Overview

There’s a reason the local news provides regular updates on pollen counts each spring: Tens of millions of Americans sufferAllergies are inappropriate or exaggerated reactions of the immune system to substances that, in the majority of people, cause no symptoms. Symptoms of the allergic diseases may be caused by exposure of the skin to a chemical, of the respiratory system to particles of dust or pollen (or other substances), or of the stomach and intestines to a particular food." rel="tooltip">allergy由接触引起的症状树,草和小d pollens.

Pollen is a fine yellowish powder that is transported from plant to plant by the wind, by birds, by insects or by other animals. The spread of pollen helps to fertilize plants — and can mean misery for seasonal allergy sufferers.

Trees, grass or weeds making you sneeze and wheeze?

It’s time for an allergist.

Symptoms

If you have a pollen allergy and breathe in pollen-heavy air, you may experience symptoms such as:

  • Sneezing
  • Nasal congestion
  • Runny nose
  • Watery eyes
  • Itchy throat and eyes
  • 喘息

Pollen can also aggravateAsthma is a chronic, inflammatory lung disease characterized by recurrent breathing problems. People with asthma have acute episodes where the air passages in their lungs get narrower, and breathing becomes more difficult. Sometimes episodes of asthma are triggered by allergens, although infection, exercise, cold air and other factors are also important triggers." rel="tooltip">asthmasymptoms, including increased coughing and wheezing.

Management and Treatment

Find an allergistto pinpoint the cause of your symptoms and help you find relief.

One key tip is to get ahead of pollen season. For example, if your symptoms are typically at their worst in mid-April, start taking your medications at the end of March. Likewise, if the weather calls for a run of warm weather toward the end of winter, it might be smart to begin taking your medication at that time as well. Ask your allergist about medications that can be taken in advance of pollen season.

TwoImmunotherapy is a form of preventive and anti-inflammatory treatment of allergy to substances such as pollens, house dust mites, fungi, and stinging insect venom. Immunotherapy involves giving gradually increasing doses of the substance, or allergen, to which the person is allergic. The incremental increases of the allergen cause the immune system to become less sensitive to the substance, perhaps by causing production of a particular "blocking" antibody, which reduces the symptoms of allergy when the substance is encountered in the future." rel="tooltip">immunotherapyoptions are available for those with severe pollen allergies:

  • Allergy shots can help your body build resistance to pollens.
  • Tablets that dissolve under the tongue are now available by prescription for people suffering from grass and ragweed allergies. These medications must be started 12 weeks before symptoms are expected to begin.

Pollen Counts: Not Always the Full Story

It’s a good idea to keep an eye on the predicted pollen counts, particularly if you plan to be outdoors for a long period of time. (If you are planning to be outside working around plants or cutting grass, a dust mask can help.)

But even if you see a high pollen count predicted in the newspaper, on a smartphone app or on TV, it doesn’t necessarily mean thatyouwill be affected. There are many types of pollen — from different kinds of trees, from grass and from a variety of weeds. As a result, a high overall pollen count doesn’t always indicate a strong concentration of the specific pollen to which you’re allergic.

The opposite can be true, too: The pollen count might be low, but you might find yourself around one of the pollens that triggers your allergies.

Through testing, an allergist can pinpoint which pollens bring on your symptoms. An allergist can also help you find relief by determining which medications will work best for your set of triggers.
