Hives, or urticaria, is a sudden itchy rash on the skin. The size and color of the hives on the skin may vary from person to person. This hives condition can be triggered by factors such as allergies, certain foods, heat, and exercise. We wrote this article to explain the causes of hives and what can trigger it.

What Causes Hives?

The causes of hives cause the cells in the skin to release chemicals such as histamine. These chemicals cause fluid to leak from tiny blood vessels under the skin. This liquid creates bubbles. Also, the chemicals secreted cause blood vessels to enlarge, which creates redness around the blisters.

The reasons for the occurrence of all these events can be listed as follows;

Foods: Certain foods that are also associated with allergies can trigger hives in people with sensitivities. These foods are;

  • Seafood
  • Peanut
  • Tree nuts
  • Egg
  • Milk
  • Chocolate

Medications: We can say that almost any medication can trigger hives. The most common known trigger drugs are; penicillin, aspirin, anti-inflammatory, blood pressure medications.

Common allergens: Allergens such as pollen, pet dander, hair, latex, and insect bites can cause hives.

Environmental factors: Conditions such as heat, cold, sunlight, water, pressure on the skin, emotional stress and exercise can cause hives.

Underlying health problems: Hives can also occur due to underlying health problems. Blood donation, immune system disorders, some thyroid-related conditions, infections caused by viruses or bacteria such as HIV, Hepatitis are examples.

Genetics: Like all allergic diseases, hives may be due to genetic factors. Any allergic disease in your child’s parents or relatives may be the cause of hives.

What Are the Risk Factors of Hives?

  • If urticaria or angioedema has been overcome before,
  • If you have any allergic disease,
