It causes the air passages to rapidly narrow (bronchospasm), leading to shortness of breath. This can be accompanied by the production of sticky phlegm.Asthma often, but not always, begins in childhood. Asthma symptoms can range from mild to severe. If not treated, inflammation can cause permanent changes to your lungs.What causes asthma?It isn’t fully understood what causes someone with asthma to have airways that can narrow. You’re more likely to get asthma if you have any of the following risk factors:You have eczema or allergies, including hay feverYou have a family history of asthma, eczema or allergiesYou had respiratory (lung) infections as a babyYou were born prematurelyYou have been exposed to cigarette smoke, including in the wombYou are exposed to high levels of air pollutionWhile the cause of asthma isn’t fully known, many people with asthma have what are known as triggers. These are substances or situations that bring on asthma symptoms. They can include pollen, dust mites, smoke, exercise and stress.What are the symptoms of asthma?There is a range of possible asthma symptoms, with each person getting a different set. Symptoms can include:CoughCough is a common symptom of asthma. It often happens at night or after exercise and sometimes comes with mucus. An asthma cough won’t respond to antibiotics unless associated with an infection.WheezingWheezing is a whistling noise caused by breathing out through narrowed airways. In asthma, this usually occurs when your symptoms worsen, and you might also have a tight chest.Difficulty breathingWhen you have asthma, you should not feel breathless under normal conditions. If something triggers your asthma and your airways begin to narrow, you may feel short of breath.Chest tightnessThis can happen if your asthma gets worse or during an asthma attack. It’s a feeling like a band being tightened around your chest.FatigueIf your asthma is not completely controlled, you may find that you are being woken up at night by your symptoms.Rapid breathingOne of the indications that you asthma might be getting worse, possibly leading to an asthma attack, is faster breathing (increased respiratory rate).As with many other signs, if they do not resolve rapidly when taking your reliever inhaler, you should seek medical attention.AnxietyAnxiety is more common if you have asthma, and your healthcare team may ask you if you ever feel anxious. You may find chest tightness and difficulty breathing can make you agitated, especially if you’re having an asthma attack.Workout fatigueIf you have asthma, especially exercise-induced, you may find yourself especially tired after a workout. If you find that you’re getting progressively more exhausted after exercise, it may be a sign that your asthma is not as well controlled as it could be. If this is the case, you should talk to your doctor about ways to better manage your asthma.Asthma attack signsAn asthma attack is when your symptoms worsen and aren’t controlled by your usual medication. Signs of an asthma attack can include:Severe coughingWheezing not relieved by inhalersShortness of breathChest tightnessFatigueA severe asthma attack can be life-threatening. You should call 999 for an ambulance immediately if your symptoms are getting rapidly worse despite using your inhalers or if you get any of the following:Blue or grey discolouration of the lips, face or nailsExtreme difficulty breathingUnable to complete sentencesConfusionExtreme anxiety or agitationRapid pulseWhat are the types of asthma?There are several different types of asthma. Your doctor will be able to tell you if your asthma fits into one of these groups.Allergic asthmaThis is asthma triggered by an allergy (for example, pollen). In this case, it’s essential to avoid your trigger as much as possible and always carry your prescribed inhalers.Non-allergic asthmaIn this case, there is no allergic trigger for asthma. This condition often develops later in life.Occupational asthmaThis is asthma directly related to exposure to a substance in your work environment. Triggers can include dust from flour and latex.Cough-variant asthmaIn this type of asthma, coughing is the main or only symptom. You should visit your GP for any persistent cough to determine the cause.Nocturnal asthmaThis is when your asthma symptoms are much worse at night. Ensuring you have the correct medications and taking them at the right time helps ensure a good night's sleep.How will my asthma be diagnosed?If you’re experiencing breathlessness, cough or other respiratory symptoms, your GP will want to find out as much as possible. That includes when it started, what brings it on, and if any other symptoms are associated with it.The doctor will examine you, including listening to your chest with a stethoscope. They’ll probably ask you to perform a breathing test called a ‘peak expiratory flow test’ or ‘peak flow’ to see if you have evidence of narrowed airways.They may also ask to perform spirometry, which involves exhaling from a full breath through a device called a spirometer.Even once you’ve been diagnosed, if you’re experiencing repeated wheezing, coughing or shortness of breath, you should speak to your GP or asthma nurse and re-evaluate your asthma management plan.##product-carousel:braun-pulse-oximeter-yk-81ceu,omron-c28p-nebuliser,omron-miniair360-miniair360p-e-portable-mesh-nebuliser,aerochamber-plus-device-standard##Why is my asthma not getting better?If you notice your asthma symptoms become worse or the following describe you, your asthma may not be well controlled:Difficulty sleeping because of your asthma or coughSymptoms like coughing, wheezing, shortness of breath or a tight chestYour asthma interferes with your normal everyday activitiesAnother sign that your asthma may not be under control is suddenly needing to use your reliever inhaler more often than usual.When it's not asthmaOccasionally other medical conditions can have similar symptoms to asthma.
