Asthma is a chronic inflammatory disease of the airways that affects millions of people worldwide. It manifests as episodes of wheezing, shortness of breath, chest tightness, and coughing. Proper asthma management is essential to maintaining a good quality of life and preventing complications. In this blog, we will explore asthma in detail, including its symptoms and the best strategies for managing it effectively.

Understanding asthma

Asthma is a complex condition that involves inflammation and narrowing of the airways, leading to difficulty in breathing. Various factors, including allergens, environmental pollutants, exercise, and respiratory infections, can trigger it. The severity of asthma varies among individuals, with some experiencing mild, occasional symptoms while others suffer from persistent and life-threatening attacks.

The exact cause of asthma remains unclear, but a combination of genetic and environmental factors is believed to contribute to its development. Risk factors include:

• Genetic predisposition: A family history of asthma or allergic conditions increases the likelihood of developing the disease.
• Exposure to allergens: Common allergens such as pollen, dust mites, pet dander, mould, and air pollution can trigger asthma symptoms.
• Respiratory infections: Viral infections, particularly in early childhood, may contribute to airway inflammation and asthma development.
• Environmental irritants: Cold air, strong odours, smoke, and chemical fumes can exacerbate asthma symptoms.
• Stress and emotional factors: Psychological stress and anxiety can influence airway reactivity, worsening asthma symptoms.
• Occupational exposure: Adults exposed to workplace irritants like dust, fumes, or industrial chemicals may develop asthma later in life.

Symptoms and diagnosis

Asthma symptoms can range from mild to severe and often vary from person to person. Common symptoms include:

• A high-pitched whistling sound during breathing.
• Difficulty in breathing, especially during physical exertion or at night.
• A sensation of pressure or constriction in the chest.
• Persistent cough, often worsening at night or early in the morning.
• In severe cases, it causes respiratory distress, such as difficulty speaking, bluish lips, and extreme fatigue, requiring urgent medical attention.

Diagnosing asthma involves a comprehensive assessment, including a review of medical history, physical examination, and lung function tests. Pulmonary function tests, such as spirometry and peak flow measurements, help to determine the extent of airway obstruction. Allergy testing may also be performed to identify specific triggers that exacerbate symptoms.

Effects of asthma on sleep

Asthma and sleep disturbances are closely linked, with many patients experiencing worsening symptoms at night. Nocturnal asthma, characterised by nighttime coughing, wheezing, and shortness of breath, can significantly disrupt sleep quality. 

Nocturnal asthma and sleep

Nocturnal asthma occurs due to various physiological and environmental factors. At night, the body’s natural circadian rhythms influence airway function, potentially leading to increased inflammation and bronchoconstriction. Additionally, exposure to allergens in bedding, such as dust mites, can worsen symptoms. Acid reflux, which is more common at night, may also contribute to nocturnal asthma by irritating the airways.

Poor sleep quality due to nocturnal asthma can result in daytime fatigue, reduced cognitive function, and impaired overall well-being. Addressing these sleep disturbances is essential for optimising asthma control and improving quality of life.

Sleep apnoea in asthma

Obstructive sleep apnoea (OSA) is a sleep disorder characterised by repeated episodes of airway collapse during sleep, leading to intermittent oxygen deprivation. Studies have shown a strong association between asthma and OSA, with many asthma patients experiencing worsened symptoms due to untreated sleep apnoea. 

It is recommended that asthma patients, especially those with persistent nocturnal symptoms, undergo sleep apnoea screening. Treating OSA with continuous positive airway pressure (CPAP) therapy can significantly improve asthma control and reduce the risk of exacerbations.

Effective ways to manage asthma

Managing asthma requires a combination of preventive measures, lifestyle adjustments, and proper treatment to keep symptoms under control and maintain healthy lung function.

Lifestyle adjustments: Adopting healthy habits can significantly improve asthma control. Regular physical activity, when done with precautions, helps to strengthen the lungs. Those with exercise-induced asthma should take preventive measures such as warming up before exercise and using prescribed inhalers if needed. 

Avoiding triggers: Identifying and avoiding asthma triggers is crucial for effective symptom management. Maintain a clean indoor environment by reducing exposure to allergens. Using high-efficiency particulate air (HEPA) filters, washing bedding regularly, and minimising pet dander can prevent asthma flare-ups. Additionally, avoiding tobacco smoke, air pollution, and strong odours is essential for reducing airway irritation.

Healthy diet: A well-balanced diet can support respiratory health. Consuming anti-inflammatory foods like fruits, vegetables, and omega-3 fatty acids may help to improve lung function. Reducing processed foods, artificial additives, and excessive salt intake can lower airway inflammation and enhance asthma control.

Treatment options: If lifestyle changes alone are not enough to control asthma, additional treatments may be necessary. Doctors may prescribe long-term medications to reduce airway inflammation and prevent symptoms. Quick-relief inhalers, like bronchodilators, provide immediate support by relaxing the airway muscles during flare-ups.

Emerging digital tools, such as smart inhalers and mobile apps, can help to track symptoms, monitor medication use, and identify potential triggers. Since treatment varies for each individual, consulting a healthcare professional is essential to determine the most suitable approach.

How to manage asthma attacks?

Despite proper treatment, asthma attacks can still occur, making it crucial to recognise the early warning signs and respond promptly. Symptoms such as severe breathlessness, persistent coughing, wheezing, and chest tightness can worsen, leading to difficulty speaking, bluish lips, and extreme fatigue. If these symptoms develop, seeking emergency medical care immediately is essential to prevent serious complications. If you have an asthma attack, follow these steps to manage your breathing:

• Use your reliever inhaler (fast-acting inhaler) as prescribed.
• Sit upright and stay calm to help keep your airways open.
• Avoid triggers such as smoke, dust, or allergens.
• Seek medical help immediately if your symptoms do not improve after using your inhaler.
