**SayPro Different types of asthma
Asthma causes the airways to become inflamed and swollen, reducing the amount of air that can pass in and out of the lungs. However, there are several different types of asthma, and each has its own set of triggers.
Certain allergens in the environment can trigger allergic asthma. Some common allergens include:
pollen
pet dander
mold spores
foods such as milk, eggs, and certain nuts
dust mites, cockroaches, and cockroach feces
irritants in the air, such as tobacco smoke and automobile and chemical fumes
heavily fragranced products, such as perfumes
Treatment
It is important for people with allergic asthma to seek treatment from a specialist, as this can help them manage their condition. They should also take any prescribed medication as a specialist directs.
The following tips may also help people with allergic asthma avoid common allergens:
Vacuum and dust regularly in order to remove pet dander, dust mites, and cockroach allergens.
Keep pets out of bedrooms.
Avoid outside activities when pollen or air pollution levels are high.
Avoid foods that trigger allergic reactions, such as milk, eggs, shellfish, peanuts, and tree nuts, including hazelnuts, walnuts, and almonds.
Reduce the use of harsh chemicals or heavily fragranced products at home.
Nonallergic asthma
Nonallergic, or intrinsic, asthma does not require an allergen to trigger an attack.
It is less common than allergic asthma, accounting for around 10–33% of all asthma cases. It is more likely to appear in adulthood and affects more females than males.
Experts believe that nonallergic asthma develops due to genetic and environmental factors.
For example, symptoms may occur when a person has exposure to:
cold
humidity
stress
exercise
pollution
irritants in the air, such as smoke
respiratory infections, such as a cold, flu, or sinus infection
Treatment
People with symptoms such as shortness of breath, wheezing, or coughing should seek help from an asthma specialist. This will help them determine what is triggering their symptoms. However, it may take longer to work out what is causing nonallergic asthma.
To manage their symptoms, they should also take any prescribed medication as a specialist directs.
Seasonal asthma
In seasonal asthma, symptoms flare up in certain conditions or at particular times of the year.
For example, a person with seasonal asthma may notice that symptoms are worse, or only present, during:
hay fever season, when pollen levels are at their highest
cold or hot weather, thunderstorms, and sudden changes in temperature
days when air pollution is worse, such as still, cold days
winter months, when there are more cold and flu viruses around
In many ways, seasonal asthma is similar to allergic asthma. In fact, people may use both terms to describe asthma attacks that occur during the pollen season.
Treatment
People with seasonal asthma should seek medical treatment. This will help them manage their condition during periods when symptoms are likely to get worse.
They should also take any prescribed medication as a doctor or healthcare provider directs.
The following tips may also help reduce symptoms of seasonal asthma:
Pay attention to local weather reports on air quality and pollen levels, and only plan outside activities for when conditions are less likely to trigger an asthma attack.
Keep windows and doors closed, both at home and when traveling by car.
Wear a scarf over the mouth and nose in cold weather, to warm up air as it passes into the lungs.
Keep medication on hand for quick relief from symptoms.
Keep a diary to note which weather conditions seem to bring on symptoms.
Occupational asthma
People with occupational asthma may find that their symptoms are worse while working, or that they improve with time off work.
In fact, up to 15% of asthma cases in the U.S. may be due to job-related exposure to paint chemicals, aerosols, insecticides, or other harmful substances.
How long the symptoms take to occur may depend on the level of exposure to these and other substances. Some people may have an asthma attack within 24 hours of exposure. In others, it may take months, or even years, for any symptoms to develop.
Treatment
People with occupational asthma should seek treatment from a doctor or healthcare provider. This will help them identify what is causing their symptoms, avoid further exposure, and ease their symptoms.
They should also take any prescribed medication as a doctor or specialist directs.
Exercise-induced asthma
Exercise-induced asthma occurs when symptoms flare up during or immediately after exercise or another form of strenuous activity. This may happen around 5–20 minutes after the exercise.
Although it is common to experience shortness of breath after exercise, exercise-induced asthma may also cause coughing, wheezing, and chest pain, ranging from mild to severe.
Around 90% of people with asthma also experience exercise-induced asthma, with the majority of cases having a mild form that responds well to treatment.
The following factors may also worsen symptoms of exercise-induced asthma:
chlorinated pools
exposure to polluted air while running or cycling outside
cold, dry air while ice skating or playing hockey
warm, humid air while doing hot yoga
Treatment
Asthma medications can often treat the symptoms effectively. However, it is important for people to see a doctor if their symptoms are not responding to regular medication.
The following tips may also help reduce the risk of an asthma attack during or after exercise:
Use an inhaler before exercise and keep it close to hand when exercising.
Avoid exercising with a viral infection.
Warm up before exercise, to help loosen the airways.
Cool down after exercise, to help breathing slow gradually.
Wear a scarf over the nose and mouth when exercising outdoors.
Avoid exercises that result in labored or heavy breathing.
