STEP-HFpEF: semaglutide in heart failure with preserved EF — looking for input

Steady state is the thing most people miss.

Agreed, though "tolerable" needs defining. A dose you tolerate by eating almost nothing is not tolerated, it is being paid for somewhere else — usually in lean mass, sometimes in adherence three months later.

The oral formulation has different absorption behaviour and the dose numbers are not interchangeable, which is worth saying out loud because people…

This is exactly what I could not find anywhere else.

I read this differently from julia.endo, on substance rather than tone. The trial means are being read too generously in this thread. STEP populations were selected, supported, and titrated by protocol, and the real-world curves are consistently a few points worse. That difference is not noise, it is what happens when you remove the study infrastructure.

Prescribed on cardiovascular grounds rather than for weight, and almost everything written for patients assumes the opposite.

Dizziness and cardiovascular risk: I was lightheaded for the first 2 weeks. Root cause was a combination of reduced caloric intake and mild dehydration.

Fix: minimum 80-100oz water daily, don't skip meals even if you're not hungry (eat small protein-rich snacks), and stand up slowly from sitting/lying positions. Also check your blood pressure — GLP-1-induced weight loss can make BP meds too strong, requiring dose reduction.

Moderator note: the sourcing question belongs in the vendor section and has been split out. Report rather than reply if it drifts again.
