What is a yeast infection?

Yeast infection is caused by a type of fungus (yeast) called candida. Small numbers of candida normally live on your skin and do no harm. Sometimes, under certain conditions, they can multiply. This causes a yeast infection. The common sites for candida to cause infection are your vagina (vaginal thrush), your mouth (oral thrush) and your skin. This leaflet just deals with yeast infections (candidal skin infections). See the separate leaflets called Vaginale Pilzinfektion und Oral thrush (Yeast infection) für weitere Details.

Yeast infection symptoms

The main symptoms of a yeast infection include:

• Redness and swelling in affected folds of the skin (under breasts, groin etc).

• A sore and itchy rash my develop.

• Small blister-like swellings may develop on the rash.

• White-yellow, cottage cheese-like substance over the affected area.

• If affected area is in between the toes or fingers, skin may become thickened, white and soft.

What causes a yeast infection?

The chance of the candida yeast overgrowing and a yeast infection developing on the skin is more likely in the following situations:

• Areas of skin that are moist or sweaty are ideal for candida to thrive. Therefore, the common sites affected by yeast infections are in the folds of skin in your groin, armpits and under large breasts. (Another name for inflammation within a fold of skin or under a breast is 'intertrigo'. Candidal infection is a common cause of intertrigo.) Nappy rash is sometimes due to yeast infections . Obese people may develop candidal infection between folds of skin. It can also affect skin between your fingers and toes and at the corners of your mouth.

• Wenn Sie Diabetes (Diabetes mellitus).

• If you take a long course of Antibiotika oder Steroidmedikation.

• If you have a schwaches Immunsystem (Immunsuppression). For example, if you have AIDS, or have Chemotherapie, or have certain types of serious blood disorder.

Is a yeast infection serious?

Usually not. Most yeast infections occur in people who are otherwise healthy (although they are more common in women, or if you are overweight). Treatment usually works extremely well. In some people, the yeast infection may be the first indication of another condition such as diabetes (Diabetes mellitus).

Wann man einen Arzt aufsuchen sollte

If you suspect a yeast infection but are unsure, you should see a doctor to confirm the diagnosis.

If you have a rash that you know is a yeast infection and you are happy to buy over the counter treatment, you can self treat. If the rash fails to improve after 2 weeks of treatment it is sensible to discuss it with your doctor.

Some people with a yeast infection can develop an added infection caused by another type of germ (bacterium). It is important to see your doctor if your skin infection does not improve or if it worsens, as you may need an alternative treatment for a bacterial infection. This is usually a different cream containing an antibiotic, such as Fusidinsäure. Occasionally antibiotic tablets or medicine may be needed.

It is also sensible to see a clinician if you become unwell in yourself.

How to get rid of a yeast infection

Ein antimykotische Creme usually clears the infection within a week or two. Yeast infection creams commonly used include:

• Clotrimazole.

• Econazole.

• Miconazole.

• Ketoconazole (in adults only, not suitable for use in children).

• Terbinafin.

Sometimes a mild steroid cream is added to reduce inflammation and itch whilst the antifungal cream is working. The most commonly added steroid cream is hydrocortisone. These combination creams are easier to use. A steroid cream should not be used on its own for a fungal skin infection.

Occasionally, if your yeast infection rash is widespread, antifungal tablets called Fluconazol are prescribed. These are usually taken once a day for two weeks.

Can Sudocrem® help with a yeast infection?

Protection of the area with a barrier cream (Bepanthen®, Sudocrem®) is often highly recommended as a first defence.

Your doctor may recommend that you wash your skin with a moisturising cream or ointment (emollient) which is more sensitive on your skin than soap products. Certain emollients are useful as soap substitutes in this situation.

Can yeast infections be prevented?

To minimise the risk of a yeast infection:

• Keep areas likely to be affected as clean and dry as possible.

• Always dry well after washing, particularly in your groin, armpits and under large breasts. Some people use a hair dryer to dry these areas after washing to ensure they are dry before putting clothes on.

• Wear light, loose, absorbent clothing and avoid wool and synthetic fibres. This helps to keep your skin from becoming too moist.

• Obesity is a risk factor for yeast infection so losing weight may help.

• Avoid anything wet being in contact with the skin for very long. So, change nappies or incontinence pads as soon as they are wet. If you have been exercising and are in wet, sweaty clothes, change into dry clothes as soon as you can.

• If you are troubled with repeated infections at the angle of your mouth and you wear dentures:

  • Remove the dentures each night to clean them.

  • Sterilise the dentures overnight.

If the infection keeps coming back for no apparent reason, a test to check for Diabetes (diabetes mellitus) may be advised by a doctor.
