Hypoglycemia is defi ned by Whipple's triad or Whipple's criteria consi sting of central nervous system symptoms of neuro glycopenia, a simultaneous low blood glucose level and relief of the symptoms after administration o glucose [5].
Obtaining symptoms from history is critical as most patients will deny the classic sympathetic and neuroglycopenic symptoms of hypoglycaemia and therefore do not satisfy Whipple's triad. Whipple's triad confirms true hypoglycaemia secondary to endogenous hyperinsulinaemia and includes the following criteria: (i) typical symptoms of hypoglycaemia with (ii) a low plasma glucose measured at the time of the symptoms and (iii) relief of these symptoms when the glucose is raised to normal; none of these criteria were met by the patient.
The diagnostic hallmark is the WHIPPLE'S triad Symptoms of hypoglycemia Low blood glucose (40-50 mg/dl) and relief of symptoms after IV administration of glucose The pathognomonic finding is an inappropriately high level of serum insulin during symptomatic hypoglycemia (>5uU/ml)C--peptide levels higher than 2nmol/l have proved valuable in diagnosis.
