Why is my genitals red, swollen and itchy?

Vulvar itching and redness and swelling are very common diseases in women. This can also be a symptom of gynecological inflammation. When an attack occurs, some patients will experience unbearable itching, as well as redness, swelling and stinging, which will affect the patient's life, work, study and sleep quality. What causes itching and redness in the vagina? The following are the main reasons caused by it.

1. Vaginal trichomoniasis: Itching of the vulva and vagina, foamy leucorrhea, often accompanied by a special odor, and eczematous changes in the vulva after scratching. A vaginal smear test can be used to distinguish it from the above conditions.

2. Fungal vaginitis: itching of the vulva and vagina, flushing of the vulva, dregs-like leucorrhea with an odor. Scratching may cause eczematous changes of the vulva dermatitis.

3. Pinworm infection: It mainly affects young girls, but adult women can also be infected. When the anus relaxes at night, the pinworms crawl out of the rectum and swim to the vulva to mate and lay eggs, and stimulate the skin and mucous membranes of the vulva, causing local itching.

4. Pubic lice: Pubic lice often stick to the skin surface or attach to the roots of pubic hair. Pubic lice eggs are grayish white and the size of a needle. The bites of pubic lice and their venom and excrement can cause itching and desquamation of the skin, and may lead to eczematous changes and folliculitis.

5. Local skin uncleanness: Some women use toilet paper improperly, and the skin of the vulva is soaked by menstrual blood, vaginal secretions, and even urine, feces and sweat, which causes chronic inflammation of the local skin and causes vulva itching.

6. Scabies infection: When scabies occurs, the external skin lesions are the most serious, so local itching is also the most obvious.

7. Skin diseases of the vulva: The skin lesions of tinea cruris often extend to the vulva, causing severe local itching.

The above reasons can all cause itching and redness and swelling of the vagina. In addition to pathological reasons, it is also related to women’s living habits. Therefore, it is recommended that women, in addition to paying attention to personal hygiene, try to wear comfortable and breathable pants, avoid wearing tight and uncomfortable pants, reduce friction on the vulva, etc.
