What causes the vulva to be itchy?

Vulvar itching may be caused by vulvitis, vaginitis, contact dermatitis, diabetes, pubic lice, etc. Vulvar itching usually manifests as local skin redness, burning sensation, abnormal secretions and other symptoms. It is recommended to seek medical treatment in time to determine the cause.

1. Vulvitis

Vulvitis is an inflammation of the skin or mucous membrane of the vulva, which may be related to factors such as poor local hygiene and urine irritation. It is usually accompanied by symptoms such as vulvar redness, swelling, and pain. For treatment, you can use topical antibiotics such as erythromycin ointment and mupirocin ointment as directed by your doctor, or use proprietary Chinese medicines such as Compound Cortex Phellodendron Liquid Ointment. It is necessary to keep the vulva clean and dry on a daily basis and avoid scratching.

2. Vaginitis

Vaginitis includes fungal vaginitis, bacterial vaginosis and other types, which may be related to bacterial imbalance and reduced immunity, and are often accompanied by symptoms such as abnormal leucorrhea and odor. Treatment requires choosing clotrimazole vaginal tablets, metronidazole suppositories and other drugs according to the pathogen. It is recommended to wear cotton underwear and avoid using irritating vaginal washes.

3. Contact dermatitis

Contact dermatitis is usually caused by allergies or irritations, which may be related to contact with sanitary napkins, detergents, etc., and manifests as itching and rash. For treatment, you can use calamine lotion, hydrocortisone butyrate cream and other drugs as directed by your doctor. It is necessary to stop using suspected allergenic products immediately and avoid scalding the affected area with hot water.

4. Diabetes

Poor blood sugar control may lead to increased sugar content in the vulvar skin, which may lead to secondary infection or neuropathy causing itching. Patients may have symptoms such as polydipsia and polyuria. Blood sugar needs to be controlled through oral metformin tablets or insulin, together with local anti-infective treatment. Blood sugar needs to be monitored daily and diet controlled.

5. Pubic lice

Pubic pediculosis is caused by a parasitic infection that is spread through sexual contact or shared clothing and is characterized by severe itching and visible worms. Treatment requires shaving the pubic hair and using Lindane cream, benzyl benzoate liniment and other drugs as directed by the doctor. Close-fitting clothing needs to be boiled and disinfected, and sexual partners should be treated at the same time.

You should choose breathable cotton underwear and change it daily to avoid friction and irritation from wearing tight pants. Just use warm water when cleaning the vulva. There is no need to use lotion frequently. Reduce the intake of spicy food and control sugar. If the itching lasts for more than 3 days or symptoms such as ulcers and bleeding occur, you must seek medical attention immediately to investigate the serious cause. When itching is obvious at night, cold compress can be used to relieve it. Avoid scratching, which may cause skin damage and infection.
