Candida Long Questionnaire

This is the long questionnaire designed for adults and isn’t appropriate for children. It is based on a questionnaire created by William G. Crook M.D. and his book The Yeast Connection. Modifications have been made to suit our clientele. It is appropriate to fill this out questionnaire every two years or so, and check if the risk factors or symptoms related to Candida have increased enough to consider it an issue. There is a shorter questionnaire also. It helps keeps track of your symptoms on an ongoing basis. It can tell you when you are finished with the Candida problem.

This questionnaire lists factors in your medical history which can promote the growth of Candida albicans (Section I) and symptoms commonly found in people that have a Candida problem (Sections II and III). If the question applies in Section I, circle the number and add the score. In Sections II and III you are asked to rate symptoms. By adding all these numbers together we can derive the probability of having a Candida (yeast) problem. This questionnaire is not definitive. On its own, it cannot determine with absolute certainty whether or not you have a problem.

Grand Total Score (Add Sections I, II and III)  



  1. If your score is over 175, almost certainly Candida is a contributing factor to your health condition.
  2. If your score is over 120, it is likely that Candida is causing some health issues.
  3. If your score is between 60-120, Candida possibly contributes to your health but in a minor way.
  4. A score less than 60 means that Candida is not causing a problem significant enough to treat.


For males the score is downgraded a bit; above 100 puts you in category 1; 80-100 category 2; 50-80 category 3 and below 50 categorized as not of any concern.

We start treating females if above 120 and males if above 80.

Please refer to the Candida Diet for a recommended program.
