While 75% of women will have at least a yeast infection in their lifetime, up to 8% will have more than four per year. They are called recurrent yeast infections if they occur again and again.

If you are one of those women, you and your doctor may need to take a different approach.

Causes of chronic infections

Recurrent yeast infections are infections that occur four or more times in a year.

Chronic yeast infections can occur when conditions in the body are conducive to yeast overgrowth. An overgrowth of Candida causes the majority of cases of yeast infections. This type of yeast is naturally present in our bodies.

In the vagina, chronic yeast infections can occur if there is an imbalance or a change in the vaginal bacteria. These bacteria normally help prevent Candida overgrowth. An imbalance or variation can occur if too many bacteria are removed through antibiotics or douches. It is vital to have a balance of healthy microorganisms in the body. This is where probiotic supplements or foods like yogurt with active cultures can help. While not accepted as a proven treatment for yeast infections, some people find it useful for promoting healthy vaginal bacteria.

Candida also tends to thrive in humid conditions, such as sweat or saliva. Lack of regular hygiene practices, such as daily showers and brushing teeth, or a constantly humid environment can also lead to chronic yeast infections. You're also at risk for recurring yeast infections if you have a weakened immune system. The following can weaken your immune system:

• age
• some medicines

some health problems

What could happen?

Most yeast infections are caused by a type of fungus (candida) called Candida albicans. Other types of fungi can also cause yeast infections, but antifungal treatments usually target only the most common ones. If your infection is caused by something else, the antifungals used to treat yeast infections may not be effective for you.

Or, while it may seem like you're getting new infections, you may not be the first. Be sure to follow your treatment instructions carefully and complete all of your medications.

Using antibiotics too often can reduce the number of good bacteria in your vagina. This can allow Candida to grow and increase the chances of a yeast infection. The longer you use antibiotics, the more likely you are to get one.

High blood sugar due to uncontrolled diabetes facilitates yeast feeding and growth. Hormonal contraceptives, including oral contraceptives and spermicidal creams and jellies, can alter the bacterial balance in your vagina and allow more Candida to grow.

Wearing wet or tight clothes, such as sweaty gym clothes that you don't take off right away, or a wet bathing suit after a swim creates a warm, moist place that yeast loves.

Eating habits

Although some people believe that certain foods or diets promote yeast growth and lead to recurring infections, there is not enough research to support this theory.

According to the studies carried out, a strict diet does not seem to be useful in preventing them.

Talk to your doctor

Your doctor can help you figure out what's going on, especially if it's another type of infection or a medical condition that's causing your symptoms. An accurate diagnosis is the best way to get the right treatment and find relief.
