Why does using sanitary pads cause itching?

Generally, itching caused by using sanitary pads may be due to poor breathability, allergies, eczema, bacterial vaginosis, or vulvovaginal candidiasis. Treatment may involve lifestyle adjustments or medication. Specific analyses are as follows:

1. Poor Breathability

Pads with poor breathability can lead to inadequate ventilation in the local area when used for prolonged periods. Moisture in the genital area, combined with irritation from secretions, may cause localized itching. Regularly changing sanitary pads and maintaining good hygiene usually resolves the issue.

2. Allergy

Some individuals may be allergic to the materials used in sanitary pads. Contact with such materials may trigger itching, along with symptoms like local rashes and red patches. Under a doctor's guidance, medications such as calamine lotion or loratadine tablets may be used for treatment.

3. Eczema

Eczema is a type of skin inflammation that may affect the vulvar area, causing dryness, redness, swelling, and itching. Friction or irritation—such as from pad use—may worsen eczema symptoms. Topical medications like dani-phenol ointment or compound betamethasone and camphor cream may be applied as directed by a physician to relieve symptoms.

4. Bacterial Vaginosis

Bacterial vaginosis results from an imbalance of bacteria in the vagina and is typically accompanied by unpleasant odor, grayish-white or gray-green discharge, itching, and a burning sensation. Using sanitary pads may disrupt the vaginal pH balance, creating a favorable environment for bacterial growth. It is recommended to follow medical advice and use medications such as metronidazole suppositories or nifuratel tablets to manage the condition.

5. Vulvovaginal Candidiasis

Candida is a common fungus normally present in the microbial flora of the vagina and vulva. However, when microbial balance is disrupted or under certain conditions, Candida may overgrow, leading to vulvovaginal candidiasis. Pad use may increase moisture and friction, providing favorable conditions for Candida growth. Excessive Candida growth can cause itching, pain, burning, redness, swelling, and thick white, curd-like discharge in the vaginal and vulvar areas. Under medical guidance, treatments such as miconazole nitrate vaginal tablets or clotrimazole cream may be used.

It is advisable to change sanitary pads frequently and choose high-quality, reputable products. If itching is severe, it is recommended to seek medical evaluation to determine the underlying cause and receive appropriate treatment.
