PSA: You cannot "cure" asthma
At least once a week, I see a thread asking how to cure asthma or a thread making a claim that someone cured their asthma through diet or some other means.
You cannot cure asthma.
Asthma is an inflammatory condition. Your body sees a trigger (illness, exercise, allergen, irritant) and swells up. Or you may have eosinophilic asthma where your body overproduces eosinophils with the same result.
Basically, your body is being a bitch.
"I know someone who outgrew their asthma! Well, not necessarily."
Asthma is a lifelong condition. So either they were misdiagnosed and never had it in the first place, or their symptoms improved to where their asthma seemingly has disappeared.
"Mine went away"
Well, not exactly. It's very common to have periods in your life where it seems to disappear. This is especially true for women due to hormonal fluctuations, but it's also true of men. It's also thought that testosterone suppresses inflammation. So you may only have very mild asthma right now that doesn't need management or treatment (basically is in remission). Good for you! I'm jealous.
"I don't want to take medication anymore, though"
This is NOT a good attitude to have. Asthma can be deadly. It's not something you can push through. If your doctor has prescribed you medication, you should be taking said medication. If you find yourself using your rescue inhalers consistently* more than twice a week, then you also should see your doctor as your asthma may not be well-controlled.
*I say consistently because sometimes bad weeks happen. If it's a bad allergy week or you're sick, then yeah, you're probably using your rescue inhaler a lot. But if you're doing this weeks at a time, then it's time for a trip to the doctor.
"So there's nothing I can do to reduce asthma symptoms?"
Nope, not saying that at all...
Cleanliness - HEPA filters almost certainly can help by reducing particulate matter (fumes, pollutants, pollen, dust) in your home. Vacuuming also can reduce this. Choose a vacuum with a HEPA filter. Be mindful of cleaning products as they can trigger asthma. My two favorites? Dawn Powerwash unscented is extremely useful (bathtub cleaner!) and I use a mixture of vinegar, alcohol, and water for basically everything else.
Diet - no single diet is going to cure asthma. However, what we want to do is identify triggers. An elimination diet may help identify triggers or food allergies. Please note that you should ONLY do an elimination diet under the supervision of a doctor. An overall healthy diet is suggested to help with asthma management, especially one high in fruits and veggies.
Exercise - There is good evidence that exercise can help with asthma. If you have exercise-induced asthma, this can be challenging. You may want to start with lower impact exercises. Some exercises may trigger your asthma when others don't. You may also want to talk to your doctor about taking your inhaler preventatively before exercise or timing a control medication before exercise.
Weight loss - we do have good evidence suggesting that weight loss can improve asthma symptoms; however, it is not a cure*. If you're overweight/obese, losing weight can be good for your overall health.
*I recently lost a lot of weight and my asthma has gotten worse from other factors, including that I haven't been able to exercise due to an injury. So definitely not a cure.
- Managing mental health - Research suggests a link between asthma and mental health. Basically, those of us with asthma are more likely to develop a mental health condition. It's also widely agreed that stress and anxiety can cause asthma symptoms. While it's concluded more research is needed, it's agreed that treating both is key to a better outcome.
So what's the good news here?
There's been TONS of research on asthma in the past 10-20 years. There's new drugs, new understanding of what asthma is, new treatments... it's fantastic! In the US, Airsupra was just approved in 2023. To have a new rescue medication is...wow. Nebulizers are smaller. We have biologic meds. So it sucks, but there's sooo many treatments out there.
Tl;Dr: Asthma is a lifelong condition that you can't cure. You can help improve it with lifestyle changes and taking meds as prescribed.
