What causes premenstrual vulvar itching?

Many women will feel vulvar itching before menstruation. Vulvar itching not only affects daily life and work, but also causes conflicts and discord between couples. Patients are restless and irritable, which leads to work and life being disrupted. If it is more serious, it will cause other diseases. What is the cause of vulvar itching before menstruation? Let us take a look at it together.

Causes of vulvar itching before menstruation:

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

2. 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. Do not clean blindly by yourself.

3. 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.

4. 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.

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

6. 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.

There are many reasons for premenstrual vulvar itching. No matter which one it is, it is best to seek medical treatment as soon as possible to avoid delaying the condition from getting worse, or even leading to new gynecological diseases. We should also pay attention to some hygienic habits in caring for the genitals. It is best to choose cotton products such as underwear, sanitary napkins, etc. that come into direct contact with printed cloth.
