Causes of vaginal itching

The reason why you may be experiencing vaginal itching can be affected by factors like your age. Below are some common reasons that women find themselves experiencing vaginal itching.  

Bacterial vaginosis

Bacterial vaginosis (BV) is a form of vaginitis caused by an overproduction of harmful bacteria. It occurs at the same time as a decrease in the bacteria responsible for maintaining a healthy balance in the vaginal environment. 

The condition typically occurs in women between the ages of 15 to 44. African American women are twice as likely to end up with BV than Caucasian women. Other factors that can put you at risk for developing BV include:

While BV can be passed through sexual activity, the condition can also occur in women who are not sexually active. Vaginal itching can be one of the symptoms that women with BV experience. 

Contact dermatitis

Contact dermatitis is a condition where the skin becomes irritated because of exposure to specific compounds or products. You may find yourself experiencing vaginal itching if you continually expose your vagina to the following items:

  • Laundry detergents
  • Certain body soaps
  • Douches and other feminine products

Sexually transmitted disease

Sexually transmitted diseases (STDs) typically pass from person to person via sexual contact. It’s also possible to contract an STD through kissing or other kinds of body contact. Sexually transmitted diseases that can have symptoms that include vaginal itching include:

Genital wartsGenital warts are caused by contracting human papillomavirus (HPV). It can lead to symptoms like skin warts along with itching around the vagina. People can also contract HPV through oral sex.

Herpes Herpes is a viral infection that can lead to sores and blisters in the genital area. It can also spread to other body parts like the eyes and brain. Recurrent vaginal itching can be a sign of a herpes infection. A doctor may be able to prescribe medication that can alleviate your symptoms.

Gonorrhea — Gonorrhea is a bacterial infection that can lead to serious damage to a woman’s reproductive organs. It’s caused by the Neisseria gonorrhoeae bacteria and is typically passed through some form of sexual interaction. You can also contract gonorrhea by contacting bodily fluids containing the bacteria. 

Chlamydia — Chlamydia can be passed from person to person through sexual contact. While the condition usually does not cause visible symptoms, women can experience vaginal itching because of a chlamydia infection. 

Pubic Lice — Pubic lice, often referred to as crabs, can get into the hairs of the genital area. The organisms can also be passed by using objects infested with public lice like clothing, bedding, or towels. Pubic lice can spread to other areas of the body, like your eyelashes. Along with vaginal itching, you might also notice the appearance of bite marks in that area.

Diagnosis and tests for vaginal itching

Doctors typically start by asking questions about your vaginal itching and any accompanying symptoms. They will likely also want information about your past medical history, including any past or current STDs. From there, they usually conduct a physical exam of your vagina and genital area. 

If there is discharge present, the doctor may decide to take a sample and examine it for signs of various microorganisms. They usually send that sample for laboratory testing to look for signs of a possible STD. 

Treatments for vaginal itching

Your doctor may recommend that you use certain prescription or over-the-counter (OTC) medications to relieve the symptoms. Some lifestyle changes they may suggest to alleviate your vaginal itching can include:

  • Showering once per day
  • Changing your underwear more frequently
  • Using an unscented body powder with cornstarch to help keep the vaginal area dry
  • Avoiding talc-based body powders
  • Washing with a nonallergenic soap or only warm water
  • Not using creams, douches, or feminine hygiene sprays
