Eczema is not one kind of a condition but a rage of conditions affecting the skin. Examples of these conditions include atopic dermatitis, irritant dermatitis, contact dermatitis, light sensitive dermatitis as well as dyshidrotic dermatitis. Of all these types of eczema, the atopic dermatitis is the most common.
What are the causes of eczema?
It is not well understood exactly what causes of eczema are but the condition has a genetic predisposition. In other words, if someone in your family (especially the parents) suffered hay fever or asthma at one time, then you are susceptible to getting it. The rest are generally what we will refer to as trigger factors. Eczema by itself is not an allergy but a reaction to allergy. Allergies are some of the causes of eczema. They include dust mite, pollen, pets among others.
Other causes of eczema include irritants. These are substances which cause a reaction when they come into contact with the skin. They include heat and sweat. As such, if you exercise and the body heats up, you will have a reaction to the heat. The sweat will also cause an irritation on the skin.
Some weaknesses in the immune system have been found to cause the onset of eczema. There are two triggers to eczema: internal and external factors. The internal triggers affect the immune systems, leading to eczema. One of them is allergic reactions to certain foods such as dairy products. These products like milk may trigger an auto-immune response in the body, akin to an attack by a foreign body.
Hormones also play a role in the immune system, hence the eczema attack. These hormones include the testosterone hormones which may flare up, triggering an eczema attack.
Identifying the causes of eczema is key to finding a lasting solution to the problem. Although this condition has no cure, there are home remedies and medication that can be used to relieve the symptoms.
