Hives are a skin condition characterized by raised, red, non-scaly patches of varying sizes. These patches are itchy and can appear suddenly on any part of the body. They typically fade within 24 hours without leaving marks, but new patches may recur repeatedly.
Acute Urticaria: Hives lasting less than 6 weeks.
Chronic Urticaria: Hives persisting longer than 6 weeks.
Food: Seafood, certain nuts, preservatives, food coloring.
Medication Allergies: Antibiotics, painkillers.
Insect Stings/Bites: Ants, bees, wasps.
Contact Allergies: Latex, animal fur.
Infections: Viral, bacterial, fungal, or parasitic.
Endocrine Disorders: Thyroid disease.
Physical Triggers: Heat, cold, pressure, sunlight, exercise.
Certain Cancers: Lymphoma.
Autoimmune Disorders: The immune system attacks the body.
Unknown Causes: Many cases have no identifiable trigger.
Identify and Avoid Triggers: Key to preventing recurrence.
Antihistamines:
These block histamine, reducing itching and swelling.
Short-acting or long-acting types; some patients require multiple medications.
Advanced Therapies: For severe cases unresponsive to antihistamines, doctors may prescribe medications that suppress inflammatory mediators (e.g., corticosteroids, leukotriene inhibitors).
Acute Hives: Usually resolve within 1–2 weeks after trigger removal and antihistamine use.
Chronic Hives: May persist long-term if the cause is unknown or untreatable.
Avoid known triggers (e.g., specific foods, physical stimuli).
Always carry antihistamines for immediate relief during flare-ups.
Do not scratch the affected area to prevent skin damage or infection.
Take medications as prescribed and inform your doctor of any side effects.
Go to the hospital immediately if hives are accompanied by:
Chest tightness or difficulty breathing.
Severe abdominal pain.
Swelling of the face, lips, or eyes.
Dizziness or fainting.
