Candida, Antibiotics, Allergies and Asthma

Candida, Antibiotics, Allergies and Asthma

It’s not surprising to learn that antibiotics cause fungal candida. This study and many others repeatedly confirm that antibiotics are the cause of this and many other conditions in the body. What is alarming to read is the rate at which allergies and asthma have increased with runaway antibiotic usage.


From 1980 to 1994, the asthma rate increased by 75% in adults and a whopping 160% in children ages 0-4. By destroying the intestinal flora that is crucial to health, antibiotics expose people to a growing list of diseases and life-threatening conditions – asthma, allergies, diabetes, obesity, cancers, life-threatening colitis, Alzheimer’s, Parkinson’s, etc. Antibiotic-induced changes to the microbiota of the intestinal tract can create asthma and allergies without fungal candida even being introduced into the airways and tissues of the lungs. This effect is created by white blood cells that reside in the intestinal tract and travel to the lungs.

Fungal candida has an amazing ability to manipulate immune responses within the body. It’s tendency is to drive Th2-mediated immune responses, as Th1-mediated immune responses are known to actively work towards eliminating and controlling candida. Th2 responses on the other hand will drive allergies and asthma.

People looking to associate past antibiotic usage with present conditions are often mislead by the time these conditions take to manifest. Most people look for a direct cause-effect. They expect that if antibiotics were to cause a problem, it would happen within a few days of receiving antibiotics. That seldom matches the real-life situation, however. It can take weeks to years for some of these conditions to manifest. It is this lag time in the cause-effect relationship that creates many misunderstandings on the side of doctors and patients alike.This study was an example of the short-term cause-effect.

“.. mice were first treated with a short course of a broad-spectrum antibiotic (cefoperazone for 5 days) in the drinking water to decrease total bacterial microbiota followed by a single oral gavage dose of C. albicans to establish a reproducible, low-level elevation of yeast in the microbiota. Greater than 99.95% of the C. albicans colonies cultured at day 1 after gavage were found in the GI tract, with <100 CFU in the oral tissue and no detectable yeast in the lungs. C. albicans could not be cultured from the lungs at any time point examined in these studies, nor could we culture any bacteria from the lungs. This protocol for antibiotic treatment and gavage reduced culturable anaerobic and enteric bacteria levels in the gut by 99.99% at day 4 of antibiotic treatment and resulted in elevated C. albicans levels in the GI tract.”

From this study, we see not only had the antibiotics wiped out all but .01% of the bacteria in the intestinal tract, but it had also wiped out all the bacteria normally found present in the lungs within a period of 4 days. Other studies have shown that 5- and 7-day courses of antibiotics will destroy all the bacteria present in the intestinal tract, leaving only antibiotic-resistant strains.

While this study demonstrates once again the concrete link between antibiotics and fungal candida and their role in creating lung diseases, it stops short of where other studies pick up. Once candida is created through antibiotic use, it spreads throughout the body and plays a role in causing or contributing to many other diseases. As of now, the list of candida-related symptoms is extensive. Diseases that have been associated with candida include diabetes, multiple sclerosis, arthritis, yeast infections, hypertension, immune system suppression, cancers, and more.
