Skin Disorders - Causes






Dermatitis

Contact and atopic dermatitis are allergic reactions. Allergic reactions are caused by the body's immune system. The immune system is a network of organs, tissues, cells, and chemicals designed to fight off foreign invaders, such as bacteria and viruses. Sometimes the immune system reacts to substances that are normally harmless to the body. It attacks the harmless material in the same way it would attack a disease-causing organism. Such responses are allergic reactions.

Allergic reactions can be caused by a great variety of objects, including:

  • Flowers
  • Herbs
  • Vegetables
  • Chlorine
  • Household cleansers
  • Detergents and soaps
  • Fabric softeners
  • Glues
  • Perfumes
  • Certain types of medications

Statis dermatitis is caused by poor circulation in the legs. Fluids collect in the lower legs, and they begin to swell. The swelling may cause a red, itchy rash.

The cause of nummular dermatitis is not known. A number of factors that can increase the risk for the disorder include hot or cold weather, stress, allergies, and bathing more than once a day.

Seborrheic dermatitis is cased by an over-production of oil glands in the skin.

Psoriasis

The cause of psoriasis is not known. However, researchers have identified a number of factors related to the occurrence of the disorder. These factors include:

  • History of psoriasis in a person's family
  • Stress
  • Exposure to cold temperatures
  • Injury, illness, or infection
  • Use of steroids or certain other medications

Vitiligo

The cause of vitiligo is not fully understood. There appears to be a strong genetic factor involved. That is, the disorder seems to occur commonly in certain families. The condition is usually triggered by some stressful event, such as an accident, job loss, death of a family member, severe sunburn, or serious illness.
