Rashes

What is a rash?

Rash is a general term, used to describe many different types of skin conditions. In most cases, a rash is defined by changes in the skin, and it may be red, bumpy, or blistered. Depending on the circumstances, rashes can range from very small to covering a large portion of the body. Most people develop rashes at least occasionally throughout their lifetimes.

What causes rashes?

Typically, a rash is a symptom of another skin condition, or a health problem that affects the skin. Some of the most common causes include:
  • An allergic reaction to a medication.
  • Impetigo or other bacterial infection.
  • Ringworm or other fungal infection.
  • Chicken pox or other viral infection.
  • A reaction to touching an allergen such as poison ivy.

Symptoms of rashes

The symptoms of rashes can vary widely. The most common include:
  • Discolored skin, especially redness
  • Welts or other raised areas
  • Dry, scaly areas
  • Blisters
  • Rashes frequently itch
  • If symptoms such as fever or difficult breathing accompany a rash, it may be a sign of a more serious medical problem requiring prompt attention.

How to prevent rashes

Because a rash is usually triggered by another problem, the best way to prevent it is to keep your skin healthy and avoid allergens. Follow these tips to help prevent skin irritation:
  • Keep your skin hydrated by using moisturizer immediately after bathing or hand washing.
  • Avoid contact with anyone who has a skin infection.
  • When shaving, only use clean razors.
  • Only use non-irritating cleansers, soaps, fragrances, and cosmetics.
  • Ask your dermatologist what skin care products are best suited to your skin type.

Most of the time a rash can be treated with an over-the-counter moisturizer, anti-itch cream, or antihistamine formula. However, if the underlying cause of the rash is still present, the skin will continue to be irritated.
