Yeast infections are fungal infections primarily caused by an overgrowth of Candida, a type of yeast naturally found in the body.
Common areas affected are the mouth, throat, gut, and genitals. Symptoms like itching, redness, and discharge vary depending on the infection type. Risk factors include antibiotic use, hormonal changes, and weakened immune systems. Treatments range from OTC medications to prescription drugs, with preventive measures like probiotics and proper hygiene helping to reduce occurrences.
Learn more about the types, symptoms, and causes of yeast infections and how to effectively manage and prevent them.
What is Candida?
Candida is a genus of yeast that naturally resides in various parts of the human body, such as the skin, mouth, throat, gut, and genital area. In its balanced state, Candida coexists harmlessly with other microorganisms. However, when the natural balance of these microorganisms is disrupted, Candida can overgrow, leading to a yeast infection.
Role of Candida in the Body
Candida plays a significant role in our body. It is typically harmless and can even be beneficial, helping to control harmful microorganisms through competition for nutrients and space. However, certain conditions can cause an overgrowth of Candida, transforming it from a benign organism into a pathogen.
Common Candida Species
There are several types of Candida species, but the most common one associated with yeast infections is Candida albicans (source). This species is responsible for the majority of yeast infections. Other species like Candida glabrata and Candida tropicalis can also cause infections but are less prevalent. It’s important to understand which type of Candida is causing the infection to ensure appropriate treatment.
Common Types of Yeast Infections
Yeast infections can occur in different parts of the body, each presenting unique symptoms and requiring specific treatments. The most prevalent types include vaginal yeast infections, oral thrush, and cutaneous candidiasis.
Vaginal Yeast Infections
About 75% of women and people assigned female at birth (AFAB) experience vaginal yeast infections at some point in their lives. Symptoms commonly include:
- Itching and irritation: persistent itchiness around the vaginal area.
- Burning sensation: discomfort during urination or sexual intercourse.
- Discharge: a thick, white, odorless discharge resembling cottage cheese (source).
Oral Thrush
Oral thrush, or oral candidiasis, often affects babies, older adults, and people with weakened immune systems. Notable symptoms are:
- White patches: appearing on the tongue and inner cheeks (source).
- Soreness: which can make eating and swallowing painful.
- Cotton-like feeling: resulting in general mouth discomfort.
Cutaneous Candidiasis
Cutaneous candidiasis occurs on the skin, particularly in warm, moist areas such as the armpits and groin. Key symptoms include:
- Red rashes: marked with itching and irritation.
- Pustules: accompanied by cracking in severe cases.
Understanding the types of yeast infections can help you identify symptoms early, leading to more effective management.
Symptoms of Yeast Infections
Recognizing the symptoms of yeast infections early can make it easier to seek and receive timely treatment. Below, we break down the symptoms according to the type of infection.
Vaginal Yeast Infections
Vaginal yeast infections can cause a variety of symptoms. Common symptoms include:
- Intense vaginal itching and burning.
- A thick, white discharge that does not have a bad odor.
- Redness and swelling of the vulva.
- Pain during intercourse or urination (source).
Oral Thrush
Oral thrush presents differently than vaginal infections. Its symptoms include:
- White, creamy lesions on the tongue or inner cheeks.
- Redness and soreness, potentially leading to difficulties eating or swallowing.
- Cracking and redness at the corners of the mouth.
Cutaneous Candidiasis
Cutaneous candidiasis affects the skin and can appear in any area but typically targets moist environments. Symptoms can involve:
- Red, itchy rashes, sometimes with pustules.
- Rash spreading in a horseshoe or satellite pattern.
- Cracks or sores in affected areas.
Recognizing these symptoms can prompt you to take the appropriate steps for treatment and relief.
Causes and Risk Factors
Various factors can lead to a yeast infection, each influencing the body’s balance of microorganisms and allowing Candida to overgrow.
Antibiotic Use
Antibiotics aimed at treating bacterial infections can disrupt the balance of natural flora in your body, causing a decrease in lactobacilli, beneficial bacteria that keep Candida levels in check. Without enough of these bacteria, Candida can proliferate, leading to an infection.
Hormonal Changes
Fluctuations in estrogen levels, often due to pregnancy, hormonal contraceptives, or hormone replacement therapy, can increase the risk of yeast infections. Higher levels of estrogen create an environment conducive to Candida growth.
Weakened Immune System
Individuals with compromised immune systems are particularly susceptible to yeast infections. Conditions such as HIV/AIDS, cancer treatments, or the use of immunosuppressive drugs can lower the body’s ability to fight off the overgrowth of Candida (source).
Lifestyle Factors
Certain lifestyle habits can also increase your risk:
- High-sugar diet: Candida thrives on sugar, so consuming large amounts can fuel its growth.
- Stress: High-stress levels can weaken the immune system.
- Wearing tight or non-breathable clothing: This creates a warm, moist environment that Candida loves.
Underlying Health Conditions
Health conditions such as diabetes can make you more susceptible to yeast infections. High blood sugar levels facilitate the growth of Candida (source).
Identifying these causes and risk factors can help you take preventive measures to reduce the likelihood of a yeast infection. For more tailored advice and resources, visit Feminine Health.

Diagnosis of Yeast Infections
Diagnosing yeast infections involves several steps to accurately identify the underlying cause, ensuring proper treatment. Here’s what you can expect during the diagnostic process.
Medical History Review
During your visit, the healthcare provider will start by reviewing your medical history. They will ask questions about your symptoms, onset, frequency, and any previous yeast infections or treatments. This helps narrow down potential triggers and risk factors contributing to the infection.
Physical Examination
For vaginal yeast infections, a pelvic exam is usually performed. During this exam, the healthcare provider will inspect the vulva and vagina for signs of infection. Similarly, an oral examination is conducted to check for white patches and redness indicative of oral thrush.
Laboratory Tests
The cornerstone of diagnosis is laboratory testing. The healthcare provider will take a sample from the affected area (e.g., a vaginal swab or oral smear) to examine under a microscope. This can confirm the presence of Candida and help identify the specific species causing the infection.
Advanced diagnostic tools like PCR (Polymerase Chain Reaction) tests and β-d-glucan assays are sometimes utilized to detect Candida at a molecular level, offering greater accuracy and faster results. These tests can be particularly useful for persistent or recurrent infections (source).
Vaginal pH Test
For vaginal yeast infections, a vaginal pH test may be done. This test helps differentiate between bacterial infections and yeast infections. While bacterial infections tend to raise vaginal pH, yeast infections generally do not alter it significantly, providing additional diagnostic clarity.
Treatment Options
Treating yeast infections effectively requires choosing the right strategy based on the type and severity of the infection. Here are the most common treatment options available.
Over-the-Counter Medications
If you have a mild yeast infection, over-the-counter antifungal medications, such as clotrimazole (Monistat) and miconazole (Vagistat-1), can be effective. These treatments are available as creams, ointments, or suppositories and typically resolve symptoms within 1 to 7 days (source).
Pros:
- Readily available without a prescription.
- Various forms allow for personalized treatment.
Cons:
- May cause mild side effects like burning or irritation.
Prescription Medications
For more severe or persistent infections, prescription antifungal medications like fluconazole (Diflucan) are often recommended. This oral medication is typically taken as a single dose and offers quick relief within 1 to 3 days.
Pros:
- Highly effective and convenient (one-dose treatment).
- Suitable for more complex infections.
Cons:
- Potential side effects include gastrointestinal issues and liver concerns.
Home Remedies
Some individuals opt for natural remedies to treat yeast infections. Probiotics, apple cider vinegar, and tea tree oil are among the most commonly used home treatments. While these can be beneficial, exercise caution and consult healthcare advice to ensure safety and efficacy.
Pros:
- Can be more affordable and holistic.
- Probiotics may offer additional gut health benefits.
Cons:
- Efficacy varies and may not be supported by strong scientific evidence.
- Potential for allergic reactions.
