How to navigate the GLP-1 era.

GLP-1 medications slow the stomach, but the trials show the effect is smaller and fades more than most people assume, especially with the long-acting weekly drugs. This guide covers how much slower, whether it lasts, how gastric emptying is measured, how it differs from gastroparesis, and why the "food ferments in your stomach" claim has no evidence behind it.

Missed a few weeks of Wegovy, Zepbound, Ozempic, Trulicity, Saxenda, or a GLP-1 pill? Only four labels spell out when to restart at a lower dose: Wegovy injection after 2 missed weekly doses, Saxenda and Victoza after more than 3 days, and Foundayo after 7 missed daily doses. The rest are silent on long gaps. This by-drug reference separates what each label says from what's left to your prescriber, and explains why going straight back to your old dose is risky.

Novo Nordisk's PAP and Lilly Cares can provide Ozempic or Trulicity free to people who qualify by income and insurance status, but as of September 2026 neither covers Wegovy, Zepbound, Saxenda, or Foundayo. Here's who qualifies, the 2026 income limits in dollars, the documents you need, your prescriber's role, turnaround and renewal, what to do if you're denied, and how PAPs differ from savings cards and direct-pay.

There are now three GLP-1 pills in the US, and they aren't interchangeable: oral semaglutide for diabetes (Rybelsus, now sold as Ozempic tablets), oral semaglutide for weight (the Wegovy pill), and orforglipron (Foundayo). Here's how they compare on approval, how you take them, what the trials found, side effects, cost, and what you give up versus a weekly injection.

Do GLP-1 medications cause depression? The best evidence says no increase in the randomized trials, and in January 2026 the FDA asked for the suicidal-ideation warning to come off the Saxenda, Wegovy and Zepbound labels. Some real-world studies still find a small depression signal, depending on what the drug is compared with, and the months after stopping deserve attention. The drug isn't a depression treatment either. This guide covers the evidence on both sides, what to watch, and when to get help.

Tirzepatide (Zepbound) roughly halved sleep apnea severity in the SURMOUNT-OSA trials, and 42 to 50% of participants reached the trial's definition of resolution. That still left many with apnea, and the trials never tested stopping CPAP for good. This guide covers why you shouldn't retire your machine on your own, how pressure and mask fit change as weight comes off, when and how a repeat sleep test happens, and how an OSA diagnosis affects Zepbound coverage (as of September 2026).
