Hay Fever is also medically termed as rhinitis. It can be divided into Allergic Rhinitis and Non-Allergic Rhinitis.
Nearly 20% of people will get hives at some point in their lifetime. While they may not be life-threatening, hives can potentially cause both physical and emotional issues, particularly if they occur frequently.
Hives are predominantly caused by allergies. Hives can either be classified as acute urticaria or chronic urticaria. Whereas acute urticaria develops suddenly and lasts about 24-48 hours, chronic urticaria can last more than six weeks. Most people experience recurring bouts of acute urticarial. However, non-allergic hives, also referred to as idiopathic urticaria, are independent of any allergens. Research shows that non-allergic hives tend to affect more females than males.
It’s usually very easy to identify hives, thanks to their highly distinctive symptoms:
Hives will appear on your skin when your body releases histamine. The production of histamine can be caused by a number of factors, including;
There is one particular condition that looks strikingly similar to hives. This condition is known as Angioedema.
With Angioedema, the swelling happens right beneath your skin. The term edema is used to describe a deep swelling that appears around your eyes, hand, lips, genitals as well as feet.
Angioedema symptoms usually stay longer than urticaria, even though the swelling may subside within 24 hours.
Your doctor will conduct a physical exam. Depending on the outcome of that particular exam, your doctor may recommend additional skin tests as well as blood tests to determine the primary cause of your hives.
Some persistent hives may warrant a skin biopsy to help establish the root cause. If the cause of the hives is identified, such as an allergen trigger, you might need to undergo further tests.
As already explained, the majority of urticaria cases will clear up on their own within a day or so. And episodes of hives should stop disappearing and reappearing within a few weeks.
If your hives symptoms persist for more than six weeks, it could be a sign that you have a chronic condition. It’s highly advised to schedule an appointment with your doctor if your hives continue for this long.
Hives generally clear up on their own without the intervention of any treatment. However, in some cases, some people may experience a few complications such as anxiety, depression, and anaphylaxis, which can be a life-threatening condition.
