Urticaria: Five Things to Know About Hives

Picture yourself going about your day when suddenly, your skin erupts into a raging itchy rash. This itch can leave you feeling uncomfortable and bewildered. This might get diagnosed as urticaria, more commonly known as hives. While it may not be as debilitating as fibromyalgia, which we've discussed in the previous article, urticaria can still significantly impact your quality of life. Today, we're delving into the itchy, bumpy realm of hives to arm you with knowledge and understanding.

In the next few minutes, we’ll answer five crucial frequently asked questions regarding urticaria that could change the way you view this common yet often misunderstood condition. From its sneaky symptoms to potential dietary triggers, we'll explore the ins and outs of hives, in five minutes or less. But before we dive in, it’s important to note that this is a common condition and there are things that can be done to lessen or eliminate its effects in your life. Did you know that, according to the British Association of Dermatologists, urticaria affects up to 20% of people at some point in their lives? That's right, you're not alone in this itchy battle.

So, without further ado, let's scratch beneath the surface and uncover the five things you need to know about urticaria, aka hives.

1.   What exactly is urticaria, and why does it happen?

Like an unwelcome guest, it shows up unexpectedly and causes much discomfort and, sometimes, a feeling of embarrassment. But what's really going on beneath the surface?

At its core, urticaria is an immune reaction, that may be part of a wider allergic response. Your immune system, usually your stalwart defender, suddenly goes into overdrive. It releases a substance called histamine, which causes small blood vessels to leak. The result? Those telltale red, itchy welts we call hives.

But here's where it gets interesting or concerning. Urticaria can be triggered by a veritable smorgasbord of factors:

• Foods (think shellfish, nuts, or eggs). We’ll touch on this some more later in the article.
• Medications
• Insect bites or stings
• Physical stimuli (like pressure or cold)
• Stress (yes, your mind can make you itchy)
• Infections

However, in many cases, the exact cause remains a mystery, making it somewhat tricky to diagnose in some cases.

2.   What are the symptoms of hives?

Now, you might be thinking, "Surely, I'd know if I had hives?" Well, not always. Urticaria can be a deceptive, presenting in various ways that might catch you off guard.

The classic symptoms include:

• Welts: Raised, often red bumps on the skin
• Itching: Can range from mild to severe
• Swelling: Particularly in the lips, eyelids, or throat.

But here's where it gets tricky. These symptoms can appear and disappear faster than it can take you to get seen by your doctor making it sometimes more difficult to diagnose. One moment you're itching like mad, the next, your skin looks perfectly normal. This on-again-off-again nature is one of urticaria's hallmarks. Physically being examined by a healthcare provider is crucial for the journey to recovery.

3.   Are there different types of urticaria I should be aware of?

Yes. There are different types of urticaria that are commonly experienced. What are they and what differentiates them?

• Acute Urticaria:
  • Lasts less than six weeks
  • Often triggered by specific allergens or infections
  • Usually resolves on its own
• Chronic Urticaria:
  1. Persists for more than six weeks
  2. Can last months or even years
  3. Often has no identifiable cause
• Physical Urticarias:
  • Triggered by physical stimuli e.g., dermographism (hives appear when skin is stroked), cold urticaria (triggered by cold temperatures), cholinergic urticaria (brought on by heat or exercise)

Understanding these distinctions is crucial, as they can influence treatment approaches and management strategies.

4.   How can I stop urticaria from impacting my daily life?

Living with urticaria can be like trying to navigate a maze blindfolded. The impact on daily life can be unexpected and profound, affecting everything from your wardrobe choices to your social calendar.

Imagine this scenario: You've got an important presentation at work, but you wake up covered in hives. Or perhaps you're planning a romantic evening, only to find your face swollen and itchy. Urticaria doesn't just affect your skin; it can take a toll on your confidence and mental wellbeing too.

But fear not. There are steps you can take to manage its impact:

• Identify and avoid triggers: Keep a diary to track potential causes.
• Dress smart: Opt for loose, cool clothing to minimise irritation.
• Cool it down: Apply cool compresses to soothe itchy areas.
• Stay moisturised: Use fragrance-free, hypoallergenic moisturisers to keep skin hydrated.
• Manage stress: Practice relaxation techniques like meditation or yoga.

Remember, while these self-help measures can provide relief, it's crucial to consult a healthcare professional for proper diagnosis and treatment. They might prescribe antihistamines or other medications to help control symptoms.

5.   Can my diet really influence urticaria symptoms?

The relationship between diet and urticaria is like a complex dance - intricate, sometimes unpredictable, but undeniably important.

While food allergies can certainly trigger acute urticaria, the link between diet and chronic urticaria is less straightforward. However, research suggests that what you put on your plate could indeed influence your symptoms.

Certain foods contain naturally occurring histamines or cause the body to release histamine. Foods high in histamine include:

• Fermented foods (think aged cheeses, wine, sauerkraut)
• Cured meats
• Certain fish (particularly if not fresh)
• Spinach and tomatoes
• Chocolate and citrus fruits

But before you clear out your fridge, keep in mind that not everyone with urticaria reacts to these foods.

Some sufferers find relief by following a low-histamine diet, while others get relief from anti-inflammatory foods like omega-3 rich fish, leafy greens, and berries. The key is to work with a healthcare professional or registered dietitian to identify your personal triggers and develop a balanced eating plan that works for you.
