bubble_chart Clinical Manifestations

In addition to gastrointestinal symptoms such as colicky abdominal pain, nausea, and vomiting, there may also be lip edema, urticaria, angioedema, purpura, bronchial asthma, allergic rhinitis, syncope, and hypotension.

bubble_chart Treatment Measures

Treatment involves avoiding allergenic foods, but sometimes identifying the allergenic food can be very difficult. When necessary, provocation tests can be conducted under close observation with emergency measures prepared. During an attack, sympathomimetic drugs, antihistamines, and adrenal corticosteroids are effective.

Laryngeal stridor requires tracheal intubation or tracheotomy.
