Can Ozempic prevent cancer? Several large studies suggest it might. But the excitement is running ahead of the evidence. In @theconversation.com, I explain what the evidence actually shows and why these studies are so easy to misread. theconversation.com/can-ozempic-...

Can Ozempic prevent cancer? A doctor explains why the headlines are easy to misread
Several studies suggest GLP-1 drugs may lower cancer risk. But that benefit may be due to the patients themselves: those who are healthier, wealthier and with better access to care.

The finding that stopping GLP-1 drugs can undo years of heart protection is resonating. Coverage from CNN, TIME, USA Today, CNBC, Gizmodo, and others. What 3 years of continuous treatment builds, ~1.5 years off the drug can erase.

What happens to the heart when people stop GLP-1 drugs? The short answer: nothing good. 333,000+ adults. 3 years. 16 treatment scenarios. New in @bmjmedicine.bsky.social 🧵

For your weekend reading: I wrote about what our BMJ findings mean for addiction — why GLP-1s work across every addictive substance, and how these drugs seem to quiet cravings the same way they quiet food noise. @us.theconversation.com theconversation.com/glp-1-drugs-...
theconversation.com
GLP-1 drugs may fight addiction across every major substance, according to a study of 600,000 people
GLP-1 drugs are the first medication to show promise for treating addiction to a wide range of substances.

New in the BMJ: Our study of 600,000 people found GLP-1 drugs associated with 50% fewer substance-related deaths, 39% fewer overdoses, and reduced addiction risk across alcohol, opioids, cocaine, cannabis, and nicotine. www.bmj.com/content/392/...

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!!!

For decades, the junk food industry has deliberately engineered foods to be addictive. GLP-1 drugs have helped people break free from this cycle. The industry is now searching for ways to undo the effects of these meds, aiming to design foods that remain addictive for those on GLP1. buff.ly/40QHDnk

Ozempic Could Crush the Junk Food Industry. But It Is Fighting Back.
As revolutionary new weight-loss drugs turn consumers off ultraprocessed foods, the industry is on the hunt for new products.

GLP-1 drugs are revolutionizing the way we think about obesity. It is a chronic disease (like high blood pressure), and might actually be a form of food addiction. One reason these drugs are so effective in treating obesity could be that they address the underlying addiction.

Alzheimer, addictions, dépression… les effets bénéfiques de l’Ozempic et des médicaments apparentés
Les médicaments GLP-1 sont efficaces pour traiter le diabète et l’obésité. Ils pourraient l’être aussi pour lutter contre de nombreuses autres affections. Néanmoins, des effets indésirables existent.

I talked to Dani Blum from @nytimes.com about the potential role of GLP-1 drugs (Ozepmic and similar drugs) on Alzheimer’s disease. They seem promising, but more data is needed. www.nytimes.com/2025/01/31/w...
