The basics

What you're actually dealing with

A vaginal yeast infection happens when Candida — a fungus that normally lives in small, harmless amounts in the vagina — overgrows and tips the local balance out of order. The result is the intense itching, thick white discharge, and raw, irritated feeling that make a yeast infection so distinctive.

They're remarkably common: roughly three in four women will have at least one in their lifetime, and many will have more than one. A yeast infection is not a sexually transmitted infection, and it's not a sign of poor hygiene — it's an overgrowth of something that was already there, usually nudged along by antibiotics, hormones, or a warm, moist environment.

The reassuring part: an uncomplicated yeast infection is one of the most treatable problems in medicine. A single antifungal pill or a short course of antifungal cream usually clears it, and most people feel noticeably better within a few days. This library walks you through the whole picture — what to look for, what causes it, how treatment works, and how to tell yeast apart from the infections it's so often confused with.

Common questions

The questions people ask most when a yeast infection first shows up.

The giveaway is intense vaginal itching with a thick, white, odorless discharge — often described as looking like cottage cheese — along with redness and irritation. If those line up and there's no fishy smell, a yeast infection is very likely.
Our symptoms guide walks through every sign in detail.
A very mild one occasionally settles on its own, but most don't — and waiting usually means more days of itching and irritation. A short antifungal course clears it reliably, so there's little to gain from toughing it out.
Usually the same day. You complete a short online visit, a licensed clinician reviews it, and if appropriate your treatment is sent to a pharmacy near you — often within a few hours.
Neither. A yeast infection is an overgrowth of Candida that already lives in the body — not something you catch from a partner, and not caused by being unclean. Anatomy, antibiotics, and hormones drive it far more than hygiene ever could.
Antibiotics clear bacteria you want along with the ones you don't. The protective vaginal bacteria that normally keep Candida in check get knocked back, and yeast takes the opening to overgrow. New itching and discharge after a course of antibiotics is a common, recognized pattern.
