Allergic reactions are rather common medical conditions that affect so many people. They occur when your body, particularly your immune system, does not recognize a foreign substance that has entered it and reacts negatively against it.
You may have allergies to specific foods and conditions that you are not aware of until you have consumed or been exposed to them. When you are having an allergic reaction, which is colloquially termed as an “attack”, you experience several types of negative bodily occurrences. Sometimes, it would be something as minor as a rash or an itchy feeling. But it can also extend to conditions as severe as anaphylaxis and difficulty in breathing as in an asthma attack.
Allergens, which are substances or foreign items that can cause allergic reactions, are varied and very different. Most people are already familiar with what substances they are allergic of. But in general, these allergens are those that irritate your nasal passage and that are branded by your immune system as harmful for your body.
Foods are the most common causes of allergic reactions. Many are allergic nuts, shellfishes, shrimps and crops. Among fruits, strawberries are probably the most likely to trigger an allergic reaction. While you may not be allergic of dairy products and poultry, there would also be times when you would experience reactions like rashes against them if you have already been consuming too much of it for a few days.
Medicines can also trigger allergic reactions. Among them are antibiotics like aspirin, amoxicillin and penicillin. Pain relievers like mefenamic acid and even anesthesia may also cause allergies especially if the immune system does not find any use for them in your body.
Substances that have too much chemical content in them like detergents and dyes can also cause allergic reactions. In other cases, environmental factors such as pollen, dust, hay and (rarely) temperature may also merit hypersensitive reactions such as allergies.
Allergic reactions can be triggered by just about anything around you. There may be cases where these are inherited, meaning they may have run in your family for generations already. What is important is that you are aware of them. Sometimes, allergies would catch you off guard and affect you rather severely. But if you know what they are and how they affect you, then it would be a lot easier to avoid them and save yourself from being sick.
