When a person is allergic to something, the body and immune system react by releasing histamine. Skin cells react to histamine and leak the fluid into the top layer of the skin (known as epidermis) and that reaction provokes the inflammation, itchiness and hives. Usually, hives are very small and in some people they might look like mosquito bites, or be even tinier than that.
Hives are very common, and some estimation says that more than 20% of people worldwide experienced this condition. Avoiding allergens that cause hives is the best way to prevent them, as many people have learned. If you have hives, there are good chances your condition will heal on its own, but it is advisable to see the doctor and identify the cause of your problem. Any serious health complications associated with hives, such as breathing difficulties, abdominal cramps or dizziness, must be immediately taken care of by a medicalprofessional.
What Causes Hives
There are so many different things people might react to by hives that it’s hard to mention all of them. Certain food and food additives, insect bites, plants and cosmetic ingredients are some of the possible causes of hives. One could also get hives if he is allergic to pollen, latex or even hair bleach. Diseases can also provoke the same problem, including: mononucleosis, rheumatic fever, mastocytosis and carcinoma. Additionally, people may react to UV rays, heat or cold in the same way.
You should find efficient treatment for the hives you have been experiencing, to relieve the burning and itching. In some cases, hives may indicate another underlying disease, such as: malaria, lupus, lymphoma, thyroid problem or hepatitis B.
Antihistamines and epinephrine injections are the medical treatments for hives. Antihistamines block the production of histamine, responsible for hives. There are some OTC (over the counter) antihistamine medications and you can find Chlor-Trimeton or Benadryl in the pharmacies. Your doctor may also prescribe some of antihistamine drugs, like Allegra and Zyrtec.
Severe hives are sometimes treated with epinephrine (adrenaline). If you suffer from sudden and serious hives, your doctor could recommend carrying this injection with you and taking it when in need.
Hives can sometimes also be successfully managed taking a cool shower or a cold compress. Wear loose clothes and avoid strenuous exercise until the hives resolve.
Stress could also induce hives. When that happens, think about some stress management, and try to avoid highly emotional stress that has led to hives.
