Asthma symptoms causes and best treatment options

Understanding Asthma: A Comprehensive Guide

Asthma is a chronic condition that affects the airways, causing inflammation and narrowing, which leads to symptoms like wheezing, shortness of breath, and chest tightness. It’s a condition that affects millions in the UK, and many people have similar concerns about how to manage it. This article addresses five key questions people frequently ask about asthma, offering detailed explanations to help improve understanding and control of the condition.

What Causes Asthma, and Who Is at Risk?

Asthma is caused by a combination of genetic and environmental factors, and while the exact mechanism behind the condition isn’t entirely understood, researchers have pinpointed some common contributors. People with a family history of asthma or allergies are more likely to develop the condition. Additionally, early exposure to allergens like dust mites, pollen, mould, and pet dander can increase the risk of asthma, particularly in childhood.

One major environmental factor is air pollution, especially in urban areas where levels of pollutants like nitrogen dioxide and particulate matter are higher. These pollutants can trigger or worsen asthma symptoms by irritating the airways. For some individuals, asthma may be linked to their work environment—this is known as occupational asthma. People who are regularly exposed to dust, fumes, or chemicals at work can develop asthma even if they had no previous respiratory issues.

Asthma can develop at any age. While it’s commonly diagnosed in childhood, it’s not unusual for adults to develop asthma, particularly if they have ongoing exposure to respiratory irritants. In children, early childhood respiratory infections, such as bronchiolitis, can increase the likelihood of developing asthma. Smoking, both active and passive, also plays a significant role in the onset of asthma, especially in children who are exposed to second-hand smoke. Smoking during pregnancy increases the risk of the child developing asthma later in life.

Living with asthma means becoming aware of the things that can trigger symptoms. These triggers vary from person to person, but common culprits include viral infections, cold air, exercise, strong emotions like stress, and allergens like pollen. Recognising these triggers is the first step toward managing asthma and reducing flare-ups. Preventative measures, such as avoiding known allergens, wearing a mask in polluted areas, and quitting smoking, can help reduce the severity of asthma over time.

How Is Asthma Diagnosed, and What Tests Are Involved?

Diagnosing asthma is not always straightforward, as the symptoms can overlap with other respiratory conditions. The first step in the diagnosis process is usually a detailed assessment of symptoms and a patient’s medical history. Your GP will ask about how often you experience symptoms like wheezing, coughing, and shortness of breath, as well as any possible triggers, such as exercise, allergies, or stress.

To confirm a diagnosis of asthma, your doctor may use several tests to assess lung function. One common test is spirometry, which measures how much air you can breathe out and how quickly you can do so. This test helps to determine whether your airways are obstructed, a key feature of asthma. During the spirometry test, you will be asked to blow into a machine that records the amount of air you can exhale forcefully in one second (FEV1). A low FEV1 reading suggests that your airways are narrowed, which is typical in asthma patients.

Another test used in asthma diagnosis is the peak flow test, which measures how fast you can blow air out of your lungs. This test can be done over several weeks to monitor variations in your airflow, especially at different times of the day. Asthma is often worse in the morning and late at night, so significant variations in peak flow readings can help confirm the diagnosis.

For some individuals, particularly those with allergic asthma, an allergy test may be recommended to identify triggers that worsen asthma symptoms. These tests can be done using skin prick tests or blood tests to check for sensitivities to common allergens like pollen, dust mites, or pet dander. Another diagnostic tool used is a FeNO (Fractional exhaled Nitric Oxide) test, which measures the amount of nitric oxide in your breath. Higher levels of nitric oxide can indicate inflammation in the airways, a hallmark of asthma.

In some cases, particularly in children or individuals with unclear symptoms, a methacholine challenge test may be used. Methacholine is a substance that, when inhaled, causes the airways to narrow in people with asthma. If the test results in narrowing of the airways, it further confirms the presence of asthma.

What Are the Different Types of Asthma, and How Do They Affect People?

Asthma isn’t a one-size-fits-all condition. People experience it in different ways depending on various factors like age, environment, and overall health. One of the most common forms is allergic asthma, where symptoms are triggered by allergens such as pollen, pet dander, or dust mites. This type of asthma is often seasonal and may flare up during specific times of the year when pollen levels are high or when you’re in contact with animals.

Exercise-induced asthma is another common type, particularly in children and athletes. This form is triggered by physical activity, particularly when the air is cold or dry. Symptoms include coughing, wheezing, and shortness of breath during or after exercise. For many people with exercise-induced asthma, the symptoms can be managed effectively with pre-exercise use of a reliever inhaler.

Occupational asthma is a type that develops due to exposure to irritants in the workplace. People who work in industries involving chemicals, dust, or fumes are particularly at risk. Symptoms may worsen during the workweek and improve when away from the workplace. Identifying and avoiding triggers in the workplace, or using protective equipment, can help manage occupational asthma.

Night-time asthma, or nocturnal asthma, is a form that primarily affects people during the night. It’s often exacerbated by lying down, cold air, or allergens in the bedroom, like dust mites. This type of asthma can significantly disrupt sleep, leading to fatigue and reduced quality of life. People with nocturnal asthma may need to adjust their treatment plan to include higher doses of preventer medication or additional therapies to manage night-time symptoms.

Steroid-resistant asthma is a more severe form, where the standard treatment with corticosteroid inhalers doesn’t adequately control symptoms. This type may require more aggressive treatment, including higher doses of oral steroids or biologic treatments, which target specific parts of the immune system responsible for airway inflammation. People with steroid-resistant asthma typically work closely with asthma specialists to find an effective treatment plan.

How Is Asthma Treated and Managed?

While there’s no cure for asthma, it can be effectively managed with the right combination of medications and lifestyle adjustments. The cornerstone of asthma treatment is inhalers, which deliver medication directly to the lungs. There are two main types of inhalers: preventer inhalers, which reduce inflammation in the airways and should be used daily, and reliever inhalers, which provide quick relief during an asthma attack.

Preventer inhalers contain corticosteroids, which help reduce the sensitivity of the airways and lower the chances of an asthma flare-up. These inhalers are usually prescribed to be taken twice daily, regardless of whether symptoms are present. It’s crucial to use them consistently, as they work over time to keep the airways calm.

Reliever inhalers, often referred to as rescue inhalers, are used to treat sudden asthma symptoms. They contain fast-acting bronchodilators, which quickly open the airways and make breathing easier. These inhalers are typically blue and should be carried at all times for emergency use. If you find that you need to use your reliever inhaler more than three times a week, it’s a sign that your asthma isn’t well controlled, and you should see your GP for a review of your treatment plan.

In some cases, when inhalers alone aren’t enough to control symptoms, additional medications may be prescribed. These can include oral steroids for short-term use during severe flare-ups, leukotriene receptor antagonists, or biologic therapies. Biologics are a newer form of treatment that target specific molecules involved in the inflammatory response and are typically reserved for people with severe asthma that doesn’t respond to traditional treatments.

What Should You Do During an Asthma Attack?

Asthma attacks can be frightening, but knowing how to respond can make a big difference. During an asthma attack, the muscles around the airways tighten, and the lining of the airways becomes inflamed, causing difficulty breathing. Symptoms include severe shortness of breath, wheezing, coughing, and tightness in the chest.

The first step in managing an asthma attack is to use your reliever inhaler. Take two puffs of your inhaler immediately, and if your symptoms don’t improve, you can take additional puffs—up to a maximum of 10 puffs. If you still feel unwell after taking 10 puffs, it’s essential to seek emergency medical attention by calling 999.

While waiting for help, sit upright and try to remain calm. This can help keep your airways as open as possible. Avoid lying down, as this can make breathing more difficult. If you have a personal asthma action plan, follow the steps outlined in it for managing an asthma attack.

It’s important to follow up with your GP or asthma nurse after an asthma attack to review your treatment plan. They may suggest adjustments to your medication or provide additional advice on avoiding future attacks.

In conclusion, asthma is a manageable condition, but it requires understanding, monitoring, and proactive treatment to ensure symptoms remain under control. With the right approach, people with asthma can lead full, active lives.
