Aetiology
Complex allergic or hypersensitivity conditions are caused by an overactive immune system. This overactivity can be caused by a variety of things, such as exposure to certain allergens, certain medications, or a genetic predisposition.
Diagnosis
Diagnosis of complex allergic or hypersensitivity conditions involves a detailed medical history, a physical examination, and a variety of tests to identify the trigger. These tests may include skin prick tests, patch tests, blood tests, and immunoglobulin E tests.
Differential diagnosis
Complex allergic or hypersensitivity conditions can be difficult to differentiate from other conditions that produce similar symptoms. These conditions include asthma, food allergies, eczema, rhinitis, and drug allergies.
Treatment
Treatment for complex allergic or hypersensitivity conditions depends on the underlying cause and the severity of the condition. Treatment typically involves avoiding the triggers, medications to reduce symptoms, and, in some cases, immunotherapy.
Prognosis
The prognosis for complex allergic or hypersensitivity conditions depends on the underlying cause and the severity of the condition. In most cases, symptoms can be managed with avoidance of triggers and medications, but some cases may be more severe and require long-term treatment.
