Don't let a common fungus disrupt your well-being. Understanding what causes candida overgrowth is the first step toward effective prevention and finding the right yeast infection treatment.

What are the main causes of Candidiasis?

  • A compromised immune system from illness or certain medications can allow the normally harmless Candida yeast to multiply and cause an infection.
  • Recent or prolonged use of broad-spectrum antibiotics often disrupts your body's natural balance of microorganisms, encouraging problematic fungal overgrowth.
  • Uncontrolled diabetes or a diet consistently high in sugar and refined carbohydrates can feed the yeast, leading to an overgrowth and infection.

Key symptoms of Candidiasis to watch for

  • Oral thrush is a classic sign, appearing as creamy white lesions on your tongue or inner cheeks that can be painful.
  • Genital yeast infections cause intense itching and irritation; women may see a thick discharge while signs of yeast infection in men include redness.
  • A candidiasis skin rash can develop in moist skin folds, appearing red and itchy with small blisters, particularly under the arms or in the groin.

How can you prevent Candidiasis effectively?

  • Following a balanced diet, such as a low-sugar anti-candida diet food list, helps limit the yeast's primary food source and supports gut health.
  • Practice good personal and oral hygiene by keeping your skin clean and dry, especially in areas prone to moisture, to discourage fungal growth.
  • Manage underlying health conditions like diabetes effectively and only use antibiotics when absolutely necessary to maintain your body's natural microbial balance.
