1. Introduction
- Definition: Vaginal dryness is a common condition where the vaginal tissues lack adequate lubrication and moisture, often leading to discomfort, itching, or pain during intercourse (dyspareunia).
- Epidemiology: Affects up to 50% of postmenopausal women but can occur at any age due to various factors, including hormonal changes and lifestyle factors.
- Significance: While often benign, untreated vaginal dryness can affect quality of life, sexual health, and intimate relationships.
2. Causes and Risk Factors
- Causes:
- Hormonal:
- Oestrogen deficiency (e.g., menopause, postpartum period, breastfeeding).
- Hormonal contraceptives with low oestrogen levels.
- Lifestyle and Environmental:
- Smoking, alcohol use, or dehydration.
- Excessive douching or use of scented feminine hygiene products.
- Medical:
- Autoimmune disorders (e.g., Sjögren’s syndrome).
- Cancer treatments (e.g., chemotherapy, radiotherapy).
- Certain medications (e.g., antihistamines, antidepressants).
- Hormonal:
- Risk Factors:
- Ageing and menopause.
- Recent childbirth or breastfeeding.
- Smoking or chronic dehydration.
- Psychological stress or lack of arousal during intercourse.
3. Pathophysiology
- Vaginal lubrication is maintained by oestrogen-dependent processes that keep the vaginal epithelium healthy and hydrated. Oestrogen deficiency leads to thinning of the epithelium, reduced blood flow, and decreased secretion from the vaginal glands, resulting in dryness and atrophy.
4. Symptoms and Features
- Common Symptoms:
- Vaginal itching, burning, or discomfort.
- Pain during intercourse (dyspareunia).
- Light bleeding or spotting after intercourse.
- Associated Symptoms:
- Urinary symptoms, such as increased frequency or urgency.
- Recurrent urinary tract infections (UTIs).
5. Complications
- Sexual dysfunction due to pain or discomfort.
- Increased risk of vaginal or urinary tract infections due to disruption of the natural vaginal microbiota.
- Impaired intimate relationships and psychological distress.
6. Diagnosis
- Clinical History: Assess for symptoms, hormonal status, and contributing lifestyle or medical factors.
- Physical Examination:
- Vaginal atrophy (thinning of vaginal walls, loss of elasticity).
- Redness, inflammation, or dryness of the vaginal mucosa.
- Laboratory Tests:
- Vaginal pH (elevated in oestrogen deficiency).
- Hormonal tests if needed (e.g., oestrogen, FSH levels in menopausal women).
7. Management Overview
- Goals: Relieve symptoms, restore vaginal moisture, and address underlying causes.
- Approach: Non-hormonal treatments, hormonal therapies (if appropriate), and lifestyle changes.
8. Treatment Options with Cost (USD)
- Non-Hormonal Therapies:
- Vaginal moisturisers (e.g., Replens): ~$10–$30 per pack.
- Lubricants (e.g., water-based, silicone-based): ~$5–$15 per bottle.
- Hormonal Therapies:
- Vaginal oestrogen creams (e.g., estradiol): ~$20–$50 per tube.
- Vaginal oestrogen tablets or rings: ~$30–$70 per treatment cycle.
9. Advanced Treatment Options with Cost (USD)
- Laser Vaginal Rejuvenation:
- Cost: ~$2,000–$3,500 for a series of treatments.
- Ospemifene:
- Oral selective oestrogen receptor modulator (SERM) for dyspareunia: ~$200–$300 per month.
10. Pharmacological Treatment
- First-line: Vaginal moisturisers and lubricants for symptomatic relief.
- Second-line: Vaginal oestrogen therapy for persistent symptoms or those with confirmed hormonal deficiency.
- Refractory Cases: Ospemifene or laser therapy for women unresponsive to standard treatments.

12. Lifestyle Interventions
- Avoid irritants such as scented soaps, douches, or tight clothing.
- Increase hydration and maintain a healthy diet.
- Use lubricants during sexual activity to prevent discomfort.
- Engage in regular sexual activity or vaginal dilation to promote blood flow and maintain elasticity.
13. Monitoring Parameters
- Symptom improvement, such as reduced discomfort and improved lubrication.
- Vaginal pH normalisation (if monitored).
- Monitor for side effects of hormonal therapies, especially in postmenopausal women with a history of breast cancer or thromboembolic events.
14. Patient Counseling Points
- Educate on the difference between moisturisers (daily use) and lubricants (for sexual activity).
- Explain that vaginal oestrogen therapy is generally safe and effective, with minimal systemic absorption.
- Discuss the importance of maintaining vaginal health through hydration and avoiding irritants.
- Encourage open communication with healthcare providers regarding symptoms and concerns.
15. Special Populations
- In Postmenopausal Women: Oestrogen deficiency is the most common cause; local oestrogen therapy is typically the first-line treatment.
- In Breast Cancer Survivors: Non-hormonal options, such as moisturisers or lubricants, are preferred.
- In Younger Women: Address hormonal imbalances, psychological factors, or medication-related causes.
16. Prevention
- Avoid overuse of feminine hygiene products or douches.
- Maintain adequate hydration and a balanced diet.
- Manage chronic conditions like diabetes, which can exacerbate dryness.
