Chronic urticaria

Chronic urticaria is an inflammatory skin condition that results to formation of wheals and/or angioedema. The skin condition is considered chronic if it lasts more than 6 weeks.

The condition can be instigated by various factors including certain drugs, bacterial infections, autoimmune conditions and physical exposure to certain substances. Any part of the body can be affected, but usually the neck, head, back, chest, legs and arms are involved. The intense itchiness might result to ulceration of the skin and scarring.

What are the potential risk factors?

  • Family history
  • Bacterial infection with the Helicobacter pylori bacteria
  • Roundworm infection that affects the stomach
  • Certain reactions to drugs such as non-steroidal anti-inflammatory drugs (NSAIDs), antibiotics and pain medications
  • Consumption of alcohol
  • Using substances such as certain perfumes, caffeine and detergents
  • Food allergies such as shellfish or peanut in rare instances
