What Is Asthma? Understanding Symptoms, Triggers and Treatment

Asthma is a long-term condition that affects the airways carrying air into and out of your lungs. These airways become inflamed, and the muscles around them can tighten, making breathing harder. It can affect children and adults, with symptoms that change over time.

With suitable treatment, many people with asthma can sleep comfortably, stay active and continue their everyday activities. Understanding your symptoms and knowing how to use your medicines are important parts of managing it.

Common symptoms include coughing, breathlessness, chest tightness and wheezing — a whistling sound when breathing. Symptoms may come and go, becoming more noticeable at night, early in the morning or during physical activity.

Arrange a doctor’s appointment if these problems keep returning. If you already have asthma, waking at night, struggling with usual activities or needing your reliever more often can mean your treatment needs reviewing.

Triggers vary between people. Dust, pollen, tobacco smoke, air pollution, strong fragrances, cold air and respiratory infections can make symptoms worse. Having allergies or a family history of asthma can also increase the likelihood of developing the condition.

Notice whether symptoms follow particular exposures, such as cleaning a dusty room or spending time around smoke. Identifying your own triggers can help you and your doctor decide which changes are useful.

Exercise can sometimes bring on symptoms, but avoiding all activity is usually unnecessary. If walking, running or playing causes breathing difficulties, ask your doctor how to manage them and stay active safely.

Your doctor will ask about your symptoms, when they happen, any allergies and your family’s medical history. Breathing tests help assess how well your lungs are working and whether airflow improves with treatment.

One common test is spirometry, which measures how much air you can breathe out and how quickly. Your doctor may compare results before and after an inhaled medicine that opens the airways. A peak flow meter may also help track changes over time.

Young children may find these tests difficult. Their assessment can rely more on their symptoms, examination and response to treatment, with follow-up to review the diagnosis.

Inhalers deliver medicine into the lungs. Some medicines relax the muscles around the airways, while inhaled corticosteroids reduce inflammation and help prevent attacks. Controlling this inflammation is an important part of asthma treatment.

Depending on your prescription, you may use separate preventer and reliever inhalers, or a particular combination inhaler that serves both purposes. Not every combination inhaler is suitable for quick relief. Ask your doctor which inhaler to use when symptoms appear and follow the prescribed plan. A quick-relief inhaler that only opens the airways should not be your only asthma treatment.

Correct technique helps the medicine reach your lungs. Take your inhaler to appointments and ask your doctor to watch you use it. Different devices need different breathing techniques, so learning one does not necessarily mean you know how to use another.

Ask for a written asthma action plan. This should explain which medicines to take, how to recognise worsening symptoms and what to do during an attack. Keep it somewhere easy to find and share it with anyone who may need to help you.

Continue treatment as prescribed, including regular medicines when you feel well. If side effects or a complicated routine make this difficult, discuss them with your doctor so the plan can be reviewed.

An asthma attack can develop suddenly or worsen gradually. Get emergency help if breathing is very difficult or your prescribed reliever is not helping. A child who becomes unusually drowsy, confused or develops blue lips needs immediate emergency care.

In India, call 112 for emergency assistance. While help is coming, sit upright and use your prescribed reliever according to your asthma action plan. Do not drive yourself to hospital. Even if you recover from an attack, arrange a doctor’s review within two days to check your treatment and reduce the risk of another one.
