Is It an Allergy, Intolerance or Sensitivity?

Any adverse reaction encountered by a person is often referred to as an allergy. This is said to be a rare case. Adverse reactions are often caused by an intolerance or sensitivity that has nothing to do with allergy.
According to the medical profession and studies shows that, an allergy involves the body’s immune system. It is a hypersensitivity reaction of the immune system to foreign substances, which are normally considered harmless. What happens in an allergic reaction is the immune system reacts to an allergen, which in turn causes a person’s own antibodies to attack the allergen. These antibodies are what produce various reactions.
Webster defines intolerance as “extreme sensitivity to a drug, food, or other substance.” it does not involve the immune system. Symptoms vary and always been mistaken for those of an allergic reaction but, because the immune system does not react with an intolerance, it will be very difficult to determine its source. One thing more allergic reactions are usually immediate, intolerance reactions can be delayed.
Other people believe that sinusitis is about allergies to different elements such as dust, smoke and other elements that might brought them allergies. In addition to allergens and viral or bacterial infection, sinusitis can be triggered by exposure to noxious chemicals, smoke, and air pollution. Due to the variety of sinusitis triggers, various forms of treatment are available as preventative measures and symptom management. Allergy medicines such as decongestants and antihistamines can be taken at the start of an allergy attack to prevent the development of sinusitis, but once sinusitis develops further treatment is necessary.
It may be true that Nasal allergies cause nasal itching and sneezing, runny nose, nasal stuffiness and postnasal drainage. These symptoms are similar to those of sinusitis. Most experts believe nasal and sinus swelling from allergies can contribute to the development of sinusitis. However, other factors, such as chronic infection, also contribute significantly to the development of chronic sinusitis.
It is important to distinguish the allergies from sinus infection. An ordinary sinus allergy may lead to a more serious and fatal infection such us chronic sinusitis. Diagnosis is important in able to prevent it from becoming a major problem to your life.
