Often thought of as a condition you get when you're a child, asthma can develop at any age.
People are often surprised to find out they've developed asthma later in life, but it’s not unusual. It's known as 'late onset asthma' or 'adult onset asthma'.
If you think you have asthma it's very important to make an appointment with your GP or an asthma nurse as soon as possible. Untreated asthma may be life threatening.

Common signs and symptoms of asthma include coughing, wheezing, tightness in the chest and shortness of breath.
A trigger is anything that starts your asthma symptoms or makes your asthma symptoms worse. It’s possible to have several triggers and sometimes it’s difficult to work out what your triggers are.
In adults, the symptoms of asthma are less likely to be triggered by allergies, such as house dust mites, animals and pollen. If you’ve developed asthma as an adult, it may have been caused by something at work. Occupational asthma or work-related asthma can develop very quickly or take weeks, months or years to develop.
Symptoms may be triggered by:
- flu, colds or other viral infections
- heightened emotions, from laughing to getting stressed
- hormonal changes
- some medicines
- certain foods
- cold air and temperature changes
- cigarette smoke, chemical fumes or air pollution.
Avoiding your individual triggers, when it’s possible, can help reduce the risk of an asthma attack.
Asthma can be complex and take time to diagnose. This is because everyone’s asthma is different. Getting a diagnosis for a child, for instance, is different from getting a diagnosis for an adult. And asthma symptoms can ‘come and go’ so it can be tricky for a GP to see the full picture.
Also, the reasons for breathlessness can vary and in adults, especially older adults, it can be more difficult to tell the difference between asthma and other conditions that cause similar symptoms such as pneumonia, heart disease, obesity, a panic attack, and chronic obstructive pulmonary disease (COPD).
If you tell your GP you think you may have asthma, they will probably start by asking questions - about your personal and family history, symptoms, workplace environment and lifestyle, for example. You may be asked to do a breathing test (lung function test) which measures how your lungs are working, and keep peak flow recordings.
To confirm you have asthma a number of other tests may be recommended – your GP or asthma nurse will decide which tests are suitable for you. Unless you're unwell with symptoms your GP will wait for test results before prescribing any treatments. This is to make sure you get the right medicines for you and that you're not taking medicines unnecessarily.
If you are having symptoms the GP may prescribe you asthma medicines before a diagnosis is confirmed to help you stay well. But they will still need to arrange tests to confirm asthma at a later date.
It's important to get a confirmed diagnosis. If you have asthma and it’s not diagnosed or managed properly, it can make it even harder for your lungs to work and, over time, make your lung function even worse.
If you’re having symptoms your GP may decide to give you one or more asthma medicines to see if they help. This is known as a ‘trial of treatment’. The GP or nurse should still make some measurements of breathing tests/FeNo before and after the trial. If you respond well to the trial of treatment (if your symptoms start to get better), it's a good indication you could have asthma. You may be asked to reduce or stop the medicines to see if symptoms come back. But the best way to confirm or rule out asthma is with asthma tests.
Depending on the results, your GP may need to investigate other possible causes for your symptoms. If it’s unlikely you have asthma, you may be referred to a specialist.
If at any point during the trial of treatment your symptoms get worse, contact your GP or asthma nurse immediately.

What happens after diagnosis?
If you’re diagnosed with asthma, the good news is there are lots of effective medicines available to help manage your symptoms.
When you’re first diagnosed, you may need to see your GP or asthma nurse a few times to check how you’re feeling and monitor your treatment. One of the most important things you can do during this time is to download a written asthma action plan and fill it in with your GP or asthma nurse. You're four times less likely to need to go to hospital with asthma if you have one. Once you’ve filled it in, you can then take it to each appointment so it’s always up-to-date.
Once you feel as though you’re on top of your symptoms and you’re in a good routine with your medicines, it’s important to book an asthma review at least once a year – even if your symptoms are well managed and you’re feeling well. This is so your GP or asthma nurse can check your medicines in case the doses need to be changed. It’s also a chance to talk about your triggers, lifestyle and any other factors that may affect your asthma, such as hay fever.
If your GP or asthma nurse thinks you may have severe asthma (which affects around five per cent of people with asthma), the usual asthma medicines may not work well for you and you will be referred to a specialist for more tests to find out if you have the type of asthma that can be classed as ‘severe’. If you do, you will work closely with your team of health professionals to find the best combination of treatments for you.
If you’re worried about anything to do with your diagnosis, speak to your GP, asthma nurse or pharmacist. You can also call our Helpline on 0300 222 5800 (9am – 5pm; Monday - Friday) and ask our asthma nurse specialists anything about your symptoms or treatment, your lifestyle or the way you’re managing your asthma. The better understanding you have of the condition, the better position you’ll be in to work with your GP or asthma nurse to manage your asthma well.
We produce award-winning materials to help people with asthma understand and manage their condition more effectively. Our resources have been co-created with people with asthma, developed using the most trusted evidence, and evaluated by healthcare professionals.
