Candida Overgrowth Assessment: Clinical Screening Questionnaire
Kerry Watson, NTP, RWPThis clinical assessment is used by practitioners to evaluate the possible role of Candida albicans in contributing to chronic health problems.
Candida albicans is a yeast that naturally inhabits the human digestive tract. When gut health is disrupted — by antibiotics, hormonal changes, stress, or poor diet — candida can overgrow, contributing to chronic symptoms including bloating, brain fog, fatigue, and recurrent infections.
This questionnaire evaluates your medical history and current symptoms to determine whether candida overgrowth may be contributing to your health concerns. Answer each question honestly for the most accurate result.
Disclaimer: This questionnaire is an educational screening tool, not a medical diagnosis. Results should be discussed with a qualified healthcare practitioner. Based on the Crook Candida Questionnaire (Crook, W.G., Chronic Fatigue Syndrome and The Yeast Connection).
To begin, select your biological sex:
Scoring thresholds differ between males and females due to gender-specific questions.
