Is Your IUD Causing Yeast Infections?

Most literature — as well as gynecologists — will tell women who are experiencing a sharp increase in yeast infections following the insertion of an IUD that IUD's "do not cause yeast infections." Read further, however, and you will not only find one anecdotal story after another from women who have had chronic yeast infections following the decision to have an IUD inserted, but also near-grudging admissions from professionals that while the IUD does not cause yeast infections, it is a substantial "risk factor."

What is a Yeast Infection?

For the lucky-and rare-woman who has never experienced a vaginal yeast infection suffice it to say they can bring on significant levels of through and through misery. Yeast infections are most common in women who are menstruating, and less common in postmenopausal women who have foregone estrogen supplements and younger girls who have not started menstruating. The signs and symptoms of a yeast infection include itching of the vulva and around the vaginal opening, pain on urination or intercourse, reddened and swollen vaginal tissues and vaginal discharge.

What are the Typical Causes of a Yeast Infection?

The fungus responsible for yeast infections (Candida) generally resides in our gastrointestinal tracts, and occasionally in the vagina, but under normal circumstances causes no symptoms or trouble. Sometimes, however, Candida can experience an overgrowth due to antibiotic use, diabetes, a weakened immune system, pregnancy, the use of hormonal contraceptives, contraceptive devices such as vaginal sponges, diaphragms and IUD's, and, in some cases, a partner's use of spermicide. A woman who is very sexually active is more likely to experience chronic yeast infections than one who is less active. Between 5 and 10% of all women will have recurring yeast infections, defined as more than four during a one year period.

How Does an IUD Cause a Yeast Infection?

Scientific studies which have attempted to determine whether the insertion of an IUD can cause a yeast infection look to the ability of the Candida to cling or adhere to the parts of the IUD. They can confirm the adhesion through scanning electron microscopy which clearly shows the Candida cells adhering to at least three parts of the IUD; the tail section, the copper-covered part of the IUD, and to the irregularities of the IUD's surface. The tail especially appears to act as a reservoir for yeast cells. The tail of the IUD is a kind of bridge between the vagina, which is normally populated with yeast cells and the upper genital tract which would generally have no Candida present. The scientific studies definitively showed that IUD users consistently have more yeast cells in the vagina, leading researchers to believe that the IUD predisposes the woman to infections by yeast cells.

How to Treat a Yeast Infection

Although some yeast infections can be successfully treated on your own, it is generally advisable to see a doctor, who will probably prescribe a pill called Diflucan to cure your Candida. There are also over-the-counter creams available which can stop a yeast infection, and are placed inside the vagina with an applicator. Common examples of these creams are Femstat, Mycelex, Gyne-Lotrimin, Monistat or Vagistat. These creams are commonly used at bedtime to avoid the inevitable dripping and leaking. Some women swear by the bacteria found in plain yogurt (used both internally and externally) as a cure for a yeast infection, while others have found good results from taking garlic tabs or a daily dose of apple cider vinegar. Drink your eight glasses of water, and avoid clothing which is too tight in the crotch as well as underwear made of man-made fibers (cotton is best). Most importantly, if you have noticed a sharp uptake in yeast infections following the insertion of your IUD, don't let your doctor tell you it's not possible. Not only is it possible, it is highly likely. You may end up deciding to find an alternative form of contraception to lessen the occurrence of yeast infections.

Thank you so much for this post! I had my IUD put in January 2016 and ever since then had problems. I associated the UTIS and repeated yeast infections to my long distance relationship. Thinking I was in a vicious cycle because I only saw my boyfriend every 1-2 months so then I get a UTI take antibiotics then of course yeast. But by August -October I hadn't seen him did all the right things, probiotics hygienie etc and was getting yeast infections every other eeek. The yeast infection didn't cause dishcharge just made me feel the pain of the IUD. I would take difkucsn feel better than 10-14 days later it was back. It's October and I took out the IUD and instantly feel lighter and healed. It's just not worth it snd doctors rely on their research and research says it's safe and we are wrong. I say follow your gut if you thinks it's the IUD it probably is
