Too many yeast in the intestines lead to a number of problems in Lyme disease. Here are a few.
There is not a useful diagnostic blood test or stool test for yeast overgrowth. While some may test for antibodies in the blood to intestinal yeast. Yeast antibodies are common even when yeast are in balance. In addition, it is normal to have stool cultures grow yeast; so a culture does not indicate if yeast are in excess. For this reason, yeast are diagnosed using a yeast screening questionnaire. This questionnaire evaluates for the possibility of yeast overgrowth based on yeast overgrowth risk factors and intensity of symptoms. In general, based on my experience, people benefit from treatment if the score is 140 or higher.
Often before antibiotics are started in a Lyme disease treatment it is essential to treat yeast. Doing so can limit the severity of Herxheimer die-off reactions from treating Lyme. This is because removing yeast removes one source of inflammatory cytokine excess.
Note: If a person has a sudden decline after doing better, there is a good chance yeast is the cause. The excess cytokines triggered by yeast give most of the same symptoms that occur in Lyme disease. So yeast can imitate a Lyme decline.
The yeast screening questionnaire is not reliable in the middle of treatment. I make a decision to treat yeast in this situation based on symptoms.
Symptoms of yeast in the middle of treatment include:
You do not have to have all of these symptoms to diagnose too many yeast. If a person has a number of these with a decline, then there is a strong possibility of intestine yeast overgrowth.
