Hives, medically known as urticaria, is a skin condition that is characterized by red, itchy bumps that may appear anywhere in the body; skin, lips, tongue or even ears. Hives have the tendency to move around from one part of the body to another and also change its shape as well as size. Hives appear to be pale, in wheals and appear all of a sudden right after a response of the body to allergens for no identified reason. This means that it can appear at no certain date and time. In various times of the day, this allergies appear and disappear. They might be there in the morning, but disappear in the afternoon and then come back at night.
Hives are categorized into 3 types, with respect to the length of time they last:
1. Acute - This particular type only appears for a very short time. Lasting for days or up to 1 week, this type is popular to many. This could be a result of infection like the cold virus and drugs like pain killers and muscle relaxants, insect's stings just like bees and wasps, allergies from some foods like nuts. Commonly, hives appear 30 minutes, right after consuming the food
2. Chronic - This usually lasts for 1 and a half month up to a year. This kind of hives upset daily routines as it appears and vanishes repeatedly, and its causes are unidentified.
3. Physical - This is commonly caused by excessive heat from the sun or unexpected changes of temperature. Normally, this may also be triggered even by prolonged touching on certain objects.
Causes This specific allergic reaction is normally due to blood plasma leaking to tiny skin blood vessels. Additionally, it is a response to histamine, which is a chemical secreted by the mast cells which are near the blood vessels of the skin. The reaction which causes the fluids to leak on the skin then lets hives to show up. Histamine is liable for the characteristics of hives; redness, itching and the swelling.
Allergies On normal instances, hives come out as an allergic reaction. These include: bee stings, particular foods, medicine and sunlight exposure. It also prompts histamine release that usually reacts with the skin.
Though there are no known causes of hives, it occurs in 3 identified causes:
(a) Idiopathic This implies that the appearance of hives has no known reason. They simply appear of nowhere and abruptly disappear.
(b) Immunological Changes in the immune system can cause hives. The occurrence of hives is triggered by histamine secretions due to immune system triggers.
(c) Non-immunological This type occurs when foreign compounds result in histamine secretion without proven connection to the immune system. By the time an individual gets close with these substances, hives may appear.
It is recommended to keep yourself away from substances which can cause hives to appear, for example allergens that result in reactions.
