Do GLP-1 drugs increase the risk of vision loss? Specifically, a condition called NAION: a sudden loss of blood flow to the optic nerve that can cause vision loss. We looked at this in 588,000 people. The answer, in our new @JAMANetworkOpen paper, is yes. 🧵 jamanetwork.com/journals/jaman…
Do GLP-1 drugs cause pancreatitis? Trials have not shown a clear increase. Reports from patients say yes. Observational studies are split. We looked at this in 333,000 people. The answer, in our new @BMJMedicine, is more interesting than yes or no. bmjmedicine.bmj.com/content/5/1/e0… 🧵
Many people don't realize that environmental stressors like air pollution, extreme temperatures, and wildfire smoke increase the risk of kidney diseases. Here is a terrific review in @NatRevNeph led by my mentee turned collaborator Whanhee Lee. nature.com/articles/s4158…
A new finding after stopping GLP-1 drugs in a large cohort with Type 2 diabetes: rapid erosion of CV benefit/protection New @bmj_latest by @zalaly @Biostayan bmjmedicine.bmj.com/content/5/1/e0… See thread: x.com/zalaly/status/…
What happens to the heart when people stop GLP-1 drugs? The short answer: nothing good. New from our team: a study of 330,000+ people in @BMJMedicine 🧵

Best evidence yet that GLP-1 drugs reduce the risk of substance abuse, from >600,00 US Veterans across alcohol, nicotine, opioid, cocaine, cannabis @bmj_latest @zalaly @Miao_Cai_SLU bmj.com/content/392/bm…

📢NEW: In a study of 600,000 people published today in @bmj_latest, we found GLP-1 drugs (Ozempic, Wegovy, Mounjaro) associated with reduced risk of addiction across alcohol, opioids, cocaine, cannabis, nicotine—and 50% fewer substance-related deaths. 🧵 bmj.com/content/392/bm…
We have a big paper dropping at 23:30 GMT/6:30 PM ET. It's not about Long Covid, but I think it is one of the most important studies our team has done. For my Long Covid community: we are working very hard, we have a pipeline of projects, and new work is coming. My team and I are committed to this and will always show up for you. More at 6:30 ET.
We’re recruiting Postdoctoral Fellows (Clinical Epidemiology & Pharmacoepidemiology) ➡️ Details and application via Indeed: indeed.com/job/postdoctor… These positions are hired through our non-profit foundation.
Details & application: indeed.com/job/postdoctor… Rolling review. Apply ASAP! CV, cover letter (w/track preference), 2-3 refs.)
🚨 We're hiring Postdoctoral Fellows! 📷Join a high-performing team to tackle high-consequence public health questions — Long COVID, long-term health effects of acute infections, and more — using large-scale, high-quality databases + cutting-edge causal inference. Two exciting tracks: 🔹 Clinical Epidemiology 🔹 Pharmacoepidemiology Who's ready to make real-world impact? Details and application in link below📷 #EpiTwitter #Postdoc 👇
Honored to speak at @Harvard’s Radcliffe Institute workshop on #LongCOVID. I am energized by our 2 days of brainstorming about the road ahead. The challenges are real, but I’m leaving hopeful. Millions living with Long Covid are counting on our progress—we must keep keep pushing forward. @AzolaAlba @meghanor
It gets wilder. One of the researchers who is helping design this new generation of addictive foods is on GLP-1!!!!!!!
For decades, the junk food industry has deliberately engineered foods to be addictive. Ozempic and other GLP-1 drugs have helped people break free from this cycle. In response, the industry is now searching for ways to counteract the effects of these medications, aiming to design foods that remain addictive even for those on GLP-1. Wild but true. Fascinating piece in NYTimes Magazine. buff.ly/40QHDnk
I talked to Dani Blum from @nytimes about the potential role of GLP-1 drugs on Alzheimer’s disease. They seem promising, but more data is needed for sure. nytimes.com/2025/01/31/wel…
Thanks to @DKThomp for hosting me on his podcast. We talked about the GLP-1 and more. Details in this post below.
New ep: Are GLP-1s "the greatest medical breakthrough of the 21st century"? A new study of 2m Veterans Affairs patients with diabetes found GLP1 use was associated with a reduced risk of: - substance use disorders - psychotic disorders - Alzheimer's and dementia - clotting and
Great coverage by @jwgale in @business Free link here: shorturl.at/4yos8
🚨 ICYMI: Our latest study shows that the popular GLP-1 weight loss drugs (e.g. Ozempic) have broad health benefits — reducing risks of 42 health conditions. They are not without risks — increasing risks of of 19 health conditions. nature.com/articles/s4159…
To the community: A ‘yes’ to supporting Long Covid research is better than a ‘no.’ We will hold him to it—and I stand ready to work with him if he’s serious about advancing research and care for those impacted by Long Covid.
