Highlights from this day
  • non_scale_win — genuine question apob is the better marker and it is harder to get. i track both because i can only get one reliably 22:18
  • reed_reta — my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all 22:50
  • surpass_two — 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, thats just me baseline, three months,… 22:57

a1c is a ninety day average. retesting at week six tells you almost nothing

LM

a small egfr dip is often dehydration. rehydrate and retest before you panic

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

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

mine did the same

genuine question the most useful thing i did was get a full panel before i started. everything since has been comparable

slightly off topic but ferritin is low, is that the drug or the not eating

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

alt and ast coming down as you lose liver fat is common and is a good sign

nobody here is reading your bloods as a clinician. we are reading them as people who have had a lot of bloods

RR

my numbers: a1c and triglycerides both moved a lot, ldl barely moved at all

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

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

Renal outcomes. The one that changed a lot of nephrologists’ minds.

thats a big move

RR

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