Skin Allergies – Cause And Effect

Allergies that result in rashes, bumps, itching, redness and other skin conditions are very common, and their cause can sometimes be very hard to identify. Rashes can be caused by many things, including plants (such as poison ivy), allergic reactions to a medication or food, or illness (such as measles). Eczema and hives, which are both related to allergies, are two of the most common skin rashes.


Eczema, or atopic dermatitis, affects between 10 – 20 percent of children and 1 – 3 percent of adults. Eczema presents itself as dry, red, irritated and itchy skin. When infected, the skin may have small, fluid-filled bumps that ooze a clear or yellowish liquid. Eczema sufferers, more often than not, often have a family history of allergies. Although the majority of children outgrow eczema, for adults who continue to suffer, it is a serious condition.

Adult eczema is a chronic condition that creates inflamed, red, itchy patches of skin that can erupt in oozing flare-ups. Many areas of the body can be affected for adults, including face, hands, and even eyelids. The itching for adults can become unbearable as flare-up can affect skin all over the body. There are treatments and medications, which can help, manage some of the itchiness and pain caused by eczema.


Hives, alternately known as urticaria, affects about 20 percent of people at some time during their lives. Many substances or situations can lead to a case of hives. A case of hives usually starts as an itchy patch of skin that turns into swollen red welts. The itching may be mild to severe. Scratching the area, alcoholic beverages, exercise and emotional stress all may worsen the itching.

Some common triggers for hives include:

  • Some food (especially peanuts, eggs, nuts, and shellfish)
  • Medications, such as antibiotics (especially penicillin and sulfa), aspirin and ibuprofen
  • Insect stings or bites
  • Physical stimuli, such as pressure, cold, heat, exercise or sun exposure
  • Latex
  • Blood transfusions
  • Bacterial infections, including urinary tract infections and strep throat
  • Viral infections, including the common cold, infectious mononucleosis, and hepatitis
  • Pet dander
  • Pollen
  • Some plants, such as poison oak and poison ivy.
  • Contact Dermatitis


Contact dermatitis is a skin condition that results from exposure to something to which you’re either sensitive to or allergic to.

This condition is a red, itchy rash caused by a substance that comes into contact with your skin. The rash isn’t contagious or life-threatening, but it can be very uncomfortable. Possible causes include soaps, cosmetics, fragrances, jewelry, and plants, such as poison ivy or poison oak. It is possible that people are exposed to substances at work that may trigger contact dermatitis.

To treat contact dermatitis successfully, you need to identify and avoid the cause of your reaction. Unfortunately, this can sometimes be difficult.  If you can avoid the offending substance, the rash usually clears up in a few weeks. To ease the discomfort, you can try soothing your skin with cool, wet compresses, anti-itch creams, and other self-care steps.
