Um, not really.
Allergies and Asthma are really the same thing. I just read about this recently. Also, there's still a great deal doctor's don't know about allergies, partly they are difficult to study.
Reactions can occur in the stomach, the lungs, one's skin (hives), etc. Very often they overlap. People with severe food allergies often have trouble breathing while vomiting. What's scary is that reactions often change from exposure to exposure. It often depends on the level of exposure.
Allergies typically involve a protein; just about any protein.
However, each person has a different threshold. Person A might develop a reaction at the slightest hint of a substance, but person B only reacts when a larger amount of that substance is present. (Pollen allergies are a great example, because many folks only react when pollen counts are very HIGH.)
Another scary aspect of allergies is that the severity of increases dramatically when multiple allergens are present together. Say, smoke by itself triggers a mild reaction, but smoke + pollen together= anaphylactic shock.
They are not the same thing. Stay off of WebMD. LOL
I have studied this (I have a niece with severe pulmonary issues), so I am going to share some basic notes with you that are readily available to anybody who wants to research.
The primary difference between an allergy attack and an asthma attack is the location in the body of the reaction. Allergens – substances such as pollen, dust, and mold that are not harmful in themselves but result in a reaction in those allergic to them – often trigger this response in the upper respiratory system. The reaction happens because your body produces IgE (immunoglobulin E) antibodies, which in turn cause the body to produce chemicals like leukotrienes and histamines. These chemicals trigger the allergic reaction itself, which is commonly experienced as sneezing, congestion, itching, watery eyes, hives, headaches, or irritated skin.
Asthma is a more serious condition. It can be triggered by the same IgE antibodies, but the reaction is located in the lungs and upper bronchial passages. They may become inflamed and close down, causing coughing or wheezing. During an asthma attack the bands of muscle surrounding your airways experience bronchiospasm, which causes them to narrow. The membranes that line these airways become inflamed, or swollen, and produce more mucus, further limiting the flow of air. This may be experienced as coughing and wheezing, as mentioned above, but can also cause chest pains, shortness of breath, and being unable to breathe. Asthma affects more than 25 million people around the world, and is the most common chronic disease found among children. 5,000 people per year die of asthma.
