vag

Vag is a colloquial shorthand for vagina, the muscular canal that forms part of the female reproductive system. The term is informal and is not typically used in formal medical writing, where the full term vagina is preferred.

Anatomy and function: The vagina extends from the vaginal opening to the cervix and is usually about 7 to 10 cm long. It lies between the urethra and rectum and works with the uterus, ovaries, and external genital structures. Its primary functions are to provide a passage for menstruation, sexual activity, and childbirth. The vaginal wall is composed of mucosa and layered muscles that allow elasticity and expansion.

Vaginal health: The vaginal environment is maintained by normal flora, dominated by lactobacilli, which produce lactic acid and help keep the pH around 3.8 to 4.5. Hormonal changes, antibiotics, and sexual activity can alter this balance. Common conditions include bacterial vaginosis and vulvovaginal candidiasis (yeast infection), which may cause discharge, odor, itching, or irritation. Other infections or irritants can also affect vaginal health. If symptoms arise, evaluation by a healthcare provider is recommended.

Hygiene and care: Avoid douching and intravaginal products unless advised by a clinician. Clean the external genital area with plain water or mild, unscented products. Use condoms for protection against sexually transmitted infections; seek routine gynecologic care and vaccinations as appropriate.
