Asthma is a chronic inflammation of the bronchial tubes (airways) that causes
swelling and narrowing (constriction) of the airways. The result is difficulty
breathing. The bronchial narrowing is usually either totally or at least
partially reversible with treatments.
Bronchial tubes that are chronically inflamed may become overly sensitive to
allergens (specific triggers) or irritants (nonspecific triggers). The airways
may become "twitchy" and remain in a state of heightened sensitivity. This
is called "bronchial hyperreactivity" (BHR). It is likely that there is a
spectrum of bronchial hyperreactivity in all individuals. However, it is clear
that asthmatics and allergic individuals (without apparent asthma) have a
greater degree of bronchial hyperreactivity than nonasthmatic and nonallergic
people. In sensitive individuals, the bronchial tubes are more likely to swell
and constrict when exposed to triggers such as allergens, tobacco smoke, or
exercise. Amongst asthmatics, some may have mild BHR and no symptoms while
others may have severe BHR and chronic symptoms.
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.
From the past to the present
Physicians in ancient Greece used the word asthma to describe
breathlessness or gasping. They believed that asthma was derived from internal
imbalances, which could be restored by healthy diet, plant and animal remedies,
or lifestyle changes.
Allergy jargon
Asthma is derived from the Greek word panos, meaning panting.
Chinese healers understood that xiao-chiran, or "wheezy breathing," was
a sign of imbalance in the life force they called qi. They restored
qi by means of herbs, acupuncture, massage, diet, and exercise.
The Hindu philosophers connected the soul and breath as part of the mind,
body, and spirit connection. Yoga uses control of breathing to enhance
meditation. Indian physicians taught these breathing techniques to help manage
asthma.
Allergy fact
Maimonides was a renowned 12th-century rabbi and physician who practiced in
the court of the sultan of Egypt. He recommended to one of the royal princes
with asthma that he eat, drink, and sleep less. He also advised that he engage
in less sexual activity, avoid the polluted city environment, and eat a specific
remedy...chicken soup.
The balance of the "four humors," which was derived from the Greco-Roman
times, influenced European medicine until the middle of the 18th century.
In a healthy person, the four humors, or bodily fluids -- blood, black bile,
yellow bile, and phlegm -- were in balance. An excess of one of these humors
determined what kinds of disorders were present. Asthmatics who were noted for
their coughing, congestion, and excess mucus (phlegm) production were therefore
regarded as "phlegmatic."
By the 1800s, aided by the invention of the stethoscope, physicians began
to recognize asthma as a specific disease. However, patients still requested the
traditional treatments of the day, such as bloodletting, herbs, and smoking
tobacco. These methods were used for a variety of conditions, including asthma.
Of the many remedies that were advertised for asthma throughout the 19th
century, none were particularly helpful.
Allergy fact
As early as 1892, the famous Canadian-American physician Sir William Osler
suggested that inflammation played an important role in asthma.
Bronchial dilators first appeared in the 1930s and were improved in the
1950s. Shortly thereafter, corticosteroid drugs that treated inflammation
appeared and have become the mainstay of therapy used today.
Eczema, also known as dermatitis, is a general term for many types of skin inflammation. The most common form of eczema is atopic dermatitis. The other forms of eczema include: contact eczema, seborrheic eczema, Nummular eczema, Neurodermatitis, stasis dermatitis, and dyshidrotic eczema. Symptoms, diagnosis, and treatment of eczema may vary from person to person and may depend on the type of eczema.
GERD (gastroesophageal reflux disease) is a condition in which the acidified liquid
contents of the stomach backs up into the esophagus. The symptoms of uncomplicated GERD are heartburn,
regurgitation, and nausea. Effective treatment is available for most patients with GERD.
Sinus infection (sinusitis) signs and symptoms include headache, fever, and facial tenderness, pressure, or pain. Treatments of sinus infections are generally with antibiotics and at times, home remedies.
Bronchitis is a disease of the respiratory system in which the bronchial passages become inflamed. There are two types of bronchitis, acute and chronic. Symptoms of acute bronchitis include frequent cough with mucus, lack of energy, wheezing, and possible fever. Treatment may require medication such as bronchial inhalers and predinsone. Supportive treatment is focused on relieving the symptoms with fever reducers, cough suppressants, and rest. Treatment may be more aggressive in patients with pre-existing conditions such as empyema, COPD, or cigarette smoking.
COPD (chronic obstructive pulmonary disease) is a disorder that persistently obstructs bronchial airflow. COPD mainly involves three related conditions, chronic bronchitis, chronic asthma, and emphysema. Symptoms of COPD include chronic cough, shortness of breath, frequent respiratory infections, wheezing, morning headaches, and pulmonary hypertension. Treatment of COPD is focused on the related condition(s).
Whooping cough (pertussis) is highly contagious respiratory infection that is caused by the bacteria Bordetella pertussis. There are an estimated 300,000 plus deaths annually from whooping cough (pertussis). Whopping cough commonly affects infants and young children, but can be prevented with immunization with the vaccine. First stage whooping cough symptoms are a runny nose, sneezing, low-grade fever, a mild cough with the cough gradually becoming more severe. After one to two weeks, the second stage of whooping cough begins.
An allergy refers to a misguided reaction by our immune system in response to bodily contact with certain foreign substances. When these allergens come in contact with the body, it causes the immune system to develop an allergic reaction in people who are allergic to it. It is estimated that 50 million North Americans are affected by allergic conditions. The parts of the body that are prone to react to allergies include the eyes, nose, lungs, skin, and stomach. Common allergic disorders include hay fever, asthma, allergic eyes, allergic eczema, hives, and allergic shock.
Eye allergy (or allergic eye disease) are typically associated with hay fever and atopic dermatitis. Medications and cosmetics may cause eye allergies. Allergic eye conditions include allergic conjunctivitis, conjunctivitis with atopic dermatitis, vernal keratoconjunctivitis, and giant papillary conjunctivitis. Dry eye, tear-duct obstruction, and conjunctivitis due to infection are frequently confused with eye allergies. Eye allergies may be treated with topical antihistamines, decongestants, topical mast-cell stabilizers, topical antiinflammatory drugs, systemic medications, and allergy shots.
Chronic bronchitis is a cough that occurs daily with production of sputum that lasts for at least three months, two years in a row. Causes of chronic bronchitis include cigarette smoking, inhaled irritants, and underlying disease processes (such as asthma, or congestive heart failure). Symptoms include cough, shortness of breath, and wheezing. Treatments include bronchodilators and steroids. Complications of chronic bronchitis include COPD and emphysema.
Mold exposure may cause symptoms in people who are sensitive to molds. Symptoms of mold allergy include sneezing, runny nose, wheezing, coughing, redness of the eyes, and rash. Prevent mold growth by keeping indoor humidity low, between 30%-50%, using bathroom fans when showering, repairing plumbing leaks quickly, and using an air conditioner during humid seasons.
Premenstrual syndrome (PMS) is a combination of physical and emotional disturbances that occur after a woman ovulates and ends with menstruation. Common PMS symptoms include depression, irritability, crying, oversensitivity, and mood swings. For some women PMS symptoms can be controlled with medications and lifestyle changes such as exercise, nutrition, and a family and friend support system.
Insomnia is the perception or complaint of inadequate or poor-quality sleep because of difficulty falling asleep; waking up frequently during the night with difficulty returning to sleep; waking up too early in the morning; or unrefreshing sleep. Secondary insomnia is the most common type of insomnia. Treatment for insomnia include lifestyle changes, cognitive behavioral therapy, and medication.
Patients who have infrequent, mild bouts of asthma attacks may use over-the-counter (OTC) medications to treat their asthma symptoms. OTC asthma medicines are limited to epinephrine and ephedrine. These OTC drugs are best used with the guidance of a physician, as there may be side effects and the drugs may not be very effective.
Fatigue can be described in various ways. Sometimes fatigue is described as feeling a lack of energy and motivation (both mental and physical). The causes of fatigue are generally related to a variety of conditions or diseases for example, anemia, mono, medications, sleep problems, cancer, anxiety, heart disease, drug abuse, and more. Treatment of fatigue is generally directed toward the condition or disease that is causing the fatigue.
Asthma, the main cause of chronic illness in children, has signs and symptoms in children that include frequent coughing spells, low energy while playing, complaints of chest "hurting," wheezing while breathing, shortness of breath, and feelings of tiredness. Treatment will involve a doctor creating an asthma action plan which will describe the use of asthma medications and when to seek emergency care for the child.
Hay fever (allergic rhinitis) is an irritation of the nose caused by pollen and is associated with the following allergic symptoms: nasal congestion, runny nose, sneezing, eye and nose itching, and tearing eyes. Avoidance of known allergens is the recommended treatment, but if this is not possible, antihistamines, decongestants, and nasal sprays may help alleviate symptoms.
There are many unusual symptoms of asthma, including sighing, difficulty sleeping, anxiety, chronic cough, recurrent walking pneumonia, and rapid breathing. These symptoms may vary from individual to individual. These asthma complexities make it difficult to accurately diagnose and treat asthma.
Sleepwalking is a condition in which an individual walks or does other activities while asleep. Factors associated with sleepwalking include genetic, environmental, and physiological. Episodes of sleepwalking may include quiet walking to agitated running. Conditions that may have similar symptoms of sleepwalking, but are not include night terrors, confusional arousals, and nocturnal seizures. Treatment of sleepwalking generally include preventative measures. Medication may be prescribed if necessary.
There are two types of asthma medications: long-term control with anti-inflammatory drugs and quick relief from bronchodilators. Asthma medicines may be inhaled using a metered dose inhaler or nebulizer or they may be taken orally. People with high blood pressure, diabetes, thyroid disease, or heart disease shouldn't take OTC drugs like Primatene Mist and Bronkaid.
Acid backing up into the larynx (voice box), it causes reflux laryngitis. Irritation of the lining of the esophagus, larynx, and throat can lead to esophagitis, sinusitis, strictures, hoarseness, throat clearing, swallowing problems, asthma, chronic cough, and more. Typical symptoms of reflux laryngitis include heartburn, hoarseness, or a sensation of a foreign body in the throat. Reflux laryngitis can be treated with OTC medication, prescription medication, and lifestyle changes.
Adult-onset asthma is asthma that is diagnosed in people over 20 years of age. Symptoms include wheezing, coughing, shortness of breath and difficulty breathing. Treatment may involve anti-inflammatory medications or bronchodilators.
Common sources of indoor allergens include dust mites, cockroaches, molds, pets, and plants. Managing allergies caused by indoor allergens means reducing your exposure to them.
The lungs are primarily responsible for the exchange of oxygen and carbon dioxide between the air we breathe and the blood. Eliminating carbon dioxide from the blood is important, because as it builds up in the blood, headaches, drowsiness, coma, and eventually death may occur. The air we breathe in (inhalation) is warmed, humidified, and cleaned by the nose and the lungs.
Occupational asthma is a type of asthma caused by exposure to a substance in the workplace. Symptoms and signs include wheezing, chest tightness, and shortness of breath. The usual treatment for occupational asthma involves removal from exposure and the use of bronchodilators and inhaled anti-inflammatory medicines.
Exercise-induced asthma is asthma triggered by vigorous exercise. Symptoms include coughing, shortness of breath, chest tightness, wheezing, and fatigue while exercising. Preventing exercise-induced asthma attacks involves using inhaled medicines before exercising, performing warm-up exercises and cooling down afterward, avoiding exercising outdoors when pollen counts are high, restricting exercise when you have a viral infection, and wearing a mask over your nose and mouth when exercising in cold weather.
Secondhand smoke can cause illness and disease in nonsmokers. Some of these conditions include lung cancer, heart disease, respiratory illnesses such as asthma, SIDS, bronchitis, and pneumonia. Learn how you can protect yourself and your family from secondhand smoke exposure in the home environment and workplace.
