What are the most common causes of vaginal rashes?

Vaginal rashes are often the result of allergic reactions, sexually transmitted diseases, and bacterial imbalances. Although they are often uncomfortable, they are rarely dangerous. Vaginal rashes are usually easy to treat when done so quickly. The most common causes of vaginal rashes are contact dermatitis, bacterial vaginosis, candidiasis, and trichomoniasis.

Contact dermatitis occurs when the flesh of the vaginal area comes into contact with an irritant. Perfumes, soap, and allergenic materials like latex commonly cause contact rashes. This type of vaginal rash subsides after the irritant is removed. Medical attention is rarely needed for contact dermatitis, but a doctor will usually examine the rash to rule out more serious conditions.

Bacterial vaginosis is a vaginal condition that can be caused by a variety of species of bacteria. It is characterized by an itchy rash that is usually accompanied by unpleasant discharge. Bacterial vaginosis is not a sexually transmitted condition and is not contagious. It occurs as a result of a bacterial imbalance. After a doctor performs a test to confirm the diagnosis, an antibiotic is prescribed to control the condition.

Thrush is a common fungal infection that can occur when the yeast population in the vagina becomes unbalanced. The classic features of this type of rash include burning, itching, and redness. If the yeast multiplies rapidly, it can cause a full-blown yeast infection, characterized by a discharge similar to cottage cheese. Thrush presents a type of rash that is similar to other conditions, so it is important to have a doctor examine the rash and confirm the diagnosis. A yeast infection is commonly treated with antifungal medications.

Trichomoniasis is a sexually transmitted infection caused by a parasite. Common symptoms include a rash in and around the vaginal area and vulva. It can also cause a green discharge and a strong odor, along with itching on the inner thighs. A doctor will perform a pelvic exam to look for characteristic red spots along the vaginal wall. A round of antibiotic treatment is commonly used to cure the infection.

There are a variety of conditions that can cause a vaginal rash, so it's important to have the condition checked out by a doctor. The doctor will usually take a culture sample from the vagina and examine it in an effort to identify the organism or material that is causing the rash. The most common causes of vaginal rashes are not life-threatening, and the prognosis is good with proper treatment. With the exception of contact dermatitis, most vaginal rashes will not go away on their own and will require antibiotic or antifungal treatment.
