ATOPIC DERMATITIS CAUSES |
|
|
While allergic reactions often trigger
atopic dermatitis, the condition is thought to be the result of an
inherited over-active immune system or a genetic defect that causes
the skin to lose abnormally large amounts of moisture. The condition
can be aggravated by a cycle that develops in which the skin itches,
the patient scratches, the condition worsens, the itching worsens,
the patient scratches, etc. This cycle must be broken by relieving
the itching to allow the skin time to heal. If the skin becomes
broken, there is also a risk of developing skin infections which, if
not recognized and treated promptly, can become more serious.
Symptoms of atopic dermatitis include the following:
An itchy rash and dry, thickened skin on areas of the body where
moisture can be trapped
Continual scratching
Chronic fatigue, caused when itching disrupts sleep.
An individual is more at-risk for developing the condition if there
is a personal or family history of atopic dermatitis, hay fever,
asthma, or other allergies. Exposure to any of the following can
cause a flare-up:
Hot or cold temperatures
Wool and synthetic fabrics
Detergents, fabric softeners, and chemicals
Use of drugs that suppress immune-system activity.
Certain foods, such as peanuts, cow's milk, eggs, and fish, can
trigger symptoms of atopic dermatitis. A small percentage of
patients with atopic dermatitis find that their symptoms worsen
after having been exposed to dust, feather pillows, rough-textured
fabrics, or other materials to which dust adheres. |
