While many people associate allergies with childhood, a large number of adults suffer from allergic reactions. Some adults may even need to seek the assistance of a medical professional in treating the symptoms of allergic reactions. The most common sources of adult allergies result from a wide variety of sources.

Pollen ranks as one of the top allergens in the world. Trees, grasses, and flowers contribute to the release of pollen in the air. In many areas, the telltale yellow residue on the ground indicates that the pollen season is in full swing. When this occurs, allergy sufferers should initiate preventative measures. Pollen allergies normally impact the sinuses and respiratory tract causing congestion, runny noses and sneezing.

Dust, one of the most common substances on the planet, causes a significant amount of allergies. Dust mites produce substances that trigger reactions. The most common reactions are sneezing and a runny nose. The next time you see the dust accumulating on the ceiling fan (or anywhere else), you should clean it to reduce exposure to this allergen.

Many adults suffer from food allergies. Foods that cause allergic reactions include tree nuts (such as walnuts, almonds, and cashews), milk, soy, shellfish, non-shellfish seafood, and peanuts. The allergies can be triggered by exposure to the food as part of a recipe.

For example, while eating nuts alone can trigger an allergy, eating nuts added to the main course or dessert, and which are not immediately evident from looking at the meal, can still trigger allergic reactions. People susceptible to food allergies should ensure that they know what is in the food they purchase and warn anyone who prepares their food for the allergy.

Medication, especially penicillin, can cause allergic reactions in adults. Penicillin remains one of the medications most likely to cause allergic reactions in patients. Your medical professional should be advised of any medication allergies prior to prescribing drugs and any adverse reactions should be immediately reported to a pharmacist or the prescribing physician.

Insect bites and stings, such as those from bees, wasps, and ants, also trigger allergic reactions in adults. The reactions range from mild swelling to anaphylactic shock. Anyone who has experienced such a reaction should be careful working in gardens or outdoors where such insects may reside and should also be careful when in the wilderness, such as camping or on hikes.

Finally, man’s best friends —- cats and dogs —- occasionally, and unintentionally, trigger allergic reactions in their humans. Pet hair and dander can trigger a host of allergic reactions but most commonly runny noses, sneezing, and watery eyes.

These are the most common adult allergies, however, other substances also cause allergic reactions. If you experience allergic reactions you should seek the assistance of a medical professional to determine the source of the reaction and the appropriate treatment.
