5 Multiple Choice Questions

  1. result of effects of epinephrine (palpitations, tremors, sweating), usually occur following sudden drop in blood glucose levels--catecholamine surge
  2. releases insulin-like protein that causes hypoglycaemia
  3. for diagnosis of hypoglycemia
    1. adrenergic /neuroglycopenic symptoms
    2. blood glucose <50mg/dL at time of symptoms
    3. improvement of symptoms on ingestion of glucose
  4. from accidental or intentional use of hypoglycaemic agents (sulphonylureas / insulin injections)

    diagnose by measuring patient's serum levels of insulin, C-peptide and proinsulin at time of showing symptoms

    show high serum insulin, low C-peptide, low proinsulin levels
  5. occur as result of tumors of α-cells of islet of Langerhans, excessive secretion of glucagon-->secondary diabetes

5 True/False Questions

  1. hypoglycemiausually occurs 6-7 hours after last meal, indicative of underlying disorder, most patients are Type 1 diabetics receiving too large dose of insulin, may be caused by liver disease (more than 80% of liver damage can severely compromise hepatic gluconeogenesis), can be caused by Addison's disease--hyposecretion of cortisol rendering tissues more sensitive to insulin

          

  2. fasting hypoglycemiausually occurs 6-7 hours after last meal, indicative of underlying disorder, most patients are Type 1 diabetics receiving too large dose of insulin, may be caused by liver disease (more than 80% of liver damage can severely compromise hepatic gluconeogenesis), can be caused by Addison's disease--hyposecretion of cortisol rendering tissues more sensitive to insulin

          

  3. insulinomaoccur as result of tumors of α-cells of islet of Langerhans, excessive secretion of glucagon-->secondary diabetes

          

  4. alcohol induced hypoglycemiaconsumption of large quantities of alcohol after fasting or being malnourished-->risk of becoming hypoglycaemic

    large quantities of alcohol produce large amount of NADH-->favor lactate formation rather than gluconeogenesis

          

  5. reactive hypoglycemiamay be caused by drug-induced hypoglycaemia or postprandial hypoglycaemia (within 5h of meal), some individuals manifest transitory hypoglycaemic symptoms after eating a large carbohydrate meal--causes exaggerated transient insulin response, does not usually indicate underlying disorder
