What's the difference between remission and a cure?
A cure would mean the disease is gone for good—no symptoms, no need for any medication, and no airway inflammation ever again. No study has shown that any treatment can do that [6]. Remission, on the other hand, is a sustained period—usually at least one year—where you have no asthma attacks, no need for oral steroids, minimal symptoms, and normal or improved lung function, even if you still take daily medication [3][5]. Think of remission like a long-term pause, not an erase button. The underlying inflammation can still be present, which is why people in remission can relapse [3].
Who is most likely to achieve remission?
Remission is not equally possible for everyone. The factors that make it more likely include having mild asthma, better lung function at the start, younger age, a shorter duration of asthma, and never smoking or quitting smoking [3]. In one study of people with severe eosinophilic asthma treated with anti-IL-5 biologic drugs, about 21% (11 out of 52) achieved remission after one year [2]. Those who did had higher levels of certain immune markers (like eosinophil peroxidase and IL-5) in their sputum before treatment, suggesting that the right biologic for the right asthma subtype is key [2]. For people with milder asthma, remission rates in the general adult population vary widely—from 2% to 52%—because different studies use different definitions [3]. The takeaway: remission is a realistic goal for some, but not for everyone, and it depends on getting the right treatment for your specific asthma type.
What can you do to improve your chances of remission or better control?
Even if full remission isn't achievable, better control is. The strongest evidence here points to three practical steps. First, use your inhaler consistently. A large Chinese trial of 923 patients found that those who used a mobile app to track their medication had significantly better adherence (66% vs. 59% with good adherence) and better asthma control scores at 6 and 9 months [1]. Second, if you have severe asthma, ask your doctor about biologic therapies. Anti-IL-5 drugs can reduce attacks and oral steroid use enough to meet remission criteria in a subset of patients [2][8]. Third, avoid triggers that worsen asthma over time. One study found that eating four or more servings of cured meat per week was linked to a 76% higher odds of worsening asthma symptoms over seven years, partly through weight gain [7]. While no single change guarantees remission, combining consistent medication, targeted biologic therapy if eligible, and a healthy lifestyle gives you the best shot at long-term control.

Asthma Management Using the Mobile Asthma Evaluation and Management System in China
In a randomized controlled trial of 923 patients with uncontrolled asthma, mobile app management led to significantly better medication adherence (66% vs. 59%) and improved asthma control scores at 6 and 9 months compared to traditional management.
Sputum Type 2 Markers Could Predict Remission in Severe Asthma Treated With Anti-IL-5
In an observational study of 52 patients with severe eosinophilic asthma treated with anti-IL-5 biologics, 11 (21%) achieved remission at one year, and higher sputum levels of type 2 inflammatory markers (e.g., eotaxin-1, IL-5, EPX) predicted remission.
Asthma remission: what is it and how can it be achieved?
This review reports that remission rates in adult asthma populations range from 2% to 52%, and that factors like mild disease, younger age, shorter duration, and non-smoking are associated with remission.
Investigating Adherence to Asthma Management with an Electronic Monitoring System.
In a prospective study of 39 adults using electronic inhaler monitors, average adherence was low (37.3% in the allergy group, 19.3% in the non-allergy group at 90 days), and adherence was negatively correlated with inhaled corticosteroid dose.
Remission in asthma
This review states that several national asthma guidelines now define remission as the absence of exacerbations, no systemic corticosteroid use, and minimal symptoms for at least one year, and that precise phenotyping is essential to achieve it.
Asthma remission: A path to cure?
This review concludes that no intervention has been proven to cure asthma, and that clinical remission—sustained absence of symptoms and exacerbations with or without therapy—is a more achievable goal than cure.
Cured meat intake is associated with worsening asthma symptoms.
In a prospective study of 971 adults, eating ≥4 servings of cured meat per week was associated with 76% higher odds of worsening asthma symptoms over 7 years, with 14% of the effect mediated by body mass index.
Pro: Clinical remission in asthma - implications for asthma management.
This review highlights that biologics have made asthma remission a realistic goal for some patients, but notes the lack of a common definition for remission across studies.
