Vaginal discharge is a natural secretion from the cervix and vaginal walls, essential for maintaining vaginal health. In healthy women, it is typically clear or white, watery, and slightly sticky, resembling egg whites. Its appearance, texture, and odor can vary among individuals. When dried on underwear, the discharge may leave a whitish or yellowish crust—this is entirely normal, as long as it has no strong odor and isn’t accompanied by symptoms like itching or burning. The discharge’s composition includes secretions from uterine tissues, dead epithelial cells, blood vessel fluids, and beneficial bacteria. Sebaceous and sweat glands near the vulva also contribute. This fluid keeps the vaginal area hydrated and clean, functioning as a natural defense much like saliva in the mouth.

However, certain changes in vaginal discharge may signal an underlying condition. A lumpy texture can suggest a yeast infection, while a fishy-smelling odor may indicate bacterial vaginosis. Yellow or greenish, foamy discharge is characteristic of trichomoniasis. Warning signs that warrant medical attention include bleeding, pain during urination, irritation, sudden increases in volume, or changes in color, odor, or consistency. While regular discharge is a sign of a healthy reproductive system, any unusual symptoms should prompt a consultation with a healthcare provider. Understanding what is normal can help identify when something is wrong and ensure timely treatment if necessary.
