yeast infections are totally normal and most women get them at some point in their lives. yeast cells are naturally occurring in the vagina, mouth, and digestive tract, and it only becomes a problem when they get out of control and take over these systems.
if you suspect a yeast overpopulation i think the best thing is to combat it naturally first and see if you can keep balance without resorting to more drastic measures like creams and anti-fungals. these things can make you dependent on harsher methods that may not be necessary.
if you notice some funky discharge
1. wear cotton panties only and give yourself panty-free time as well. tight, synthetic fabrics can further irritate the area and cause more discomfort, and leaving them on for a long amount of time creates a dark, wet space that yeast loves.
2. cut back on your sugar intake and eat plenty of foods with probiotics (good bacteria which help digestion and keep bad bacteria and fungus in balance). yogurt, kefir, kombucha...
3. don't shave or wash your pubic area with any type of soap or feminine wash. water only.
4. try to refrain from vaginal sexual activities until it clears up. also, do not use spit as lubrication.
5. do not take or use antibacterial products unless you have a bacterial issue which surpasses the severity of the fungal issue. antibacterials kill all bacteria indiscriminately, which gives the yeast the opportunity to take over your system.
6. if the yeast infection doesn't go away within a few weeks, if the symptoms are unmanageable, or if the infection is reoccurring, then i would suggest seeing an obgyn or health professional who has experience with female health care.
