Asthma: Treatment, Diagnosis and Prevention



Asthma

What Is Asthma?
A person with asthma has fits or attacks of difficulty breathing, Listen for a hissing or wheezing sound, especially when breathing out. When he breathes in, the skin behind his collar bones and between his ribs may suck in as he tries to get air.


Asthma cough

If the person cannot get enough air, his nails and lips may turn blue, and his neck veins may swell. Usually there is no fever.
Asthma often begins in childhood and may be a problem for life. It is not contagious, but is more common in children with relatives who have asthma. It is generally worse during certain months of the year or at night.
An asthma attack may be caused by eating or breathing things to which the person is allergic.
Asthma (AZ-ma) is a chronic (long-term) lung disease that inflames and narrows the airways. What can leads to Asthma:

The coughing often occurs at night or early in the morning.
Asthma affects people of all ages, but it most often starts during childhood.
Statistics
In the United States, more than 25 million people are known to have asthma. About 7 million of these people are children.
Asthma is a respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing. It usually results from an allergic reaction or other forms of hypersensitivity.
Asthma is a chronic disease involving the airways in the lungs. These airways, or bronchial tubes, allow air to come in and out of the lungs.
To understand asthma, it helps to know how the airways work. The airways are tubes that carry air into and out of your lungs. People who have asthma have inflamed airways. The inflammation makes the airways swollen and very sensitive. The airways tend to react strongly to certain inhaled substances.
When the airways react, the muscles around them tighten. This narrows the airways, causing less air to flow into the lungs. The swelling also can worsen, making the airways even narrower. Cells in the airways might make more mucus than usual. Mucus is a sticky, thick liquid that can further narrow the airways. This chain reaction can result in asthma symptoms. Symptoms can happen each time the airways are inflamed.

Causes of Asthma                                                                   
Understanding the experiences or exposures that make your asthma flare-up is a key step to better managing your asthma. Making a plan to avoid or limit your exposure to your asthma triggers can eliminate asthma symptoms and put you on the right track to better control your asthma. These factors play an important role in the development of asthma.
Asthma could be triggered by these factors:
Asthma triggers are different from person to person and can include:

Symptoms/Signs of Asthma                                               
The most common symptom is wheezing. This is a scratchy or whistling sound when you breathe. Other symptoms include:

How to diagnose Asthma
The two most common lung function tests used to diagnose asthma are

Spirometry is a simple breathing test that measures how much and how fast you can blow air out of your lungs. It is often used to determine the amount of airway obstruction you have.
These Are Common Ways to Diagnose Asthma
Personal and medical history:  Your doctor will ask you questions to understand your symptoms and their causes. Bring notes to help jog your memory. Be ready to answer questions about your family history, the medicines you take and your lifestyle. This includes any current physical problems. Shortness of breath, wheezing, coughing and tightness in your chest may show asthma. This also includes all previous medical conditions. A history of allergies or eczema increases your chance of asthma. A family history of asthma, allergies or eczema increases your chance of having asthma, too. Tell your doctor about any home or work exposure to environmental factors that can worsen asthma. For example, these might include pet dander, pollen, dust mites and tobacco smoke. The doctor may also ask if you get chest symptoms when you get a head cold.
Physical examination: If your doctor thinks you have asthma, they will do a physical exam. They will look at your ears, eyes, nose, throat, skin, chest and lungs. This exam may include a lung function test to detect how well you exhale air from your lungs. You may also need an X-ray of your lungs or sinuses. A physical exam then allows your doctor to review your health.

Lung function tests: To confirm asthma, your doctor may have you take one or more breathing tests known as lung function tests. These tests measure your breathing. Lung function tests are often done before and after inhaling a medication known as a bronchodilator (bron-co-DIE-a-later), which opens your airways. If your lung function improves a lot with use of a bronchodilator, you probably have asthma. Your doctor may also prescribe a trial with asthma medication to see if it helps. Common lung function tests used to diagnose asthma include:
Testing airway inflammation

  It may also be useful in some cases to carry out tests to check for inflammation in your airways. This can be done in two main ways:

Spirometry: This is the recommended test to confirm asthma. During this test, you breathe into a mouthpiece that’s connected to a device. It is called a spirometer. The spirometer measures the amount of air you’re able to breathe in and out and its rate of flow. You will take a deep breath and then exhale forcefully. 
Peak airflow: Peak expiratory flow test a small hand-held device known as a peak flow meter can be used to measure how fast you can blow air out of your lungs in one breath. This is your peak expiratory flow (PEF) and the test is usually called a peak flow test.
This test requires a bit of practice to get it right, so your GP or nurse will show you how to do it and may suggest you take the best of two or three readings.
You may be given a peak flow meter to take home and a diary to record measurements of your peak flow over a period of weeks. This is because asthma is variable and your lung function may change throughout the day.
Your diary may also have a space to record your symptoms. This helps to diagnose asthma and, once diagnosed, will help you recognize when your asthma is getting worse and aid decisions about what action to take.
To help diagnose asthma that may be related to your work (occupational asthma), your GP may ask you to take measurements of your peak expiratory flow both at work and when you are away from work. Your GP may then refer you to a specialist to confirm the diagnosis.
Trigger tests: If your other results are normal, but you’ve been experiencing signs and symptoms of asthma, your doctor may use known asthma triggers to try and provoke a mild reaction. If you don’t have asthma, you won’t react. But if you do have asthma, you likely will develop asthma symptoms.
How to Prevent Asthma
A person with asthma should avoid eating or breathing things that bring on attacks. The house or work place should be kept clean. Keep chickens and other animals outside.
Air bedding in the sunshine, Sometimes it helps to sleep outside in the open air. Drink at least 8 glasses of water each day to keep the mucus loose.

Chalk dust can trigger an asthma attack - so it may be helpful for your child to sit away from chalkboards in class. His or her coaches and/or physical education teacher can provide important information about asthma symptoms during exercise.

Treatment for Asthma
Asthma treatment can vary from anti-inflammatory and bronchodilator asthma inhalers to oral medications to asthma drugs delivered in an asthma nebulizer or breathing machine. Get a better understanding of how asthma medications work so you'll know which medications can prevent asthma symptoms. Also, learn about natural asthma remedies and ways to monitor your breathing at home.
The types and doses of asthma medications you need depend on your age, your symptoms, the severity of your asthma and medication side effects.
Because your asthma can change over time, work closely with your doctor to track your symptoms and adjust your asthma medications, if needed.

There are two types of asthma medicines: long-term controllers and quick-relievers. The difference between these can be confusing. That’s why you need to understand what each type of medicine does and how they help your asthma. It’s also important to learn how to use each medicine correctly. Always take your medicines and follow your health care provider’s instructions.
Long-Term Control Medicines
Long-term control medicines help you prevent and control asthma symptoms. You may need to take this type of medicine every day for best results. There are several kinds of long-term control medicines:
Inhaled corticosteroids prevent and reduce airway swelling. They also reduce mucus in the lungs. They are the most effective long-term control medicines available. Corticosteroids are not the same as anabolic steroids that are taken by some athletes and banned in many athletic events.
Inhaled long-acting beta agonists open the airways by relaxing the smooth muscles around the airways. If used, this type of medicine should always be taken in combination with an inhaled corticosteroid.
Combination inhaled medicines contain both an inhaled corticosteroid and a long-acting beta agonist. If you need both of these medicines, this is a convenient way to take them together.

Quick-Relief Medicines
You use quick-relief medicines to help relieve asthma symptoms when they happen. These medicines act fast to relax tight muscles around your airways. This allows the airways to open up so air can flow through them. You should take your quick-relief medicine when you have asthma symptoms. If you use this medicine more than 2 days a week, talk with your doctor about your asthma control. You may need to make changes to your treatment plan.
Short-acting beta agonists are inhaled and work quickly to relieve asthma symptoms. These medicines relax the smooth muscles around the airways and decrease swelling that blocks airflow. These medicines are the first choice for quick relief of asthma symptoms.
Anticholinergics are inhaled but act slower than the short-acting beta agonist medicines. These medicines open the airways by relaxing the smooth muscles around the airways. They also reduce mucous production.
Combination quick relief medicines contain both an anticholinergic and a short-acting beta agonist. This combination comes either as an inhaler or nebulizer for inhalation.
