Rashes can have multiple causes, from mild to serious. The most common include:

• Allergic reactions (food, drugs, chemicals)
• Infections (viral, bacterial, fungal, or parasitic)
• Autoimmune diseases (such as lupus or psoriasis)
• Dermatologic conditions such as atopic dermatitis or contact dermatitis
• Exposure to the sun, heat or insect bites

The origin can vary greatly, so it is important to evaluate the context and other associated symptoms.

Eruptions can look very different from each other. Some appear as small, flat red spots; others, such as pimples, blisters, crusts, dry plaques, or inflamed areas. The texture can also vary: soft, rough, flaky or moist. Some of them hurt or itch, while others don't cause discomfort. The location also gives clues: a rash on the face is not the same as a rash on the trunk, or one that appears only after exposure to the sun.

If a rash appears suddenly, spreads rapidly, or is accompanied by fever, difficulty breathing, facial swelling, or general malaise, medical attention should be sought immediately. It's also important to check if the rash doesn't improve over time, becomes painful, oozes, or reappears frequently.

Some rashes can be prevented. Using gentle personal care products, protecting yourself from the sun, avoiding known allergens and not sharing objects such as towels or cosmetics are habits that help reduce risk. In prone individuals, maintaining an adequate dermatological routine and consulting on time can prevent complications or recurrences.

Do not self-medicate. Many people use creams without diagnosis, which can make the situation worse. The ideal is to consult a dermatologist to identify the source and establish an appropriate treatment. In Dzeus Health, our professionals are ready to help you both in person and virtually.
