Highlights from this day
- bac_water_bill — what does homa-ir actually tell you that fasting insulin does not 14:42
- bac_water_bill — what should i get at baseline before i start 17:15
- bac_water_bill — follow up homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system 17:19
- private_script_pri — 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, we shall see 19:40
do you fast for the full 12 hours or is 8 enough
my potassium came back weird and the retest was normal, whats that about
slightly off topic but is a fasting insulin worth paying for privately if my gp will not do it
if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5
nice a1c
📉1
coming back after 14 months, what changed in your numbers
see somebody
if you only get one thing, get a fasting insulin. it is the one that becomes impossible later
get a baseline
private_script_prislightly off topic but is a fasting insulin worth paying for privately if my gp will…
ferritin and b12 fall quietly when you are barely eating. check them twice a year, ill dig out the number
post the numbers
what does homa-ir actually tell you that fasting insulin does not
| 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 |
thats normal
i had a potassium that came back high and the repeat was normal. the tube had been knocked about
the most useful thing i did was get a full panel before i started. everything since has been comparable, ask me again in a month

my alt has come down a lot since i started losing, is that expected
alt and ast coming down as you lose liver fat is common and is a good sign
apob is the better marker and it is harder to get. i track both because i can only get one reliably
baseline, three months, then twice a year is what i settled on
fasting insulin came back higher than i expected, what does that actually mean
update from 4 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob
an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not
not a chat question
retest it
fast properly or do not bother. an eight hour fast and a twelve hour fast are different tests
lab error maybe
coming back to this a single weird electrolyte is very often a handling artefact. retest before you worry
sorry to jump in my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all
too early for a1c

probably dehydration
thats a big move
what should i get at baseline before i start
before after
A1c 6.4% 5.3%
trigs 2.9 1.1
HDL 0.9 1.3
LDL-C 3.4 3.2
apoB 1.09 1.02
ALT 58 24📈4👀16
i pay privately for fasting insulin because nobody will order it for me otherwise
follow up homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system

triglycerides halved. is that the weight or the compound
the most useful thing i did was get a full panel before i started. everything since has been comparable
my b12 is borderline, supplementing or eating differently
anyone have before and after numbers they are willing to post
get fasting insulin at baseline. you cannot go back and get it once you have started
most of the lipid improvement in my panel tracked the weight, not the drug, still working it out
mine did the same
before after
A1c 6.4% 5.3%
trigs 2.9 1.1
HDL 0.9 1.3
LDL-C 3.4 3.2
apoB 1.09 1.02
ALT 58 24is crp worth adding to the panel
❤️2
a small egfr dip is often dehydration. rehydrate and retest before you panic
not a chat question
a1c is a ninety day average. retesting at week six tells you almost nothing
good numbers
the FLOW result is why my nephrologist changed her position on this entirely
get fasting insulin at baseline. you cannot go back and get it once you have started
a1c is a ninety day average. retesting at week six tells you almost nothing, we shall see
is it too early to retest a1c at week 30
nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods
[edited]genuine question crp is worth adding if you can, it moves in a useful direction on this
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, we shall see

*that should say weekly
thyroid moving slightly is common enough that i would repeat it before doing anything
🎉4🤝5
what would make you stop and go and see somebody rather than post here
