Treatment Options for Vaginal Discharge During Puberty
Normal vaginal discharge during puberty is physiological and typically requires no treatment, while pathological discharge should be treated based on the specific underlying cause, with the most common infections being bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis. 1
Normal Physiological Discharge
- Puberty brings hormonal changes that naturally increase vaginal secretions, creating a clear or whitish discharge that helps maintain vaginal health by keeping the vagina clean and preventing infections 1
- The vagina is a self-cleaning organ that maintains a natural balance of microorganisms, mainly hydrogen peroxide-producing lactobacilli that keep an acidic pH (≤4.5) 1
- External cleaning with water and mild soap is recommended, while douching should be avoided as it disrupts normal vaginal flora and increases risk of bacterial vaginosis 1
Diagnostic Approach for Abnormal Discharge
- Abnormal discharge may be characterized by changes in color, odor, consistency, or associated symptoms like itching, burning, or irritation 1, 2
- Diagnostic evaluation includes:
- Vaginal pH measurement (>4.5 suggests bacterial vaginosis or trichomoniasis) 3
- Microscopic examination with saline solution to identify trichomonads or clue cells 3
- Microscopic examination with 10% KOH to identify yeast or pseudohyphae of Candida 3
- Culture for Trichomonas vaginalis or Candida species when microscopy is inconclusive 3
Treatment Options by Specific Cause
1. Bacterial Vaginosis (BV)
- Symptoms: Homogeneous, white, non-inflammatory discharge with fishy odor 3
- Diagnosis: Requires three of the following: characteristic discharge, clue cells on microscopy, pH >4.5, and fishy odor with KOH 3
- Treatment:
2. Vulvovaginal Candidiasis
- Symptoms: Itching, vulvar irritation, white thick discharge resembling cottage cheese, vaginal pain, and dyspareunia 1, 3
- Diagnosis: Based on symptoms plus identification of yeast/pseudohyphae in KOH preparation or positive culture 1
- Treatment options:
- Topical azole formulations: clotrimazole, miconazole, terconazole, butoconazole, or tioconazole 1
- Oral fluconazole 150 mg in a single dose for those who prefer oral medication 4
- Clinical trials show comparable efficacy between oral fluconazole and intravaginal products, with therapeutic cure rates of approximately 55% 4
3. Trichomoniasis
- Symptoms: Yellow-green vaginal discharge, bad odor, irritation, and dysuria 1
- Diagnosis: Identification of motile trichomonads in wet mount or culture 1
- Treatment:
Special Considerations for Adolescents
- Approximately 10-20% of females have Candida in the vagina without symptoms and do not require treatment 1
- Self-medication is only recommended for those previously diagnosed with candidiasis who experience the same symptoms 1
- If symptoms persist after treatment or recur within 2 months, medical attention should be sought 1
- Recurrent vaginal discharge in young girls may require specialized pediatric gynecological evaluation 5
Common Pitfalls to Avoid
- Using vaginal douches disrupts the natural balance of vaginal flora and increases infection risk 1
- Treating asymptomatic Candida colonization is unnecessary and may lead to resistance 1
- Failure to consider non-infectious causes of discharge such as foreign bodies, labial adhesions, or chemical irritants in younger girls 5
- Overlooking the possibility of sexual abuse as a cause of vaginal discharge, especially with sexually transmitted infections in prepubertal girls 5
Hygiene Recommendations
- Clean only the external genitalia (vulva) with water and mild, unscented soap 1
- Avoid tight-fitting clothing and non-cotton underwear that can trap moisture 1
- Wipe from front to back after using the toilet to prevent introducing bacteria from the rectum to the vagina 1
- Change out of wet clothing promptly, including swimwear 1
