What causes yeast infections?

Yeast infection is the commonest in women and mostly affects the vagina. Normally, some amount of yeast and beneficial bacteria are always present in the vaginal area. In yeast infection, the proportion of yeast overtakes that of bacteria through multiplication or via some external source. The increased quantity of yeast (known as, Candida albicans) attacks the lining of the organ, causing swelling, irritation, and a thick discharge from vagina.

What causes yeast infections?

A host of combined or single factors account for yeast infections. Lets look:

Immunity

Like in other conditions, a weakened immune system enhances the possibility of developing yeast infection. Reduced immunity could be due to improper diet, excess physical strain, or external factors, such as the influence of certain medicines, e.g., prednisone.

Hormone Replacement Therapy

Either adopted to reduce menopausal symptoms or as contraceptives, hormones taken as supplements can promote yeast infection.

Medication

Certain strong medicines, particularly the antibiotics, taken to fight lung & throat infections, urinary tract infection (UTI), some skin disorders, either wipe out, or greatly reduce the amount of useful bacteria from the vagina also. These bacteria regulate the pH balance by keeping the vaginal area mildly acidic, which is not conducive for the growth of yeast, Candida. As the antibiotics act towards reducing the bacteria, the safe pH balance of the vagina is disturbed too in the process. The yeast gets the opportunity to thrive and starts affecting the surrounding tissues. Although, antibiotics rank among the lead causes of yeast infection, their prolonged usage aggravates the infectious situation.

Diabetes

Diabetes considerably raises the blood sugar level, providing sustenance to Candida, which feeds on various forms of sugar.

Pregnancy

And associated hormonal changes are responsible for the yeast infection.

Hot and humid weather

Such conditions are ideal for the growth of yeast, especially when coupled with tight and closely woven fabric.

Injury

If the internal vaginal tissues are injured, for instance, in the case of chemotherapy, the possibility of developing yeast infection rises. If any other, external or internal, injury confines you to bed or wheelchair, be extra cautious, as yeast thrives in moist and warm atmosphere.

Toiletries and other products

Products such as certain perfumes, anti-bacterial soaps, bath salts, scented sanitary napkins, certain detergent bases, etc. may also prove instrumental in disturbing the vaginal yeast-bacteria balance. Certain spermicidal, such as, nonoxynol-9, can also create bacterial imbalance.

Personal hygiene

Carelessness in the terms of cleanliness and the upkeep of inner wear can cost dearly, as improperly washed fabric may retain the yeast.
