Urticaria in teenagers

Overview

Urticaria, also called hives, is a skin condition that causes raised, itchy, red or skin-colored bumps. These bumps happen when the body releases a chemical called histamine, which makes small blood vessels leak fluid into the skin. In teenagers, hives are usually not serious and often go away on their own.

Yes, urticaria is very common, especially in teenagers. Many teenagers will get hives at least once.

It affects both boys and girls, but it may be slightly more common in girls during the teenage years.

Symptoms

Common symptoms

• Raised, red or skin-colored bumps that are very itchy.
• Bumps may feel warm or sting.
• They can appear suddenly and change shape and location.
• Individual hives usually fade within 24 hours, but new ones may appear.

Symptoms in children

• In younger children, symptoms are the same but they may not be able to describe the itchiness well.
• Hives can be more widespread and cover larger areas.

Symptoms in older adults

• Hives in older adults are less common, but symptoms are similar.
• They may be more persistent and take longer to resolve.

Causes

Main causes

• Allergic reactions to foods (like peanuts, eggs, or shellfish).
• Allergic reactions to insect stings or medications (like antibiotics).
• Physical triggers: heat, cold, pressure, exercise, or sunlight.
• Infections, especially viral illnesses like the common cold.
• Stress or emotional upset.

Risk factors

• Having other allergic conditions like asthma, eczema, or hay fever.
• Personal or family history of hives.
• Recent infection or illness.
• Being under a lot of stress.

When to see a doctor

See a doctor urgently if:

• If you have hives with breathing problems, swelling of the face or throat, or dizziness – call emergency services immediately.
• If hives appear after taking a new medicine or being stung and are spreading quickly.

Book a routine appointment if:

• If hives last longer than 6 weeks.
• If they keep coming back without an obvious cause.
• If they affect your sleep, school, or daily life.

Diagnosis

A doctor will ask about your symptoms, what you were doing before the hives appeared, and look at your skin. Often, no tests are needed.

Tests that may be done

• If hives are chronic or the cause is unclear, the doctor may recommend allergy tests.
• Blood tests can help rule out other conditions, like thyroid problems or autoimmune diseases.

What to expect at your appointment

Your doctor will examine the hives and ask about your history. They may ask you to keep a diary of when hives occur and what you were doing, eating, or taking.

Treatment

Treatment focuses on relieving itching and avoiding triggers. Most cases get better with simple measures and over-the-counter remedies.

Self-care at home

• Avoid known triggers, like certain foods, heat, or tight clothing.
• Apply a cool, wet cloth to the itchy areas.
• Wear loose, soft cotton clothing.
• Use over-the-counter antihistamines (choose a non-drowsy type for daytime).
• Do not scratch, as it can make hives worse or cause infection.

Medical treatments

If self-care is not enough, a doctor may prescribe antihistamines at a higher dose or a different type. For severe or chronic hives, short-term courses of corticosteroid medication or other prescription treatments can be used. Always follow your doctor's advice.

Living with this condition

For most teenagers, hives come and go. You can live a normal life by avoiding triggers and taking medication when needed. Hives are not contagious.

Lifestyle tips

• Keep your home and bedroom cool.
• Take cool or lukewarm showers, not hot ones.
• Use gentle, fragrance-free soaps and lotions.
• Find ways to manage stress, like exercise, hobbies, or talking to a friend.

Diet and exercise

If certain foods trigger your hives, avoid them. Exercise can sometimes cause hives, but staying active is healthy. If exercise triggers hives, talk to your doctor about ways to manage it.

Mental health and emotional wellbeing

Chronic hives can be frustrating and embarrassing. It's normal to feel upset or anxious. Talk to your parents, a school counselor, or your doctor about your feelings. You are not alone.

Prevention

It is not always possible to prevent hives, but you can lower your risk by avoiding known triggers. If you have allergies, strict avoidance of those allergens helps. Managing stress may also reduce flare-ups.

Complications

If left untreated

• If hives are part of a severe allergic reaction (anaphylaxis) and left untreated, it can be life-threatening. This is rare.
• Chronic hives can lead to sleep problems, poor concentration at school, and emotional distress.

Long-term outlook

The outlook is very good. Most hives are short-lived and cause no lasting harm. Even chronic hives usually improve over months to a few years. Treatments are effective, and most teenagers live active, normal lives.
