Itchy Hives At Night Causes

Itchy Hives

The medical term for Hives is Urticaria, which is an allergic skin condition, characterized by the formation of wheals as itchy red bumps, swellings or welts on the skin. Hives can be formed as small spots or can also be formed as big blotches with a few inches in diameter. Itchy Hives are of two types. They can be acute or chronic. Acute Hives can last from one day up to a few weeks and chronic hives last for months and even years in some cases. Hives are not usually life threatening but can cause a lot of discomfort ranging from pain to severe burning at the affected area.

Acute Hives are caused by allergic reactions to various otherwise harmless substances like food (shell fish, nuts, dairy products etc), environmental toxins, and chemicals found in processed foods. Medications, insect bites and other allergens like pollen from flowers can also cause itchy hives. The causes for chronic hives are idiopathic meaning “hard to pinpoint”. In some people with chronic urticaria hives, general stress can also be one of the causes. Autoimmune urticaria is caused by the person’s own immune system reaction and hence the term. The causes for this immune system response are often hard to pin point. Anti-bodies called immunoglobulin-E (IgE), attach to and stimulate the mast cells (part of the body’s immune system) to release a chemical substance called histamine which makes the superficial blood vessels and capillaries more permeable (leaky). These leaked fluids then enter the skin tissues and cause allergic reactions and result in itchy hives. Mast cells can also be stimulated by physical stimuli like direct injury, and environmental factors like exercise, heat, cold, pressure on the skin.

Itchy hives can be problem for many people of all ages. Hives in toddlers can be a common occurrence with causes being allergies and physical stimuli. Children tend to exert more pressure on the hives by scratching them causing even more inflammation.

People usually have specific triggers that cause the hives to appear. By keeping track of the triggers and trying to eliminate their contact, you can prevent the hives from forming. But in severe cases of discomfort, it is advisable to consult an immunologist, who will analyze and evaluate the specific causes for your hives and prescribe correct treatments.
