Hives or urticaria is basically an allergic skin condition that is distinguished by severe itchiness and red-colored wheals that vary in size from small-sized spots up to plate-sized welts. Take note that hives can abruptly manifest on any part of the body and can last for 24 hours up to a few days while chronic cases are known to last for weeks or even years. The common treatment that has been used in the treatment of hives is the application of over-the-counter topical antihistamines.
Allergies to certain foods
Those who develop an allergic reaction to certain foods are likely to develop hives. This has been the most common cause of hives, especially when foods such as fish, milk, shellfish, eggs and nuts are eaten by the individual. Even food additives such as sulfites and salicylates can cause hives in some individuals. Primarily, an individual who has food allergy can experience the itching of the tongue or swelling of the mouth and lips. This would be followed by the development of hives in a span of minutes or hours after the exposure.
Pain relievers and antibiotics can trigger an allergic reaction in some individuals which includes hives and swelling. Other medications such as aspirin, codeine and non-steroidal anti-inflammatory drugs (NSAIDs) can also trigger the development of hives. Take note that NSAIDs can also initiate life-threatening swelling of the tongue or throat that can lead to the blockage of the airways. Even blood pressure medications such as ACE inhibitors can cause recurrent episodes of angioedema in some individuals that can eventually lead to hives.
Allergy to insect bites and stings
The stings and bites from insects such as yellow jackets, bees, fire ants and hornets are known to trigger mild hives and swelling among individuals with allergies. The hives typically subsides in a few hours. On the other hand, those who are allergic to insect bites and stings can experience a severe life-threatening reaction which is called anaphylaxis. This type of reaction involves severe itchiness, swelling all over the body and development of hives along with breathing difficulty, fainting and rapid heart rate. Anaphylaxis requires immediate medical attention. If an EpiPen is available, it must be administered to counteract the symptoms. Being prepared is important if a family member is prone to severe allergic reactions. With this in mind, you can register for first aid training Winnipeg today.
