Heart rate increase on sema — May 2025

The mechanism that matters here is not stomach emptying, it is central.

I will push back on the "any working dose is fine" framing. The maintenance evidence sits overwhelmingly at the top studied dose, and the extension data shows regain tracking dose reduction rather than tracking stopping. Holding low is reasonable; pretending it is evidentially equivalent is not.

One concrete data point for the thread. Worth knowing that the injection site changes very little. Abdomen, thigh and upper arm are bioequivalent for semaglutide, so a site change is not a plausible explanation for a bad week.

That is the short version; the long version is somebody else's post.

Adding the part of the answer the thread has not reached. The mechanism and the magnitude are separate questions. Agreeing that something happens says nothing about whether it happens enough to act on.

I would rather be corrected than agreed with, if it comes to it.

One thing that is still open after RetaRick_CA’s answer:

How long did you give it before you decided it was working?

OP back with an update, since a thread like this is useless without one.

Following this thread I went back and re-read the extension data properly. The point about trough rather than peak explains the pattern I was seeing on day six, which I had been blaming on the vial.
