Really What Causes Allergies?

what causesMost people in the world are suffering from some kind of allergy or other. The majority of these people are wondering the causes allergies. If you are suffering from an allergy, you may blame the common allergens: pollen in the air, furs, and dust mites for your symptoms. But most of these allergens are harmless and innocent by themselves. What causes allergies really is your own immune system. The immune system will mistake these innocent allergens for a serious threat and attack them. In reality, the symptoms of an allergy are the results of the body’s misguided attack.

The risk of developing an allergy starts with ones own genetics. Even though specific allergies are not inherited, the tendency of having allergies can come from your own genes. If one parent is prone to allergies, a child has a 35% chance of developing allergies. A child with both parents being prone to allergies, have a 70% chance of developing allergies as he or she grows. Most allergy-prone people will not develop reactions to all allergens. But when the circumstances are right, the potential to trigger allergic reactions is quite large in such persons.

People who come into contact with allergens when their immune system is weak, are more likely to develop allergies themselves. It all begins with exposure to allergens. Even if you have inhaled an allergen numerous times in the past, you may not develop and allergy until your body flags it as an invader. The exact reason for this process is still unknown. During this kind of exposure, the immune system will study the allergens and build antibodies and special cells to detect it. Then when you are exposed to this allergen the next time, your immune system starts to act and the antibodies will recognize the allergens. Then the special cells known as mast cells will be activated. They will produce allergy symptoms in the skin, lungs, lining of the nose and intestinal track. These mast cells will then burst open and flood the system with chemicals such as histamine. These chemicals are responsible in causing allergy symptoms like swelling. Swelling can be responsible for runny nose and asthma etc.

Allergies may get worse with time or may not get worse. It would greatly depend on the immune system of the particular individual. Children may outgrow an allergy completely with time. Older people will find their allergy symptoms lessening with age. But some people may find their allergies getting worse over time. External factors can play an important role in worsening or reducing allergy symptoms of these people. A heavy pollen season or a new job in a moldy office can have a negative effect on the allergies of these people and worsen their allergies.

Allergies must be managed well if you are to be relieved of them completely. Poorly managed allergies can lead to severe symptoms such as sinus infection and full-blown asthma. Take care of your allergies and see your doctor immediately. This will help to get rid of the allergy symptoms quite easily.
