Disorders of Menstruation Lecture Notes

Disorders of Menstruation

  • Concepts apply to trans people who menstruate.

    Review of the Menstrual Cycle

  • Part 1

  • Controls female reproductive physiology.

  • Cycle length is variable (21-40 days, average 28 days).

  • Women menstruate ~360-400 times from menarche to menopause.

  • Every cycle ~30-90 mL blood is shed.

  • Phases:

  • Follicular (Proliferative) Phase

  • Ovulatory Phase

  • Luteal (Secretory) Phase

  • Menarche:

  • Start

  • Any age: 10-14 years old, average 12

  • Based on genetics and environment

    Hypothalamic-Pituitary-Ovarian (HPO) Axis

  • Dynamic relation between hypothalamus, anterior pituitary, and ovary.

  • The rate and amplitude of GnRH pulses from the hypothalamus determine which hormone is released by the pituitary.

  • Hypothalamus releases GnRH.

  • Anterior pituitary produces LH, FSH

  • Ovary produces estradiol, inhibin, and progesterone.

  • Negative feedback loops: estradiol, inhibin, and progesterone inhibit hypothalamus and anterior pituitary.

  • Day 1: menses start.

  • Day 7: one follicle releases a dominate to grow.

  • Follicle and estrogen are stimulating LH hormone

  • Day 13: LH surge, releasing of mature egg from ruptured follicle.

  • Day 14: ovulation.

  • Day 21: corpus luteum grows until 21 days and makes progesterone.

  • Corpus luteum dies at day 28.

  • Low levels of estrogen and progesterone

    The Menstrual Cycle - Progesterone drop

  • As the progesterone level drops:

  • the corpus luteum begins to degenerate;

  • the endometrium begins to break down, its cells committing apoptosis;

  • the inhibition of uterine contraction is lifted, and

  • the bleeding and cramps of menstruation begin.

    The Menstrual Cycle - Study

  • 2019 study (n= 612, 613)

  • Mean follicular phase length: 16.9 days

  • Mean luteal phase length: 12.4 days

  • Mean cycle length decreased by 0.18 days and mean follicular phase length decreased by 0.19 days per year of age from 25 to 45 years

  • Mean variation of cycle length per woman was 0.4 days or 14% higher in women with a BMI of over 35 relative to women with a BMI of 18.5–25

  • Between women, the follicular phase can range in length from days to weeks.

  • Thus, how long the follicular phase is for a particular individual determines menstrual cycle length.

  • Corpus luteum only viable for 14 days unless pregnancy occurs.

  • Egg is only viable for 24 hours after being released from follicle.

  • Variation:

  • Health and genetics

    Dysmenorrhea

  • Part 2

    Approach to Assessment of Patients with Pelvic Pain

    Lower Abdominal or Pelvic Pain

  • Pain can vary from mildly irritating to incapacitating

  • Pain is one of the most common problems affecting women of reproductive age

  • Pain may reflect pelvic disease but may also reflect non-gynaecological disorders that refer pain to the pelvis

  • Acute Pelvic Pain: Pain lasts < 3 months

  • Chronic Pelvic Pain: Pain lasts ≥ 3 months

  • Pharmacists are well-positioned to triage patients presenting with pelvic pain as a chief complaint and educate them on evidence-based therapies as well as when medical care should be consulted.

    Pelvic Pain Causes

  • Dysmenorrhea and endometriosis are the two most common causes.

  • Focus of lecture will be on dysmenorrhea, it is vitally important to understand (and be able to rule out) the other conditions that can present similarly

  • Cyclic pelvic pain

  • Dysmenorrhea

  • Endometriosis

  • Mittelschmerz (mid-cycle pain during follicle rupture)

  • Noncyclic pelvic pain

  • Pelvic inflammatory disease

  • Ruptured or hemorrhagic ovarian cyst, endometrioma, or ovarian torsion

  • Ectopic pregnancy

  • Endometritis

  • Acute growth or degeneration of uterine myoma

  • Threatened abortion

  • Pelvic congestion syndrome

  • Adhesions and retroversion of the uterus

  • Pelvic malignancy

  • Vulvodynia

  • Chronic pelvic inflammatory disease

  • Tuberculous salpingitis

  • History of sexual abuse

    Condition Overview - Dysmenorrhea

  • Dysmenorrhea is the most common gynecologic problem among adolescent and young adult women.

  • Occurs 93% of women

  • Goes down at more birth

    Dysmenorrhea Classification

  • Primary Dysmenorrhea

  • Women goes a die after

  • Irregular preggo birth pattern

  • No ovulation occurs

  • Older individuals

  • No obvious family history

  • Cause of young

  • Strong pain, just no family history, random

    Impact on Quality of Life

  • Dysmenorrhea is the leading cause of school absenteeism and lost working hours among adolescent girls and young women.

    Did You Know?

  • Despite its high prevalence and severity, most women do not seek medical care for this condition, so it remains commonly undertreated.

  • Treatment has the potential to improve quality of life and decrease time lost from school or work.

  • 6% of adolescents receive medical advice on dysmenorrhea treatment, while 70% self-treat.

    Primary Dysmenorrhea Etiology

  • Prostaglandins

  • Leukotrienes

  • Nitric oxide?

  • Vasopressin?

  • Endometriosis is of PG related to pain

  • NSAIDS to control PG related pain

  • Lysing contributes 3- Loot

  • 2.4 times highs in women with dysmenorrhea

    Clinical Presentation

  • Cyclic pain with menstruation

  • Range of symptoms

  • Lower mid-abdominal pain or cramping

  • Nausea/vomiting

  • Dizziness

  • Diarrhea

  • Headache

  • Pain occurs a few hours before or just after menstruation begins and lasts 48-72 hours.

  • Pain is most intense over lower abdomen but may radiate to the back & inner thighs.

    Role of Other Factors

  • Risk Factors

  • Young age (<30)

  • Nulliparity

  • Early menarche

  • Smoking

  • Stress

  • Positive family history

  • Protective Factors

  • Exercise

  • Higher parity

  • Use of hormonal contraceptives, especially if they have not had a pregnancy or are on birth control

  • Early period

    Minor Ailment Service Framework

  • Patient requests assistance with a complaint

  • Is the RPh competent & knowledgeable in managing the complaint?

  • Is RPh intervention in the best interest of the patient?

  • Is the ailment within the scope of RPh?

  • (If no to one or more) -> Refer patient to another HCP

  • (If yes to all) -> Does patient consent to the minor ailment service

  • (If no) -> OTC consult

  • (If yes)->

    • Evaluate the situation
    • Collect history of presenting complaint, patient's health & medication history
    • Collect
    • Offer a private space for consultation
    • Verify patient's self-diagnosis
    • Assess
    • Use shared decision-making to develop a care plan
    • Plan results in ≥1 of the following:
      • Referral
      • Wait-and-see approach
      • Prescribe drug and/or recommend non-pharm therapy
    • Implement
      • Issue the Rx (if applicable)
      • Advise patient of option to fill elsewhere
      • Educate patient on care plan
      • Documentation & notification of patient's PCP should occur in a timely manner if drug therapy is initiated to ensure continuity of care
    • Establish monitoring parameters
    • Schedule and complete follow-up to evaluate safety & efficacy of care plan
    • Refer to another HCP as required

    Collect Questions

  • Obtain demographic info – patient’s age

  • Obtain history on presenting illness – Symptoms over a series of different menstrual cycles

    • Onset of pain, location of pain, type/intensity of symptoms help you to rule out if it is primary or secondary dysmenorrhea.
  • Obtain patient history information

    • Medical and gynecologic (menstrual, sexual, preg) history
    • Medication history
    • Medication allergies or sensitivities
    • Social history

    Dysmenorrhea Classification

  • Characteristic: Primary Dysmenorrhea vs Secondary Dysmenorrhea

  • Age at onset:

    • 6-12 months after menarche but typically within 2 years after menarche (13-17 years of age) vs Variable but at least 2 years after menarche; (typically mid-late 20s or older or pain begins after years of normal cycles)
  • Cause:

    • Idiopathic vs Associated with pelvic pathology
  • Menses:

    • Regular – normal blood loss vs Irregular – menorrhagia and inter-menstrual bleeding more common
  • Pattern and duration of dysmenorrhea pain:

    • Onset just prior to or coincident with onset of menses; pain lasting 2-3 days with each or most menses vs Vary according to cause; change in pain pattern or intensity may indicate secondary disease
  • Pain at other times of menstrual cycle:

    • No vs Yes; may occur before, during, or after menses
  • Response to NSAIDs and/or OCs:

    • Yes vs Depends on the cause; generally, response to OTC NSAIDs is often inadequate or absent
  • Other possible associated symptoms:

    • Fatigue, HA, nausea, dizziness, backache, irritability, depression, and changes in appetite may occur at the same time as dysmenorrhea pain vs Vary according to cause of secondary dysmenorrhea; may include dyspareunia, pelvic tenderness
  • If patient is old, takes contraceptive but stop it, then it's SD

  • Myes of is at 25 bi contraceptives could ve masked symptons

    • Patient is 25
      • Do NOT refer immediately

    Plan

  • Canadian study of women treating PD

    • 77% nonRx analgesics
    • 14% Rx analgesics
    • 14% used oral contraceptives
    • 14% NHPs
    • 40% heat
    • 14% did nothing
  • Many women self-treat their menstrual pain using non-prescription agents, they frequently undertreat, which can negatively impact their quality of life

    Goals of Therapy

  • Symptom resolution or improvement

  • Minimize the disruption of usual activities

  • Suppress disease progression

  • Identify patients who may have underlying issues requiring further medical evaluation

    Pharmacotherapy Plan

  • 1st line options: NSAIDs and hormonal contraceptives

  • Treatment choice influenced by:

    • Hormonal contraception desire
    • Previous medication experience(s)
    • Contraindications to medication use
    • Risk-to-benefit ratio
    • Other patient preferences (e.g., cost)
  • For most women, drug therapy is required, and non-pharmacologic measures are used adjunctively

    • Pharmacists can only Edfornsaid-G- prescribe for NSAID

    Treatment Algorithm

  • Is contraception desired?

  • Is NSAID contraindicated?

  • Is NSAID therapy warranted and desired?

  • 3-7 is rating

  • 37 is rating severe

    Nonpharmacologic Adjunctive Therapy

  • Exercise

  • Tobacco cessation

  • Topical heat therapy

    • Vasodilation
  • Transcutaneous electrical nerve stimulation (TENS)

  • Stress

  • 150mins/week ->not full cessutiv can help too increase blood flow

  • Heat works quickly ->becoming bigger not a lot of evidence

  • .be

    Clinical Pearls

  • A pelvic examination is not necessary prior to initiating therapy.

  • Regular exercise is likely to improve dysmenorrhea symptoms.

  • Always recommend local heat as adjunctive dysmenorrhea therapy.

    Prescription Pharmacologic Therapy: NSAIDs (Not Approved)

    • Celecoxib
      *Not Health Canada approved but studies supports it

    Disclaimer for NSAIDs

    *Avoid in patients with renal failure, peptic ulcer disease,
    congestive heart-failure, and ASA-sensitive asthma (exception:
    celecoxib).
    *Use cautiously in patients with pre-existing CVD, cerebrovascular
    disease, or those with risk factors for cardiovascular disease (e.g.,
    hypertension, hyperlipidemia, diabetes mellitus and smoking).

    Prescription Pharmacologic Therapy: Other

    *Drug Class and Agent(s)
    *Combined hormonal contraceptives (CHCs) Combined oral contraceptive (COC) pills or the vaginal ring are ideal first-line options for women wishing for contraception Continuous or extended-cycle regimens decrease menstrual period frequency and may result in a more rapid onset of pain reduction, thus are generally preferable to cyclic regimens. The patch is also useful but may not be as effective at relieving dysmenorrhea as COC
    *Progestin-only medications
    *Levonorgestrel intrauterine device (IUD)
    *Etonogestrel implantable rod Approved in Canada in 2020 but not indicated for dysmenorrhea (used off-label)
    *Depot medroxyprogesterone is a treatment option for women who cannot tolerate estrogen and in those >35 y/o. It may also be used for SD treatment. To promote overall bone health, encourage adequate calcium (total of 1200 mg elemental calcium from all sources) and vitamin D supplementation (1000 IU daily) in women on DMPA therapy

    Clinical Pearls

*NSAIDs administered with regular dosing regimens should be considered first-line treatment for most women.
*All currently available NSAIDs are of comparable efficacy and safety.
*Select hormonal contraceptives should be offered to women who are not currently planning pregnancy.

*Pharmacotherapeutic Comparison

It is unknown whether NSAIDs or COCs are superior to one another in treating dysmenorrhea The combination may be beneficial but will fail ~10-20% of patients

  • Ask about previously tried therapies

  • Patients may perfer to:

    • use an NSAID they are familiar with
    • try another agent if adverse effects were experienced previously
