Substances that are in the air such as pollen, pet dander (which is what causes people to be allergic to dogs and/or cats), dust mites, and mold will often cause a stuffy nose, coughing and sneezing. Bee or wasp stings will cause swelling, pain, itching, and in extreme cases, possibly anaphylactic shock. Foods such as peanuts, other nuts, wheat, soy, fish, shellfish, eggs, milk may cause digestive problems like nausea, vomiting, or diarrhea or even anaphylactic shock.

If you have suspicion of what you might be intolerant to, eliminate it from your diet. If that was the source, your symptoms should improve. Your doctor may ask you to eat it again, to see if your symptoms return. This would help confirm that it was the source.

The doctor will expose you to the allergen to decrease your reaction to it. Each dose you get will be greater than the last until you reach a maintenance dose. The allergens are usually administered as shots, but for grass and ragweed, you may get a pill that will dissolve under your tongue. Many allergists also offer immunotherapy in the form of drops that you put under your tongue. This must be done under a doctor’s supervision and may take several years.

Carpets, in contrast to hard floors, hold allergens and pet dander, making it more difficult to keep the house allergen-free. Wash your bedding regularly. You spend about a third of your day in bed. If you have allergens on your sheets and pillow, you are spending a third of your time breathing in those allergens. Use a dust mite cover on your mattress to prevent allergens from settling. Wash your hair before you go to bed to rinse out any pollen that might be stuck in it. If you are allergic to particular pollens, stay at home as much as you can at the time of the year when the levels of those types of pollen are high. Keep your windows closed to prevent pollen from blowing into your house.

Keep your home dry using fans and dehumidifiers in rooms with high humidity, like the bathroom. Fix any leaks in your house.
