5 Causes of Hives

At Allergy Relief Clinics in Richardson, Texas, Dr. Rafiquddin Rahimi can help treat acute hive outbreaks, figure out what caused them, and help prevent them from coming back.

Hives 101

Hives, also known as urticaria, are red, pink, or white welts that rise up from the skin and often sting, itch, or burn. Hives are typically caused by the body having a strong response to some sort of irritant, which triggers a histamine release. 

In response to the histamine, your blood vessels can leak blood plasma, which causes swollen spots. Hives can be acute, meaning an isolated incident or just a few incidents with a clear trigger, or chronic, which can mean they occur frequently, and there is no fixed cause.

Common causes of hives

In most cases, hives are caused by the body having an allergic reaction. This can be to something you have eaten or drunk, or to something in your environment. However, hives can also be caused by other factors. Some of the most common causes of hives include:

1. Allergens

The most common causes of hives are allergens like foods, medications, bug bites, pollen or pet dander. These can be the easiest types of hives to control, as Dr. Rahimi can often identify the allergens involved and help you create a plan for hives prevention.

2. Pressure

Pressure on the skin, also called dermatographism, can cause hives in some people. Wearing loose-fitting clothing can help, as hives usually form around spots like waistbands or anywhere else clothing is tight.

3. Infection

Common bacterial infections like strep throat or urinary tract infections can also cause hives.

4. Temperature

Some people are particularly sensitive to heat or cold. You might break out in hives as a reaction to prolonged heat exposure or exercising in the heat, or get hives when you go out in the cold in winter or jump into a cold body of water.

5. Chronic illness

Chronic hives are common in people with chronic health problems such as celiac disease, lupus, type 1 diabetes, rheumatoid arthritis, or thyroid disease. In such cases, the hives are an ongoing symptom of an underlying condition. 

If you or your child are suffering from an acute outbreak or hives or a chronnic condition that is accompanied by hives, Dr. Rahimi can help prescribe a course of treatment or a mitigation plan. Call our office at 972-435-0338, or make an appointment online.
