Urticaria is an allergic reaction. Urticaria is a limited edematous reaction due to the dilation of small blood vessels in the skin mucosa and increased permeability that occurs after a patient is exposed to an allergen. Patients with urticaria can affect the function of the respiratory and digestive tracts and can even be life-threatening if the symptoms flare up more severely. If urticaria occurs, it must be treated aggressively. The first step is to isolate the cause of the hives, and identifying the allergen is a key step. Anti-allergy medications such as paracetamol and benadryl antihistamines should then be targeted. If the patient has a severe allergic reaction, glucocorticoids can be used in conjunction. However, it should be emphasized again and again that the fundamental approach to treating urticaria is to confirm the diagnosis of the allergen and to avoid exposure. Care should also be taken to avoid certain factors that may induce an exacerbation of urticaria. Patients should not be overly stressed and should be emotionally stable. At the same time, it is important to take rest, not to overexert oneself, and to combine work and rest. The diet should be controlled by taking a light diet and not eating foods that are too spicy and stimulating.
