What Foods Should Be Avoided in Chronic Urticaria?

Urticaria commonly occurs in many individuals during seasonal transitions. If not promptly controlled, it may recur repeatedly. What foods should patients with chronic urticaria avoid?

Foods to Avoid in Chronic Urticaria

Patients with chronic urticaria should avoid foods known to trigger allergic reactions—such as mangoes, shrimp, peaches, eggs, and milk. These should ideally be excluded from the diet. Additionally, spicy and irritating foods, as well as certain hair-care products, should also be avoided whenever possible. Effective management of chronic urticaria requires visiting a hospital for allergen testing followed by desensitization therapy. Concurrently, traditional Chinese medicine (TCM) may be used to bolster immune function, thereby facilitating complete resolution of the condition.

Urticaria is a relatively common allergic disorder affecting the skin and mucous membranes. Its hallmark features include transient, localized, edematous, erythematous wheals accompanied by intense pruritus. Lesions appear one after another and leave no residual marks. Histopathologically, it reflects transient edema in the superficial dermis. Most cases are triggered by allergies—specifically Type I hypersensitivity—and etiologies are complex, particularly in chronic urticaria. Prior to the appearance of wheals, patients often experience localized pruritus or stinging sensations on the skin, followed rapidly by eruption of the rash. In some patients, systemic symptoms—including anorexia, malaise, headache, or fever—may develop several hours to one or two days after onset of the rash.

Patients with chronic urticaria should actively investigate and eliminate potential underlying causes. A thorough clinical evaluation is essential to identify triggers such as photosensitivity, cold or heat sensitivity, Helicobacter pylori infection, or other infectious or inflammatory conditions—and treatment should be tailored accordingly.
