WOMEN’S HEALTH: POLYCYSTIC OVARY SYNDROME, DYSMENORRHOEA, AND PREMENSTRUAL SYNDROME: A TEACHER’S COMPREHENSIVE GUIDE
Welcome, future pharmacists and healthcare professionals!
Women’s health disorders include a broad spectrum of illnesses that specifically affect the reproductive system of women as well as other illnesses that may affect women more than males. The etiology, symptoms, severity, and treatment approaches of these illnesses might differ greatly from one another. As a pharmacy educator with years of experience teaching pharmacotherapeutics, I have observed that students often find women’s health disorders challenging due to the complexity of the reproductive system and hormonal interactions. Let me tell you: Understanding women’s health disorders is essential for every pharmacy professional.
In this comprehensive guide, I will walk you through the major women’s health disorders—Polycystic Ovary Syndrome (PCOS), Dysmenorrhoea, and Premenstrual Syndrome (PMS). I will explain their types, etiology, pathogenesis, clinical manifestations, and both non-pharmacological and pharmacological management. By the end of this article, you will have a thorough understanding of these critical conditions. Let us begin our journey!
Dpharmguru’s exam insights:
Women’s health disorders are frequently tested in pharmacy exams. Remember: PCOS is a hormonal imbalance causing irregular periods and excess androgens. Dysmenorrhoea is painful menstruation. PMS is a group of symptoms occurring before menstruation. Pay special attention to the pharmacological management of each condition—these are almost always asked in exams! Also, remember the difference between primary and secondary dysmenorrhoea.
1. POLYCYSTIC OVARY SYNDROME (PCOS)
Polycystic Ovary Syndrome (PCOS) is a condition of hormonal imbalance when ovaries (that produce and release eggs) produce excessive male hormones (androgens). In PCOS, the ovaries produce abnormally high levels of androgens and cause imbalance in reproductive hormones. Thus, PCOS patients experience irregular menstrual cycles, missed periods, and erratic ovulation. Anovulation (lack of ovulation) may lead to the development of small cysts on the ovaries.
Etiology of PCOS
- Higher Levels of Androgens: Due to high levels of androgens, ovulation does not occur, resulting in irregular menstrual cycles. Erratic ovulation can lead to development of small, fluid-filled sacs (cysts) on the ovaries. High androgen levels cause acne and excessive hair growth.
- Insulin Resistance: Due to high levels of insulin, the ovaries make and release androgens, which further suppress ovulation and result in other PCOS symptoms.
- Low-grade Inflammation: PCOS patients have chronic low-grade inflammation which can be detected by blood tests measuring levels of C-reactive protein (CRP) and WBCs.
- Genetics: Hereditary factors play a role in PCOS development.
Pathogenesis of PCOS
The exact pathogenesis of PCOS is not known. However, the following mechanisms are believed to have a role:
- Hormonal imbalance (excess androgens)
- Insulin resistance
- Genetic inheritance
- Chronic low-grade inflammation
Clinical Manifestations of PCOS
- Irregular periods: Abnormal menstrual cycle leading to missing periods, no periods, or heavy bleeding during periods
- Abnormal hair growth (hirsutism): Excessive and heavy hair growth on face, arms, chest, and abdomen
- Acne: On back, chest, and face
- Obesity: Overweight or obese, difficulty losing weight
- Cysts: Small pockets of fluid on the ovaries
- Skin tags: Little flaps of extra skin in the armpits or on the neck
- Infertility: Due to decreased frequency or lack of ovulation
Non-Pharmacological Management of PCOS
Losing 5-10% of body weight helps in:
- Regulating the menstrual cycle
- Improving PCOS symptoms
- Improving cholesterol levels
- Lowering insulin levels
- Reducing risk of heart disease and diabetes
Lifestyle Modifications:
- Diet: Low Glycemic Index (low GI) diet includes carbohydrate-rich fruits, vegetables, and whole grains
- Exercise: 30 minutes of moderate-intensity exercise 3 days a week
- Acupuncture: May improve PCOS symptoms
Pharmacological Management of PCOS
- Hormonal Birth Control: Birth control pills, patches, shots, vaginal ring, or IUD—regulate menstrual cycle, improve acne, and help with excess hair growth
- Insulin-sensitizing Medicine: Metformin—helps the body process insulin, controls insulin levels, and improves menstrual cycle
- Medications to Block Androgens: Control acne or excessive hair growth
- Lifestyle Changes: Losing weight and maintaining a healthy diet
Dpharmguru’s exam insights:
PCOS management is frequently tested. Remember: Metformin is used to improve insulin sensitivity. Hormonal contraceptives regulate menstrual cycles and reduce androgen effects. Weight loss of 5-10% significantly improves symptoms. A common exam question is: “What is the first-line treatment for PCOS?” (Answer: Lifestyle modifications including weight loss, followed by hormonal contraceptives or Metformin).
2. DYSMENORRHOEA
Dysmenorrhoea is a condition of painful menstrual bleeding. In other words, it is a condition of painful menstruation having a magnitude that makes performing day-to-day activities difficult for the woman.
A. Primary Dysmenorrhoea (Spasmodic)
A condition of recurring menstrual cramps is known as primary dysmenorrhoea. This pain may be mild or severe and generally occurs in the lower abdomen, back, or thighs, 1–2 days prior to regular menstrual bleeding.
Etiology of Primary Dysmenorrhoea
- Menstrual flow through the cervix
- Increased concentration of prostaglandin F2-alpha in menstrual fluid
- Cervical stenosis
- Uterus malposition
- Lack of exercise
- Menstrual anxiety
Pathogenesis of Primary Dysmenorrhoea
When the released egg is not fertilised, the corpus luteum degenerates, and oestrogen and progesterone production is reduced. Endometrial cells are sensitive to this reduction in progesterone levels and subsequently release prostaglandins.
Prostaglandins act in the following two ways in the uterus:
- Spiral artery vasospasm leading to ischaemic necrosis and shedding of the superficial layer of endometrium
- Increased myometrial contractions
Primary dysmenorrhoea occurs when prostaglandins (PGF₂α and PGE₂) are released in excessive amounts by endometrial cells.
Clinical Manifestations of Primary Dysmenorrhoea
- Pain a few hours prior to the onset of menstruation or along with it
- Menstrual pain remains severe for a few hours or up to 24 hours
- Spasmodic pain limited to the lower abdomen or extending to the back and medial aspect of thighs
- Nausea, vomiting, fatigue, diarrhoea, headache, and tachycardia
- Vasomotor changes producing pallor, cold sweats, and occasional fainting
- Syncope and collapse in severe cases
Non-Pharmacological Management of Primary Dysmenorrhoea
- Heat therapy: Applying heat to the lower abdomen reduces pain
- Physical activity: Light exercise or stretching increases blood flow
- Relaxation methods: Meditation or deep breathing relieves tension and stress
- Dietary modifications: Foods high in anti-inflammatory compounds
- Herbal remedies: Cinnamon or ginger may help relieve discomfort
- Acupuncture: Traditional acupuncture may reduce pain
- Lifestyle changes: Relieving stress, staying hydrated, quitting smoking and alcohol
Pharmacological Management of Primary Dysmenorrhoea
- Analgesics and antispasmodics (except pethidine or morphine due to addiction risk)
- Prostaglandin synthetase inhibitors
- Oral contraceptives (combination of oestrogen and progestogen)
Commonly Used NSAIDs
| Group | Drugs and Dosage |
|---|---|
| Fenamate Group | Mefenamic acid 150–500 mg at 8 hours interval OR Flufenamic acid 100–200 mg at 8 hours interval |
| Propionic Acid Derivatives | Ibuprofen 400 mg at 8 hours interval OR Naproxen 250 mg at 6 hours interval |
| Indomethacin | 25 mg at 8 hours interval |
B. Secondary Dysmenorrhoea (Congestive)
A condition of pain associated with menstruation, arising in the presence of pelvic pathology, is known as secondary dysmenorrhoea.
Etiology of Secondary Dysmenorrhoea
- Cervical stenosis
- Chronic pelvic infection
- Pelvic endometriosis
- Pelvic adhesions
- Adenomyosis
- Uterine fibroid
- Endometrial polyp
- IUCD
- Uterine and pelvic congestion
- Obstructed Müllerian duct anomalies
Clinical Manifestations of Secondary Dysmenorrhoea
- Lighter menstrual pain in the back and pelvic area appears 3–5 days before the menstrual period and reduces with the onset of bleeding
- Uneasiness occurs between periods
- Symptoms of associated pelvic pathology are present
Pharmacological Management of Secondary Dysmenorrhoea
- NSAIDs: Aspirin, Naproxen, Ibuprofen—decrease prostaglandin synthesis and inflammation
- Hormonal therapies: Hormonal IUDs, birth control tablets, and patches—control menstruation and decrease pain
- Prostaglandin inhibitors: Mefenamic acid—target production of prostaglandins
- Antidepressants: SSRIs and TCAs—control chronic pain and elevate mood
- Muscle relaxants: Baclofen, Cyclobenzaprine—relieve tension in pelvic muscles
- Antispasmodic agents: Dicyclomine, Hyoscine butylbromide—reduce cramps by relaxing smooth muscles
Dpharmguru’s exam insights:
Dysmenorrhoea is frequently tested. Remember: Primary dysmenorrhoea has no pelvic pathology; secondary dysmenorrhoea has underlying pelvic pathology. NSAIDs are first-line treatment for both. A common exam question is: “What is the difference between primary and secondary dysmenorrhoea?” (Answer: Primary has no pelvic pathology; secondary has underlying pelvic pathology).
3. PREMENSTRUAL SYNDROME (PMS)
Premenstrual Syndrome (PMS) refers to any unpleasant or uncomfortable symptom that arises during the menstrual cycle and may affect normal body functioning. These symptoms are either short (last for hours) or long-lasting (last for days).
Etiology of PMS
- Smoking
- Being under a lot of stress
- Inactivity
- Lack of sleep
- Excessive consumption of alcohol, salt, red meat, or sugar
- Depression
Pathogenesis of PMS
Early theories suggest abnormalities in ovarian sex steroid levels induce PMS; however, this is contradicted as no differences have been found between symptomatic and asymptomatic women.
Key Mechanisms:
- Sex steroids easily pass through the blood-brain barrier
- Progesterone undergoes metabolism in the brain, resulting in allopregnanolone and pregnanolone, which stimulate the GABA inhibitory neurotransmitter system
- High concentrations produce anxiolytic, sedative, and anaesthetic effects
- Low concentrations cause anxiety, negative mood, and aggression
- Oestrogen and progesterone affect serotonergic activity in the brain
- Progesterone increases MAO, reducing 5-HT availability and causing depression
- Oestrogen increases MAO degradation, increasing tryptophan and enhancing serotonin transport
Clinical Manifestations of PMS
- Psychological symptoms (depression, anxiety, and irritability)
- Gastrointestinal symptoms (bloating)
- Fluid retention (swollen fingers, ankles, and feet)
- Skin problems (acne)
- Headache
- Vertigo
- Fainting
- Muscle spasms
- Heart palpitations
- Allergies
- Vision problems
- Eye infections
- Diminished libido (sex drive)
Non-Pharmacological Management of PMS
- Assurance, yoga, stress management, and dietary changes
- Avoid consumption of salt, caffeine, and alcohol in the luteal phase
- Non-hormonal treatment:
- Tranquillisers or antidepressants (SSRIs and NRIs) if required
- Pyridoxine 100 mg BID—helps correct tryptophan metabolism
- Furosemide 20 mg QD for 5 days or a week—reduces fluid retention
- Alprazolam 0.25 mg BID—for persistent anxiety
Pharmacological Management of PMS
1. Hormonal Treatment
- Oral Contraceptive Pills (OCPs): Given for 3–6 cycles to suppress ovulation. Newer OCPs with drospirenone have anti-mineralocorticoid and anti-androgenic properties.
- Progesterone: Levonorgestrel intrauterine system suppresses the ovarian cycle.
- Spironolactone: 25–200 mg QD in the luteal phase—controls symptoms with anti-mineralocorticoid and anti-androgenic properties.
- Bromocriptine: 2.5 mg QD or BID—relieves breast complaints.
2. Suppression of Ovarian Cycle
- Danazol: 200 mg QD—causes amenorrhoea
- GnRH Analogues: Used for 6 months to suppress gonadal steroids
- Goserelin (Zoladex): 3.6 mg SC at 4 weeks interval
- Leuprorelin acetate (Prostap): 3.75 mg SC or IM at 4 weeks interval
- Triptorelin (Decapeptyl): 3 mg IM at 4 weeks interval
Dpharmguru’s exam insights:
PMS management is frequently tested. Remember: SSRIs are first-line for severe PMS. OCPs suppress ovulation and improve symptoms. Spironolactone helps with fluid retention and androgen-related symptoms. A common exam question is: “What is the first-line treatment for severe PMS?” (Answer: SSRIs or hormonal contraceptives).
