An injection once a week sounds like something impossible to lose track of. And yet: "did I inject on Thursday or Friday?", "was that already 0.5 mg or still 0.25?", "why did I feel worse after the last dose than usual?". With a therapy that runs for months and changes along the way, memory is not enough. An injection log solves all of this in one go - and keeping it takes a few seconds a week.
Why keep a log when it is only once a week
Precisely because it is once a week. Things done daily become habits; a thing done every 7 days is a perfect candidate for mistakes: the day drifts after a weekend away, the dose changes every few weeks during escalation, and side effects appear with a delay and are hard to connect to anything. A written record turns guessing into facts.
The four things worth recording
You do not need an elaborate form. In practice these are enough:
- Date (and time) - the backbone of the 7-day rhythm and the first thing your doctor will ask about.
- Dose - especially important during the escalation phase. Six months in, nobody can reconstruct from memory when they moved from 0.5 to 1 mg.
- Injection site - without it there is no sensible site rotation, and rotation is what protects you from lumps and uneven absorption.
- How you felt afterwards - one sentence like "nausea in the evening, gone by morning" is enough.
The well-being note is hidden gold
Most GLP-1 side effects follow a repeating rhythm relative to the dose - for many people the first day or two after the injection are the worst. But to see that pattern, you need a few weeks of records. Very practical decisions follow from them:
- moving the injection to Friday so the rough day lands on a quiet Saturday instead of mid-week,
- lighter meals on the day after the dose,
- specifics at the appointment instead of "I feel sick sometimes": "nausea after 3 of the last 4 doses, always within the first day".
What your doctor gets out of it (and you, at the visit)
Decisions about escalating or holding a dose are based on two things: results and tolerance. The log delivers both: the dose history with dates shows the course of the therapy, the well-being notes show how you handle it, and weight tracked by trend shows whether it works. A five-minute conversation backed by data is often worth more than fifteen minutes of reconstructing events from memory.
Paper or phone
Paper works as long as there is one sheet and it is always at hand - in practice it gets lost, stays at home or runs out of space. A note on your phone is better, but you still write and calculate everything by hand. An app closes the loop: it reminds you of injection day, suggests the site, keeps the dose history and builds the summary itself.
In Kalori you log each injection with its dose, site (with a rotation hint on a body figure) and an optional note on how you felt. The dose history forms an escalation timeline, and before a check-up you open a ready summary for your doctor - therapy period, doses, injections and notes in one place. Everything stays locally on your phone, no account needed.
Summary
Date, dose, site, how you felt - four fields, a few seconds after the injection. In return: certainty instead of guessing, side-effect patterns instead of surprises, and concrete data at your appointment. It is the cheapest investment in the whole therapy.
