HivesHives are itchy red welts that develop as a result
of reactions to foods and other substances.
It is more commonly known as utricaria.
Certain medications can also cause hives. Patients without allergies can develop hives often
being stung by an insect or touching certain plants (poison oak or poison ivy). Hives are usually accompanied with other
symptoms including swelling of other parts of the body. Food allergies as well can provoke swelling
of the lips and mouth. Hives can
be triggered by many things, including:
In up to
90% of outbreaks of hives, a trigger is never found despite extensive testing;
these cases are referred to as idiopathic urticaria. In cases of
idiopathic urticaria outbreaks, hives are most likely caused by a reaction from
the person's own immune system (autoimmune reaction). If hives are accompanied by swelling of the throat and difficulty
breathing, speaking or swallowing, they could signal anaphylaxis, a potentially
fatal medical emergency. Homeopathy |
