What causes itching of the female external genitalia

Patient's question:

During this period, sexual activity might be more frequent, and personal hygiene quality has improved. However, I've been experiencing persistent vulvar itching, which is very painful. I bought some medication to wash with, but it's not very effective. I've been changing my underwear once a day, but the symptoms haven't stabilized yet.

Doctor's answer:

There are several reasons that can cause vulvar itching. Individuals suffering from this condition should identify the cause and seek appropriate treatment.
1. Avoid using indiscriminate or harmful medications, scratching, and local friction. Refrain from alcohol and spicy foods, as well as seafood and other allergenic medications.
2. Pay attention to menstrual hygiene. Change sanitary pads frequently during the menstrual cycle and clean the area regularly. Maintain vulvar cleanliness and dryness. Avoid hot water bathing or washing with soap.
3. If there is rust or infection locally, a 1:5000 potassium permanganate solution can be used for soaking.
4. Do not wear tight or skin-tight pants. Underwear should be loose, breathable, and preferably made of cotton.
5. During medical examination, check for the presence of mold or trichomoniasis. If detected, seek timely treatment rather than self-medication. For persistent cases, a blood sugar test should be conducted. Severe vulvar itching requires immediate medical attention.
