Vaginitis refers to inflammation of the vagina, characterized by itching, unusual discharge, a burning sensation, and sometimes an unpleasant odor. These symptoms vary depending on the type of infection. Bacterial vaginitis causes a grayish, fishy-smelling discharge. Vaginal yeast infection causes a thick, white discharge accompanied by intense itching. Trichomoniasis, a sexually transmitted infection, causes a yellow-green, frothy discharge.
Vaginitis most often results from an imbalance in the protective vaginal flora. Bacterial, fungal, or parasitic infections are the direct causes. Contributing factors include: hormonal imbalances, use of irritating products, inadequate or excessive intimate hygiene, and unprotected sexual intercourse. Antibiotics and hormonal contraceptives can also disrupt the balance of the vaginal microbiome and promote inflammation.
The appearance of vaginal discharge helps guide the diagnosis. Bacterial vaginitis is characterized by gray discharge with a fishy odor, which is often more pronounced after sexual intercourse. Yeast vaginitis produces thick, white, odorless discharge accompanied by severe itching. Trichomoniasis produces a yellow-green, foamy discharge with severe vaginal irritation. These symptoms help guide the clinician, but only a vaginal swab can provide a definitive diagnosis and allow for targeted treatment.
Treatment targets the identified causative agent. Antibiotics—metronidazole or clindamycin—treat bacterial vaginosis and trichomoniasis. Antifungal suppositories or creams treat Candida vaginitis. Probiotics containing lactobacilli restore the protective flora after each treatment. Under no circumstances should self-medication precede a medical diagnosis, as this risks treating the wrong cause and worsening the imbalance.
Proper intimate hygiene is the first line of defense. Avoiding vaginal douches, scented soaps, and irritating products helps preserve the natural flora. Wearing cotton underwear and avoiding tight-fitting clothing reduces maceration. Practicing safe sex reduces the risk of sexually transmitted infections. A diet low in refined sugars and rich in fermented foods supports the balance of the vaginal microbiome and limits the proliferation of pathogens.
Yes. Recurrent vaginitis occurs when contributing factors are not addressed or when treatment is not completed. Stopping treatment prematurely as soon as symptoms disappear increases the risk of a rapid relapse. Reevaluating personal hygiene habits, the products used, and hormonal factors—in parallel with treatment—significantly reduces the likelihood of recurrence.
During pregnancy, hormonal changes increase susceptibility to vaginitis. Untreated bacterial vaginosis is associated with an increased risk of preterm birth and low birth weight. After childbirth, hormonal fluctuations and changes in the vaginal flora also increase the risk of postpartum vaginitis. Any pregnant woman experiencing symptoms should seek prompt medical attention for safe and appropriate treatment.
A medical consultation is necessary as soon as symptoms first appear, if symptoms worsen despite treatment, or during pregnancy. The presence of fever or pelvic pain requires urgent specialized evaluation. Ignoring vaginitis increases the risk of secondary vaginal infections, fertility problems, and sexually transmitted diseases—all of which are preventable with prompt and thorough medical care.
