Living with a chronic autoimmune condition like lupus can be challenging enough. But if you start to also experience symptoms of asthma, such as shortness of breath and chest tightness, you may be wondering what this means. Are the asthma symptoms related to lupus? Does lupus cause asthma? Most importantly, what should you do if you start to experience asthma symptoms?
Here’s what to know about the connection between lupus and asthma, and how to treat them simultaneously.
For example, a 2014 study found that people with lupus have a “significantly higher” chance of developing asthma than the general population. Later, a 2020 study found that people who have asthma are also more likely to develop lupus during their lifetime.
The reason for the connection between lupus and asthma
Lupus, known as systemic lupus erythematosus (SLE),
Lupus can affect the lungs as well, causing specific lung conditions to develop. In fact, studies show that between
- lung parenchyma (acute pneumonitis and interstitial lung disease)
- pleura (pleurisy and pleural effusion)
- pulmonary vasculature
- shrinking lung syndrome (more rarely)
Many of the lung conditions commonly associated with lupus share many of the same symptoms as asthma.
How do you know if lupus is affecting your lungs?
If you have any new or noticeable respiratory symptoms, you should contact your healthcare professional and your lupus care team.
The first step in getting treatment for your asthma involves getting a proper diagnosis. Usually, this involves getting screened by a pulmonologist who specializes in asthma. According to the AAFA, screenings for asthma may include:
- spirometry tests: a mouthpiece connected to a machine — called a spirometer — analyses the amount of air you are able to breathe and the flow rate of your breaths
- peak flow meters: hand-held devices that measure the force of air out of your lungs
- FeNO tests: gauge the amount of inflammation in your lungs
- provocation tests: they trigger minor asthma symptoms in people to see if they react and therefore have asthma
Treatments for asthma
Treatments for asthma vary according to how frequently you have asthma attacks and what your asthma is triggered by. Common treatments for asthma, according to AAFA, can include:
- medications that give fast relief for symptoms
- medications that help control symptoms on a daily basis, by decreasing inflammation and other lung issues that contribute to asthma
- biologic treatment, which targets issues of swelling in the lungs
The type of asthma treatment you need will depend on many factors including your asthma symptoms and what your lupus treatment is. Your doctor will help you find the best medication for you. Keep them informed on any changes to your system and how often you use a rescue inhaler.
As of now, it’s not entirely clear how having asthma affects your overall outlook with lupus, as the research is new and evolving.
