Asthma Signs, Symptoms, and What You Need to Know

Asthma is one of the world's most prevalent chronic respiratory diseases, with a worldwide prevalence that cuts across national, racial, and age boundaries. Inflammation of the airway, or swelling of the airway, narrows the passageway and makes breathing hard and sometimes life-threatening. There are no cures, but asthma can be controlled with proper diagnosis, knowledge of asthma signs, and treatment.

What is Asthma?

Asthma is a chronic illness that results in airway inflammation and constricting. It is difficult to move air in and out of the lungs, and this results in coughing, wheezing, and breathlessness.

When an asthma attack (or flare) happens, the muscles that go around the airways constrict (bronchoconstriction), the airway lining gets inflamed, and the amount of mucus increases, further narrowing the airflow. These types of attacks may be from mild to severe and possibly life-threatening. Who Gets Asthma?

Asthma may happen to anyone, but some individuals are more likely to develop it based on the presence of both genetic and environmental factors. It's particularly prevalent among:

• Children and teens

• Individuals with allergies or eczema

• Individuals with a history of asthma in the family

• Individuals residing in environments with poor air quality

• Individuals with jobs that involve exposure to chemicals, dust, or fumes

• Asthma tends to commence in childhood but can also initiate in adulthood, referred to as adult-onset asthma.

Types of Asthma

Various types of asthma exist, each with specific triggers and presentations:

• Allergic (Extrinsic) Asthma: Induced by allergens like pollen, pet dander, mold, or dust mites.

• Non-Allergic (Intrinsic) Asthma: Initiated by conditions like stress, cold air, exercise, or infections.

• Exercise-Induced Bronchoconstriction (EIB): Asthma attacks come about or become worse with physical exertion.

• Occupational Asthma: Caused by irritants in the workplace, such as fumes, chemicals, or dust.

• Nocturnal Asthma: Symptoms intensify during nighttime, interrupting sleep.

• Cough-Variant Asthma: Characterized primarily by long-term coughing without typical wheezing or shortness of breath.

Signs and Symptoms of Asthma

Asthma symptoms differ from person to person. Some experience mild and occasional symptoms, while others experience frequent and intense attacks.

Common Signs and Symptoms of Asthma are:

• Shortness of Breath: Particularly with physical exertion or nocturnal episodes.

• Wheezing: A whistling sound during breathing, usually during exhalation.

• Chronic Cough: Worse at night or early morning.

• Chest Tightness or Pain: Sensation of something squeezing or lying on your chest.

• Difficulty Sleeping: Due to coughing, wheezing, or shortness of breath.

• Fatigue: Resulting from poor sleeping or not getting enough oxygen.

• Frequent Respiratory Infections: Infections can exacerbate asthma symptoms.
  

In children, asthma can also manifest as constant coughing while playing or recurrent attacks of bronchitis.

What Happens During an Asthma Attack?

An asthma attack is a sudden increase in symptoms caused by triggered inflammation and constriction of the airways. Symptoms of a severe asthma attack include:

• Rapid, shallow breathing

• Severe wheezing or coughing

• Trouble speaking in sentences

• Blue lips or fingernails (indicating low oxygen)

• Use of accessory muscles to breathe (such as neck or chest muscles)

• Confusion or drowsiness
