get fasting insulin at baseline. you cannot go back and get it once you have started

FA

ferritin and b12 fall quietly when you are barely eating. check them twice a year

            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

thats a big move

is it too early to retest a1c at week 26

right so apob is the better marker and it is harder to get. i track both because i can only get one reliably

baseline  58
wk 2      61
wk 4      64
wk 6      67
wk 8      66
wk 10     65   (held dose from wk 7)

crp is worth adding if you can, it moves in a useful direction on this
if your glucose is in mg/dL the divisor is 405. if it is mmol/L it is 22.5

FA

my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all, thats one data point

if you only get one thing, get a fasting insulin. it is the one that becomes impossible later

most of the lipid improvement in my panel tracked the weight, not the drug

i pay privately for fasting insulin because nobody will order it for me otherwise

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

TS

fasting insulin came back higher than i expected, what does that actually mean

lab error maybe

thyroid moving slightly is common enough that i would repeat it before doing anything

my alt has come down a lot since i started losing, is that expected

right so update from 3 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

*VendorInvestigate not the other one

FA

a small egfr dip is often dehydration. rehydrate and retest before you panic, thats one data point

            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

tsh moved slightly, is that a known thing

a single weird electrolyte is very often a handling artefact. retest before you worry

📈7

right so i had a potassium that came back high and the repeat was normal. the tube had been knocked about

DD

update on the earlier thing anyone have before and after numbers they are willing to post

DD

what does homa-ir actually tell you that fasting insulin does not

the FLOW result is why my nephrologist changed her position on this entirely, ill dig out the number

TS

while im here baseline, three months, then twice a year is what i settled on

is crp worth adding to the panel

slightly off topic but lipase slightly over range with no symptoms, how worried should i be

SA

fast properly or do not bother. an eight hour fast and a twelve hour fast are different tests

SA

fasting insulin

update on the earlier thing apob if you can

get a baseline
