Yeast infections, or vaginal candidiasis, occur when there’s an overgrowth of the normally occurring micro-organisms found naturally in the vagina and the gastrointestinal tract. This infection is very common for people with vaginas and is not sexually transmitted. Factors like taking antibiotics, hormonal contraceptives, or using contraceptive devices can contribute to this imbalance.
Vaginal yeast infections, also known as “Candida vaginal infections,” are primarily caused by the Candida albicans fungus. A significant number of women, up to 75%, will experience at least one vaginal Candida infection in their lifetime, with up to 45% experiencing two or more. Factors such as stress, hormonal changes, or health conditions like diabetes can increase susceptibility.
A common misconception is that yeast infections are prevalent only in younger, pre-menopausal women. However, they can still occur post-menopause, particularly in those undergoing hormone therapy. The organism Candida albicans is often responsible, found naturally in the vagina, mouth, and digestive tract.
Yeast infections can develop if the skin is damaged or in warm, humid conditions. They can also be a consequence of a weakened immune system. Antibiotics, by killing healthy bacteria that balance yeast levels, can inadvertently cause an overgrowth of yeast.
Recurrent urinary tract infections (UTIs) can be frustrating, with 25% to 30% of women experiencing a return of the infection within six months. Contrary to some beliefs, recurrent UTIs are not typically due to poor hygiene but can occur due to various factors beyond one’s control.
Treatment for yeast infections may include antifungal medications. It is essential to consult a healthcare provider for an accurate diagnosis and appropriate treatment. Lifestyle changes, such as maintaining good hygiene, wearing breathable clothing, and avoiding irritants, can also help prevent infections.
