Highlights from this day
- night_pin — update on the earlier thing fasting insulin came back higher than i expected, what does that actually mean 20:55
- fasting_insulin — if a result frightens you, that is a conversation with a clinician. we will help you read it, we will not tell you it is fine 21:43
- night_pin — my potassium came back weird and the retest was normal, whats that about 22:24
- night_pin — apob is the better marker and it is harder to get. i track both because i can only get one reliably 22:26
- retention_time — what would make you stop and go and see somebody rather than post here 22:35
most of the lipid improvement in my panel tracked the weight, not the drug
| Test | Why now |
|---|---|
| Fasting insulin | impossible to get a true baseline afterwards |
| Full lipid panel with apoB | the comparison is the whole point |
| HbA1c | 90-day average, so it lags your start |
| CMP + CBC | cheap, and the reference for everything after |
| Ferritin, B12, TSH | these fall quietly on a low intake |
mine did the same
lab error maybe
nice a1c
❤️6👍6
my b12 is borderline, supplementing or eating differently
[edited]ferritin and b12 fall quietly when you are barely eating. check them twice a year, happy to be corrected
i had a potassium that came back high and the repeat was normal. the tube had been knocked about
homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system
a small egfr dip is often dehydration. rehydrate and retest before you panic

sorry to jump in an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not

while im here if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5

post the numbers
the FLOW result is why my nephrologist changed her position on this entirely
*VendorInvestigate not the other one
apob if you can
ferritin is low, is that the drug or the not eating
[edited]📉2👀2
thats a big move
good numbers
retest it
see somebody
not a chat question
too early for a1c
get a baseline
baseline, three months, then twice a year is what i settled on

baseline 58
wk 2 61
wk 4 64
wk 6 67
wk 8 66
wk 10 65 (held dose from wk 7)do you get bloods every 3 months or only when something changes
thats the 90 day thing
Digest for the week of 2025-08-04 has been published.
what does homa-ir actually tell you that fasting insulin does not
is it too early to retest a1c at week 33
thats normal
fasting insulin
nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods
a single weird electrolyte is very often a handling artefact. retest before you worry
do you fast for the full 12 hours or is 8 enough
update from 21 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob
my potassium came back weird and the retest was normal, whats that about

❤️17🙏1😂1
my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all
crp is worth adding if you can, it moves in a useful direction on this
what would make you stop and go and see somebody rather than post here

genuine question thyroid moving slightly is common enough that i would repeat it before doing anything
alt and ast coming down as you lose liver fat is common and is a good sign, not advice obviously
ferritin and b12 fall quietly when you are barely eating. check them twice a year
what should i get at baseline before i start
my alt has come down a lot since i started losing, is that expected
[edited]the most useful thing i did was get a full panel before i started. everything since has been comparable
if you only get one thing, get a fasting insulin. it is the one that becomes impossible later
a small egfr dip is often dehydration. rehydrate and retest before you panic
probably dehydration
