ASTHMA

ASTHMA

Asthma is a chronic disorder characterized by shortness of breath, wheezing, coughing and tightness of the chest.  It is a disease of the lungs. The airways of people with asthma are extra sensitive to the things they’re allergic to (called allergens) and to other irritating things in the air (called irritants).

Asthma symptoms start when allergens or other irritants cause the lining of the airways to swell (become inflamed) and narrow. The muscles around the airways can then spasm, (contract rapidly), causing the airways to narrow even more. When the lining of the airways is inflamed, it produces more mucus. The mucus clogs the airways and further blocks the flow of air. This is called an “asthma attack.”

Asthma affects people differently. Each individual is unique in their degree of reactivity to environmental triggers. This naturally influences the type and dose of medication prescribed, which may vary from one individual to another.

Asthma is now the most common chronic illness in children, affecting one in every 15. In North America, 5% of adults are also afflicted. In all, there are about 1 million Canadians and 15 million Americans who suffer from this disease.

The number of new cases and the yearly rate of hospitalization for asthma have increased about 30% over the past 20 years. Even with advances in treatment, asthma deaths among young people have more that doubled.

Asthma cannot be cured with allopathic treatment but it will cure successfully with proper homeopathic treatment.

CAUSES

It is not clear exactly what makes the airways of people with asthma inflamed in the first place. Your inflamed airways may be due to a combination of things. We know that if other people in your family have asthma, you are more likely to develop it. New research suggests that being exposed to things like tobacco smoke, infections, and some allergens early in your life may increase your chances of developing asthma.

There are things in the environment that bring on your asthma symptoms and lead to asthma attacks. Some of the more common things include exercise, allergens, irritants, and viral infections. Some people have asthma only when they exercise or have a viral infection.

The list below gives some examples of things that can bring on asthma symptoms.

Allergens

• Animal dander (from the skin, hair, or feathers of animals)
• Dust mites (contained in house dust)
• Cockroaches
• Mold (indoor and outdoor)
• “Seasonal” pollens
• Year-round dust mites, molds, pets, and insect parts
• Foods, such as fish, egg, peanuts, nuts, cow’s milk, and soy
• Additives, such as sulfites
• Work-related agents, such as latex

About 80% of children and 50% of adults with asthma also have allergies.

Irritants

• Respiratory infections, such as those caused by viral “colds,” bronchitis, and sinusitis
• Drugs, such as aspirin, other NSAIDs (nonsteroidal antiinflammatory drugs), and beta blockers (used to treat blood pressure and other heart conditions)
• Tobacco smoke
• Outdoor factors, such as smog, weather changes, and diesel fumes
• Indoor factors, such as paint, detergents, deodorants, chemicals, and perfumes
• Nighttime
• GERD (gastroesophageal reflux disorder)
• Exercise, especially under cold dry conditions
• Work-related factors, such as chemicals, dusts, gases, and metals
• Emotional factors, such as laughing, crying, yelling, and distress
• Hormonal factors, such as in premenstrual syndrome

SYMPTOMS

The symptoms of asthma vary from person to person and in any individual from time to time. It is important to remember that many of these symptoms can be subtle and similar to those seen in other conditions. All of the symptoms mentioned below can be present in other respiratory, and sometimes, in heart conditions. This potential confusion makes identifying the settings in which the symptoms occur and diagnostic testing very important in recognizing this disorder.

The Four Major Recognized Symptoms:

• Shortness of breath – especially with exertion or at night
• Wheezing – a whistling or hissing sound when breathing out
• Coughing – may be chronic; usually worse at night and early morning; and may occur after exercise or when exposed to cold, dry air
• Chest tightness – may occur with or without the above symptoms

Not all people have these symptoms, and symptoms may vary from one asthma attack to another. Symptoms can differ in how severe they are: Sometimes symptoms can be mildly annoying, other times they can be serious enough to make you stop what you are doing, and sometimes symptoms can be so serious that they are life threatening.Symptoms also differ in how often they occur. Some people with asthma have symptoms only once every few months, others have symptoms every week, and still other people have symptoms every day. With proper treatment, however, most people with asthma can expect to have few or no symptoms.

Who is at risk for Asthma?

In the United States, about 20 million people have been diagnosed with asthma; nearly 9 million of them are children.

Asthma is closely linked to allergies. Most, but not all, people with asthma have allergies. Children with a family history of allergy and asthma are more likely to have asthma.

Although asthma affects people of all ages, it most often starts in childhood. More boys have asthma than girls, but in adulthood, more women have asthma than men.

Although asthma affects people of all races, African Americans are more likely than Caucasians to be hospitalized for asthma attacks and to die from asthma.
