Types of asthma
Depending upon various aspects of severity,
chronicity seasonal variation and predominant
aggravating factors asthma is classified in to
various types. |
Seasonal Asthma
This occurs only during a specified season of the
year (often due to pollen, spores, or climate). |
Perennial Asthma
Continues round the year |
Atopic or extrinsic Asthma
Also known as allergic or extrinsic asthma.
Patients of this category usually suffer from
some other allergic disease such as skin allergy,
eye allargy or nose allergy. Asthma of this
nature gets aggravated by allergic agents. |
Non Atopic asthma or Intrinsic Asthma
Also called non allergic asthma. Patients of this
category do not have any other allergic disease
and their asthma is usually not aggravated by
allergic triggers.
|
Some other types
of asthma are:
 | Exercise induced asthma |
| Occupational asthma |
| Nocturnal asthma |
For some people with asthma, asthma attacks have nothing
to do with allergies. Although these people get the same
symptoms and have the same changes in their airways as
patients with allergic asthma, their asthma is not
triggered by allergies. However, like any patient with
asthma, asthma attacks may be triggered or made worse by
one or more non allergic asthma triggers including
materials (irritants) in the air you breathe, such as
tobacco smoke, wood smoke, room deodorizers, pine odors,
fresh paint, household cleaning products, cooking odors,
workplace chemicals, perfumes, and outdoor air pollution.
Respiratory infections, such as the common cold, the flu,
or a sinus infection may also give you symptoms. Finally,
exercise, cold air, sudden changes in air temperature and
even gastroesophageal reflux (heartburn) may be triggers
for people with non-allergic asthma.
