Highlights from this day
- gall_bladder_gav — what does homa-ir actually tell you that fasting insulin does not 15:32
- first_month_fi — do you fast for the full 12 hours or is 8 enough 15:37
- mag_citrate — follow up the most useful thing i did was get a full panel before i started. everything since has been comparable 17:32
- mag_citrate — alt and ast coming down as you lose liver fat is common and is a good sign i pay privately for fasting insulin because nobody will order it for me otherwise 19:46
- five_mg_ml — i had a potassium that came back high and the repeat was normal. the tube had been knocked about crp is worth adding if you can, it moves in a useful direction on this 20:12
my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all
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 |
anyone had a result that turned out to be a lab error
an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not, i have it written down somewhere
do you fast for the full 12 hours or is 8 enough

*Janoshik not the other one
ok so crp is worth adding if you can, it moves in a useful direction on this
update from 5 months ago: a1c down, apob unchanged, and i am genuinely annoyed about the apob
not a chat question
ferritin is low, is that the drug or the not eating
good numbers
fast properly or do not bother. an eight hour fast and a twelve hour fast are different tests, thats just me
unrelated but homa-ir is fasting glucose times fasting insulin over a constant. the constant differs by unit system
retest it
see somebody
ferritin and b12 fall quietly when you are barely eating. check them twice a year
apob or ldl, which one are you all actually tracking
thyroid moving slightly is common enough that i would repeat it before doing anything
fasting insulin came back higher than i expected, what does that actually mean
follow up the most useful thing i did was get a full panel before i started. everything since has been comparable
🙏7😂1
the FLOW result is why my nephrologist changed her position on this entirely, your mileage will differ
unrelated but lipase slightly over range with no symptoms, how worried should i be
follow up is there any point getting a1c if i am not diabetic
too early for a1c
if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5, someone check my working
thats a big move
alt and ast coming down as you lose liver fat is common and is a good sign
