Many people are born with allergies to specific trigger substances and they suffer with the effects for most of their lives. Allergic reactions are a hyper-sensitivity to these substances, which cause the body to react as if they are foreign invaders. This leads to the unfortunate and irksome itching of the eyes, the scratchy throat, and unsightly skin conditions. With symptoms like these, allergy sufferers know all too well the importance of being free of their trigger substances. Fortunately, most allergy sufferers eventually come to know what it is that they're allergic to should these symptoms surface.

But there are some who may become allergic to a trigger (or triggers) and simply never understand what's happening to them. These people then come to deal with the frustrations of allergies with no knowledge of their issues and no seeming end in sight.

As we age, people who had previously been allergy-free can develop allergies to any substance that they have been exposed to daily. This development is compounded by the fact that with each day that passes, countless allergens are being introduced and then circulating and accumulating in the home.

If someone in your home has suddenly been experiencing headaches, itchy eyes and/or throat, coughing, sneezing, a blocked nose, skin conditions, or swelling of the tongue, lips, or eyes, they may have developed a hyper-sensitivity to a trigger substance. From mold and pet dander to dust mites and cockroaches, these hidden triggers could be the cause of the troublesome health issues.
