Asthma affects about 1 in every 12 people. It is a long-term condition that can cause coughing, wheezing, chest tightness and breathlessness, with symptoms often worse at night or early in the morning. It can develop at any age but it most commonly starts in younger people. Occasionally, asthma symptoms get gradually or suddenly worse and this is known as an 'asthma attack' or 'exacerbation'.
Asthma is caused by inflammation of the small tubes (bronchi), which carry air in and out of the lungs. When a person with asthma comes into contact with something that irritates their lungs (a trigger) their airways become narrow, the muscles around them tighten and there is an increase in the production of phlegm causing symptoms.
Common triggers include:
Medicines – Particularly the class of painkillers called non-steroidal anti infammatories eg. Aspirin and Ibuprofen
Asthma is more common in people who suffer from or who have a family history of atopic conditions such as exzema, food allergies and hayfever.
Asthma can usually be diagnosed by the GP using a few simple tests. It can, however, be more difficult to diagnose in small infants as many other conditions have similar symptoms.
While there is no cure for asthma, there are a number of treatments that can help control the condition. Identifying and avoiding possible triggers is an important means of dealing with asthma.
Inhalers are used to deliver medication directly into the lungs.
There are two main types:
1. Relievers eg. Ventolin, Bricanyl
These are usually blue in colour.
These relieve symptoms quickly making it easier to breathe, but, they do not reduce the inflammation in the lungs.
They are used 'as required' when you feel symptoms.
2. Preventers eg. Becotide, Seretide, Symbicort
These are often brown, red, orange or purple.
They work over time to reduce the inflammation and sensitivity of the airways.
They need to be used regularly, usually twice a day, to be effective.
If your symptoms are not fully controlled with inhalers, your doctor might add additional inahers or oral medication.
totalhealth Pharmacists Advice
Ask your totalhealth pharmacist to review your inhaler technique as a poor technique means you are not getting the full benefit from your medication.
Using a spacer device with your inhaler increases the amount of medication that gets into the lungs making it more effective.
Always rinse your mouth with water after using your inhaler, especially steroid inhalers, to prevent developing hoarseness and oral thrush.
All asthmatic patients are recommended to get the annual flu vaccination. Ask your totalhealth pharmacist if you are eligible for a free vaccination.
