Vaginal yeast infections are one of the most common health concerns for women across Canada. In fact, more than 75% of women will experience at least one yeast infection in their lifetime. About half of those women will deal with repeat infections. Understanding what causes them — and how to prevent them — can make a real difference in your everyday comfort and health.
What Are Vaginal Yeast Infections?
A vaginal yeast infection is caused by a fungus called Candida albicans. This fungus naturally lives in small amounts on the skin and inside the body, including the vagina. However, when something disrupts the natural balance, Candida can grow out of control and cause an infection.
Common symptoms include genital itching, a burning sensation, and a thick whitish-yellow discharge. Some women also experience pain during sex. If you notice these symptoms, it is a good idea to speak with your family doctor or visit a walk-in clinic for a proper diagnosis before starting any treatment.
According to Health Canada, fungal infections like vaginal yeast infections are very treatable. However, prevention is always the better approach, especially for women who experience them repeatedly.
Why Do Vaginal Yeast Infections Keep Coming Back?
Recurring vaginal yeast infections can feel frustrating and exhausting. Several lifestyle factors can tip the balance in favour of Candida overgrowth. These include wearing tight clothing, using scented personal care products, or having an underlying health condition like diabetes.
The good news is that many of these risk factors are within your control. Small, practical changes to your daily habits can significantly lower your chances of a repeat infection. The 10 tips below are backed by health experts and are easy to put into practice.
10 Practical Ways to Prevent Vaginal Yeast Infections
1. Choose Cotton Underwear
The type of underwear you wear matters more than you might think. Cotton is a natural, breathable fabric that allows air to circulate and helps keep the genital area dry. Moisture is one of the main conditions that allows Candida to thrive.
If you prefer other fabrics, look for underwear that has a cotton lining or cotton gusset. Even this small detail can help reduce moisture and lower your risk of vaginal yeast infections. In general, anything that keeps the area dry and well-ventilated is a step in the right direction.
2. Wear Looser-Fitting Clothing
Tight clothing like leggings, skinny jeans, and tight shorts can trap heat and moisture close to the skin. This creates the warm, damp environment where Candida grows best. Therefore, looser-fitting clothes — like flowy skirts or relaxed trousers — are a better choice, especially on warmer days.
You do not need to overhaul your entire wardrobe. Simply being mindful of what you wear on days when you are more prone to sweating can make a noticeable difference over time.
3. Be Careful with Nylon Tights and Pantyhose
Nylon tights and pantyhose trap heat and encourage sweating, which increases moisture around the genital area. As a result, they can raise your risk of a vaginal yeast infection. If you must wear them, look for pairs with a cotton gusset.
The cotton lining helps absorb some of the moisture that nylon would otherwise hold against your skin. It is a small change, but it can offer meaningful protection for women who are prone to recurring infections.
4. Change Out of Wet Clothing Promptly
Whether it is a wet swimsuit after a dip in the lake or sweaty workout clothes after the gym, staying in damp clothing creates the perfect conditions for Candida to multiply. Change into dry clothes as soon as possible after swimming or exercising.
This tip is especially important during Canadian summers when swimming and outdoor activities are part of everyday life. Keep a dry change of clothes in your bag so you are always prepared.
5. Avoid Scented Feminine Care Products
Scented soaps, bath gels, bubble baths, feminine sprays, and scented lotions may smell pleasant, but they can seriously disrupt the natural balance of bacteria and fungi in the vaginal area. These products can irritate the delicate mucous membranes and encourage Candida overgrowth.
Health experts strongly advise against using these products near the genital area. This is especially true for vaginal douches and internal cleansing products. Douching can push fungi further up toward the cervix and uterus, which can actually make a vaginal yeast infection much worse.
For intimate hygiene, warm water and a mild, unscented soap used on the external skin only is all you need. Simple is best when it comes to this sensitive area.
6. Practise Correct Wiping Technique
This tip is simple but very important. Always wipe from front to back after using the toilet. Wiping from back to front can transfer bacteria from the anal area to the vaginal area, increasing the risk of both bacterial and yeast infections.
Teaching this habit early — and reinforcing it — is one of the easiest ways to protect vaginal health over the long term. It takes only a moment but can prevent significant discomfort.
7. Manage Diabetes and Blood Sugar Carefully
If you have diabetes or another condition that raises blood sugar levels, managing it properly is essential for preventing vaginal yeast infections. High blood sugar creates an environment where Candida can thrive, both locally and throughout the body.
Work closely with your family doctor or diabetes care team to keep your blood sugar within a healthy range. In Canada, most provincial health plans cover diabetes management programmes and related care. Proper blood sugar control not only protects your overall health — it also meaningfully reduces your risk of recurring yeast infections.
8. Eat Yogurt and Probiotic-Rich Foods
Your diet plays a surprising role in preventing vaginal yeast infections. Yogurt that contains live active cultures (also called probiotics) may help suppress the growth of Candida. Probiotics are beneficial microorganisms that naturally live in the digestive tract and help keep harmful fungi and bacteria in check.
In addition to yogurt, probiotic-rich foods like kefir, sauerkraut, and kimchi may offer similar benefits. Some women also take probiotic supplements, though it is always best to discuss this with your doctor before starting any new supplement. You can read more about probiotics and gut health on Healthline’s guide to probiotics and vaginal health.
9. Use Antibiotics Only When Necessary
Antibiotics kill harmful bacteria, but they can also wipe out the beneficial bacteria that help keep Candida under control. This is why many women notice a vaginal yeast infection shortly after finishing a course of antibiotics. However, this does not mean you should avoid antibiotics when you truly need them.
Talk to your family doctor about your history of yeast infections when antibiotics are prescribed. In some cases, your doctor may recommend a preventive antifungal treatment alongside the antibiotic course. Never stop a prescribed antibiotic early without medical guidance.
10. Strengthen Your Immune System
A healthy immune system is one of your best defences against vaginal yeast infections. Eating a balanced diet rich in vegetables, whole grains, and fibre, getting regular physical activity, managing stress, and getting enough sleep all support strong immune function.
Women with weakened immune systems — due to conditions like HIV or from taking immunosuppressant medications — face a higher risk of fungal infections. If this applies to you, speak with your healthcare provider about additional protective measures.
When to See a Doctor
Prevention is important, but knowing when to seek medical care is equally essential. See your family doctor or visit a walk-in clinic if you experience symptoms of a vaginal yeast infection for the first time, if your symptoms do not improve after over-the-counter treatment, or if you have more than four infections in a single year.
It is also important to get a proper diagnosis before treating yourself. Symptoms of a yeast infection can look very similar to those of bacterial vaginosis or sexually transmitted infections. Only a healthcare provider can confirm the correct diagnosis and recommend the right treatment. Most provincial health plans across Canada cover visits to your family doctor or a walk-in clinic for this type of concern.

Frequently Asked Questions About Vaginal Yeast Infections
What causes vaginal yeast infections?
Vaginal yeast infections are caused by an overgrowth of a fungus called Candida albicans. This fungus normally lives in small amounts in the vagina, but certain conditions — like antibiotic use, high blood sugar, or hormonal changes — can disrupt the natural balance and allow it to multiply. Wearing tight or non-breathable clothing can also contribute to the problem.
How do I know if I have a vaginal yeast infection?
Common signs of a vaginal yeast infection include intense itching, a burning sensation, redness, and a thick, whitish-yellow discharge that may look like cottage cheese. Some women also experience pain or discomfort during sex or urination. However, these symptoms can also indicate other conditions, so always get a proper diagnosis from your family doctor or walk-in clinic.
Can I prevent vaginal yeast infections naturally?
Yes, several natural strategies can help prevent vaginal yeast infections. Wearing breathable cotton underwear, avoiding scented feminine products, eating probiotic-rich foods like yogurt, and keeping the genital area dry are all helpful steps. These lifestyle changes are not a replacement for medical treatment, but they can significantly reduce the risk of recurring infections.
Are vaginal yeast infections contagious?
Vaginal yeast infections are not considered a sexually transmitted infection, but Candida can be passed between partners during sexual contact in some cases. It is uncommon, but male partners can develop symptoms like redness or itching on the penis. Talk to your doctor if you or your partner experience recurring symptoms after sexual activity.
Does diabetes increase the risk of vaginal yeast infections?
Yes, diabetes is a significant risk factor for vaginal yeast infections. High blood sugar levels create an environment where Candida can grow more easily. Women with diabetes who keep their blood sugar well-managed through diet, medication, and regular monitoring have a lower risk of developing yeast infections. Speak with your doctor or diabetes care team about strategies that work best for you.
When should I see a doctor for a vaginal yeast infection?
You should see a doctor if it is your first vaginal yeast infection, if your symptoms do not improve after using an over-the-counter antifungal treatment, or if you have more than four infections in one year. Your family doctor or a walk-in clinic can confirm the diagnosis and recommend the most effective treatment for your situation.
