tsh moved slightly, is that a known thing

Highlights from this day
- area_percent — LDL-C can drift either way during active loss. apoB is the number worth watching, and we argue about that weekly 19:16
- area_percent — TSH usually does very little. it is on the baseline list so that when somebody is exhausted in month four there is something to compare against 19:25
- area_percent — a multivitamin is not a measurement 20:27
- a1c_lag — rising ALT while losing weight is unusual enough to take to a doctor 20:36
- a1c_lag — do not test at the worst moment and then draw a conclusion from it. that is the actual lesson of this channel 21:48
genuine question nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods
an isolated lipase a bit over range with no symptoms is usually nothing. lipase with severe pain is not
is a fasting insulin worth paying for privately if my gp will not do it
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
fasting insulin
see somebody
what should i get at baseline before i start
baseline 58
wk 2 61
wk 4 64
wk 6 67
wk 8 66
wk 10 65 (held dose from wk 7)fasting insulin came back higher than i expected, what does that actually mean

crp is worth adding if you can, it moves in a useful direction on this
ALT went from 58 to 24 over five months and nothing changed except my weight
that is the most predictable lab move on these drugs
ALT in this population is largely a liver fat readout. take the fat out and the number follows
same lab, fasting both times
baseline month 5
ALT U/L 58 24
AST U/L 41 22
GGT U/L 67 29
trigs mmol/L 2.9 1.1
HDL mmol/L 0.95 1.28
weight kg 118 96🔥12✅4
those are big moves
triglycerides and GGT move fast. LDL-C often barely budges, and that surprises people
mine went up slightly and i had a small crisis about it
LDL-C can drift either way during active loss. apoB is the number worth watching, and we argue about that weekly
the whole apoB fight is in the #bloodwork archive if you want to lose an evening
what about thyroid
TSH usually does very little. it is on the baseline list so that when somebody is exhausted in month four there is something to compare against
mine was flat the whole way through and my fatigue turned out to be iron
ferritin is the one nobody checks and then wonders why they are tired and shedding
if intake halves, iron and B12 intake halves. that is not complicated
i take a multivitamin
a multivitamin is not a measurement
😄11✅5
ferritin 14 at month four. supplemented, retested, 48 by month eight, fatigue gone
and that is the useful shape of an anecdote. number, action, number
getting ferritin added then
and B12. they usually run together anyway
one more thing on ALT. if it moves the wrong way, that is not a chat problem
rising ALT while losing weight is unusual enough to take to a doctor

coming back to my LDL panic — retested at month nine and it had come down below baseline. it was the active loss
common. measure in maintenance, not mid-descent
so do not test at the worst possible moment
do not test at the worst moment and then draw a conclusion from it. that is the actual lesson of this channel
