hello Madam, most of the times it's a misconception that urticaria is caused by food items. In very negligible cases patients are actually allergic to food items. We advise the patients to avoid packaged foods with preservatives,artificial colors & flavours,seafoods. Urticaria is very disturbing for the patient because of severe itching. So to get rid of this irritating condition treatment is necessary. Sometimes urticaria can be a manifestation of internal diseases and hence they should be ruled out by going for specialist consultation. Thanks
