Causes of Thrush

10 Most Common Causes Of Thrush

When your vagina is healthy, the occurrence of natural bacteria and yeast is balanced.  Both yeast and bacteria are essential to your vaginal health. However, this balance is easily upset which can allow yeasts to overgrown leading to thrush. We have listed the top ten reasons by any of the following factors which could allow the yeasts to overgrow, leading to thrush infection.

How does the yeast infection occur?

A Poor Diet
If you aren’t eating and living well you could be opening yourself up for a thrush infection. Eating foods high in sugar such as sweets, dairy products, coffee, tea and alcohol increase the amount of sugar in your urine. This in turn can encourage the  growth of yeast in your vagina leading to a yeast infection.  

A Course Of Antibiotics
Antibiotics kill the bacteria which are making you ill – but they also kill the good bacteria at the same time. By killing the friendly bacteria in the vagina which help to keep the yeast growth under control, antibiotics can help cause thrush. The underlying illness which had you taking antibiotics in the first place can also weaken your body which can in turn give yeast an opportunity to flourish.

Falling Pregnant
It’s no news to anyone that hormone levels change during pregnancy, but that initial rush of hormones after conception can lead to thrush. Your vagina may secrete high levels of sugar and create the perfect environment for a yeast infection.

Your Period
Menstrual blood will change the acidity of the vagina. Using tampons and towels, particularly for long periods of time, change the pH level of your vagina and can upset the balance. It is generally a moist warm environment during your period and can be the opportune time for an imbalance between bacteria and yeast resulting in a yeast infection.

If you suffer from diabetes you will have an increase in blood sugar levels. This will also increase the sugar levels in your vaginal secretions. Diabetic women also tend to have high sugar levels in their urine all of which can contribute to thrush by feeding the yeast colonies living in your genital area.

Taking The Contraceptive Pill
While this is still a subjective debate as all women are different, it would appear there is a trend indicating that a high dose contraceptive pill may also cause thrush while a low dose contraceptive pill will not.
Talk to your doctor about your concerns and symptoms.

Emotional And Physical Stress
Stress, both emotional and physical, will affect your immune system. If your immune system is weakened you may be more susceptible to an outbreak of thrush as the delicate balance in your vagina may be affected.  

Chemotherapy weakens your immune system, making you more prone to thrush.  
Sexual Intercourse
If you are having a lot of sexual intercourse you may find that the stimulation to the genital area changes the balance of bacteria and yeast. When the balance is upset, you may find yourself more prone to outbreaks of thrush.   

Perfumed Soap
Perfumed products such as soaps and bubble baths can affect the natural pH of the vagina. These products can increase the risk of thrush because they disrupt the natural growth of yeast and bacteria.

What To Do If You Have Thrush

If you have had thrush before and recognise the symptoms go to your pharmacist and discuss your condition. They may or may not recommend you seek a doctors advice. If you are unsure visit your doctor to get a diagnosis and they will discuss treatment options with you.

Always seek medical advice from a health care professional.
