Understanding And Getting Rid Of Intertrigo Rash

Intertrigo is a skin rash commonly occurring where two skin surfaces rub together, such as in the armpits, groin, and under the breasts. It can cause redness, itching, burning sensations, and other uncomfortable symptoms. In this article, we will discuss intertrigo rash and its causes. We will also look at some of its common symptoms and treatments.

Causes of Intertrigo Rash

Intertrigo rash is caused by a combination of factors, including friction, moisture, heat, and microorganisms like bacteria or fungi.¹

It can also be caused by wearing tight clothing that causes chafing.

Sometimes, it may also indicate an underlying medical condition such as a skin infection or allergy.

Candidal intertrigo is the most common type of intertrigo and is caused by an infection with a fungus.

Tinea cruris can cause similar symptoms to intertrigo, but it is not the same condition and does not directly cause intertrigo.

However, both Tinea cruris and intertrigo can be caused or exacerbated by similar factors such as excessive sweating, friction, and heat. In some cases, individuals with tinea cruris may also develop intertrigo as a secondary infection, particularly if the area is not kept clean and dry or if there are other underlying skin conditions present.

It is important to note that while tinea cruris and intertrigo may have similar symptoms, they require different treatments.

Tinea cruris is typically treated with antifungal medications, while intertrigo may need treatment with a combination of topical treatments, self-care measures, and lifestyle changes to manage underlying risk factors.

Some of the factors that can increase the risk of developing intertrigo rash include:

1. Obesity: Excessive body weight can lead to skin folds and increased friction between the skin, which can contribute to the development of intertrigo.
2. Heat and humidity: Warm and humid environments can create the ideal conditions for the growth of microorganisms that can cause intertrigo, such as bacteria and fungi.
3. Diabetes: People with diabetes are at a higher risk of developing fungal infections, which can cause intertrigo.
4. Weakened immune system: Conditions that weaken the immune system, such as HIV/AIDS or certain medications, can increase the risk of developing intertrigo.
5. Skin conditions: People with preexisting skin conditions, such as eczema or psoriasis, are more prone to developing intertrigo due to the inflammation and rubbing that occurs in skin folds.
6. Age: Intertrigo is more common in infants and elderly people, as their skin is more susceptible to irritation and inflammation.
7. Occupation: Certain professions requiring prolonged standing periods, such as nurses or chefs, can increase the risk of developing intertrigo due to increased pressure and friction on the skin.

Symptoms of Intertrigo Rash

Some of the common symptoms of intertrigo are:

• Rash with red, swollen areas on either side where the skin rubs together
• Soreness
• Burning sensation

The symptoms of intertrigo rash can vary in severity depending on the area. In some cases, there may not be any itch or redness. In other cases, the skin may be sore and develop a blister.

Blisters caused by intertrigo can be very painful and may cause itching, burning, or a sensation of tightness or soreness in the affected area. If the blisters burst or break open, they can become even more painful and more prone to infection.

In addition, open sores or bleeding may be seen due to skin picking.

Is Intertrigo Contagious?

Intertrigo itself is not contagious and does not spread from person to person. However, if the underlying cause of intertrigo is a fungal or bacterial infection, these microorganisms can spread to other areas of the body or other people through direct contact.

In addition, if the intertrigo is not treated properly, it can worsen and spread to other body areas. For example, if left untreated, a case of candidal intertrigo in the groin area could spread to the inner thighs or buttocks. Therefore, it is important to seek treatment for intertrigo as soon as possible to prevent its spread and worsening of symptoms.

Diagnosing and Treating Intertrigo Rash – What Are the Best Options?

Diagnosing intertrigo rash usually involves a visual examination of the affected area. Your doctor may sometimes perform a culture test to determine if an underlying bacterial or fungal infection is present.

The following signs may indicate that it is time to see a doctor for an intertrigo rash:

• The affected area becomes more inflamed, painful, or swollen
• The rash spreads to other parts of the body
• The rash develops into blisters or open sores
• You have a fever or chills
• You develop symptoms of a bacterial or fungal infection, such as pus, discharge, or foul odor

Treatment of Intertrigo Rash

The treatment of intertrigo rash usually involves a combination of self-care measures and medication. Over-the-counter medications, such as topical antifungal or antibacterial creams, can also be used to help treat intertrigo rash.

Tips To Prevent Intertrigo

You should take the following steps to reduce moisture and friction in the affected area just like Tinea cruris:

• Wearing breathable clothing made from natural fabrics
• Avoiding tight-fitting garments
• Keeping skin clean and dry
• Using an antifungal powder or cream to prevent infection
• Avoiding activities that cause excessive sweating.

In addition, weight loss, particularly in obese individuals, and treatment of underlying medical conditions like diabetes mellitus, and immunosuppressive conditions may reduce the recurrence of the disease.
