Definition of Asthma

What is asthma?

Asthma is a chronic respiratory condition that affects the airways in your lungs. It is characterized by inflammation and narrowing of the air passages, which results in symptoms such as wheezing, coughing, shortness of breath, and chest tightness. These symptoms can vary in severity and frequency from person to person. While asthma cannot be cured, it can be effectively managed through proper treatment and lifestyle adjustments.

How does asthma affect the body?

When you have asthma, your airways become hyperresponsive to various triggers, leading to inflammation and constriction. This makes it more difficult for air to pass through the airways, causing the characteristic symptoms of asthma. In addition, excessive mucus production further contributes to narrowing the air passages. Understanding how asthma affects the body helps in recognizing the signs and managing the condition effectively.

Causes of Asthma

Genetic factors

Genetic factors play a significant role in the development of asthma. If someone in your immediate family has asthma, you are at a higher risk of developing the condition. Certain genes related to immune responses and the structure of the airways have been linked to asthma.

Environmental factors

Environmental factors, such as exposure to allergens or pollutants, can trigger or worsen asthma symptoms. These may include dust mites, pet dander, pollen, mold, and air pollution. Minimizing exposure to these triggers can help reduce the risk of asthma attacks.


Allergies can contribute to the development or exacerbation of asthma. The immune system reacts to allergens, such as pollen or pet allergens, triggering asthma symptoms in individuals who are sensitized to these substances.

Respiratory infections

Respiratory infections, especially during childhood, can increase the risk of developing asthma. Viral infections, such as the common cold or respiratory syncytial virus (RSV), can cause inflammation in the airways, making them more prone to asthma symptoms.

Risk Factors for Asthma

Family history of asthma

Having a family history of asthma significantly increases the likelihood of developing the condition. If one or both parents have asthma, you have a higher risk of being diagnosed with asthma yourself.

Exposure to secondhand smoke

Exposure to secondhand smoke, especially during childhood, is a significant risk factor for asthma. The harmful chemicals in tobacco smoke irritate the airways, leading to inflammation and increased susceptibility to developing asthma.


Obesity is linked to an increased risk of asthma, particularly in adults. The exact mechanisms behind this association are not fully understood, but it is believed that excess weight contributes to inflammation and changes in lung function.

Occupational exposure to certain substances

Certain occupations involve exposure to substances like chemicals, dust, or fumes that can trigger asthma symptoms or even cause occupational asthma. People working in industries like agriculture, manufacturing, or healthcare may be at a higher risk of developing asthma due to exposure to these substances.

Common Asthma Triggers


Allergens, such as pollen, dust mites, pet dander, and mold, can trigger asthma symptoms in individuals who are allergic to these substances. It is important to identify and minimize exposure to these allergens to reduce the frequency and severity of asthma attacks.


Physical activity and exercise-induced asthma are closely related. Vigorous exercise can cause the airways to narrow, leading to asthma symptoms. This condition is often called exercise-induced bronchoconstriction or exercise-induced asthma. Proper warm-up, using appropriate medications, and avoiding triggers can help minimize exercise-induced symptoms.

Respiratory infections

Respiratory infections, such as the common cold or flu, can trigger asthma symptoms or make existing symptoms worse. Infections cause inflammation in the airways, making them more susceptible to asthma triggers. Good hygiene practices, including regular handwashing, can help reduce the risk of respiratory infections.

Air pollutants

Exposure to air pollutants, both outdoor and indoor, can worsen asthma symptoms. These pollutants include particulate matter, ozone, nitrogen dioxide, and volatile organic compounds. Minimizing exposure to these pollutants through proper ventilation and air filtration systems can help individuals with asthma breathe easier.

Diagnosis of Asthma

Medical history and physical examination

Diagnosing asthma typically involves a thorough evaluation of your medical history and a detailed physical examination. Your healthcare provider will inquire about your symptoms, triggers, and family history, while also listening to your lungs and checking for any signs of inflammation or blockage.

Lung function tests

Lung function tests, such as spirometry, are crucial in diagnosing asthma. These tests measure the amount of air you can exhale forcibly and the rate at which you can exhale. A reduction in these lung function measurements can indicate narrowing of the airways, a characteristic feature of asthma.

Allergy testing

Allergy testing may be recommended to identify specific allergens that may be triggering or exacerbating your asthma symptoms. These tests can include skin prick tests or blood tests to measure allergen-specific antibodies.

Imaging tests

In some cases, imaging tests like chest X-rays or computed tomography (CT) scans may be ordered to rule out other possible causes of respiratory symptoms and to assess the overall health of your lungs.

Early Signs of Asthma

Frequent coughing

One of the early signs of asthma is a persistent cough, especially at night or in response to certain triggers. This cough may be dry and non-productive or accompanied by phlegm.

Wheezing or whistling sound

Wheezing, a high-pitched whistling sound during breathing, is a common symptom of asthma. It is caused by the narrowed airways and occurs when air is forced through constricted passages.

Shortness of breath

Feeling breathless, especially after physical exertion or exposure to triggers, is another early sign of asthma. This occurs due to the difficulty in moving air in and out of the narrowed airways.

Chest tightness

Many people with asthma described a sensation of tightness or pressure in the chest. This may feel like someone is squeezing your chest or like you’re wearing a tight belt.

Fatigue or decreased energy levels

In some individuals, the early signs of asthma may also include unexplained fatigue or decreased energy levels. This can result from the body’s increased effort to breathe and reduced oxygen intake.

Recognizing Asthma Symptoms in Children

Persistent cough

In children, a persistent cough that lasts longer than a week, in the absence of any other obvious cause, may indicate asthma. This cough may worsen at night or during physical activity.

Rapid breathing

If you notice your child’s breathing is faster than usual, especially during normal activities, it could be a sign of asthma. Rapid breathing helps compensate for the narrowed airways.

Retraction of chest wall during breathing

Children with asthma may exhibit visible retraction or inward pulling of the chest wall during breathing. This can be seen as the skin between the ribs or above the collarbones being drawn inward.

Difficulty feeding in infants

Infants with asthma may experience difficulty feeding, as it requires coordination between breathing and sucking. If your infant consistently struggles to feed or shows signs of discomfort during feeding, it may be worth discussing with a healthcare professional.

Tiredness or irritability

Children with undiagnosed or poorly controlled asthma may exhibit signs of tiredness or irritability due to their body’s struggles with breathing. These symptoms can impact their overall quality of life and should be addressed.

Emergency Signs of Asthma

Severe wheezing or coughing

Severe, persistent wheezing or coughing that does not ease with usual medications or treatments can be an emergency sign of asthma. This may indicate a severe asthma attack requiring immediate medical attention.

Very rapid breathing

If you or someone you know is experiencing very rapid breathing, where the breaths are shallow and frequent, it could be a sign of a severe asthma exacerbation. Seek medical help promptly if this occurs.

Inability to speak or complete sentences

A person with asthma experiencing extreme difficulty speaking or completing sentences due to breathlessness should be considered a medical emergency. It indicates that the person is not getting enough air and needs immediate attention.

Extreme chest pain

Chest pain that is intense or feels like a crushing sensation can occur during a severe asthma attack. This may be a sign of reduced oxygen supply and should not be ignored.

Blue lips or face

If you notice a bluish discoloration of the lips or face, it is a sign of decreased oxygen levels in the blood. This requires immediate medical attention, as it indicates a severe lack of oxygen due to the narrowed airways.

Prevention of Asthma

Avoiding asthma triggers

Identifying and avoiding triggers is an essential part of managing asthma. By minimizing exposure to allergens, irritants, and pollutants, you can reduce the frequency and severity of asthma symptoms.

Maintaining a clean indoor environment

Keeping a clean indoor environment can help reduce exposure to dust mites, pet dander, and mold, all of which are known triggers of asthma. Regular cleaning, proper ventilation, and using allergen-proof bedding can be helpful.

Getting vaccinated

Vaccinations, especially the influenza (flu) vaccine and the pneumococcal vaccine, are recommended for individuals with asthma to minimize the risk of respiratory infections, which can trigger asthma symptoms.

Regular exercise and healthy diet

Engaging in regular exercise and maintaining a healthy diet can improve overall lung function and strengthen the respiratory system. Physical fitness can minimize the likelihood and severity of asthma symptoms.
