Asthma Management

Asthma is a respiratory condition in which the airways of the lungs (breathing passages) narrow and swell, often in response to an allergen.

This disease affects people of all ages, but usually starts in childhood.

Air in the lungs travel through small airways called bronchial tubes. When the airways are clear, air moves in and out of the lungs easily. An asthma attack constricts the airways and interferes with the normal breathing process.

Signs and symptoms

The common signs and symptoms of asthma include:

• Frequent cough
• Wheezing sound heard during breathing
• Shortness of breath and coughing
• Feeling of tightness in the chest
• Pain in the chest

As people experience asthma attacks they learn to recognize specific triggers that contribute to these attacks and try to stay away from them. There are individual triggers for each person. Children exposed to certain triggers become highly sensitive which causes the lungs and airways to swell up and produce mucus. Some of the triggers include the common cold, weather changes, physical activity, and air pollutants such as smoke, dust mites, animal dander, and pollen.

Diagnosis

• Asthma can be difficult to diagnose. Your doctor will ask about the frequency of your symptoms and order some tests to rule out other conditions.
• A lung function test (spirometry) is done to measure the amount of air exhaled.
• Allergy skin testing may be helpful to identify allergens in people with asthma.
• In younger children the diagnosis is done based on the information provided about symptoms because lung function tests will be inaccurate before 6 years of age.

Treatment

You must know as much as you can about asthma, its triggers, and how to recognize and avoid them. Avoiding the triggers and with the right medication, an asthmatic can have a perfectly normal life.

Treatment of asthma includes prevention of symptoms and treatment of progressive asthma attacks.

Your allergist may also prescribe two main types of medications, long- term control medications and quick- relief medications.

• Long-term medications that can be taken every day help reduce airway inflammation and prevent the asthma symptoms.
• Quick-relief medications provide rapid relief from symptoms during an asthma attack.

Inhaled short- and long-term control medications are used by inhaling measured amounts of the medication through inhalation devices.

• The most common is the metered dose inhaler that uses a chemical propellant to carry the correct dose of medication out of the inhaler.
• Dry powder inhalers (DPIs) do not use propellants but need a stronger and faster inhalation.
• A nebulizer is a type of inhaler that delivers medications in a fine mist through mouthpieces or masks.

By visiting an allergist you can take control of your asthma and improve your quality of life.
