Vaginitis is an inflammation or infection of the vagina that results in irritation, discharge, and discomfort. It can be caused by bacterial infections, yeast overgrowth, sexually transmitted infections, hormonal changes, or chemical irritants such as soaps, douches, or hygiene products. Common symptoms include itching, burning, unusual discharge, odor, redness, and pain during urination or sexual activity. Vaginitis can affect individuals of any age and may be acute or recurrent depending on the underlying cause. Because symptoms can overlap with other vaginal or reproductive health conditions, medical evaluation is important to identify the specific cause and address potential complications.
