How Are Allergies Diagnosed?
Doctors can diagnose allergies in several ways. First, the doctor will ask about your symptoms and perform a physical examination. The doctor will also conduct an interview, such as what you have eaten recently and any substances your hands may have touched.
For example, if you have a rash on your hands, your doctor may ask if you have recently worn latex gloves. Finally, blood tests and skin tests can confirm or diagnose the allergen that the doctor suspects.
- Allergy blood test
Your doctor may order a blood test for the presence of an allergy-causing antibody called immunoglobulin E (IgE). IgE is a cell that reacts to an allergen. Doctors use blood tests to confirm the diagnosis if they are concerned about the potential for a severe allergic reaction.
- Skin test
The doctor may also refer to an allergist for testing and treatment. A skin test is a common type of allergy test performed by allergists. During this test, the skin is pricked or scratched with a small needle containing the potential allergen. Skin reactions were then documented. If you are allergic to certain substances, the skin will become red and inflamed.
Different tests may be needed to diagnose all possible allergies.
Allergy Treatment
The best way to avoid allergies is to stay away from anything that triggers a reaction. If that is not possible, there are some treatment options available.
- Treatment
Allergy treatment is done with drugs such as antihistamines to control symptoms. What the doctor recommends depends on the severity of the allergy. Therefore, you can check with a doctor first to make sure of your allergy.
Allergy medications include:
- Antihistamines
- Corticosteroids
- Cetirizine
- Loratadine
- Cromolyn sodium
- Decongestants
- Leukotriene modifier
- Immunotherapy
Immunotherapy means people with allergies will be given various injections over several years to help the body get used to the allergy. Successful immunotherapy can prevent allergy symptoms from returning.
- Emergency epinephrine
If your allergy is severe and life-threatening, take an emergency epinephrine shot with you. An emergency epinephrine shot will help fight the allergic reaction until medical help arrives. This is because some severe allergic responses can cause medical emergencies. Be prepared for this emergency situation by knowing first aid for allergic reactions.
- Natural remedy for allergies
There have been many natural remedies and supplements being marketed as treatments, to prevent allergies. However, make sure the product is BPOM based and discuss this with your doctor first. This is because some natural remedies can contain other allergens and make the symptoms worse.
For example, there are dry teas brewed using flowers and plants that are closely related to plants that can make your allergies come back. The same goes for essential oils. Some people use this oil to relieve common allergy symptoms, but on the other hand, essential oils also contain ingredients that can cause allergies.
Each type of allergy has natural remedies that can help speed recovery.
Preventing Symptoms
There is no way to prevent allergies. However, there are ways to prevent allergy symptoms before they occur. The best way to prevent allergy symptoms is to avoid the allergens that trigger them. An elimination diet can help determine the cause of the allergy so you can avoid it. To help avoid food allergens, read food labels thoroughly and ask questions when you are eating out.
Preventing seasonal, contact, and other allergies comes with knowing where the allergens are and how to avoid them. If you're allergic to dust, for example, you can help reduce your symptoms by installing the right air filters in your home, professionally cleaning your air ducts, and cleaning your house regularly.
Allergy testing can help pinpoint the exact trigger, which makes it easier to avoid. These other tips can also help you avoid an anaphylactic reaction.
Complications of Allergies
While you might think of allergies as colds and sneezes that come with every new season, some of these allergic reactions can actually be life-threatening.
Anaphylaxis, for example, is a serious reaction to exposure to an allergen. Most people associate anaphylaxis with food, but any allergen can cause signs:
- The airways suddenly narrowed
- Increased heart rate
- Possible swelling of the tongue and mouth
Allergy symptoms can lead to many complications. Your doctor can help determine the cause of your symptoms as well as the difference between a sensitivity and an allergy. Doctors can also teach you how to manage allergy symptoms so you can avoid the worst complications.
