I had 3 blood sugar tests in the last two months. The first fasting test 4 hours after getting out of bed was 114 mg / dL in three days, worried about this result, I went to the lab right after getting out of bed about 40 minutes and the result was 97 mg / dL. Yesterday, when I was admitted to the hospital, I was examined 3.5 hours after getting up and the sugar result was 119 mg / dL. Is it normal? I read somewhere that the liver can release glycogen and hence the results.

The results of the blood glucose level depend on many factors: the meals eaten the day before, in particular their carbohydrate content, physical activity, medications taken, etc.

If the fasting blood sugar test several times (because I understand that you were doing fasting blood glucose test) the result was more than 99 mg / dL, you show abnormal fasting blood glucose.

It would be worth doing random sugar tests at any time after eaten meals and determining glycated hemoglobin. One more blood abnormalities are needed to confirm diabetes in addition to fasting blood glucose.

Criteria for diabetes detection:

Principles of recognizing carbohydrate disorders

Random blood glucose- determined in a blood sample taken at any time of the day, regardless of the time of the last meal. Venous plasma glucose concentration: ≥200 mg / dL (11.1 mmol / L). Interpretation: diabetes(when there are symptoms of hyperglycaemia such as: increased thirst, polyuria, weakness).

Fasting blood glucose- as determined in a blood sample taken 8-14 hours after the last meal.

The concentration of glucose in the venous blood plasma: 70 - 99 mg / dl (3.3 - 5.5 mmol / l). Interpretation: normal fasting blood glucose (NGT)

Venous plasma glucose concentration: 100 - 125 mg / dL (5.6 - 6.9 mmol / L) Interpretation: abnormal fasting blood glucose (IFG)

Venous plasma glucose concentration: ≥126 mg / dL (7.0 mmol / L) Interpretation: diabetes mellitus120 minute glycemia of oral glucose tolerance test

Concentration of glucose in venous blood plasma:<140 mg/dl (7,8 mmol/l) Interpretacja: prawidłowa tolerancja glukozy (NGT)

Venous plasma glucose concentration: 140 - 199 mg / dL (7.8 - 11.0 mmol / L) Interpretation: impaired glucose tolerance (IGT)

The concentration of glucose in the blood plasmavenous: ≥200 mg / dL (11.1 mmol / L) Interpretation: diabetes mellitus
