Why is my vulva so itchy at night?

Nighttime itching of the vulva may be related to fungal infection, allergic reactions, changes in hormone levels and other factors. It is recommended to seek medical treatment promptly to determine the cause of the disease and follow the doctor's instructions for treatment.

Fungal infection is one of the common causes of nighttime itching of the vulva. Candida albicans infection can cause redness, swelling and burning of the vulva, accompanied by a bean-like discharge. Antifungal drugs such as clotrimazole vaginal tablets, miconazole nitrate suppositories, or fluconazole capsules can be used as directed by your doctor. Keeping the vulva clean and dry and avoiding tight-fitting synthetic underwear can help relieve symptoms.

Allergic reactions may also cause itching to intensify at night, and skin erythema and papules may appear after contact with allergens such as sanitary napkins and detergents. You can use antihistamines such as loratadine tablets and cetirizine tablets as directed by your doctor, and apply hydrocortisone cream topically. It is recommended to change to hypoallergenic sanitary products and avoid scratching the skin.

Fluctuating hormone levels can affect skin barrier function, and the drop in estrogen in menopausal women can easily lead to vulvar dryness and itching. You can use estriol cream topically to supplement estrogen as directed by your doctor, and use vitamin E ointment to moisturize the skin. Wash with warm water and avoid using alkaline soap.

Parasitic infections such as pubic lice can also cause severe itching at night, and gray-white eggs can be seen attached to the pubic hair. Pubic hair needs to be shaved and permethrine lotion or malathion cream should be used as directed by your doctor. Close-fitting clothing should be scalded and washed with boiling water, and sexual partners should be treated at the same time.

When diabetic patients have poor blood sugar control, urine sugar can irritate the vulva skin and easily cause itching. It is necessary to monitor blood sugar and use hypoglycemic drugs such as insulin or metformin as directed by your doctor. Keeping your vulva clean and wearing breathable cotton underwear can help reduce discomfort.

Pay attention to vulvar hygiene in daily life, choose loose and breathable cotton underwear, and avoid using irritating lotions. Reduce the intake of spicy food and maintain a regular schedule. If the itching persists or is accompanied by abnormal discharge, you should go to a gynecologist for examination in time.
