There are several possible causes of an itchy and swollen vagina, including:

• Lack of moisture: When the vagina isnt lubricated enough, it can become itchy and swollen.

• Yeast infections: These are caused by an overgrowth of candida albicans, which is a naturally occurring yeast found in small quantities in the vagina. A change in the pH balance of the body may make this yeast grow out of control, causing an infection that leads to an itchy and swollen vagina.

• Bacterial vaginosis (BV): This happens due to a disturbance in the vaginas normal pH levels that makes it itchy and swollen. Normally, there are Lactobacillus bacteria living in the vagina that produce hydrogen peroxide as a byproduct of digesting sugars they metabolize from glycogen.

• Contact dermatitis: This is an allergic reaction that may cause the vagina to swell. The vagina is a sensitive part of the body and may react to any number of ingredients found in personal care products such as soaps, lubricants, vaginal washes and douches, tampons, and vaginal contraceptives.

• Sexually transmitted infections (STIs): These can cause vaginal swelling, including genital herpes and trichomoniasis.

• Skin conditions: Eczema and lichen planus are examples of skin conditions that can cause vaginal itching and swelling.

• Irritation: Irritation from things that directly affect the vagina, such as scented products, douching, and steaming, can lead to itching, irritation, and swelling.

If you are experiencing an itchy and swollen vagina, it is important to see a doctor for a proper diagnosis and treatment plan. Some treatments may include antihistamines, hydrocortisone cream, antibiotics or antiviral medication, and prescription topical medication.
