Asthma is a common chronic respiratory disease that, if not properly controlled, can lead to severe, even life-threatening, attacks. Many asthma patients, due to resistance to steroids or misdiagnosis of their condition, over-rely on bronchodilators, delaying treatment and exacerbating their condition. Respiratory specialist Dr. Kwong Kwok-chu reminds us that asthma treatment cannot rely solely on bronchodilators. Inhaled steroids, when necessary, and regular checkups are necessary to effectively control the condition.
Asthma severity and mortality risk
More than 33 people in Hong Kong suffer fromasthmaEach year, approximately 70-90 people die from asthma, of whom approximately 30 are elderly. Delaying medical treatment, over-reliance on bronchodilators, interrupting treatment, or failing to recognize worsening conditions can lead to worsening asthma symptoms and even death.
Asthma Treatment: The Difference Between Controller and Reliever Medications
Dr. Kuang pointed out that the goal of asthma treatment is to completely control the disease and stabilizePulmonary function, rather than just relieving symptoms. Doctors need to continually assess patients' responses to medications to prevent future attacks. External factors such as inhaled allergens, air pollution, and weather changes, as well as indoor allergens like dust mites and pet dander, can trigger asthma, causing symptoms such as wheezing, chest tightness, and coughing.
Asthma treatment drugs are divided into "controller drugs" and "reliever drugs". Inhaled steroids are "controller drugs" and have anti-inflammatory effects, which can reduce acute attacks, control the disease, and stabilize lung function. "Reliever drugs" have a bronchodilator effect, but cannot controlInflammation of the tracheaOver-reliance on reliever medications can worsen symptoms and even cause tracheal remodeling, leading to permanent tracheal damage and obstruction. Dr. Kuang emphasized that controller medications should be used when necessary to effectively control asthma.
Case Study: The Consequences of Steroid Resistance
Dr. Kuang shared the case of an asthma patient in his 40s. He had suffered from asthma since childhood. He resisted the use of inhaled steroids, relying solely on reliever medications to alleviate symptoms during flare-ups. This ultimately led to airway remodeling and permanent lung function impairment. Currently, he requires ongoing medication to control exacerbations. In reality, only approximately 10% of asthma patients achieve effective control of their condition.
Asthma treatment requires proactive action, not relying solely on symptoms. Regular medical checkups and following your doctor's instructions for medication are essential for effective asthma control, preventing worsening of the condition, and maintaining healthy breathing. Never stop taking medication on your own or become overly reliant on bronchodilators, which can delay treatment.
