shape? Tenderness?
- firm but am vary from soft to rock hard
- irregularly enlarged
- smoothly rounded protrusions
- usually non-tender
*need to rule out pregnancy as a cause of the enlargement.
Uterine fibroids are the most common cause of ______
Abnormal uterine bleeding
What are symptoms of uterine fibroids?
- most common cause of abnormal uterine bleeding
- enlarged uterus
- pressure
- bloating
- heaviness
- constipation
- vague feeling of discomfort
- pain with vaginal intercourse
- urinary abnormalities (frequency, urgency, acute or chronic urinary retention, ureteral compression, hydronephrosis)
- pelvic pain-cramping
- backache, esp during menses
- abdominal enlargement
- infertility recurrent SAB
- pain is NOT a typical symptom.
What is the chance of a uterine fibroid being a leiomyosarcoma?
<1%
What are the chances of a uterine fibroid causing infertility? How can it cause infertility?
2-10%
- intermittent anovulation
- interfere with implantation
- compression of isthmus
- abnormal uterine blood flow
- interfere with sperm transport
- recurrent SAB
