What this story says

  • Semaglutide, found in Ozempic and Wegovy, was linked to a nearly 40% reduction in asthma attacks.
  • The drug was also associated with a 20% decrease in COPD flare-ups, according to a study.
  • Researchers examined UK medical records of tens of thousands of people taking GLP-1 drugs.
  • Scientists believe anti-inflammatory properties may explain the benefits, but the study cannot prove causation.

A study presented at the European Respiratory Society Congress in Barcelona has linked semaglutide, the active ingredient in the diabetes and weight-loss drugs Ozempic and Wegovy, to a significant reduction in respiratory attacks. Researchers analysed UK medical records for tens of thousands of individuals using GLP-1 drugs. The findings indicated a nearly 40% decrease in asthma attacks and a 20% reduction in COPD flare-ups among those prescribed these medications compared to others taking different diabetes treatments.

Scientists involved in the study suggest that the anti-inflammatory properties of GLP-1 drugs may contribute to these observed respiratory benefits. However, they stressed that the study, based on real-world health records, cannot establish a causal link between the drug and the reduction in attacks. Further clinical trials are required to confirm these findings before GLP-1 drugs could be considered a treatment for lung conditions.

Disagreement on study details

While most reports agreed on the core findings, the specific wording used to describe the study's origin varied. PerthNow, in its full report, stated the findings were presented at the European Respiratory Society Congress in Barcelona, Spain. Science Daily's digest mentioned the findings were presented at the European Respiratory Society. The Chronicle-Tribune, Daily Post-Athenian, Mountain Democrat, Fairfield Sun Times, Maquoketa Sentinel-Press, Rochester Sentinel, News-Herald, The Daily Courier, Southernminn.com, The Daily Herald, The Avery Journal-Times, The Elkhart Truth, The Laconia Daily Sun, and The Herald Palladium digests all stated that injections of semaglutide for diabetes and weight loss also dramatically reduce potentially deadly sudden worsening of asthma symptoms, without specifying where the study was presented.

What the coverage left out

None of the left-rated, centre-rated, or right-rated digests mention the specific names of the researchers or any quoted individuals, such as Professor Chloe Bloom or Dr Alexander Mathioudakis, who were quoted in PerthNow's full report. Additionally, none of the digests mention the specific number of people with asthma in the UK or the proportion experiencing severe disease, details included in PerthNow's full report.

How each side covered it

Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.

Left

11 rated outlets

  • Left-rated reports focused on the link between weight-loss drugs and reduced asthma attacks. Headlines such as "Study finds weight loss drugs linked to 40% drop in asthma attacks" from the Daily Post-Athenian, Fairfield Sun Times, News-Herald, Southernminn.com, and The Avery Journal-Times, as well as "Study finds weight loss drugs linked to 40% drop in asthma attacks" from The Laconia Daily Sun, highlighted this connection. Digests from these outlets consistently stated that injections of semaglutide for diabetes and weight loss also dramatically reduce potentially deadly sudden worsening of asthma symptoms.

Centre

41 rated outlets

  • Centre-rated reports highlighted the specific drug and its impact on both asthma and COPD. PerthNow's full report led with "Weight loss jabs could slash the risk of asthma attacks by almost 40 per cent". Digests from Science Daily, WTVR, KJRH, KBZK, KPAX, KTVH, and KTVQ all mentioned semaglutide, the drug in Ozempic and Wegovy, and its association with nearly 40% fewer asthma attacks and about 20% fewer COPD flare-ups. These reports also noted the findings were presented at the European Respiratory Society Congress.

Right

8 rated outlets

  • Right-rated reports predominantly focused on the reduction in asthma attacks linked to weight-loss drugs. Headlines from the Chronicle-Tribune, Mountain Democrat, Rochester Sentinel, The Daily Courier, The Daily Herald, The Elkhart Truth, and The Herald Palladium all stated "Study finds weight loss drugs linked to 40% drop in asthma attacks". The digests from these outlets consistently reported that injections of semaglutide for diabetes and weight loss also dramatically reduce potentially deadly sudden worsening of asthma symptoms.

Questions about this coverage

How did the left and right cover Semaglutide linked to fewer asthma and COPD attacks in study?
Of the 60 outlets on this story carrying a published leaning rating, 18% are rated left, 69% are rated centre, 13% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 67. The sections above set out what each side emphasised, in its own terms.
Is Semaglutide linked to fewer asthma and COPD attacks in study left or right?
Neither side dominates it. Of the 60 rated outlets on this story, 18% are rated left, 69% are rated centre, 13% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
Is the coverage of Semaglutide linked to fewer asthma and COPD attacks in study biased?
Semaglutide linked to fewer asthma and COPD attacks in study is one event reported by 67 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which outlets covered Semaglutide linked to fewer asthma and COPD attacks in study?
67 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
What did the study find about semaglutide and asthma attacks?
A study presented at the European Respiratory Society Congress found that semaglutide, the active ingredient in Ozempic and Wegovy, was linked to a nearly 40% reduction in asthma attacks. It was also associated with a 20% decrease in COPD flare-ups.
Who conducted the study and where were the records from?
The study was conducted by British scientists who examined UK medical records from tens of thousands of people taking GLP-1 drugs. Professor Chloe Bloom from Imperial College London was a study author.
Can semaglutide be used to treat asthma or COPD?
Scientists believe the anti-inflammatory properties of GLP-1 drugs may explain the respiratory benefits, but the study cannot prove causation. Researchers stressed that further clinical trials are needed before GLP-1 drugs could be considered a treatment for lung conditions.
