9 Common causes of urticaria

1. Due to food
When there is a food allergy, the body's immune system will identify the food as a foreign factor and form an allergic reaction to fight them. It can be said that hives are a common symptom of food allergies. Some protein-rich foods that are easy to cause allergic reactions are seafood, peanuts, chicken skin, eggs, etc.

2. Due to drugs
All drugs can cause urticaria. The most common are antibiotics. Medicines for colds, arthritis, and blood pressure can all cause urticaria. Sometimes a person is only allergic to farmed shrimp, not to marine shrimp due to antibiotic residues in livestock products.

Drug-induced urticaria usually occurs immediately after taking the drug or several days after taking it.

3. Due to respiratory agents
Inhalation of allergens such as pollen, house dust, warehouse dust, feathers, smoke, mold, fragrance. Therefore, to prevent this disease, the patient should clean the accommodation regularly.

4. Due to infection
Viral infections such as hepatitis B and C; bacterial infections in the ears, nose, and throat; digestive organs, teeth, mouth, urinary tract, genitals, intestinal parasites (worms, flukes) or fungal infections of the skin and internal organs. Infections are sometimes latent, undetected.

5. Due to the venom
From the bites of some insects such as mosquitoes, fleas, bees, ants, worms. Often the cause is easy to spot. Some species as small as bed dust mites are sometimes missed.

6. Due to chemical exposure
From cosmetics, lipsticks, powders, perfumes, hair dyes, nail polishes, pedicures, soaps, etc. Food colorings and food preservatives can also cause urticaria.

9. Heredity
If someone in the family has had urticaria, the possibility that a family member will have the disease is not small.

Patients with symptoms such as redness, itching, discomfort, etc. need to go to a medical facility with a specialty in Dermatology to be examined and tested to find out the direct cause of the disease.
