User :   Ok well i took son in and the GP gave him a oral glucose test and here are
results I got that day
97 Fasting
1 hr 338
2 hr 436
3 hr 225
I got these results when they took it
Here is what the lab report is showing I think there is a mixup
Fasting 97
1 hr 338
2 hr 79During this whole time my son was breathing so fast trying to vomit he was
shaking and he was white as ghost very lethargic.Here is the antibody tests
GAD-65 >30.0 H
C-Peptide 2.1Islet is negativeHe was fasting on all this. The doctor is finally sending me to the ENDO butsays his numbers are so weird and the GAD being high doesn't mean he is diabetic justmeans his sugar was high. I am so lost here. I went in to the doctor today said look at the Lab results and Results that Igot in front of me at the time test was taken. I think a mistake was made ifhis sugar went to a 79 at 2 hrs he would not have been sick like he was. Alsowhen they took his blood sugar I was there and I also wiped his finger andtook it with my meter at same time they did it we got a 12 number diff that
was it. The lab is giving a 300 difference. I asked why he said we have to go
by the lab because blood is diff from arm and finger the lab more reliable. They also made a mistake and gave him 100g not the 75 so not sure what to think. They did apologize said his numbers would still be the same.
This all started because my son was having episodes at school after lunch or breakfast he
would get clammy sweaty and lethargic. His school would send him home. After
the 4th time I said ok off to doctor and we got a blood test done it was a
144 that was like almost 1 hrs after I had to get him from school...Since it
showed HIGH and my sons half brother is Type 1 he figured he would test.
It will be weeks before we get in to the Endogonoligist and we have to wait for the referal first. Can you give me insite here
User :   please. Also I was sent to the Gastrologist after this was done first to rule out Dumping syndrome
My son is 10 he is 53 inch and 53 lbs underweight no matter what we do and the last 6 weeks that this has been happening he has been non stop starving.
Doctor :   Hi
User :   hi
Doctor :   let me read ur query
Doctor :   give me a few minutes
User :   k
Doctor :   OK
Doctor :   From the history, it seems that your son has had high Blood glucose levels
Doctor :   may i know since how longhave they started ?
User :   we just noticed them like 3 to 4 weeks ago when the school kept sending him home
Doctor :   ok
User :   then it was just 144
Doctor :   Have you done the HBA1C test
Doctor :   do u know the levels ?
User :   at home we get a level at times from good at 120 to bad at 187 2 hrs after dinner
User :   his A1c is 5.5
User :   We didnt know anything was wrong till about 7 weeks ago
Doctor :   the post dinner levels can be high due to various reasons
Doctor :   His A1 c seems to be very good
Doctor :   the main issue could be insulin deficiency
User :   we know Pizza 1 slice he cant do makes him hit almost 200
Doctor :   estimation of insulin levels and stimulation tests would help to know better
User :   what does the GAD-65 mean
User :   i posted the resulta of the test they did do and the glucose test
Doctor :   glutamic acid decarboxylase (GAD) is an enzyme
Doctor :   GAD is a major auto-antigen in the process leading to type 1 diabetes
User :   his GAD was >30.0
Doctor :   Persons with type 1 diabetes usually test positive for antibodies to GAD
Doctor :   his current condition can be controlled by proper dosaage of insulin supplemetation
User :   hi c-peptide was 2-1 and the range is 0.8-3.1 so it seems normal range but my doctor said he is way lost he knows the glucose test was awful my son reacted badly
Doctor :   the sweating and other symptoms could be signs of hypoglycemia and keeping a few candies would help to avoid the symptoms
User :   my doctor sent us to a gastro doctor first who is upset because he said my son has the GAD-65 needs a Endo not a gastro doctor he said yes my son is type 1 but the regular doctor said well everyone has a little GAD could mean nothing he would research it
Doctor :   can u confirm the age of your son ?
User :   9 years and 10 months
Doctor :   ok
User :   his half brother is a type 1 he was diagnosed before 1 yr of age he is now 16
Doctor :   THE gastroenterolologist is right
Doctor :   Is your son currently on any medications ?
User :   nope nothing but the doctor said put him on low carb till we see the Endo so his sugars are ok but my son is starving all the time he cant loss weight he is nothing but bones as it is
User :   he only 53 lbs
Doctor :   ok
User :   could take weeks to see the ENDo
Doctor :   he defintiely needs insulin treatment
User :   we had to file the papers for a referal like he did for the GASTRO
User :   His GAD-65 says high what could it mean
Doctor :   which will reduce all his symptoms and help him lead a normal life
Doctor :   this means that he has antibodies that are causing low insulin secretion and reduced response to insulin
Doctor :   insulin supplementation will help him
User :   so does it matter how high or how low it was
Doctor :   not really
User :   i was reading that his c-peptide was normal that means he has insuline wont need it
Doctor :   he will definititely need it
User :   does the glucose test mean anything since I read it shouldnt be used to diagnose type 1
Doctor :   since the A1c is within range, it does not matter much
User :   we already eat real healthy 3 yrs ago i lost 80lbs on weight watchers and i kept it off we eat whole wheat or grain no sugars that why i was suprised by all this
Doctor :   this is nothing related to diet
Doctor :   this is a autoimmune condition, with reduced response to insulin secretion
User :   is it hereditary
Doctor :   and hence additional support to maintain his insulin secretion is needed
Doctor :   Not necessarily
User :   so the GAD is a significat sign even if it says ISLET neg
Doctor :   there are a lot of factors including viral infections, that can cause this type of condtion
Doctor :   it does not
User :   this is so confusing I wish my own doctor would of knows something he sees my son i figured he would be like a pediatric but I guess not
Doctor :   GAD can reduce with further treatment and proper care
User :   so he will always be type 1 or could go away
Doctor :   the condition may stabilise with time
User :   so he might not need insulin forever
Doctor :   and he may improve with the insulin requiremnt coming down
Doctor :   yes that is possible
User :   my son has no fat on his body and he eats 4 meals 2 snacks a day I know something is wrong
User :   so the C-Peptide means nothing then
Doctor :   the C peptide with normal levels, indicate normal insulin secretion
Doctor :   but the issue could be reduced response to the secreted insulin,
User :   yes it was normal
Doctor :   hence additional extraneous insulin, which can resist the insulin antibodies will help in this case
User :   o so more tests. My poor kid is tired of being poked and blood taken he is so upset
User :   he wants to feel better but says he is hungry and low carb diet isnt doing it
Doctor :   I understand the situation and am sympathetic with you and your son
User :   well till i see the ENDO what should i do or watch for.
Doctor :   once insulin is started, his hunger and the weight loss due to glucose loss in urine can be controlled
User :   they never did a urine thing on him
Doctor :   consult your GP if any insulin can be started in the mean time
Doctor :   these tests are needed for proper evaluation and diagnosis
Doctor :   i guess your son has not be properly evaluated
User :   My GP is lost he says he needs to do some research he never even heard of the GAD-65 he ran those test because he called a ENDO and she told him to
Doctor :   But in that case, why did he not send u to a endocrinologist instead of a gi doc?
User :   no clue that is why am upset with him now it will take weeks more like we waited for the gastro
Doctor :   I am so sorry for your troubles
User :   it ok
User :   just wish i knew what was wrong with my son
User :   so he can feel better
Doctor :   i hope everything will be sorted out very soon and you son will be on his way to health
User :   I thank you for your time and advice
Doctor :   feed him well and avoid episodes of hypoglyecmia
Doctor :   with sugar candies as and when needed
User :   i will thank you so much
Doctor :   regular interval feeds will help
Doctor :   you are welcome
