Doctor's Notes on Every Thing You Need to Know about Yeast Infection (Candidiasis)

The signs and symptoms of candidiasis, a common yeast infection, depend on the location of the infection, immune status of the person, and/or the person's sex. Examples are given below.

  • Oral candidiasis (also termed thrush): thick white lacy patches on top of a red base almost anywhere inside the mouth and the tongue may look red without the white coating
  • Candidiasis on the skin: It mainly occurs in warm and moist areas such as diaper area and/or skinfolds as a red flat reddish area with sharp scalloped edges; the areas may be itchy and/or painful.
  • Candidiasis associated with people who have weakened immune systems: Oral candidiasis may extend into the upper gastrointestinal tract and may produce ulcers, nausea, vomiting, and chest pain and make it difficult to swallow foods and liquids.
  • Blood-borne candidiasis: possible fever, mental status changes
  • Genital candidiasis: Signs and symptoms of this in women include a thick white discharge resembling cottage cheese, itching and irritation of the vagina and surrounding tissue, burning with urination, and/or discomfort and pain with sexual intercourse. In men, symptoms and signs include itching and burning of the penis and a reddish rash on the skin of the penis.

The cause of candidiasis is usually a yeast infection by Candida albicans. These yeast commonly are found on the skin and mucosal surfaces of healthy individuals. Yeast cause infections when local conditions (cracks in skin, skin is kept included and/or wet or damp, individuals have poor or depressed immune response) encourage rapid yeast growth.
