What is Asthma? Understanding Causes, Triggers, and Management

What is Asthma?

Asthma is a condition that affects the lungs and airways in our body. It causes problems with breathing and includes symptoms such as coughing and wheezing. It is one of the most common chronic conditions worldwide. In 2019 alone, around 262 million people were affected by asthma, and 455,000 people died from it.

While there is no cure for asthma, it can be managed with medications prescribed by doctors and by understanding triggers that can start an asthma attack. In this article, we explain how asthma occurs and discuss common triggers that can be managed to reduce attacks.

The Mechanism Behind Asthma

In asthma, irritants or triggers can cause inflammation of the airways (bronchial tubes), making them narrow. This results in shortness of breath, wheezing, and chest tightness due to reduced airflow to the lungs.

Some contributing factors for asthma include:

• Family history of asthma
• History of allergic conditions
• Exposure to irritants like air pollution, which increases risk
