Hives have two main characteristics—they itch and they swell. They vary from the size of a pimple to the entire chest or back area. They can appear individually or join together to form large patches. They can appear for a few hours or last days before fading or just disappearing.
Hives form as an adverse reaction to histamine–a chemical and part of the body’s natural immune system, being released in response to pathogens that are foreign to the body. Histamine is needed in order for capillaries to be able to accept the white blood cells and various other compounds necessary to withstand the invasion of pathogens.
Multiple factors are involved in histamine release—allergic reactions, insect bites/stings, chemicals in foods, food additives and coloring, exposure to sunlight, heat, cold and/or medicines can all cause the process. It is a normal part of our immune’s defense but as those who suffer hives with none of the above as a viable cause, they can be a mystery.
One possibility is the digestive system’s inability to function correctly. For whatever purpose, the waste is being forced from the skin’s excretory system rather than through the colon and eliminated in the normal fashion. If this is the cases the skin is hit with pathogen from all sides.
The aim of a lifestyle or dietary change is to help the body reach and/or maintain optimal immune system health. In many cases a complete dietary revision is essential to solve the problems of chronic hives since food borne chemicals and/or antigens are likely involved. And unfortunately, there are no tests that can reliably identify them.
Check food labels carefully. Stay clear of excess food additives in processed foods as well as yellow #5 food coloring (known to cause hives). Do not take medications such as Bufferin, Excedrine, Alka-Seltzer or Anacin as they all contain aspirin. Also watch those containing salicylates such as Pepto-Bismol.
Since hives are triggered by the histamine release increase the consumption of foods that are high in vitamin B3 (niacin), which has the ability to inhibit its release. Good sources of niacin include seafood, poultry, seeds/nuts and whole grains—including cereals and breads. Drink plenty of water throughout the day to help flush toxins.
Quercetin is a bioflavonoid found in apples, raspberries, red grapes, cherries, citrus fruits, black and green tea, red wine, onions, broccoli, and leafy greens (apples, cherries and berries can cause allergic reactions, so take care) that have beneficial antioxidants to help fight pathogens. Green tea has polyphenols that are beneficial to some as antihistamines.
Those affected by hives should try a high-fiber diet which will automatically improve digestion and reducing the necessity of using skin to expel toxins. Deeply colored vegetables–high in carotenoids will aid the skin in resisting the sun rays. Cold water fish should be eaten several times a week as essential fatty acids aid in reducing inflammation.
