Why do we experience Atopic Eczema in Allergies?

The disease is generally a symptom of one of the trio namely, asthma, allergies and hay fever. It has a deep connection with allergies. It is an autoimmune condition. The immune system reacts to otherwise harmless proteins and causes the body to produce IgE antibodies. These antibodies react and bind with the protein and causes the mast cells underneath the skin to release histamine. Histamine causes irritation in the nerve endings and brings forth the discussed skin condition.
