Asthma Inhalers

What is Asthma? 

Asthma is a chronic disorder that makes the airways of your lungs swell and narrow. It can cause breathing difficulty, trigger coughing, a whistling sound when you breathe out, and shortness of breath. 

For some people, asthma is just a minor problem, but for others, it is a significant disorder that interferes with regular activities and sometimes leads to life-threatening asthma attacks. 

Though asthma cannot be cured, its symptoms can be controlled. Since asthma changes with time, you must consult a doctor and track signs & symptoms so that treatment can be adjusted when required. 

Symptoms of asthma 

When it comes to asthma signs and symptoms, they differ from person to person. You can suffer from infrequent asthma attacks, have symptoms only at certain times, like when exercising, or experience symptoms all the time. 

Asthma symptoms & signs include:

  • Chest tightness or pain
  • Shortness of breath
  • Wheezing when exhaling is a common symptom of asthma in children
  • Coughing or wheezing attacks which get worse by respiratory viruses like cold or flu
  • Difficulty in sleeping due to shortness of breath, wheezing or coughing

Symptoms that your asthma is possibly worsening include:

  • Asthma signs and symptoms that are more frequent and bothersome 
  • Increasing difficulty breathing
  • Need to use a quick-relief inhaler more often

For some people, asthma symptoms flare up in some conditions:

  • Exercise-induced asthma can get worse when the air is cold and dry.
  • Occupational asthma triggered by workplace irritants like chemical gases, fumes, or dust
  • Allergy-induced asthma is activated by airborne substances like mold spores, cockroach waste, pollen, or particles of skin & dried saliva shed by pets. 

Causes of asthma 

Here are some factors that are responsible for causing asthma:

  • Allergies 

Having allergies can increase your risk of suffering from asthma

  • Environmental factors 

People might develop asthma after exposure to things that irritate airways. These substances include fumes, allergens, toxins & second or third-hand smoke. 

These are usually harmful to infants and young children whose immune systems have not developed properly. 

  • Genetics 

In case your family has a history of asthma or allergic diseases, then you can have a high risk of developing this medical ailment. 

  • Respiratory infections

Certain respiratory infections like respiratory syncytial virus (RSV) might damage the developing lungs of young children. 

What is an asthma attack? 

When you breathe normally, muscles around the airways relax and allow air to move quickly. During an asthma attack, the following things might happen:

  • Bronchospasm

Muscles around the airways constrict. Once they are tightened, they make your airways narrow. This further restricts air from flowing correctly through constricted airways. 

  • Production of mucus

During an asthma attack, your body starts creating more mucus. The thick mucus blocks airways. 

  • Inflammation 

The lining of the airways becomes swollen and doesn't let air pass in or out of the lungs. 

When airways get tighter, you automatically start making a sound known as wheezing while breathing. This noise is caused by your airways when you breathe out. 

Also, you can hear an asthma attack known as exacerbation or flare-up. It's the term for when your asthma is not controlled.

Types of asthma 

Asthma is divided into types based on the cause and severity of symptoms. Doctors identify asthma as:

  • Intermittent

This type of asthma comes and goes, which can make you feel normal in between asthma flares. 

  • Persistent 

Persistent asthma means you experience symptoms most of the time. Symptoms can be mild, moderate or severe. Doctors consider asthma severity on how often you suffer from symptoms. They also think about how well you can perform during an asthma attack.  

How asthma is diagnosed? 

The doctor will first review your medical history, including information about your parents. The doctor will also ask about your symptoms. Your healthcare provider will know about a history of allergies, eczema, and other lung disorders. 

Your doctor might use spirometry to measure airflow through the lungs. It is also helpful in diagnosing and monitoring your progress with asthma treatment. A chest X-ray, blood test, or skin test might be conducted.

Types of asthma medications 

Asthma medications can be categorised Based on the action's nature and the effects produced. 

Here are the different types of asthma medications:

  • Long-term asthma medicines

Several patients might need asthma medicine to prevent asthma and its symptoms effectively. This type of treatment can take a few months to show its complete effects. 

Some long-term medicines include:

  • Inhaled corticosteroids

These anti-inflammatory medicines reduce symptoms of swelling and constriction in muscle and blood vessels along your airways. 

Corticosteroids have high effectiveness and help manage asthma in the long term. 

  • Leukotriene modifiers

When triggered, the immune system starts releasing chemicals called leukotrienes, which activate inflammatory symptoms of asthma. 

Leukotriene modifiers assist to modify this behavior and prevent symptoms for 24 hours. 

Some Leukotriene modifiers include Zileuton, Montelukast, and others. 

  • Short or quick-use asthma medications 

Short-use asthma medications show quick action and work on the lungs by relaxing and loosening your airway. 

When taken, they begin working within minutes and last for a few hours. Such medicines are safe for daily use. 

  • Short-acting beta-agonists

These rescue inhalers provide quick relief from asthma symptoms and are used twice a week only. 

Some commonly used short-acting beta-agonists are Albuterol and Levalbuterol. 

  • Systemic corticosteroids 

These medicines reduce swelling and inflammation in the airways. It would help if you took them with a rescue inhaler to treat asthma attacks. 

Systemic corticosteroids can be taken orally or given intravenously to experience quick action. 

Some common systemic corticosteroids include Prednisolone, Methylprednisolone, and others.

  • Anticholinergics 

Anticholinergics are bronchodilators that air with expanding airway muscles. They are used alone or with short-acting beta-agonists. 

Doctors recommend some frequently used anticholinergics such as Tiotropium bromide and Ipratropium.
