Hives Causes
Have you ever had those tiny red bumps on your skin that get itchy and irritated? These aren't just common rashes, they can be hives. Hives are also known as uritcaria and are actually a skin disorder that a lot of people encounter. These raised red bumps which are itchy can be caused by a number of things, which are both allergic and non-allergic. chances are if the hives last for less than a week then the cause of the hives are allergic. If the condition persists for more than six weeks then the cause of the hives could be due to something else.
The most common cause of hives is an allergy. There are certain foods, which can bring about this allergic reaction. The intake of nuts, berries, eggs, medication and even insect bites can all bring about hives if you are allergic to any of these. Animal dander can also trigger hives and the same goes with wearing tight clothing or jewelry if you are allergic to certain fabrics or metal. When an allergen becomes present in the body, an inflammatory reaction takes place causing the capillaries to leak into the dermis, which results in an edema. Histamines and other chemicals which hamper inflammation are released into the body. This leads to the hives that you then see on your skin.
Physical stimulation that is direct can also cause the release of histamine in the body giving rise to hives. Extreme heat or cold, the sun, water and sweat can all bring about the appearance of hives as well. Friction and pressure can also bring about the same results. All these are stimulants for hives, which can be caused by an allergic reaction. Stress and anxiety can also lead to the appearance of hives; since this is something that is a physiological reaction of the body. Situations which bring about tension, anxiety and stress can have you red and scratching all over.
Less common causes of hives are non-allergic; which means to say that it can also be something that is genetic in nature. In other cases it may also be idiopathic or with no known definite cause. It is neither triggered by stimuli nor genetic. Hives as a result of an infection may also occur.
