Both researchers and doctors believe that one of the causes of nasal polyposis is a chronic allergic state. This condition, coupled with postnasal drip, could well be responsible for your hoarseness. A com­plete allergic survey should be made, followed by therapy.

Evidence is increasing that various weather phenomena, including changes in barometric pressure, have a significant effect on human health. With regard to your particular problem, it is best to seek a physician’s advice and help in administering nasal decongestants when the weather changes, to minimize the effects of the changes.

Allergy could indeed be causing you to lose your sense of smell. If all other possible causes have been eliminated, an allergic survey is needed. This survey, which may include skin tests, may be able to identify the external substances to which you are allergic. It is possible that a specific treatment will be prescribed, based on the information turned up by the survey.
