Chronic
urticaria, also called Ordinary urticaria, is defined as the
presence of passing wheals, which lasts for more than six weeks. Chronic
urticaria causes include allergic, non-allergic, genetic, and
immunological factors. Chronic urticaria can be triggered by various
factors, such as drugs, extreme pressure, temperature extremes,
friction, intensive exercise, and sunlight. In most patients, chronic
urticaria causes are unknown. Up to 40% of chronic urticaria cases
have an autoimmune cause. Extreme emotional conditions, such as stress,
may directly or indirectly provoke a tendency to develop
urticaria.
Urticaria
Causes
What causes urticaria is a very
difficult question to answer, as there are known and unknown causes for
this skin condition. Following, are the major urticaria causes:
Idiopathic Causes: Though there are many
known causes for urticaria, there are many unknown causes as well,
which are called idiopathic causes. Most people have idiopathic causes
for urticaria, which is why it is on the top of my list.
Drugs: Manmade drugs are considered to
be the major cause of urticaria. These drugs include different
antibiotics (Penicillin), hormonal preparations, anti-inflammatory
drugs (aspirin, indomethacin), vaccinations, NSAIDs, foreign sera, and
contraceptive pills, etc. Morphine-induced urticaria has been reported
in some patients. The urticaria patients who use cocaine or those who
inject heroin may suffer from Bronchospasm.
Allergens and Food allergens:
Different allergens can cause urticaria; however, the individual's
hypersensitivity plays a major role in this. Many artificially
flavored foods and some natural foods, such as wheat, milk, eggs,
cheese, cereals, peas, oranges, fish, and chicken can also cause
urticaria.
Synthetic Products: Urticaria may also
be induced in response to the excess usage of synthetic products, such
as deodorants, colognes, talcum powders, and other cosmetic products.
Other Causes: Other causes of urticaria
include infections and infestations, emotional factors, alcohol,
and environmental factors.
