Inducible urticaria refers to cases where wheals appear after relatively constant stimuli, such as exercise, increase in body temperature, cold air or water, pressure, and friction. The type of stimulus and the reaction time are checked together.

What is inducible urticaria?

This is a type of urticaria where wheals recur after specific stimuli such as heat, cold, pressure, or friction. Inducible urticaria refers to cases where wheals appear after relatively consistent stimuli, such as exercise and rising body temperature, cold air or water, pressure, and friction. Both the type of stimulus and the reaction time are checked.

How is it different from similar conditions?

It may appear alongside urticaria that occurs without a stimulus, and the shape and duration of the lesions differ from those of heat rash, contact dermatitis, or simple scratch marks.

Why is this important in skin care?

This is necessary to specifically determine the situations to avoid and the treatment goals for cholinergic urticaria, cold urticaria, and dermatographism.

What should be checked based on my symptoms?

If systemic urticaria, dizziness, or difficulty breathing occurs after swimming in cold water or intense exercise, seek emergency help immediately.

Condition GuidanceCholinergic UrticariaCholinergic urticaria commonly presents as multiple small wheals of about 1 to 4mm appearing within minutes after body temperature rises and sweating occurs due to exercise, hot environments, hot showers, spicy foods, or nervousness. The wheals may be itchy, burning, or tingling, and may start on the torso and neck before spreading to the limbs and face. They usually subside within a short time once the triggering situation stops, but in rare cases, they may be accompanied by swelling of the lips and tongue, wheezing, difficulty breathing, dizziness, fainting, abdominal pain, or diarrhea. If there are changes in breathing or consciousness, do not wait for simple skin symptoms to resolve and seek an emergency evaluation immediately.Condition GuidanceCold UrticariaCold urticaria involves itchy, red, or darker-than-skin-tone wheals, tingling, burning, and deep edema after exposure to cold air, cold water, or cold objects. Holding a cold object can cause fingers to swell, and cold drinks can cause angioedema of the lips, tongue, and throat. After extensive cold exposure, especially swimming in cold water, systemic wheals, difficulty breathing, wheezing, abdominal symptoms, palpitations, hypotension, dizziness, or fainting may occur. Wheals may become more distinct when the skin warms up again after the cold stimulus ends.Condition GuidanceDermographismDermatographism is a condition where raised red lines or wheals appear along lines where the skin was lightly scratched or rubbed by collars, towels, or bedding. It is accompanied by swelling and itching, appearing within minutes of stimulation and usually subsiding within 30 minutes. In symptomatic types, it can occur even with light pressure, and itching may worsen in the evening or at night, affecting sleep and fatigue levels. Rarely, the reaction may be delayed and persist for several hours. If wheals appear throughout the body regardless of stimulation, or if they are accompanied by swelling of the lips, tongue, or throat, dyspnea, or a feeling of fainting, it is not considered solely dermatographism.Medical Evaluation GuideDistinguishing between rashes that disappear within hours and dermatitis that lasts for daysFirst, observe whether swelling in the same area generally fades without leaving a mark within a day, or whether it stays for several days, leaving dead skin, oozing, or scabs. Wheals that disappear and reappear in different locations suggest urticaria (hives), while long-lasting surface changes suggest other types of dermatitis; however, a diagnosis requires looking at the overall progression.Medical Evaluation GuidePrepare for your visit with skin photos, symptoms, and medications usedRather than a single photo, please prepare a chronological record of the date the symptoms first appeared, the timing of when they disappear and reappear, itching and pain, and the medications used and your reactions to them. It is helpful for the medical evaluation to take photos of the same area from the same distance during both normal states and when symptoms are most severe.
