Fungal Infections: Everything You Need to Know

In recent years, fungal infections have become more prevalent worldwide. It only causes discomfort but also becomes an underlying issue for others issues. The infections can be pretty assorted, from minor skin infections to infections of the fingernail or toenail and even internal organs. This blog explains the different kinds of fungi that cause these infections and how they are supposed to be managed and treated.

Fungal infections are caused by invasive fungi that overgrow a host's tissues with generalised health problems. These organisms particularly like the moist and warm conditions of the human body and can cause colonisation and infection. The symptoms of fungal infections can range from mild irritations such as itching to systemic diseases, depending on the type of fungus and location involved. This fungus needs to be explicitly identified as it would determine the most suitable strategy for treatment.

Common Types of Fungal Infections

The pathogens that cause fungal disease can be categorised into three major types: dermatophytes, yeasts, and moulds. 

Dermatophytes

• Majorly infect the skin, hair, and nails.
• Cause some of the most common diseases, such as athlete's foot and ringworm.
• Survive by digesting the keratin of these tissues.
• Highly Contagious

Yeasts

• Infect individuals, particularly with decreased immunity.
• May lead to systemic infections that are potentially more serious.
• Moulds

Infections are less common

• Infections are less common.
• Pose a significant risk for respiratory issues when fungi infect the lungs.

Symptoms of Fungal Infections

Fungal infections can appear in different parts of the body, and their symptoms vary depending on the area affected. Recognising these symptoms early can help you seek the right treatment.

Skin Infections

The skin is often the first place where fungal infections become noticeable. Common symptoms include itching, redness, and rashes. For example:

•  Athlete's Foot: This infection typically affects the area between the toes. You might notice peeling, cracked skin that feels itchy or burns. The skin may also appear red and moist.
•  Ringworm: Despite its name, ringworm is a fungal infection not caused by a worm. It presents as a round, red rash with clear skin in the centre, giving it a ring-like appearance. The rash can be scaly and very itchy.

These skin infections can be uncomfortable but are usually treatable with over-the-counter creams or prescribed medications.

Nail Infections

Fungal infections can also target the fingernails or toenails. Signs of a nail infection include:

•  Discolouration: Nails may turn yellow, brown, or white.
•  Thickening: The nails become thicker than usual and may be difficult to trim.
•  Brittleness: Infected nails can become brittle and crumble easily.
•  Shape Changes: The nail might change shape or lift from the nail bed.

These symptoms can make nails look unsightly and cause discomfort or pain, especially when wearing shoes or using your hands.

Systemic Infections

In more severe cases, fungi can enter the bloodstream and spread throughout the body, leading to systemic infections. Symptoms of a systemic fungal infection can include:

•  Fever and Chills: These are common signs that your body is fighting an infection.
•  Difficulty Breathing: If the lungs are affected, you might experience shortness of breath or coughing.
•  Fatigue: A general feeling of tiredness or weakness.

Systemic fungal infections are severe and require immediate medical attention. They are more common in individuals with weakened immune systems, such as those undergoing chemotherapy or with certain chronic illnesses.

Causes of Fungal Infections

Fungal infections occur when fungi overgrow in or on our bodies; several factors can make this more likely. Let's explore the main causes:

Environmental Factors

The environment plays a significant role in the development of fungal infections. Fungi flourish in warm, wet places like public swimming pools, spas, and locker rooms. These places are also prone to barefoot walking and surface contact; thus, going to such places carries the risk of infection. This, about individual hygiene, is most relevant when the said microorganisms manage to stay on the skin. Simple practices might risk a fungal infection, such as one person not properly drying themselves after a bath or sharing used towels and shoes.

Risk Factors

Certain predispositions make certain groups of individuals more likely to get fungal infections. Patients who are immunocompromised, such as during HIV AIDS illness or Cancer treatment, are more prone since their bodies find it difficult to ward off infections. Chronic disease conditions like diabetes also make one more susceptible. High glucose levels can also predispose dieters to illnesses, especially in those who have diabetes, as high glucose levels promote fungal growth, and diabetes reduces blood flow as well as immune function.

Besides that, the continued use of antibiotics will confuse the natural balance of microorganisms in your body. Your antibiotics set to kill the nasty, harmful bacteria will also kill off some of the good bacteria that keep the fungi in check. Things are just mixed up, and to the benefit of the fungus, it starts to grow wildly and gives you an infection such as thrush or a yeast infection. Good hygiene practices can minimise the risk of fungal infection, avoid communal areas, and controlling underlying health conditions.

Diagnosis of Fungal Infections

Physical Examination

Diagnosing a fungal infection typically starts with a thorough physical exam. During this exam, healthcare providers look for visible signs of infection and may ask about medical history and symptoms to understand the full scope of the issue.

Laboratory Tests

Once that is done, they will send the patient for various laboratory tests. Confirmatory tests, such as cultures, skin scrapings, or blood tests, help identify the specific type of fungus causing the infection. These tests are crucial for determining the most effective treatment plan and are, therefore, an essential part of the entire diagnosis process.

Treatment Options for Fungal Infections

Treating fungal infections depends on where and how severe they have become. Here are the common ways to treat them using simple methods.

Topical Treatments

For infections on your skin or nails, doctors often suggest antifungal creams, lotions, or ointments. You apply these medicines directly to the infected area. They work by killing the fungus or stopping it from growing. It's essential to use them precisely as directed, usually for several weeks, to ensure the infection completely disappears. These treatments are convenient and can be bought over the counter or prescribed by a doctor.

Oral Medications

You might need oral medications if the infection is more severe or doesn't improve with topical treatments. These are pills or liquids you take from the mouth. They work throughout your body to fight off the fungus. Oral antifungal medicines are beneficial for stubborn nail infections or infections that have spread deeper into your body. A doctor will prescribe these and monitor you for any side effects.

Home Remedies

Along with medical treatments, specific home care steps can help you recover faster. Keeping the affected area clean and dry is important because fungi love moist environments. Wash the area gently with soap and water, then dry it thoroughly. Wearing loose, breathable clothing can prevent moisture from building up. Some people use natural remedies like tea tree oil or apple cider vinegar, but it's a good idea to talk to a doctor before trying these.

Prevention Tips for Fungal Infections

Hygiene Practices

Good personal hygiene is crucial in preventing fungal infections. This includes keeping the skin dry and clean, especially in fold areas such as under the breasts or the groin. 

Lifestyle Adjustments

Avoid sharing personal items like towels and toiletries that can transfer fungi from one person to another. Wearing footwear in communal areas like locker rooms or pools can also help reduce your risk of infection.
