Here’s what you need to know about asthma

Did you know approximately five to 10 per cent of patients with asthma can develop severe uncontrolled asthma, which requires individually tailored treatment?

Imran Satia, assistant professor in the Department of Medicine at McMaster University and a respirologist at the Firestone Institute for Respiratory Health, St. Joseph’s Hospital and Hamilton Health Sciences, explains that asthma is a chronic condition that affects the airways in the lungs. Symptoms may include shortness of breath, wheezing, chest tightness and coughing.

“Sometimes, symptoms can become so severe that they result in an asthma attack,” says Satia.

Respiratory viruses, allergens – like pollen, dust mites and mold, irritants – such as smoke, air pollution and cold air, and physical activity that leads to exercise-induced narrowing of the airways are all common asthma triggers.

“Identifying and managing personal triggers is a key part of asthma treatment,” explains Satia. “While there is no cure for asthma, it can be managed effectively with proper treatment strategies.”

The progression and management of asthma can differ notably between those who develop it early in life and those who experience late-onset asthma, which appears in adulthood.

“It’s important that patients with asthma remain vigilant about asthma and stay in touch with their healthcare team to manage the condition effectively,” Satia adds.
