Hypoglycemia refers to a syndrome caused by low blood glucose concentration due to various reasons, generally hypoglycemia is defined as plasma blood glucose concentration <2.8 mmol/L or whole blood glucose <2.5 mmol/L. The diagnostic criteria for hypoglycemia in children is 1.11 mmol/L lower than that in adults. The diagnostic criteria for hypoglycemia in children are 1.11mmol/L lower than the adult value. severe and prolonged hypoglycemia can occur with extensive neurological damage and complications. Common symptoms include easy hunger, dizziness, anxiety, fasting hypoglycemia, simple syncope, abnormal sweating, tachycardia, easy fainting, etc. Related tests: 1. Test Measure fasting and episodic blood glucose, blood insulin, C-peptide level, calculate insulin release index (fasting blood insulin/fastening blood glucose), and do starvation test (whether fasting 12~72h induces hypoglycemia) and insulin release inhibition test (static R10.1U/kg/h, compare serum C-peptide level before and after injection) if necessary. 2. Abdominal ultrasound examination 3. X-ray examination Patients suspected of insulinoma can have abdominal CT, especially pancreatic CT, blood sampling from portal vein and splenic vein catheter to determine insulin, and selective pancreatic arteriogram.
Auxiliary examinations.
1. Blood glucose <2.8 mmol/L (50 mg/dl) at the time of attack, with relief of symptoms after glucose injection.
Atypical cases can measure starvation 16 hours blood glucose 3 times and make screening test, such as >3.9mmol/L (70mg/dl) can exclude fasting hypoglycemia, such as <2.
22mmol/L(40mg/dl) for sure diagnosis; 2. 22-3.9mmol/L(40-70mg/dl) for suspected hypoglycemia, connect starvation to 72 hours plus exercise until hypoglycemia attack.
