When undergoing a candida cleanse, common side effects include nausea, headaches, and dizziness, according to The Candida Diet. Other more serious side effects are fever, hives, and recurrent prostate, vaginal or sinus infections.
A die-off, or "Herxheimer" reaction, is common when a fungal parasite is treated, reports The Candida Diet. This reaction is characterized by mild flu-like symptoms, such as fever or aches, but also includes allergic responses. Such a reaction is caused by rapid die-off of the candida fungus, resulting in a massive amount of toxic cell contents to be expelled into the human body. Seventy-nine different toxins, including acetaldehyde and ethanol, are released by the candida fungus upon its death. Acetaldehyde release is held responsible for the majority of the side effects of candida treatment. This chemical can kill brain cells, and impairs oxygen circulation, thus causing headaches, dizziness and fatigue.
Other toxic chemicals released by a candida die-off cause more symptoms because of inflammatory responses and allergic reactions, adds The Candida Diet. Swollen glands and joints are common inflammatory responses, but heart rate and body temperature can also be elevated. Skin issues such as breakouts, hives or itchiness are common allergic reactions. Recurring infections of the prostate, vagina or sinus may occur, as well as gastrointestinal issues, such as diarrhea or bloating. Often these side effects can be managed with a reduction in anti-fungals and probiotics.
