C-Peptide Level and Diabetes

[Shankarmishra124]

Hi all

I want to know what is c-peptide level. And can it be increased after diagnosis?

I know it is used to decide whether a patient is type1 or type2.

But if one can manage his/her diabetes by strict diet then what is purpose of this test.

Kindly discuss.

Many Thanks.

C-peptide is measured to tell the difference between insulin produced by the body and insulin injected into the body. When the pancreas produces insulin, it starts off as a large molecule. This molecule splits into two pieces: insulin and C-peptide. The function of C-peptide is not known.

The C-peptide level may be measured in a patient with type 2 diabetes to see if any insulin is still being produced by the body. It may also be measured in cases of hypoglycemia (low blood sugar) to see if the person's body is producing too much insulin.

Type 2 Diabetes can be controlled only at the initial stages by diet and exercise.

My question :-

Can C-Peptide level be increased once sugar regulates ?

[Shankarmishra124]

But mine is little low 0.4 at the time of diagnosis.

Normal range is 0.5 to 0.9.

i am maintining my sugar by low carb diet with 1 metaformin along with excercise. I will remove that tab as well.

Please share your knowledge

So in future if i will follow my diet strictly then no need of external insulin for controlling blood sugar.

I am following partial LCHF diet and taking less carbs as i am doing some physical work as well so i need some carb.

Fbs 78

Ppbs 120

@Shankarmishra124,

Thank you very much for initiating this interesting & useful discussion.

Fbs 78 & Ppbs 120 without medicine are fine. These must be the latest results; how much were those at diagnosis of Diabetes?

On what date was the C-peptide (0.4) tested & Diabetes diagnosed?

[Shankarmishra124 in reply to ShooterGeorge]

Sir that C-Peptide level is at the time of Diagnosis i.e on 17 th August.

[ShooterGeorge in reply to Shankarmishra124]

Thank you @Shankarmishra124. Now what you have to watch is the way these parameters respond to treatment.

If you don't mind, one more clarification: under what condition was the C-peptide test done - @FBS or @PPBS?

[Shankarmishra124 in reply to ShooterGeorge]

My fbs was 340 and ppbs was 500 at the time of c-peptide level testing.

[ShooterGeorge in reply to Shankarmishra124]

Thank you for the FBS & PPBS values. Yesterday (11 Dec) what I asked was the time (or condition) at which C-peptide was tested - that is, was it tested with FBS or was it tested with PPBS or was it at some other time.

c-peptide was tested in fasting
