Veröffentlicht 2024-02-05 12:23:00

Candidiasis, also known as thrush or yeast infection, is a fungal infection caused by the yeast Candida. It is one of the more common infections affecting people today. In this article, we will take an in-depth look at candidiasis - what causes it, symptoms, diagnosis and various treatment options available.

What is Candidiasis?

Candidiasis refers to any infection caused by yeasts of the genus Candida. There are over 20 Candida species that can cause infection in humans, with Candida albicans being the most common. Candida normally lives on the skin and inside the mouth, intestine and areas like the vagina in small numbers without causing any problem. However, if conditions become favourable, the yeast can overgrow and cause infection.

Types of Candidiasis

There are different types of candidiasis depending on the area affected:

Oral Candidiasis: Also known as thrush, it causes white patches or coating in the mouth or throat. Thrush is common in babies and the elderly.

Vulvovaginal Candidiasis: It affects the vagina and vulva, commonly known as a vaginal yeast infection with symptoms like itching and discharge. This is one of the most common types especially in women.

Cutaneous Candidiasis: Candida can infect the skin, especially moist areas like under the breasts or between fingers, causing rashes or blisters.

Esophageal Candidiasis: This affects the esophagus or food pipe, causing problems swallowing. It is commonly seen in HIV/AIDS patients.

Systemic Candidiasis: Serious invasive Candida infections that spread throughout the body affecting blood, heart, eyes or other parts. These are life-threatening and occur mainly in those with weakened immunity.

Causes and Risk Factors

Some of the major causes and risk factors for candidiasis include:

- Antibiotic use which disrupts the normal balance of microbes.

- Poor immune system in conditions like HIV/AIDS, diabetes or cancer therapy patients.

- Moist warm areas like skin folds are ideal for Candida overgrowth.

- Hormonal changes during pregnancy or periods favor Candida growth.

- Medical devices like dentures, IV lines providing entry points.

- Underlying disease like diabetes favors candidiasis as Candida thrives in high sugar environment.

Symptoms

Symptoms vary depending on the type of candidiasis but common ones are:

- Oral Thrush: White patches or coating on tongue or inner cheeks with redness.

- Vaginal infection: Thick, white vaginal discharge without obvious odor along with itching and irritation.

- Cutaneous infection: Raised red irritated patches of skin that may crack or scale over.

- Esophageal infection: Burning or pain while swallowing, inability to swallow.

Diagnosis and Treatment

A doctor will look for symptoms and examine the affected area. Samples may sometimes be collected and examined under the microscope to confirm the presence of Candida. Based on the type and severity, treatment options include:

- Topical antifungal medications like creams or ointments for skin or vaginal infections.

- Oral medications like fluconazole, itraconazole for more severe cases. Multiple doses may be required to cure deep infections.

- For esophageal infection, oral antifungal medications and endoscopy to examine internal damage may be required.

- Treatment duration depends on case but usually 7-14 days is common.

Prevention is Key

Proper hygiene and taking steps to avoid overgrowth is the key to prevention:

- Keep skin dry particularly in moist areas.

- Wear loose cotton underwear.

- Use antimycotic powders in skin folds as needed.

- Use condoms during vaginal intercourse if partner has candidiasis.

- Good control of conditions like diabetes and proper use of antibiotics as directed.

- Reduce sugar intake and don't take medications without doctor's advice.

- Get immediate treatment if symptoms develop to avoid further complications.

In conclusion, candidiasis is a common fungal infection that needs to be properly diagnosed and treated. Minor changes in lifestyle and hygiene can go a long way in preventing overgrowth of Candida and worsening of symptoms. With the growing public health concerns of antibiotic resistance, candidiasis is likely to remain an ongoing challenge. However, awareness and timely medical care ensures most affected individuals make a full recovery.
