What does a fungal infection look like

What you need to know about fungal infections

The following conditions are all common types of fungal infections.

Athletes foot

Tinea pedis or athletes foot is a common fungal infection that affects the foot.

Athletes foot is commonly associated with sports and athletes because the fungus grows perfectly in warm, moist environments, such as socks and shoes, sports equipment, and locker rooms.

In reality, anyone may be affected by athletes foot. It is most common in warmer climates and summer months, where it can quickly multiply.

Symptoms

Athletes foot is a common infection where the fungus grows in warm and moist environments.

The symptoms of athletes foot may vary slightly from person to person and can look red on lighter skin tones but appear dark brown on darker skin tones. Classic symptoms include:

• discoloration and blisters on the affected area
• the infected skin may be soft, or layers may start to break down
• peeling or cracking skin
• the skin may scale and peel away
• itching, stinging, or burning sensations in the infected area

Diagnosis, treatment, and prevention

Not all itchy feet are the result athletes foot. Doctors usually diagnose the infection by scraping scaling skin off of a person and inspecting it under a microscope for evidence of any fungus.

There are a few different fungi that can cause athletes foot. The infection may behave differently depending on the specific fungus that is infecting the skin.

Athletes foot is often treated with topical antifungal ointments, which are available to purchase over-the-counter or online. Severe infections can require additional oral medications as well. The feet will also need to be cared for and kept dry to help kill the fungus.

Prevention methods include allowing the feet plenty of air to breathe and keeping them clean and dry. It is a good idea to wear sandals in public showers or locker rooms.

Yeast infection

Vaginal yeast infections are a common form ofCandida overgrowth in women, usually caused by Candida albicans.

An overgrowth of Candida disrupts the normal balance of the bacteria and yeast in the vagina. This imbalance of bacteria may be due to antibiotics, stress, hormone imbalances, or poor eating habits, among other things.

Candida infections can also commonly cause fungal toenail infections and diaper rash.

SymptomsA yeast infection may commonly cause fungal toenail infections.

Symptoms of a yeast infection include:

• itching and swelling around the vagina
• burning sensations or pain during urination or intercourse
• redness and soreness on and surrounding the vagina
• unusual vaginal discharge, such as gray clumps that resemble cottage cheese or a very watery discharge

A rash may develop over time in some cases. Yeast infections should be treated quickly, as the symptoms may become severe if left untreated.

Diagnosis, treatment, and prevention

The classic symptoms of a yeast infection make them easy to diagnose. Doctors may ask about the persons medical history, such as any previous yeast infections or sexually transmitted infections (STIs). They may also ask whether the person was recently taking antibiotics.

Doctors will then examine the vaginal walls and cervix for signs of infection, taking cells from the vagina if necessary for proper diagnosis.

Treatment of yeast infections depends on their severity. Standard treatments include creams, tablets, or suppositories, which are available via prescription, over-the-counter, or online. Complicated infections may require complex treatments.

Avoiding yeast infections begins with a balanced diet and proper hygiene. Wearing loose-fitting clothing made from natural fibers may also help prevent infection. Washing underwear in very hot water and changing feminine products often can also help prevent fungal growth.

Jock itch

Tinea cruris, commonly known as jock itch, is another common fungal skin infection.

These fungi love warm and damp environments and thrive in moist areas of the body, such as the groin, buttocks, and inner thighs. Jock itch may be more common in summer or in warm, humid areas of the world.

Jock itch is mildly contagious and is often spread through direct contact with an infected person or an object that is carrying the fungus.

SymptomsThrush can affect the genital area in men as well as women.

Jock itch appears on the body as an itchy, rash that often has a circular shape to it. Symptoms include:

• groin, buttocks, or thighs can be red, flaky, or scaly, and on darker skin, the rash may appear gray or brown
• chafing, irritation, itching, or burning in the infected area
• a rash with a circular shape and raised edges
• cracking, flaking, or dry peeling of the skin in the infected area

Diagnosis, treatment, and prevention

Jock itch has a very particular look and can usually be identified based on its appearance. If doctors are uncertain, they may take a skin sample to inspect and confirm their diagnosis.

Treating jock itch usually involves topical antifungal ointments and proper hygiene. Many cases of jock itch are improved by over-the-counter medications, though some require prescription medications. Cleaning the affected area and keeping it dry can also help kill the fungus.

Jock itch can be prevented by wearing loose-fitting natural fibers, such as cotton underwear which is available to buy online. Avoiding contact with others who have the infection is also important. Avoiding shared items, such as towels and sporting equipment may also help.

Ringworm

Tinea corporis or ringworm is a skin infection caused by a fungus that lives on dead tissues, such as the skin, hair, and nails. Ringworm is a fungus that causes both jock itch and athletes foot. When it appears anywhere else on the body, the infection is just called ringworm.

Symptoms

Ringworm is a skin infection that causes jock itch and athletes foot.

Ringworm is usually easy to notice because of its shape. A patch that may itch or be scaly will often turn into a raised, ring-shaped patch of skin over time. It may even spread out into several rings.

The outside of this ring may appear red on light skin and gray or brown on skin of color, and may also appear raised or bumpy, while the inside of the ring will appear clear and healthy and the edges of the ring may spread outward.

Ringworm is highly contagious, and it can be transmitted by skin-to-skin contact, or from contact with pets, such as dogs. The fungus may also survive on objects, such as towels, clothes, and brushes.

The ringworm fungus also infects soil and mud, so people who play or work in infected dirt may catch ringworm as well.

Diagnosis, treatment, and prevention

Other skin conditions may look like ringworm, so doctors will sometimes want to take a skin sample to inspect for the fungus.

After confirming a diagnosis, doctors will recommend a treatment, depending on how severe the symptoms are.

Creams and medicated ointments are often sufficient to treat many cases of ringworm and may be purchased over-the-counter or online. Ringworm of the scalp or severe ringworm may require a prescription.

Basic hygiene can help treat and prevent ringworm as well. Keeping the skin clean and dry can help avoid infection.

Safety in public includes wearing sandals into public showers or locker rooms and avoiding shared items and towels.

What does a yeast infection look like?

The appearance of a yeast infection, or candidiasis, depends on its location. It can cause white patches in the mouth, flaking or crusting of the skin, and changes in genital discharge, which may look like cottage cheese.

In this article, we describe how a yeast infection visibly affects the body. We also look at other symptoms, treatments, and more.

A yeast infection occurs when fungi grow excessively in the body. This is particularly common in moist areas with less exposure, such as the mouth, vagina, or feet.

Often, yeast infections are caused by fungi from the Candida species and according to the Centers for Disease Control and Prevention (CDC), Candida albicans is the type most likely to overgrow and cause an infection.

A vaginal yeast infection, or thrush, typically causes white discharge that is the texture of cottage cheese. Other symptoms of a vaginal yeast infection include:

• painful urination
• soreness around the vagina
• inflammation and itchiness of the vagina and vulva
• pain during sex

These infections are common, with up to 75% of females having at least one diagnosed in their lifetimes.

Yeast infections can affect the penis, but this is less common. The symptoms tend to develop on the underside of the penis and include:

• scaling
• inflamed patches of skin
• a painful rash

A yeast infection can also cause inflammation near the head of the penis. This issue is called balanitis. A person with balanitis may experience burning or itching and yellow or white discharge. In some people, the inflammation spreads to the shaft and the area under the foreskin.

Yeast infections are not considered sexually transmitted infections (STIs). However, it is possible for a person to develop a yeast infection after having oral, anal, or vaginal sex with someone who has the condition, especially if they are especially susceptible.

Around 15% of males who have unprotected sex with females experiencing yeast infections develop the infection themselves.

Oral thrush occurs when yeast grows excessively in the mouth or throat. Typically, a person develops white patches on the tongue, cheeks, back of the throat, or roof of the mouth.

Other symptoms of oral thrush include:

• soreness
• pain while eating or drinking
• a cotton-like feeling in the mouth
• cracked skin at the corners of the mouth
• a loss of taste

Most healthy adults do not develop oral thrush, but yeast infections in the mouth or esophagus are common in people with weakened immune systems.

Wearing dentures, smoking, and having dry mouth also elevate the risk of developing oral thrush.

The appearance of a yeast infection on the skin depends on the location, but this type of infection often causes patches of inflammation. These can vary in shape and size.

Sometimes, these patches itch, flake, or develop crusts, and pustules may appear around the edges.

A yeast infection can occur anywhere on the skin, but is most likely to develop in folds, such as:

• under the breasts
• under the arms
• in the groin
• under or in the buttocks
• in the navel
• on the scalp
• between the fingers and toes

If a yeast infection occurs on the scalp, it can cause crusty lesions that can lead to hair loss. Yeast infections can also cause diaper rash in babies.

Yeast infections can develop beneath the nails. An infected nail may turn white or yellow and start to separate from the nail bed.

When a yeast infection occurs under the nails, a person may experience:

In small amounts, Candida fungi are not harmful. Many people have yeast on their skin and in their body. Other types of microbe, such as bacteria, help keep Candida from growing excessively.

However, certain factors can disrupt the bodys ability to keep Candida under control, such as:

• Antibiotics: Because antibiotics kill bacteria, the result may be that Candida fungi grow unchecked.
• Hormonal contraceptives: People who take hormonal birth control that contains estrogen are more likely to develop yeast infections.
• Pregnancy: Similarly, the hormonal changes during pregnancy increase the chances of developing yeast infections.
• A weak immune system: Young babies and people with immune disorders or conditions such as HIV may be more susceptible to yeast infections.
• Medications: Some medications and treatments, including steroids, immunosuppressants, and chemotherapy also weaken the immune system.
• Diabetes: Sugar helps yeast grow, so if a person frequently has high blood sugar levels, they are more likely to develop candidiasis.

Vaginal douches and sprays may also increase the risk of developing a vaginal yeast infection.

The treatment for a yeast infection varies, depending on the infections location and severity. For mild, occasional infections, a person can try over-the-counter options, such as topical creams, nail treatments, or vaginal suppositories.

However, it is important to speak with a pharmacist or doctor first, because the symptoms of a vaginal yeast infection are similar to those of bacterial vaginosis and some STIs.

These issues do not respond to yeast infection treatments. They require different approaches and can cause serious health complications if a person does not receive the necessary care.

Also, frequently using antifungal medicine unnecessarily may reduce how effective it is in the future.

For more severe or reoccurring infections, a person may need prescription antifungal medication. Pregnant women should not take the antifungal medicine fluconazole (Diflucan), as it may cause birth defects, the Office on Womens Health report.

Some home care strategies may help reduce yeast infection symptoms or prevent the issue from coming back.

Probiotic yogurt may help reduce the amount of yeast in the body. A 2013 pilot study involving 24 women showed that eating 8 ounces of probiotic yogurt per day reduced the presence of Candida in some cases.

However, this was a small study with mixed results. Also, the women had HIV, so their health responses may not reflect those of the general population.

Addressing the cause of the infection is important, especially if the infection keeps coming back. A person may benefit from:

• using a condom during sex
• avoiding the overuse of antibiotics
• switching to a different method of birth control
• better managing underlying conditions, such as diabetes

A person should talk to a doctor if they notice symptoms of a yeast infection. It is important to receive the right treatment for any infection, and correctly identifying the type of infection is the first step.

Yeast infections often cause changes to genital discharge and patches to form in the mouth or in skin folds.

A doctor can confirm the infection and recommend the best treatment, depending on the severity and the part of the body involved.
