  I had acid reflux so bad for a year that my esophagus stayed inflamed, I was given things by the doctors and told to raise the head of my bed as I would inhale the acid in my sleep and wake up choking! I got tested with the Symptom Survey Analysis, started taking the Standard Process supplements.....

One evening after eating pizza, I had terrible indigestion and a lot of pain in my upper right back. I had this before and after a previous ultrasound, knew I had several gallstones, so I was sure it was my gallbladder acting up again. I figured I had overdone it, so I was careful with what I ate, but a dull pain stayed with me for five more days. I thought it was finally better, but only one day went by without pain....

How does a simple substance like a grain of pollen lead to runny noses and teary eyes? Click above to find out what happens when your body meets an allergen.

 

From sneezing and wheezing to itching and tearing, allergies and asthma affect as many as 60 million people in the United States (more than 20 percent of the population). When your body reacts to what is normally a harmless substance, it "attacks" the allergen with a fusillade of weapons. The results can range from mild congestion to death. A little bit of education and effort, however, can go a long way to making your life free of allergic symptoms and asthma attacks.

An allergy is an inappropriate response by the body's immune system to a substance that is not normally harmful. There are many types of allergies, including food allergies, ragweed, pollen, mold spores, animal hair, and certain metals.

Ever wonder what's going on inside your body when you have an allergic reaction? Come inside with us and take a look.

 

Nasal Allergies

Nasal allergies refer to the interaction of allergens with cells within the lining of the nose.

What is going on in the body?

Allergens enter through the nose. Allergens include pollens, dust, dust mites, mold spores, and animal dander. These substances interact with IgE antibody on the mast cells inside the nose. This causes discharge of histamine. Histamine causes sneezing, nasal congestion, and nasal discharge.

The mast cells also release other substances. These substances pull a group of cells, called eosinophils, into the nasal lining. The eosinophils travel into the lining of the nose over a 6- to 24-hour period. They then release substances that can create additional symptoms hours after the original exposure.

The first reaction is called the early reaction. The symptoms occurring hours after the initial exposure make up the late-phase reaction.

For example, an individual who is sensitive to cats will develop an immediate allergic reaction when exposed to a cat. This initial acute attack may continue as long as the individual is exposed. Once the person leaves the environment, the symptoms subside. Later, the release of eosinophils may bring on another wave of the symptoms.
