Candidiasis (yeast infection)
Also called thrush, this common infection affects many women whether they are
sexually active or not. Candida is a yeast or fungus that is commonly present in
the bowel and vagina, and less commonly inside the mouth. Problems arise if the
yeast multiplies, especially in the vagina, where it causes a white and
sometimes curd-like discharge as well as intense itching or burning. Candida thrives well in damp places, especially if the
skin is broken
or
sugar levels in the blood are high.
How does Candidiasis develop?
Normally, a healthy bacteria called lactobacillus is present in the vagina and
keeps the unwelcome candida at bay. However, if the
balance between these is
upset, yeast may develop. This can happen after taking antibiotics, which may
destroy many of the normal bacteria, as well as unhealthy bacteria, and this
allows candida to multiply. Women with diabetes often develop thrush because of
the high sugar levels in their urine and vaginal secretions. This may also be
why some women are prone to thrush after consuming a lot of sweet foods or
alcoholic drinks.
In people who have a weakened
immune system
because of
cancer treatments, steroids, or diseases such as AIDS, candidal infections
can occur throughout the entire body and can be life-threatening. The blood,
brain, eye, kidney, and heart are most frequently affected, but the candidal
fungus also can grow in the lungs, liver, and spleen. Candida is the
leading cause of esophagitis (inflammation in the throat) in people with AIDS
What are the symptoms of candidiasis?
The symptoms of candidiasis vary depending on the location of the infection.
The following are the most common symptoms of a yeast infection. However, each
individual may experience symptoms differently. Symptoms may include:

The symptoms of candidiasis may resemble other skin conditions. Always
consult your physician for a diagnosis.
How is candidiasis diagnosed?
In addition to a medical history and physical examination, your physician may
scrape off a skin sample to confirm the diagnosis with a microscope or a
culture.
For the microscope method, a scraping or swab of the affected area is placed
on a microscope slide. A single drop of 10% potassium hydroxide (KOH) solution
is then also placed on the slide. The KOH dissolves the skin cells but leaves
the Candida untouched, so that when the slide is viewed under a microscope, the
hyphae and pseudo spores of Candida are visible. Their presence in large
numbers strongly suggests a yeast infection.
For the culturing method, a sterile swab is rubbed on the infected skin
surface. The swab is then rubbed across a culture medium. The medium is
incubated for several days, during which time colonies of yeast and/or bacteria
develop. The characteristics of the colonies provide a presumptive diagnosis of
the organism causing symptoms.
The effect on your fertility
Although candidiasis will probably not affect your
fertility, it is important to clear up any infection during
pregnancy, as your
baby may catch the infection from the birth canal during delivery. A baby born
with candidiasis can develop diaper rash and a sore mouth, which may lead to
feeding difficulties. Thrush is very common in pregnancy (affecting about one in
four women) because a pregnant woman�s vaginal secretions favor the growth of
yeast. Men may get soreness or itching of the penis from candida but are often
not affected. As candida is not sexually transmitted, your partner will only
need treatment if you are having problems with recurrent thrush or if he has
discomfort.
Treatment and Care
Specific treatment for candidiasis will be determined by your physician based
on:
-
your age, overall health, and medical
history
-
extent of the condition
-
your tolerance for specific
medications, procedures, or therapies
-
expectations for the course of the
condition
-
your opinion or preference
Modern antifungal treatments are usually very effective at curing an
attack of thrush. Most antifungals, such as clotrimazole, can be given as a
vaginal suppository and are safe during the preconception period. New oral antifungals
are now available, but these are often not necessary, and as a rule
they should be avoided in pregnancy because they have not been proven to be safe
for the baby. An antifungal cream may help your symptoms for a few days but it
will not get rid of the large reservoir of yeast present in the vagina.
Lactobacillus is present in live yogurt, so for immediate treatment, try soaking
a tampon in live yogurt and inserting one into your vagina twice a day for a few
days. An experiment showed that women who ate 8 ounces (225 gm) of live yogurt a
day reduced their risk of getting the
infection by two-thirds.
Garlic has also been shown to help prevent thrush in babies and women. It can be
inserted into the vagina of a woman, although it may be more effective if taken
orally. You can take garlic capsules or eat it fresh, but capsules are less
odorous! Allicin is the active ingredient and is also present in onions.
Candida likes a moist, warm place to grow so avoid wearing tight jeans,
synthetic underwear, or panty liners unnecessarily. It also grows well in damaged
skin so it�s best to refrain from using perfumed soap, bubble bath, vaginal
deodorant, and douches.
You should also try to limit your intake of very sweet foods and drinks,
including alcohol.
