Hypoglycemia diagnosis

Hypoglycemia is difficult to diagnosis. When healthy persons including woman and child when the empty stomach vein blood plasma glucose value is lower than 2.8mmol/L(50g/l), although not clinical symptoms, should also diagnose is Hypoglycemia. The empty stomach venous blood glucose is higher than when 3.9mmol/L(70mg/dl) may remove Hypoglycemia; Empty stomach vein blood plasma glucose when 2.8~3.9mmol/L(50~70mg/dl) may prompt the hypoglycemia possibility, some experts think the child and the baby, when the blood sugar level is lower than 2.8mmol/L(50mg/dl), should observe carefully. When the blood sugar level is lower than 2.2mmol/L(40mg/dl), only then may diagnose and the treatment. Otherwise, the senior citizen vein blood plasma glucose value in 3.3mmol/L(60mg/dl) often may have the hypoglycemia symptom. Therefore the normal person blood sugar maintains at the ideal level, in 24 hours fluctuate the scope very little to surpass 2.2~2.8mmol/L(40~50mg/dl), this kind of glucose's stability are adjust through each kind of hormone. When the glucose uses, the ingestion and (either) produces is not balanced may have hyperglycemia or Hypoglycemia.

Hypoglycemia is confirmed diagnosis by following tests:

1. Laboratory Tests. Attack measured fasting and blood glucose, plasma insulin, C-peptide levels, insulin release index (fasting plasma insulin / fasting glucose) and, if necessary, make hunger test (12 ~ 72h whether fasting-induced hypoglycemia) and the release of insulin suppression test (static drop R10.1U / (kg/h), compared before and after injection of serum C-peptide levels).

2. Peritoneal B-ultrasound, if necessary, to make. Site can be found in the pancreas tumor, less than 1cm are easily missed diagnosis, CT and MRI as a reliable.

3.X-ray examination. Patients suspected of insulinoma, do abdominal CT, in particular pancreatic CT, portal vein and splenic vein catheter measured blood insulin, selective pancreatic arteriography.
