my ferritin moved and I cannot work out whether hair loss is why

Side Effects Well Actually ×5 Cold Box ×3

my ferritin moved and I cannot work out whether hair loss is why, which sounds obvious until you try to state the evidence for it.

Most of the common complaints trace back to slowed gastric emptying — early fullness, reflux, nausea after a large or fatty meal. That is also why meal size and speed change the experience more than anything else.

Hair shedding after significant weight loss is a telogen effect that follows the rate of loss. It is not specific to these compounds and it resolves.

Constipation is mostly reduced intake plus reduced fluid, not a direct effect. That is why the boring fibre and water answer keeps working.

Not medical advice, obviously, and nothing here is approved for human use. One person with a spreadsheet.

The effect on gastric emptying is most pronounced early and attenuates with continued dosing, which is the mechanism behind the "it settles at a stable dose" pattern the whole board reports.

Left up. It is a description of one person’s week and it is flagged as such.

Mine settled at week 38 and has not come back since, across two more steps.

A symptom that begins the day after the shot and fades by day four tracks the exposure curve. One that appears at random in week 67 probably does not, and that is worth saying to a clinician rather than to us.

Severe or persistent abdominal pain sits outside the pattern this board can usefully discuss. The honest answer there is that it needs someone who can examine you.

the first fortnight after a step is the worst of it, then it settles

Nothing in this thread is medical advice, including this comment. I am describing a mechanism, not telling anybody what to do about their own week.

Yes — the day-two-to-day-four window is so consistent across this board that it is almost diagnostic.

injection-site soreness for the first eight days after each step, then nothing, every single time. Predictable enough that I started planning my week around it.

I would be careful here. "Everyone gets this" is not true, and it makes the people who get something unusual assume they are fine when they should be asking.

This. A bad fortnight after a step is expected. A bad quarter is a reason to talk to somebody who knows your history.

the injection-site soreness that arrives at week 37 out of nowhere is usually something else

Correction: that is a known effect of reduced intake rather than a direct drug effect. The distinction matters because the fix is different.

How long after a step up did this start?

Bought four different things to fix my early fullness. What actually worked was eating half as fast.

That symptom is not the one being described upthread. Two different things with similar names and the answers are not interchangeable.

u/long_post_larry4 points·1 months ago·edited

That symptom is not the one being described upthread.

blunt_coldbox_2024 is right about the timing. The day-of-week pattern is the diagnostic bit, not the severity.

That symptom is not the one being described upthread.

Disagreeing with this one line: that symptom is not on the wait-and-see list and should not be posted as though it is.

About c/sideeffects

Side-effect experience and management, with a strong bias toward the ones that are common and boring (nausea, constipation, reflux, fatigue, sulphur burps) and a hard line on the ones that are not (severe abdominal pain, persistent vomiting, jaundice, vision changes). This community is not a substitute for urgent care and the mods will say so bluntly.
