Yeast infections, also known as candidiasis, can occur in the nails, skin, and mucous membranes throughout the body. Candida, a naturally occurring yeast-like fungus, is present in every human body. However, in certain conditions, Candida can multiply out of control, leading to yeast infections. Yeast onychomycosis, often caused by Candida, affects the fingernails more commonly than toenails. It is characterized by nail thickening, discoloration, and fragility, with the nail sometimes separating from the nail bed. Treatment options include topical and oral antifungal medications, with oral treatments being more effective in penetrating the nail.

What You'll Learn
Candida is a common cause
Candida is a naturally occurring fungus present in the human body. It is usually harmless, but certain conditions can cause it to multiply and lead to a yeast infection known as candidiasis, which often affects the skin or nails. Candida is the most common cause of yeast infections, with 20 types, including Candida albicans, capable of causing infections in humans.
Candida yeast infections can develop in folds of the skin and areas with moisture and warmth, such as the feet. This is why it is important to keep the skin and nails dry and clean, especially after sweating or being in water. Candida infections can occur slowly, and symptoms include nail discolouration, detachment, abnormal shaping, and unusual texture. The nail may become thick, fragile, and easy to break, and the skin around it may become painful and swollen.
Yeast onychomycosis, often caused by Candida, is a type of mycotic nail infection that affects the fingernails more than the toenails. It is a sign of a weakened immune system and can be treated with antifungal medications. Topical treatments are less effective, and oral medications are often required for up to 12 weeks for toenail infections.
Paronychia is another type of nail infection caused by the yeast-like organism Candida. It is commonly caused by injury to the nail area, such as biting or picking at the hangnail or cuticle. Paronychia causes inflammation, redness, and swelling around the nail, and nail changes may also occur. Treatment for paronychia often involves antifungal medication, but proper nail care and hygiene are essential to prevent yeast infections.

Signs and symptoms
A fungal nail infection, also known as onychomycosis or tinea unguium, is caused by an overgrowth of fungi in, under, or on the nail. While yeast is a less common cause of nail infections, it can cause an infection around the nail, known as paronychia, or an infection of the nail itself, known as yeast onychomycosis.
Yeast onychomycosis is characterised by swollen and inflamed areas around the nails, which may become entirely detached. Nails may also become discoloured (yellow, white, brown, or black), thick, and fragile. The area around the nails may also exhibit signs of injury, such as biting off or picking a hangnail, or from trimming or pushing back the cuticle.
Paronychia caused by yeast-like organisms such as Candida presents as a painful, red, swollen area at the base of the nail. There may also be pus-filled blisters, and the nail may appear detached, abnormally shaped, or discoloured.
Fungal nail infections can be challenging to identify in their early stages, as they often start mildly and progress to more severe symptoms. Toenails are more commonly affected than fingernails due to the warm, moist environment created by shoes. Additionally, the reduced blood flow to the toes compared to the fingers makes it harder for the body to detect and prevent infections.
If left untreated, fungal nail infections can cause pain and discomfort, making it difficult to walk or apply pressure to the affected area.

Prevention and treatment
Candida is a fungus that is present in every human body. Sometimes, this fungus can overgrow in moist areas of the skin, leading to an infection known as candidiasis, which can affect the skin and nails. This infection is not usually painful, but if left untreated, it may lead to discomfort when wearing shoes.
Preventing yeast infections on the nails
- Keep the skin and nails dry and clean.
- Change out of sweaty or wet clothing, wash with soap, and dry thoroughly.
- Wear flip-flops in public pools and showers to avoid the growth and spread of yeast.
- Choose reputable beauty salons with established hygiene standards.
- Avoid biting or picking your nails.
- Protect your nails from exposure to detergents and chemicals by wearing rubber or plastic gloves.
- Bring your own manicure tools to nail salons.
- Trim your nails regularly, especially after bathing when they are softer.
- Smooth the edges of your nails with an emery board.
- Keep your nails away from harsh substances or water by wearing gloves.
Treating yeast infections on the nails
- Topical antifungal medications are usually prescribed for yeast infections. However, some cases may require long-term oral medication.
- If an underlying condition is causing the infection, such as an antibody deficiency, specific treatment for that condition may be necessary.
- Strengthen your nails with petroleum jelly or thicker-based lubricants instead of watery lotions.
- If you have diabetes or a weakened immune system, seek medical advice if you develop symptoms of candidiasis.

Risk factors
While yeast infections can occur on the skin and nails, they are more likely to affect the fingernails. This type of infection is called yeast onychomycosis and is caused by the yeast-like organism Candida. Candida is a naturally occurring fungus on the body, but certain factors can cause it to multiply and lead to an infection.
Yeast infections on the nails are often the result of a weakened immune system. This can be due to immunodeficiency problems, which can have genetic causes. Health conditions such as diabetes and hormonal conditions, including thyroid problems, Addison's disease, and Cushing's disease, can also affect the immune system and increase the risk of yeast infections.
Injury to the nail area, such as biting or picking at hangnails, or trimming and pushing back the cuticle, can create an entry point for yeast to enter and cause an infection. It is important to avoid damaging the nails or fingertips and to keep the nails dry and clean. Wearing gloves can help protect the nails from exposure to detergents and chemicals.
Fungal infections, such as athlete's foot, can also increase the risk of a yeast infection on the nails. Additionally, blood circulation problems and nail surgeries may make individuals more susceptible to yeast infections in the nails.
Yeast thrives in warm and humid environments, so keeping the skin and nails dry can help reduce the risk of infection. Wearing flip-flops in public pools and showers can help prevent the spread of fungal infections.

Diagnosis
Yeast infections on the nails, or mycotic nails, are caused by yeast onychomycosis, which is often caused by Candida. Candida is a naturally occurring yeast on the skin and mucous membranes of the body. However, certain factors can cause it to multiply out of control, leading to an infection.
Mycotic nails are fungal infections that affect the toenails or fingernails, causing the nail to separate from the nail bed and become thick, discoloured, and fragile. The discolouration can appear as white, yellow, brown, or black. While mycotic nails are not a serious condition, they can take a long time to treat.
If you suspect a yeast infection on your nails, it is recommended that you see a healthcare provider for a diagnosis and treatment. Your doctor will likely ask about your medical history and examine any symptoms. They may also take a nail sample or perform a skin scrape to test for the type of infection. In some cases, a blood test may be necessary to check the proper functioning of the liver before and during treatment.
Before starting treatment, it is important to accurately diagnose the type of nail fungus you have. Your healthcare provider can help identify the specific type of nail fungus causing the infection. Additionally, it is recommended to refrain from clipping or trimming your nails, as this can spread the infection.
To prevent yeast infections on the nails, it is crucial to maintain proper nail care and hygiene. This includes keeping the nails and skin clean and dry, avoiding damage to the nails or cuticles, and taking precautions when visiting nail salons, such as bringing your own manicure tools and avoiding cuticle trimming.

Frequently asked questions
A yeast nail infection is a type of fungal infection that occurs when yeast enters a crack in the nail or the skin around it. Yeast infections are caused by an overgrowth of a fungus called Candida, which is naturally present on the skin and mucous membranes.
Symptoms of a yeast nail infection include swelling and inflammation around the nail, discolouration (white, yellow, brown or black spots), thickening of the nail, and detachment of the nail from the nail bed. In some cases, the nail may come off entirely.
Yeast nail infections occur when Candida grows out of control due to certain factors such as a weakened immune system, diabetes, hormonal conditions, or injury to the nail. Toenails are more susceptible than fingernails because yeast thrives in dark, warm places, and there is less blood flow in the toes, making it harder for the body to detect and prevent the infection.
Yeast nail infections can be treated with topical antifungal medications, oral medication, or, in severe cases, surgical removal of the nail. To prevent yeast nail infections, it is important to keep the skin and nails clean and dry, practice good hygiene, and avoid damaging the nails or cuticles.
