GLP-1 therapy: structuring the first weeks
Updated: 2026-09
The first weeks of GLP-1 therapy are the most demanding: side effects occur most frequently, the dose is stepped up, and most questions arise between appointments. Structured documentation is what makes that phase discussable.
The start of GLP-1 therapy is the phase with the most open questions. The dose is stepped up, side effects typically show most clearly in this period, and the body reacts differently from expectations — for better and for worse.
The questions do not arrive during the appointment but between them: at night, after an injection, at mealtimes. By the next appointment they are either forgotten or have grown into a worry nobody could put in context.
At the appointment itself the basis is then missing. How often was nausea present, how severe, and how did it relate to the dose increase? Without documentation the answer is an impression, and impressions are a poor basis for adjusting therapy.
How it works
- 01
Record every injection with date, dose and site
The injection site belongs in there. Repeated injections at the same site can impair absorption — rotation is medically relevant, not cosmetic.
- 02
Record side effects with severity, not just yes or no
A scale makes the course visible. Whether nausea is getting better or worse is the information that counts — not whether it occurred.
- 03
Mark dose changes
Side effects often relate to an increase. Without marked dose changes, that relationship cannot be seen in hindsight.
- 04
Note questions immediately
The question arises at night, the appointment is in three weeks. Unrecorded, it never gets discussed.
- 05
Weigh yourself at even intervals
Not daily. Daily fluctuation says nothing and weighs on you; a fixed weekly rhythm shows the course.
- 06
Generate a report before the appointment
Twenty minutes of consultation time is not enough to reconstruct from memory. A structured report makes that unnecessary.
Why it fits here
The injection tracker records day, time, dose and site with automatic rotation suggestions following FITTER — exactly the details that matter in the early phase.
The AI companion answers questions at any time with full context on the ongoing therapy. That closes the gap between appointments where the questions actually arise.
The clinician report summarises adherence, symptom course and progress in one PDF — for the appointment or an assessment.
FAQ
Does Penday replace medical advice?
No. Penday is a companion and documentation app. For medical questions, speak to your doctor.
Why does the injection site matter?
Because repeated injections at the same site can alter the tissue and impair absorption. Penday suggests rotation automatically.
How often should I weigh myself?
At even intervals, usually weekly. Daily weighing shows fluctuation that says nothing about the course.
What belongs in the clinician report?
Adherence, symptom course with severity and timing, and the progress data. That is exactly what Penday generates in one tap.
Where is my health data stored?
Exclusively in the EU. Database and hosting run in Frankfurt, to GDPR and revDSG standards, with no tracking and no advertising.
