When asthma symptoms appear and are diagnosed in adults older than 20, it is
typically known as adult-onset asthma. Adult-onset asthma is more common
in women than in men and is possibly related to allergies or allergic asthma.
About half of adults who have asthma also have allergies. At other times,
adult-onset asthma may be the result of commonplace substances in work (called
occupational asthma) or home environments, and the asthma symptoms come on
suddenly.
What is asthma?
Asthma is a disorder of the lungs that causes the airways to:
Swell (or become inflamed), specifically in the airway linings
Produce large amounts of mucus that is thicker than normal
Become more narrow because of muscle contractions surrounding the
airways
People who are exposed to environmental irritants, such as tobacco smoke,
mold, dust, feather beds, or perfume. Irritants that bring on asthma symptoms
are called "asthma triggers." Asthma brought on by workplace triggers is called
"occupational asthma."
Chronic cough is a cough that does not go away and is generally a symptom of another disorder such as asthma, allergic rhinitis, sinus infection, cigarette smoking, GERD, postnasal drip, bronchitis, pneumonia, medications, and less frequently tumors or other lung disease. Treatment of chronic cough is dependant upon the cause.
Menopause is the time in a woman's life when menstrual periods permanently stop, also called the “change of life." Menopause symptoms include hot flashes, night sweats, irregular vaginal bleeding, vaginal dryness, painful intercourse, urinary incontinence, weight gain, and emotional symptoms such as mood swings. Treatment of menopausal symptoms varies, and should be discussed with your physician.
Asthma is a common disorder in which
chronic inflammation of the bronchial tubes (bronchi) makes them swell, narrowing the airways. Signs and symptoms include shortness of breath, chest tightness,
cough and wheezing.
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.
Influenza (flu) is a respiratory illness caused by a virus. Flu symptoms include fever, cough, sore throat, runny nose, headache, fatigue, and muscle aches. The flu may be prevented with an annual influenza vaccination.
Obesity is the state of being well above one's normal weight. A person has traditionally been
considered to be obese if they are more than 20 percent over their ideal weight.
That ideal weight must take into account the person's height, age, sex, and
build.
Smoking is an addiction. More than 430,000 deaths occur each year in the U.S. from smoking related illnesses. Secondhand smoke or "passive smoke" also harm family members, coworkers, and others around smokers. There are a number of techniques available to assist people who want to quit smoking.
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.
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.
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.
The definition of obesity varies depending on what one reads, but in general,
it is a chronic condition defined by an excess amount body fat. A certain amount
of body fat is necessary for storing energy, heat insulation, shock absorption,
and other functions. The normal amount of body fat (expressed as percentage of
body fat) is between 25%-30% in women and 18%-23% in men. Women with over 30% body
fat and men with over 25% body fat are considered obese.
The calculation of body mass index (BMI) has also been used in the definition of obesity. The body mass index (BMI) equals a person's weight in kilograms (kg) divided by their height in meters (m) squared. Since BMI describes body weight relative to height, it is strongly correlated with total body fat content in adults.
"Obesity" is defined as a BMI of 30 and above.
How common is obesity?
Obesity has reached epidemic proportions in the United States. One i...
