STDs Flashcards
vaginitis
- general term for vaginal infection, inflammation or change in vaginal flora
sx of vaginitis
- discharge- change in volume, color
- pruritis
- odor
- dyspareunia
- dysuria
normal vaginal flora
- mainly lactobacilli
normal vaginal pH in premenopausal women
- 4.0 - 4.5
normal vaginal pH in premenarche or postmenopasual
- 4.7
normal vaginal discharge
- d/c is normal
- is an issue when it causes sx like itching, pain, odor
- normally clear or whiteish
- odorless
- more during mid cycle and pregnancy
things that can impact vaginal discharge
- estrogen- progesterone contraceptives
- diet
- sexual activity
- medications
- stress
bacterial vaginosis
- shift in vaginal flora: decreased lactobacilli and more diverse bacteria
- increased production of amines by new bacteria
- rise in pH > 4.5
what is the most common cause of discharge in younger women
- bacterial vaginosis
major bacterial responsible for BV
- gardnerella vaginalis*
- prevotella spp
