ABG stands for arterial blood gas test. This test measures oxygen and carbon dioxide levels in the blood and helps assess how well the lungs are functioning. In cases of severe asthma exacerbation, an ABG may be done to evaluate the severity of respiratory distress and guide treatment decisions.

Asthma primarily affects the lungs, but severe or poorly controlled asthma can lead to decreased oxygen levels in the blood. This reduced oxygen supply can potentially affect the brain and other organs too. It may lead to symptoms such as confusion, dizziness, or even loss of consciousness in extreme cases.

Blood work is not typically used to diagnose asthma. However, blood tests may be ordered to exclude other conditions that may cause similar symptoms. Lung function tests like spirometry are more commonly used to assess lung function and diagnose asthma.

Asthma itself does not directly raise blood sugar levels. However, certain medications used to treat asthma, such as corticosteroids, can increase blood sugar levels. Individuals with both asthma and diabetes need to work closely with their doctors to manage their conditions effectively.

There is a genetic component to asthma, i.e. having a family history of asthma or allergies can increase the risk of developing the condition. However, it is essential to note that only some people with a family history of the condition will have it.

Certain environmental conditions can increase the risk of developing asthma or exacerbate existing symptoms. Exposure to allergens, irritants (such as smoke or air pollution), respiratory infections, and poor indoor air quality are the usual suspects.

Asthma primarily affects the lungs. When a person with asthma is exposed to triggers, the airways become inflamed and constricted, making breathing difficult. If not properly managed, over time it can lead to long-term lung damage.

The exact cause of asthma is unknown. However, it is believed to be caused by genetic and environmental factors. Common triggers include allergens (like pollen or dust mites), irritants (such as smoke or air pollution), respiratory infections, exercise, and stress.

No, asthma itself is not contagious. It is a chronic condition that involves inflammation in the lungs that narrows the airways. However, respiratory infections that trigger asthma symptoms, such as the common cold or flu, can be contagious.

Asthma is diagnosed through medical history, physical examination, lung function tests such as spirometry, and sometimes allergy testing. See a doctor if you suspect you have asthma or are encountering symptoms such as wheezing, coughing, or shortness of breath.

You should see a doctor if you are experiencing symptoms such as recurrent coughing, wheezing, shortness of breath, or chest tightness. You must seek prompt medical attention for an accurate diagnosis and appropriate treatment.

A pulmonologist or a respiratory medicine specialist is typically the specialist who treats asthma. They have expertise in diagnosing and managing respiratory conditions, including asthma.

While asthma cannot be prevented entirely, we can reduce the risk of developing asthma. These include avoiding exposure to allergens and irritants. It also includes maintaining good indoor air quality and practising good hygiene to prevent respiratory infections.

The main treatments for asthma include medications and lifestyle changes. Medications can be in the form of inhalers, which help to open up the airways and reduce inflammation. Lifestyle changes may include avoiding triggers, maintaining a healthy weight, and exercising regularly.
