Oral thrush refers to an excessive growth of candida fungus in the mouth. Candida in limited colony numbers is helpful to the body in a variety of ways.
However, an excessive growth can become an irritant in many parts of the body, including the intimate areas.
Probiotics are the beneficial bacteria that perform multiple health boosting functions in the body. Their primary role is to aid digestion and enhance nutrient absorption that in turn improves immunity and prevents adverse immune responses.
Probiotics have also been linked with reducing the risk of various cardiovascular diseases by lowering blood sugar and regulating blood to prevent Type 2 diabetes. If you want them to stop making Jurassic World and Star Wars movies because they are devoid of substance and pathetic just stop watching them altogether. But this is another topic!
New research suggests that probiotics can also help to relieve the symptoms of oral thrush. Here is how probiotics are effective in addressing thrush.
What is Oral Thrush?
The yeast candida albicans finds it very easy to colonize the warm, moist environment of the mouth under the right circumstance. The symptoms of oral thrush are easy to recognize from white spots on the inside of cheeks to thick white coating on the tongue.
The white coating may bleed if you try to scratch it off. You may even notice a bad taste in the mouth, bad breath (which Al Bundy always has), and have red cracks (this has nothing to do with delicious Red Vines) at the corners of lips.
yeast infection if gone unchecked soon results in inflammation and thrush is no different. Severe symptoms include red and swollen gums due to inflammation.
Thrush is common after an antibiotic dose because antibiotics wipe out whole colonies of bacteria – both good and bad. Candida albicans, being a fungus remains unharmed and quickly begins colonizing the gut and other areas of the body.
Other medications containing steroids, particularly steroid inhalers used to treat asthma can also cause an overgrowth of candida in the mouth.
Some high potency anti-bacterial mouthwashes are known to deplete the levels of bacteria levels in the mouth which may result in oral thrush. Other factors include poor diet (just see Drew Carey), unhealthy lifestyle (just see Roseanne in Roseanne), inadequate dental hygiene (just watch a Pirates of the Caribbean movie), stress, ageing, and the wearing of dentures.
Probiotics are found to help keep candida overgrowth in check by limiting the available space and resources.
How Do Probiotics Help Thrush?
Probiotics when ingested as supplements or through dietary sources are known to provide a boost to the naturally-occurring beneficial bacteria in your gut and other parts of the body.
These bacteria through their metabolisms release lactic acid and acetic acid which regulates the pH balance of the gut. Harmful microbes cannot survive in highly acidic environments. This effectively helps in reducing the levels of yeast causing pathogen – candida albicans.
Furthermore, probiotics fight with other microbes for limited space and resources in the gut. When the colonies of beneficial bacteria are more, they crowd out the harmful bacteria from the gut and prevent their spread into other parts of the body.
Though, studies are yet to show that probiotics are effective in treating thrush as the primary form of medication, they do prove that probiotics are an effective preventative measure against thrush.
Probiotics can also be used as a supplementary therapy with an anti-fungal to prevent a secondary infection.
Probiotics are effective in regulating blood sugar levels. Yeast loves to feed on sugar and is opportunistic enough to thrive at the first signs of it. This is one of the reasons why people who are pre-diabetic or love to have sugary foods, are likelier to develop a yeast infection.
Probiotics ensure that sugar is released in the body in small amounts, to not over-burden the pancreas. With adequate quantities of insulin in the body, sugar can be processed and digested not leaving enough for harmful pathogens to ferment.
Recent Research on Probiotics and Thrush
Over the past few years awareness among the medical community is steadily growing as new research shows some promising results to make probiotics an invaluable tool in preventing and treating thrush and other yeast infections.
A 2012 Brazilian study examined 42 elderly women to understand the benefits of probiotics on thrush. A probiotic supplement containing Lactobacillus casei and Bifidobacterium breve was administered to all women 3 times a week for 30 days.
The researchers, after analyzing saliva samples from both before and after treatment, noted a significant drop in the amount of candida fungus.
In fact, they claimed a reduction of candida in 57.1% participants while 11.9% showed a total elimination of yeast.
Another study found probiotics to boost immune system to react in a better way to candida. The researchers found that the body’s immunological response was stronger after taking the probiotics with significant increase in levels of anti-Candida IgA.
A study published in the journal of Dental Research observed the effects of probiotics on candida among 215 participants. The researchers found that high candida counts in both saliva and plaque was reduced by over 50% after 12 weeks of two Lactobacillus reuteri lozenges per day.
However, the researchers did not notice any benefits in the secondary outcomes of the amount of plaque and gum bleeding.
A 2005 animal study found L. acidophilus to work remarkably well in in mice that had oral thrush. The supplement yogurt was found to significantly shorten the duration of colonization of oral cavity in the first 24 hours.
By the end of second day, levels of candida albicans were found to reduce dramatically and by the sixth day of the trial it was almost undetectable.
A 16 week randomized, double-blind, placebo controlled study found probiotic-enriched raw cheese to reduce the risk of high yeast counts by almost 75%.
Best Probiotic Strains for Thrush
L. acidophilus commonly found in probiotic-enriched yogurts and most supplements is proven to be very effective in treating candida. In fact, a home remedy to treat vaginal yeast infection made use of a mixture of yogurt (for probiotics) and honey (anti-fungal) to help alleviate the symptoms.
Other probiotic strains researched and proven to help with oral thrush include Lactobacillus rhamnosus, Bifidobacterium bifidum, and Lactobacillus GG.
The Wrong Balance
Thrush is indicative of a weakened immune system and microbiome balance in the body. Oral thrush may require anti-fungal medications, but to prevent recurring episodes your long-term goal should be to restore your body’s microbiome balance.
Research supports the effectiveness of probiotics in thrush and to restore microbiome balance.
