In some cases, the bodys immune system, which comprises the lymphatic system, can overact to certain allergens such as pollen, certain medicines/chemicals, and even certain foods. When the body notices an allergen for the first time, it normally produces the necessary antibodies including IgE antibodies and B memory cells to fight it.

However, when the same allergen appears again, the body is likely to respond by releasing excess antibodies to fight it, especially the IgE antibodies that attach themselves to mast cells and trigger the production and release of histamine, which eventually causes inflammation in certain parts of the body.
