Asthma Symptoms, Diagnosis, and Treatment

What is Asthma?

Asthma is a chronic respiratory condition where the airways in the lungs become narrowed and inflamed, often producing extra mucus. This can lead to breathing difficulties, coughing, wheezing when exhaling, and shortness of breath. Asthma’s impact can range from a minor annoyance to a severe disruption of daily life, and in some cases, it can lead to life-threatening attacks.

Types of Asthma Based on Severity:

  1. Mild Intermittent Asthma: Symptoms less than twice a week; nighttime symptoms less than two times a month. Lung function tests show 80% or more of predicted values. No long-term medications required.

  2. Mild Persistent Asthma: Symptoms three to six times a week; nighttime symptoms three to four times a month. Lung function tests show 80% or more of predicted values.

  3. Moderate Persistent Asthma: Daily symptoms; nighttime symptoms five or more times a month. Lung function tests show 60%-80% of normal values.

  4. Severe Persistent Asthma: Continuous symptoms with frequent nighttime asthma; significant activity limitation. Lung function tests show less than 60% of predicted values.

Asthma Symptoms:

Asthma symptoms can vary widely among individuals. Common signs include:

  • Shortness of breath.
  • Chest tightness or pain.
  • Wheezing when exhaling, particularly in children.
  • Difficulty sleeping due to breathing problems.
  • Coughing or wheezing attacks worsened by respiratory viruses.

Diagnosing Asthma:

Diagnosis involves:

  • Taking a medical history and observing breathing.
  • Performing lung function tests, such as spirometry, to measure air exhalation.
  • Possibly conducting a methacholine challenge test if initial tests are inconclusive. A positive test indicates asthma if lung function drops by at least 20%.

Asthma Treatment:

Asthma management includes using prescribed medications, avoiding triggers, and monitoring symptoms. The main types of asthma medications are:

  1. Anti-inflammatories: Essential for most people with asthma, these medications, like inhaled steroids, reduce airway swelling and mucus. They require consistent daily use and may take weeks to control asthma.

  2. Bronchodilators: These relax the muscles around the airways, improving airflow. They come in short-acting and long-acting forms and can also be used for exercise-induced asthma symptoms.

Proper medication adherence, along with lifestyle adjustments and regular medical consultations, is key to controlling asthma and maintaining quality of life.
