What are hives? Hives are a form of a skin reaction that is usually caused by being exposed to particular substances, foods and drugs. Hives which are also known by the name of urticaria can result in the formation of red marks on the skin which itch a lot. The sizes of these red marks vary from person to person and can be anywhere from small specks to large marks spanning many inches.
Angioedema is a similar type of skin reaction to hives which results in the swelling up of the layers of skin present around the lips and the eyes. Mostly, angioedema and hives do not cause much trouble and go away completely without leaving any scars even if you don’t receive any treatment for them.
What Causes Hives?

Release of histamine in the blood is the body’s natural response when it is exposed to a substance that it is allergic to. This histamine is responsible for causing itchiness, swelling and a number of other symptoms. Although hives are pretty common, people who suffer from allergies like hay fever are more at risk of developing hives.
Hives are usually caused by exposure to substances like pollen and animal dander, taking certain medications, insect bites and consuming foods such as milk, eggs, shellfish and nuts. In addition to this, hives can also develop because of doing excessive exercise, emotional stress, too much sweating, sun exposure, infections like mononucleosis and certain diseases like leukemia, lupus and some autoimmune disorders.
