Hello,
I signed up here today because I saw this specific thread.
My summary: Since January, I have noticed high blood sugars
33 years old. BMI 21. No diabetes in my family, not even distant relatives (but both of my parents have thyroid diseases). "Normal" fasting glucose and hba1c, yet
HIGH postprandials > 200 occasionally, depending on what I eat.
Ran from doc to doc but no one takes me seriously because hba1c is "fine", despite my high postprandials. Today for instance I ate a mixed meal (rice, fish, broccoli, sweet desert) in order to prove the point to my doctor (normally I eat low carb and manage to keep my blood sugar within ranges below 120, with an occasional 140 here and there )........ and I hit 239 at 1 hour and was still at 215 at 2 hours, 82 at 3 hours. THIS doctor finally said ok, we'll do an oGTT but don't worry, it's not diabetes (because he looked at the hba1c - see below). Huh? I thought any reading above 200 measured more than once IS Diabetes.
Since no doc took me seriously, I checked for LADA since I read that that is most likely with my stats ("young age", normal weight, and no diabetes in the family).
Ordered a whole range of blood panels out of my own pocket (
fasting for 12 hours) and here are the results (lab reference in brackets):
Glucose: 92 mg/dl (< 100)
Hba1c: 5.2 % (< 6.2 %)
Hemoglobine 13.9 g/dl (12.0 - 16.0)
Hematocrit: 41.1 % (36 - 47)
(so no "false low" hba1c due to anemia or something)
ICA: negative (< 3.125 JDF-Units)
GAD-65: < 0.3 U/ml (<1.0)
IA-2: < 0.8 U/ml (<1.0)
IAA: <0.4 U/ml (<0.4)
(so far, so good. Now for the bad stuff):
C-Peptide basal: 1.3 ng/l (1.4 - 5.4) !!!!
Insulin basal: 1.9 mU/l (5.0 - 30.0) !!!
HOMA-IR: 0.4 (< 2.5)
I have tons of other values too but I don't think they would be too interesting or matter much here. Lipids are all perfect. Kidney and liver too.
So, if I interpret above numbers correctly:
no Insulin resistance (no Type 2?). No antibodies (no Type 1?). But low C-Peptide and Insulin - what is wrong with me? Am I such an early LADA case that my antibodies are not detectable YET? I read that 20% of T1s don't ever show antibodies anyway, so that could be it, right?
Why is no doctor taking me seriously and telling me I don't have diabetes? Most of all,
is anyone here who had low C-peptide and Insulin, yet NONE of the 4 antibodies, and still turned out to be LADA? It's frustrating trying to catch something early on (because I want to act preventive now rather than waiting for complete detoriation)....and doctors don't take you seriously just because it hasn't been in their medical books yet.
Anyone here who started out as early as me?
