Symptoms of allergies can manifest as respiratory, gastric or skin symptoms. The symptoms may vary from mild to severe based on the patient’s immune response to the allergen.
Respiratory: Itching of the eyes, sneezing, running nose, wheezing, asthma, bronchitis, cough, chest tightness and shortness of breath are the most common symptoms of respiratory allergies.
Skin: Raised, itchy bumps, rashes, redness of skin, mosquito-bite allergies, hives, itching and swelling are some of symptoms seen on the skin.
Gastric: Bloating of the stomach, abdominal cramps, diarrhoea and vomiting are symptoms seen in gastric allergy.
Diagnosis of allergies is conducted in three ways.
Allergies may be mild in most cases. However, in some cases, allergies may be life threatening and may trigger certain complications, which have to be treated immediately. Complications include the following:
Anaphylaxis: It is a serious, life-threatening allergic reaction. The most common anaphylactic reactions are to foods, insect stings, medications and latex.
Asthma: A patient with an allergy has a tendency to have asthma. This will affect the airways and breathing.
Atopic dermatitis (eczema), sinusitis and infections of the ears or lungs: The patient’s tendency to getting these medical conditions is higher if they have allergic rhinitis, a pet or a mould allergy.
Fungal infections: Fungal infections are easily contracted by patients having allergies.
