How to Teat Hives – Causes and Preventions

Updated on August 21, 2011

Hives, commonly known as "urticaria", has the following main symptoms:

  • Rashes suddenly appear on the skin, in different shapes and sizes, rashes usually have the colors of red or white, hives occur and disappear both rapidly.
  • Hives can attack several times a day, with intense itching and clear boundary around the flush.
  • Some patients may have fever, and reactions of the gastrointestinal tract with symptoms like abdominal pain and diarrhea accompanied with rashes.
  • Some patients may have skin scratch disease, if their skins are scratched with blunt objects, there will be localized flushing and edema.
  • If hives simply cause swelling of the eyelids, lips and external genitalia instead of other obvious skin rashes, this is commonly known as angioedema.
  • Hives are common among young children, mainly are allergic reactions caused by mosquitoes and other insects.

Hives mostly occur in spring and summer season, there may be scattered papules and severe itch, it is easy to have a secondary infection after scratching, in situation when skin rashes disappear slowly, this is commonly known as rash-like urticaria.

Most experts believe that this disease is due to allergies (such as eating fish, crabs, milk or other protein rich foods), stimulus (such as cold, heat, wind and mental factors), drug and other factors could lead to skin tissue cells releasing histamine, small blood vessels expanding, increasing permeability of blood vessels, and the formation of localized blood vessels wall edema.

If the disease occurs in the throat, it can cause throat swelling and breathing difficulties, or even cause suffocation, it should be treated a timely manner. Acute urticaria can sometimes occur in sepsis patients, they should promptly go to hospital. 

Acute hives can be curd in about 1 week, however, chronic disease can last for months or even years.

Because there are many reasons causing hives, food is also a major factor in its pathogenesis. Some people with hives will see immediate result of turning better after they changed their diet, while other patients, especially those with chronic urticaria, often fail to get better even if they paid special attention to their diet and stop eating some foods for a long time. So the question is, under what circumstances should the patients change their diet?

Foods that must be avoided contain:
1, If a food is identified as the stimulating factor of hives, you should stay way from it in the future to avoid recurrence. 

2, Patients with acute hives should avoid spicy foods, seafood, wine and other foods that are irritating and easy to cause allergies, so as not to aggravate urticaria symptoms. 

3,If the etiology is unclear, in addition to not eating the spicy food, you need to carefully think about the foods you have just eaten, whether they are high-protein foods, especially fresh fish, shrimp, crab, mutton, beef, eggs, milk, etc., to find out the cause of the disease. Foods including some of the vegetables, fruits, certain food ingredients, preservatives can not be ignored, because these substances can sometimes cause allergies without being noticed.

4, If after strict control of diet, there is still no improvement in skin symptoms, you should consider whether other incentives exist, then there is no need to avoid the above foods anymore

5, Since chronic hives are developing through a long process, it’s best that patients do not restrict their diet blindly, but they should do some careful observation and analysis instead to find out and remove foods that can precipitate or aggravate symptoms obviously, because long-term food restriction is also detrimental to your health. 

Why do some patients have abdominal pain with hives?

Some of urticaria is accompanied by onset of abdominal pain, which is a rather peculiar phenomenon. Because abdominal pain and urticaria have some relationship, if the abdominal pain is followed by hives, it is often due to food factors, meaning intestinal parasites cause gastrointestinal tract inflammation and trigger some allergic reactions, it is the allergens produced by intestinal substances that lead to hives on the skin. If hives is followed by stomach pain, it is often because the body has produced a substance called histamine that acts on gastrointestinal mucosa and leads to abdominal pain, diarrhea and other gastrointestinal symptoms. There are also some people, in tension, heat or exercise, can produce a substance called acetylcholine, which stimulates the skin and gastrointestinal tract, and leads to hives. So it is very important to figure out the relationship between hives and abdominal pain before any action is taken.
