Causes of Eczema
The precise cause of eczema is still unknown but current theories suggest that it’s related to an abnormal immune response and genetic factors.
⦁ Abnormal Immune Response
It’s linked to an over reactive response of the body immune system to the irritant. It’s a condition in which the immune system becomes overactive, means overreact or start attacking the body, leading to inflammation. Eczema permits significant loss of fluids through the skin allowing the allergens to penetrate.
⦁ Some Allergies
The most general triggers are the substance that irritates the skin. These skin allergies may be due to wool, chemical detergent, make up, dust, pollen or pet fur, cigarette smoke, certain jewelries, cosmetics and perfume depending upon the person.
For some eczema can occur due to use of some rough or coarse material. Certain food like eggs, wheat, nuts, and dairy products can also cause the trigger. Changes in weather condition can also lead to eczema in certain person. Use of some chemical detergents, soaps, animal dander can also be the cause of trigger.
Eczema mostly runs in families. If any of your family members is suffering from eczema or if there is a family history of other allergic conditions such as asthma or hay fever then it’s most probable that a person will develop eczema. Eczema is not contagious but it’s inherited so it is common in between the same family members affected by eczema.
⦁ Other Causes
Chronic circulatory problems leads to increase in fluid build ups in the legs leading to skin irritation in the lower legs. It mostly occurs to middle aged and elderly people.
Hormone levels & stress are too one of the factors that trigger eczema or worsen the condition. In women the symptoms worsen during menstruation cycle or during pregnancy. Mental stress can further aggravate the condition.
