What are the symptoms of Candida and how can I get tested for it?

Unfortunately, there aren't any reliable tests for an overgrowth of candida, as it is a normal resident in every human being and candida tends to migrate, so chances of getting an accurate sampling is difficult, if not impossible, and highly inaccurate at best.

William Crook, M.D. realized that most patients could only be diagnosed by observing their symptoms along with a questionnaire of their medical history. The most common symptoms and Dr. Crook's questionnaire are below.

Candida Overgrowth symptoms are so numerous and seemingly unrelated that they can be confusing to both doctor and patient. The majority of people who have Candida do not realize they have it until they become seriously ill. Why? Because candida yeast not only steals nutrients from the food that you eat, it then poisons the tissues with waste material containing over 75 known toxins. Candida albicans is linked, directly or indirectly, to the following list of conditions and symptoms. A "symptom" is an outward sign that points to a deeper problem.
