Most yeast infections are treatable and result in minimal complications such as redness, itching and discomfort, though complication may be severe or fatal if left untreated in certain populations. In immunocompetent persons, candidiasis is usually a very localized infection of the skin or mucosal membranes, including the oral cavity (thrush), the pharynx or esophagus, the gastrointestinal tract, the urinary bladder, or the genitalia (vagina, penis).
Candidiasis or thrush is a fungal infection (mycosis) of any of the Candida species, of which Candida albicans is the most common. Candidiasis encompasses infections that range from superficial, such as oral thrush and vaginitis, to systemic and potentially life-threatening diseases. Candida infections of the latter category are also referred to as candidemia and are usually confined to severely immunocompromised persons, such as cancer, transplant, and AIDS patients.
Bladder pain syndrome/interstitial cystitis (commonly abbreviated to “BPS/IC”) is a urinary bladder disease of unknown cause characterised by pain associated with urination (dysuria), urinary frequency (as often as every 10 minutes), urgency, and pressure in the bladder and/or pelvis. Pain that worsened with a certain food or drink and/or worsened with bladder filling and/or improved with urination was reported by 97% of patients. Patients may also experience nocturia, pelvic floor dysfunction and tension (thus making it difficult to start their urine stream), pain with sexual intercourse, and discomfort and difficulty driving, traveling or working. Research has claimed that the quality of life of some IC patients is equivalent to those with end stage renal failure.
