Asthma is the leading cause of chronic illness in
children. It affects as
many as 10%-12% of children in the U.S. and, for unknown reasons, is steadily
increasing. It can begin at any age, but most children have their first
symptoms by age 5.
One of the more frequent questions my patients ask me concerns the relative risk of their child developing allergies or asthma. In previous Doctors' Views, I have raised issues relating the environment to the development of allergies or asthma. However, both a genetic predisposition and environmental/lifestyle factors are necessary for these conditions to develop.
The incidence of asthma has risen dramatically in the past 20 years—a period too short to reflect any significant changes in the gene pool. This supports the important role that environmental influences (allergy, infection, lifestyle, and diet) have on the development of asthma.
What role then does genetics (heredity) play in asthma? A genetic link in asthma has long been suspected primarily due to "clustering" of cases within families and in identical twins. This does not prove a genetic cause, since it may also reflect shared environmental exposures. Several studies conclude that heredity increases your chances of developing asthma, particularly if allergies or other allergic conditions are present. Moreover, you may pass this tendency to asthma to the next generation. So, what are the chances that your child will develop asthma?
Exposure to tobacco smoke before and/or after birth
Being male
Being black
Being raised in a low-income environment
Why are more children getting asthma?
No one really knows why more and more children are developing asthma. Some
experts suggest that children are being exposed to more and more allergens such
as dust, air pollution, and second-hand smoke. These factors all are triggers
of asthma. Others suspect that children are not exposed to enough childhood
illnesses to build up their immune system. It appears that a disorder of the
immune system where the body fails to make enough protective antibodies may
play a role in causing asthma.
And still others suggest that decreasing rates of breastfeeding have
prevented important substances of the immune system from being passed on to
babies.
How can I tell if my child has asthma?
Signs and symptoms to look for include:
Frequent coughing spells, which may occur during play, at night, or while laughing. It is important to know that cough may be the only symptom present.
Keep in mind that not all children have the same asthma symptoms, and these
symptoms can vary from asthma episode to the next episode in the same child.
Also note that not all wheezing or coughing is caused by asthma.
In kids under 5 years of age, the most common cause of asthma-like symptoms
is upper respiratory viral infections such as the common cold.
If your child has problem breathing, take him or her to the doctor
immediately for an evaluation.
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.
Headaches can be divided into two categories: primary headaches and secondary headaches. Migraine headaches, tension headaches, and cluster headaches are considered primary headaches. Secondary headaches are caused by disease. Headache symptoms vary with the headache type. Over-the-counter pain relievers provide short-term relief for most headaches.
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.
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.
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.
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.
It's important to know whether you will breastfeed or bottle-feed your baby prior to delivery, as the breasts' ability to produce milk diminishes soon after childbirth without the stimulation of breastfeeding. Breast milk is easily digested by babies and contains infection-fighting antibodies and cholesterol, which promotes brain growth. Formula-fed babies actually need to eat somewhat less often since formula is less readily digested by the baby than human milk. This article explores the advantages and disadvantages of both forms of feeding.
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.
Vitamin D deficiency has been linked with rickets, cancer, cardiovascular disease, severe asthma in children and cognitive impairment in older adults. Causes include not ingesting enough of the vitamin over time, having limited exposure to sunlight, having dark skin, and obesity. Symptoms include bone pain and muscle weakness. Treatment for vitamin D deficiency involves obtaining more vitamin D through supplements, diet, or exposure to sunlight.
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.
Biologic rhythms, or biorhythms, are how our bodies respond to the regular phases of the sun, moon, and seasons. A medical chronobiologist studies how the "body clock" or biorhythms affect diseases and how the body clock responds to treatment of diseases and conditions at different times of the day.
Children's health is focused on the well-being of children from conception through adolescence. There are many aspects of children's health, including growth and development, illnesses, injuries, behavior, mental illness, family health and community health.
Kids get headaches and migraines too. Many adults with headaches started having them as kids, in fact, 20% of adult headache sufferers say their headaches started before age 10, and 50% report their headaches started before age 20.
Fast food consumption and lack of exercise are just a couple of causes of childhood obesity. Health effects of childhood obesity include type 2 diabetes, heart attack, stroke, high cholesterol, asthma, sleep apnea, gallstones, fatty liver disease, GERD, depression, and eating disorders.
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.
Doctors and asthma specialists recognize that asthma has two main
components: airway inflammation and acute bronchoconstriction (constriction of
the airways). Research has shown that reducing and preventing further
inflammation is the key to preventing asthma attacks, hospitalizations, and
death from asthma.
Long-term control asthma medications are taken daily over an extended period
of time to achieve and maintain control of persistent asthma (asthma that
causes symptoms more than twice a week and frequent attacks that affect
activity).
The most effective long-term control asthma medications are those that stop
airway inflammation (anti-inflammatory drugs), but there are others that are
often used along with anti-inflammatory drugs to enhance their effect.
Long-term control asthma medications include:
Corticosteroids (The inhaled form is the anti-inflammatory dru...
