If you want to have healthy skin, then you must know about skin allergy diagnosis and prevention of urticaria. Health conditions affecting the skin are very common and they include urticaria, hives, or nettle rash. They appear as red rashes of varying shapes and sizes that tend to change after a few hours. In addition, they cause itching and in some cases, angioderma or the swelling of lips, tongue, and eyes.
Skin allergy is caused by an oversensitive immune system which easily reacts to substances known as allergens. These substances are generally harmless and don’t cause allergies to most people. However, people with allergies respond to allergens by releasing histamines which in return cause itching, swelling, mucus production, muscle spasms, hives, urticaria, rashes and others.
Allergy diagnoses and tests
- Allergy testing
Health care providers conduct several tests to diagnose allergies and one of these is allergy testing. It is used to determine if the symptoms are an actual allergy or if it caused by other triggers. Most people are allergic to food allergens which include shellfish, beans, berries, tomatoes, milk, eggs and others. On the other hand, there are also those who are allergic to man-made drugs like penicillin, aspirin, codeine, sulfa, and other pollutants.
- Skin testing
Another effective way of diagnosing skin allergy is through skin testing. A doctor will conduct a prick test which involves placing a small amount of the suspected allergens on the skin, pricking the area to allow the substance to enter the skin. The doctor then observes and watches if there is any sign of skin reaction like swelling or redness. This test is often applied to children and babies.
- Blood testing
Sometimes a doctor will conduct a blood test to measure the levels of specific allergens in the body. A patient is required to have a complete blood count which can help reveal allergies. Usually, it is the eosinophil white blood cell count which is measured.
How to Prevent Skin Allergies
One can easily prevent skin allergies as early as during childhood. Studies proved that breastfeeding children for at least four months can already prevent certain allergies. You can also prevent them by avoiding those substances which you are allergic to. Avoid foods that cause rashes or itching as well as beauty products that irritate your skin. Moreover, you keep your pets out and bathe them regularly. Avoid going to places where there are many insects and bees too.
You can save yourself from allergens by gathering information on skin allergy diagnosis and prevention and by applying them to your daily life. Avoid what needs to be avoided. Allow yourself to be diagnosed and tested by your doctor. By doing so, you prevent urticaria and other allergies.
