Is vulvar itching hereditary?

Vulvar pruritus is a common gynecological disease. In fact, the occurrence of vulvar pruritus is closely related to the hygiene of the patient's private parts. We must pay attention to the causes of vulvar pruritus. Many patients are concerned about whether vulvar pruritus is hereditary. In fact, vulvar pruritus does not have any genetic factors. Let's take a look at the causes of vulvar pruritus.

What are the causes of vulvar itching?

1. Fungal vaginitis causes itching of the vulva and vagina, flushing of the vulva, and dregs-like leucorrhea with an odor. Scratching can cause eczematous changes of the vulvar dermatitis.

2. Trichomoniasis. Itching of the vulva and vagina, foamy leucorrhea, often accompanied by a special odor, and eczematous changes of the vulva after scratching. A smear examination of vaginal secretions can distinguish it from the above diseases. Do not clean it blindly.

3. Pubic lice. Pubic lice often lie on the surface of the skin or on the roots of pubic hair. Pubic lice eggs are grayish white and the size of a pinhead. Pubic lice bites and their venom and excrement can cause itching and scaling of the skin, and can cause eczema-like changes and folliculitis.

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

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

6. Local skin is unclean. 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.

7. Drug allergy. Women with allergic constitutions may experience "fixed drug eruptions" caused by taking sulfonamides or other drugs. These eruptions often occur at the junction of the skin and mucous membranes of the vulva. In addition to local itching, erosion and exudation may also occur. Vulvar itching may also occur if allergic reactions and contact dermatitis occur when using drugs for vaginal washing or vaginal insertion.

8. Vulvar skin diseases. Tinea cruris often causes skin damage to the vulva, causing severe local itching. Vulvar eczema and neurodermatitis cause more severe local itching. The former is manifested as papules and blisters with unclear local skin boundaries and erosion exudate, while the latter often causes skin thickening and lichenification due to scratching. In addition to causing local itching, vulvar leukoplakia is often accompanied by vulvar malnutrition and skin atrophy.

9. Viral infection. Genital warts mostly occur on the vaginal wall, cervical opening and vulva of women, and may also cause foul-smelling vaginal discharge. Molluscum contagiosum occurring on the vulva often manifests as round papules with an umbilical depression in the center, which may also cause vulvar itching. Genital herpes often manifests as rice-sized, bright blisters on the urethral opening and vaginal wall, accompanied by local itching.

10. Sexual intercourse allergy. This is an allergic reaction that occurs during sexual intercourse. There are allergies to semen, condoms, and friction.

Warm reminder: The emergence of sexual intercourse allergy is a problem that we should pay attention to. In fact, when such symptoms appear, we must be cautious when treating them, and try not to let such diseases cause more serious complications!
