It’s hard to live in a living world without some living organisms taking residence on or inside of your body. It might not be the most pleasant idea, but everyone is carrying bugs of some sort. Harmful organisms in the intestines and bacteria in the gut are among the most common. Another is Candida albicans. If you’ve ever experienced a yeast infection, then you probably know this one well. Although everyone has Candida, problems are unlikely to arise if it’s kept in balance. However, if an imbalance occurs, so may a yeast infection. Yeast infections can affect the mouth, skin and genitals (and that includes women AND men) and range in severity from inconvenient and uncomfortable to life-threatening. Additionally, overgrowth in the gastrointestinal tract may be a catalyst for serious problems if the fungus enters the blood stream.
Let’s take a look at a few other must-know facts about yeast infections.
1. Yeast Infections May Occur Orally
Gross. Really? Yes, oral yeast infections are commonly called thrush. This infection is common in newborns but typically passes quickly. Babies are not the only ones affected, a recent study found that oral Candida overgrowth occurs in one out of every four adults. Poor oral hygiene is often a primary factor. Researchers identified the presence of plaque, tartar, and amalgam fillings as significantly related to the degree of Candida present. The best defense? Proper, and regular, oral hygiene.
2. Vaginal Yeast Infections Can Be Tricky
Practicing good hygiene is a very good deterrent for yeast infections. However, this isn’t always the case. Frequent douching has been associated with higher incidences of yeast infections. So has wearing tight nylon or synthetic underwear. Oddly enough, over-the-counter anti-fungal medications have also been associated with stubborn occurrences of vaginal candiadosis.  The use of intrauterine contraceptive devices also show a statistically significant increase in Candida infection. 
3. Use of an Asthma Inhaler May Contribute to Candida
A Brazilian study of adults using inhalers for longer than 6 months identified oral candidiasis as one of several adverse effects.  Anyone using an inhaler, or any other oral appliance (such as mouth guards, retainers, or dentures) should be aware of the possibility of Candida exposure.
4. Candida Naturally Occurs On and In Humans
Microbiota like Candida occur naturally on human skin and in the human gastrointestinal tract. In healthy individuals, the immune system and symbiotic bacteria help keep these fungal species in check. Not surprisingly, persons with compromised immune systems are among the most susceptible to Candida overgrowth.
5. The Connection Between Diabetes and Candida
Individuals with diabetes are more likely to develop genital yeast infections, both women and men. The high blood glucose levels of diabetics encourage yeast growth. And, because it inhibits immune response, the risk of recurring infection is higher. Women are more likely to suffer infection from Candida alibicans and Candida glabrate. Uncircumsized men may experience infection from Candida balaritis.
