What You Need to Know About Yeast Infection

What is Yeast and What Causes It?

  • Yeast vaginitis is the second most common vaginal infection after bacterial vaginosis
  • 75% of women experience an episode of vaginal yeast infection at some time in their life
  • Yeast infections are caused by fungal organisms.
  • The majority of vaginal yeast infections are caused by Candida Albicans
  • There are some less common yeast organisms such as Torulopsis Glabrata that may cause infections that do not clear up with the usual therapies
  • Yeast infections may be more common in women who have taken antibiotics, are on hormonal contraception, have diabetes and or are pregnant.
  • Women who have medical conditions or take medicines which weaken the immune system are at greater risk for yeast

Signs and Symptoms of Yeast Vaginitis

  • Yeast infections may cause no symptoms
  • Sometimes yeast is noted on a Pap test and does not require treatment, unless there are symptoms
  • There may be increased vaginal discharge with yeast infection
  • This is typically described as thick or curdy
  • There may be mild to moderate itching and irritation
  • If the genital skin becomes very irritated, it may become red, swollen and may develop splits.

How is yeast diagnosed?

  • The symptoms of thick curdy discharge, itch and irritation are classic for yeast
  • Recent antibiotic use or steroids may suggest the possibility of yeast
  • The health care provider will perform a vaginal exam and observe the genital skin
  • The acid base level of the vagina is generally normal
  • Samples of vaginal discharge may be taken with a swab
  • The sample will be evaluated under the microscope for the presence of yeast
  • Even when yeast is present, it is only seen under the microscope half the time
  • Seeing yeast under the microscope confirms the diagnosis, but if yeast is not seen, the infection may be treated based on the symptoms. In some cases, a culture may be sent to the laboratory by swabbing the vagina and placing it in a culture tube.
  • The culture is more accurate than the information that is obtained under the microscope and takes a few days to get the results
  • A culture is used when a woman has a complicated problem such as failure to clear her infection or repeated infections.

Treatment of Yeast Vaginitis

  • Over the counter medications can be obtained without a prescription
  • These include creams for the external genital skin, suppositories and creams for the vagina that are inserted with an applicator
  • Caution should be used when self-treating for yeast. Women who have been previously diagnosed for yeast and develop similar signs and symptoms may consider choosing to obtain over the counter treatments
  • If a woman does not improve, she should seek the advice of a health care provider.
  • Women who have frequent yeast infections may need to be treated for longer than the usual length of time
  • If you have frequent yeast infections you may want to discuss longer treatment with your practitioner
  • If you are pregnant, you should be sure to consult with a health care practitioner

I started the Inconvenient Woman Blog in 2007, and am the product of a long line of inconvenient women. The matriarchal line is French-Canadian, Roman Catholic, with a very feisty Irish great-grandmother thrown in for sheer bloody mindedness. I am a research analyst and author who has made her living studying technical data, and developing articles, training materials, books and web content. Tracking through statistical data, and oblique cross-references to find the relevant connections that identifies a problem, or explains a path of action, is my passion. I love clearly delineating the magic questions of knowledge: Who, What, Why, When, Where and for How Much, Paid to Whom. My life lessons: listen carefully, question with boldness, and personally verify the answers. I look at America through the appreciative eyes of an immigrant, and an amateur historian; the popular and political culture is a ceaseless fascination. I have no impressive initials after my name. I’m merely an observer and a chronicler, an inconvenient woman who asks questions, and sometimes encourages others to look at things differently.
