Vaginal discharge is a natural part of the female reproductive system. It comes from the cervix and vaginal walls, with each woman having slight differences in texture, color, and amount.

Healthy discharge is usually “clear or white, watery, and sticky,” like egg white. It may leave yellowish or whitish stains on underwear when dry, which is normal unless there’s itching, burning, or a strong smell.

This fluid keeps the vagina clean and hydrated. It’s made of mucus, dead cells, bacteria, and fluids, acting as a protective barrier—“similar to saliva in the mouth.”

Changes in discharge may signal infections. A thick, lumpy discharge could point to a yeast infection. A fishy smell may suggest bacterial vaginosis, while yellow or green foamy discharge may mean trichomoniasis.

If you notice bleeding, pain during urination, itching, or unusual changes in discharge, it’s best to see a doctor. Understanding what’s normal helps detect problems early and protect reproductive health.
