You have probably experienced the upper respiratory or skin symptoms of an allergic reaction at some point in your life. In fact, an estimated 1 in 3 people suffer from allergies. Sometimes, your allergies can be so frequent and draining that you require allergy shots to help you get through your day. Although everything from food to insect bites can stimulate an allergic reaction, one of the most common causes of allergies are airborne particles.
First, it is important to understand why allergies occur. Essentially, an allergic reaction is solely the result of your immune system’s overreaction to a common, non-harmful item. The immune system is “plastic,” or easily adaptable. As you encounter pathogens, your immune system develops antibodies to recognize and attack these invaders. Sometimes, though, these antibodies can be targeted to regular things in your environment, such as dust. Then, every time you encounter dust, your antibodies attack.
When your immune system believes it is under attack, it releases many chemicals such as histamine into your body. Normally, these chemicals help you fight a true invader. However, if your body is not actually under attack, the histamine can cause the painful, irritating symptoms of an allergic reaction. Common airborne particles that can be mistaken for invaders include:
-Dust mites -Animal dander -Mold spores -Pollen -Air pollution
As your immune system overreacts to one of these substances, you can suffer from a debilitating allergic reaction. Normally, airborne allergens affect your upper respiratory system as this is where you are first exposed to the particles. You can develop symptoms such as:
-Runny nose -Red, itchy eyes -Watery eyes -Congestion -Sneezing -Scratchy throat -Itchy nose
Allergies can make you feel miserable. If your symptoms are frequent and severe, you may want to take allergy shots in order to help reduce your immune system’s response to airborne allergens. However, it can be difficult and costly to seek this medical care every two to four weeks. Thankfully, though, you can find a health insurance plan that fits your needs.

If you are allergic to a pollen you may be allergic or react to certain foods such as apples, celery, nuts, melons or bananas. Numerous studies have confirmed the reports of people who have pollen allergies reacting to certain foods. The most well described and studied of the food-pollen syndromes is the oral allergy syndrome (OAS) or as it is also called “the burning mouth syndrome” because of the typical reaction noted by affected people. After eating a food that cross reacts with a pollen to which you are allergic, burning or tingling sensations begin in your mouth. Itching, pain, swelling and difficulty swallowing or breathing may occur. True anaphylaxis resulting in total body collapse from shock and death if not reversed has rarely been reported.
Typical pollen allergy symptoms such as runny nose and congestion, itchy watery eyes, and wheezing are also commonly reported. Other symptoms described include nausea, stomachaches, headaches, diarrhea and chest or throat tightness. Very few people are aware of these associations. Most doctors, except a few allergists and gastroenterologists, do not explore patients allergy history in the context of possible food reactions. Educating people about these types of conditions is one of the primary goals of “the food doc”, Dr. Scot Lewey, a practicing gastroenterologist (stomach-intestine specialist).
Ragweed pollen has been shown to be associated with these type of reactions after people eat bananas and fruits in the gourd family such as watermelon, honeydew, and cantaloupe. Pollen from Mugwort, another weed also known as Sagebrush, in the Artemisia family, has been associated with allergic reactions to celery, carrots, fruits in the Rosaceae family (apples, cherries, peaches) and those in the Gourd family (melons). Pistachio, persimmon, peanuts, almonds, sunflower seeds, hazelnuts, lettuce, camomile tea, and honey have also been reported to cause reactions in some people who are Mugwort pollen allergic.
Birch tree pollen is associated with numerous food cross reactions including celery. Cross-reactivity between celery and Birch pollen occurs more in central Europe whereas in Southern Europe celery and Mugwort reactions are more common. A Mugwort-Birch-Celery-Spice syndrome has also been described. People allergic to both Birch tree and Mugwort weed pollen may react to spices like pepper and paprika in addition to celery, carrot, and mango. Birch pollen is strongly associated with food reactions to Rosaceae family fruits (apples, apricots, peaches, pears, cherries), tree nuts (walnut, hazelnut, Brazil nut), legumes (peanut, various beans and peas), members of the Parsnip family (parsnip, parsley, anise, cumin, caraway, coriander) and the potato-nightshades (potato, tomato, peppers).
House dust mite, a serious allergen for many people, cross reacts with mangos, shellfish, bananas, melons, tomato, avocado, papaya, pineapple, peaches, Kiwi fruit and various spices. Kiwi, an unusual fruit in a class by itself, may elicit a reaction in people allergic to Birch trees, Mugwort weed pollen, and latex. The Latex-Fruit Allergy Syndrome is characterized by allergy to foods in the Rosaceae family including almond (classified as a fruit not a nut) and plums, as well as other fruits such as passion fruit, papaya, pineapple, mango, melons, and bananas. It is also associated with reactions to spices such as dill, ginger, and oregano and the nightshades, potato and tomato and chestnuts.
A few articles in scientific literature have reported associations of specific HLA gene patterns to pollen allergy and fewer still have noted HLA DR and DQ gene pattern associations with food-pollen cross-reaction syndromes. HLA DQ genetics are well known in celiac disease. There is also limited published data associating certain DQ patterns with microscopic colitis, collagenous colitis and non-celiac gluten sensitivity. HLA typing may be clinically useful in evaluation and elimination diet recommendations for suspected food allergic, intolerant or sensitive individuals. This type of information will be one of the goals of thefooddoc.com website. A table that lists the common pollens and foods that have been reported to cross-react with those pollens will be posted on the site very soon.
Though extensive research has been done and many of the protein structures contributing to these cross-reactions is known, little is known about these reactions by most of the lay public and many doctors. Seasonal pollen allergies may be associated with more severe reactions. Those with documented cross-reactions or prior OAS reactions may be at increased risk and certain HLA gene or DQ patterns may be associated. People with known or suspected pollen allergies should be aware of these possible food reactions.

Pollen allergies develop in humans due to the natural reproduction for plants which is done through pollination with the help of the wind. Often, pollen allergies are referred to as ‘hay fever’ because people noticeably suffer from them during haying season, but a pollen allergy can happen in spring, summer or fall because various plants pollinate at different times of the year. Symptoms can vary depending on general climate and how severe the reaction is to different types of pollen. Pollen allergies can be difficult to identify because the symptoms are very similar to other types of allergy symptoms like those that are noted with pet dander and mold.
Generally, the symptoms of pollen allergies include itchy eyes and skin, a stuffy nose with the possibility of nosebleeds. Sometimes this leads to trouble breathing. Often headaches are included in the list of symptoms, as are sore throat and dark circles under the eyes. Symptoms can also include coughing and wheezing as well as asthma attacks. Increased congestion is a frequent symptom, along with sneezing and runny nose. Feeling tired and weak or drowsy is one of the more common symptoms. However, sometimes food allergies are mistaken for pollen allergies.
Some of the differences include rashes and hives in food allergies in addition to itchy skin, or not just sneezing, but watery eyes and an itchy throat at the same time. Food allergies can also cause nausea, burping, vomiting or diarrhea, where usually pollen allergies do not. Sometimes food allergies increase allergic asthmatic reactions to dust and mold and make them worse without the symptoms being obvious right after eating the food.
Pollen allergies are the main allergies in the United States, especially during the seasonal allergy months, which are spring and summer. Wintertime is usually less of a problem for allergy sufferers, but there are still some plants that release pollen in the middle of winter. Because the symptoms often mimic other types of allergies, it is a good idea to visit a doctor to determine exactly what kind of allergy you are suffering from so that you can get proper treatment. Though you may want to, you really can’t diagnose yourself, and may try to treat one allergy with the remedy for another, which usually doesn’t work. All in all, pollen allergies are suffered by many people, and there are various effective treatments to help, but you should visit an allergy specialist to be evaluated and properly treated for the specific type of allergy you may have.
Generally, allergy shots are safe, with minimal side effects. There are no long-term complications associated with this form of therapy, but there is a small risk of allergic reactions immediately following the injection. These allergic reactions can be severe.
Typically, allergy shots may cause slight swelling or redness at the injection site. These reactions can occur immediately after the injection and/or can occur several hours later. This mild allergic reaction is usually harmless and goes away within 24 hours.
The shots may also cause symptoms similar to the allergy symptoms you experience: itchy, stuffy nose; itchy, watery eyes; sneezing. In very rare cases, these symptoms become very severe and are accompanied by other symptoms, including the following, difficulty breathing or wheezing, chest or throat tightness, rapid or irregular heart beat, dizziness or light-headedness, loss of consciousness and death.
This type of very severe allergic reaction is known as anaphylaxis. It is a very uncommon reaction to an allergy shot, but it is dangerous, even life threatening.
This is less likely to happen if you follow the schedule of shots recommended by your allergist and observe the technician administering the shot. Be sure you are receiving the correct dose of the correct extract. The dizziness, light-headedness, and loss of consciousness are due to dangerously low blood pressure, usually called “shock.” These symptoms occur when the brain is not receiving enough blood. Anaphylactic shock is a medical emergency.
Such severe reactions usually begin within 20-30 minutes after receiving the shots. For this reason, most allergists require that you wait in the office for 20-30 minutes after your shots to be monitored. If you should experience these symptoms at any time, tell the allergist or other medical professional right away.
If you have already left the allergist’s office, and are having a severe reaction, go directly to the nearest hospital emergency department. If you already have and Epi-pen, use it. If you have an antihistamine such as Benadryl, take it regardless, go to the nearest hospital emergency room or urgent care center as soon as possible. Do not attempt to drive yourself. If no one is available to drive you immediately, call 911 for emergency transport.
Immunotherapy does not treat symptoms; it treats the immune system, the source of all allergic reactions. Although the exact details of how allergy shots work is unknown, we do know the general way they affect the immune system.
An allergic reaction occurs when the body is exposed to an external substance (the antigen) that the immune system interprets as a foreign invader. In allergic individuals, the immune system then makes an unusual (allergic) response that harms the body.
Allergy shots desensitize you by turning down this immune response to the antigen. As a result of immunotherapy, the white blood cells no longer respond as strongly to the antigen, and less production of the immunoglobulin E antibody to this antigen occurs. So, when you are exposed to this antigen, less severe allergic reactions occur in affected areas like the eyes, nasal mucosal surfaces, and the bronchial airways.
Every year millions of Americans suffer from seasonal allergy. However, a certain percentage of those who suffer from seasonal allergies dismiss it as chronic cold. To better understand this, we need to define and differentiate it from the common cold.
Unlike colds that occur during winter or usually when there is a sudden change in temperature, allergies are caused by allergens. This causes an allergic reaction on the bodily function of a human sensitive to that particular allergen which is not experienced by the average individual.
Allergic rhinitis can be classified as perennial and seasonal. Perennial allergies happen any time of the year as long as the individual is exposed to the allergen such as house dust mites and pet dander. Seasonal allergies on the other hand happen at the same time every year or during particular seasons, hence the term. These are caused by pollens of flowering plants which are transported thru the air during the process of pollination.
When a person has colds, he starts to sneeze then later begins to have runny and congested nose. Sneezing is less common after the initial phase. If one has allergies, symptoms happen at the same time. Sneezing is more frequent coupled with runny nose and watery eyes. Itching of the nose and eyes are particularly bothersome in allergies. In several cases though, this develops into allergic rhinitis and asthma. And unlike colds that usually last from 7 to 10 days, allergies continue until the person is no longer exposed to the allergen.
Ragweed allergy, also known as fall allergy or hay fever, is the most common seasonal allergy. This occurs from mid August until October. About 75% of allergic individuals develop become allergic to ragweed pollen. Ragweed thrives in vacant lots and roadsides. Studies also mentioned that that most of those allergic to ragweed also develop allergic reactions to other pollens. Thus it is not surprising that they develop allergic symptoms during spring and summer when pollen grains from flowering trees and grasses are present in the air.
The nasal discharge of people who have colds is usually yellowish which means that it is caused by an infection. Sometimes colds are also accompanied by fever. Those who suffer from seasonal allergies do not usually have fever, and since it is not caused by any viral or bacterial infection, the nasal discharge is clear and watery.
Whether the sickness is caused by a cold or is a sesonal allergy, it still takes a toll on one’s health. In both cases there is a loss in appetite and sleeping problems also occur that disrupts how a person conducts his normal activities. Prevention is still the cure. Proper information too helps in the diagnosis of the ailment so that the appropriate medication can be taken.
