Vaginal burning: what is it and what are the 5 most common causes

Vaginal burning is a common complaint, according to gynecologist Fernanda Vaz (CRM-SC:18.840 – SC), with whom we spoke to learn more about it. In this text, she clarifies the main causes of burning, which can be allergies, diaper rash, skin irritation or even infections. Keep reading and check it out!

1. Allergies and diaper rash

The woman needs to observe herself to see when the symptoms worsen to correlate with situations that may be causing the burning sensation. Some of the products that usually cause this reaction are sanitary pads, certain underwear fabrics, toilet paper, soaps or even the type of fabric softener used to wash clothes, especially the most perfumed ones.

Treatment: when identifying what causes the reaction, it is necessary to stop its use. You may be guided by the gynecologist to use medicines that relieve symptoms, such as anti-allergic or anti-inflammatory ointments.

2. Vaginal infection

Candida sp is a fungus that normally inhabits the vaginal flora, however, in some situations it can proliferate excessively causing candidiasis, which causes itching, burning, redness and a lumpy white discharge. It is common to appear before menstruation and after sexual intercourse, in addition to situations of great stress, wearing very tight clothes, among others.

Other forms of infection that cause vaginal burning include bacterial vaginosis, which causes a yellowish, foul-smelling, burning vaginal discharge, and sexually transmitted infections such as trichomoniasis, gonorrhea, genital herpes, and chlamydia.

Treatment: in these cases, treatment will focus on the causative agent with antifungals, antivirals or specific antibiotics.

3. Vulvodynia

It causes burning in the vagina during intimate contact, in addition to other uncomfortable symptoms such as pain, irritation and redness. It is a chronic and recurrent disease. Its etiology is not yet fully defined, but it seems to be caused by pelvic floor and hormonal dysfunctions.

Treatment: There is no definitive treatment. Some options include the application of topical anesthetics, the use of antidepressants or antiepileptics that relax the muscles. In addition, psychotherapy or sexual counseling is indicated.

4. Urinary losses

Urinary incontinence and consequent contact of the skin of the intimate region with the urine accumulated in the panties or absorbent, can generate ammoniacal dermatitis (it is also very common in children in diapers). This leads to inflammation of the skin at the site and burning sensation.

Treatment: in these cases, try to wear panties made with easily breathable fabric such as cotton, avoid tight clothing and always do good local hygiene. In addition, there are pelvic physiotherapy techniques that can help in mild to moderate cases, and surgical treatment may sometimes be necessary.

5. Skin diseases

Some dermatological problems can also affect the skin of the vulva and vaginal mucosa. This can lead to injuries and burning. Lichen planus and lichen simplex are the most frequent, especially in women over 40 years of age.

Treatment: A gynecological consultation is required for diagnosis through physical examination and biopsy to define the appropriate treatment.

Fernanda also highlights that burning in the vagina after sexual intercourse is also common, most often caused by excess friction during the act, especially when there is a decrease in vaginal lubrication, whether due to hormonal or psychological factors, but also due to lack of adequate sexual stimulation before penetration occurs. There are also cases of allergy to condoms, especially latex or even allergy to semen.

Through gynecological consultation, conversation and physical examination, it is possible to arrive at a cause and draw up a treatment plan. Did you like the information? Enjoy and understand the reasons for vaginal itching and how to avoid it.
