Imaging tests. Images taken using CT or MRI can show details of your sinuses and nasal area. These might pinpoint a deep inflammation or physical blockage, such as polyps, tumors or fungi, that's difficult to detect using an endoscope.
Looking into your sinuses. A thin, flexible tube with a fiber-optic light inserted through your nose allows your doctor to see the inside of your sinuses. This can help your doctor see a deviated nasal septum, polyps or tumors.
An allergy test. If your doctor suspects that allergies might be triggering your chronic sinusitis, he or she might recommend an allergy skin test. A skin test is safe and quick and can help detect what allergen is responsible for your nasal flare-ups.
Samples from your nasal and sinus discharge (cultures). Cultures are generally unnecessary for diagnosing chronic sinusitis. However, when the condition fails to respond to treatment or is worsening, your doctor may swab inside your nose to collect samples that might help determine the cause, such as bacteria or fungi.
Lungs
Allergies can cause inflammation in your lungs. This inflammation can result in coughing, wheezing, shortness of breath, and other... symptoms.
The symptoms of allergies, such as nasal congestion and watery eyes, come from inflammation of your body tissues. Allergies can also cause inflammation in your lungs. This inflammation is the result of your body’s misguided attempt to protect itself from the allergens.
Allergies can cause lung problems. Exposure to allergens can cause allergy-induced asthma, a condition in which the airways swell and produce extra mucus.
Skin
Children and adults can develop different types of skin conditions. Skin disorders can occur for many reasons. One of the causes... is allergies.
An allergic reaction happens when the immune system has an unusual reaction to a harmless substance. The job of immune system cells is to find foreign substances, such as viruses and bacteria, and get rid of them. Normally, this response protects us from dangerous diseases. People with skin allergies have over-sensitive immune systems. They can develop allergic skin rashes and other conditions due to proteins found in food, pollen, latex, drugs or other things. The substances that cause allergic reactions are allergens.
GI Tract
Clinical features of gastrointestinal allergy include diarrhea, vomiting, abdominal pain and colic, intestinal hemorrhage and... malabsorption as well as symptoms and signs outside the gastrointestinal tract such as chronic rhinitis and asthma in the respiratory system, urticaria, angioedema and eczema as dermatological signs, headache, insomnia, hyperkinesis as central nervous system manifestations, failure to thrive and anaphylaxis as constitutional reactions. Milk allergy was discussed as an example of food allergy. Immunology of the gastrointestinal tract was presented, with examples of four types of hypersensitivity reactions, and gastrointestinal disturbances of immunodeficiency disorders and syndromes were named. Lastly, the autoimmune mechanism and the gut were described, with particular discussion of ulcerative colitis as an example of an autoimmune disease.
