Definition of Hypoglycemia
|
FED
< 50 plasma < 40 whole blood FASTED < 60 plasma < 50 whole blood |
|
|
Normal hormonal response to hypoglycemia?
|
Catecholamines (rapid release and onset)
Glucagon (rapid R and O) Cortisol (delayed R and O) GH (delayed R and O) |
|
|
Adrenergic Sx's of Hypoglycemia?
|
Weakness
Irritability Sweating Tachycardia Palpitations Tremor N/V Hunger Tingling mouth/fingers |
|
|
Neuro Sx's of hypoglycemia?
|
HA
Hypothermia Visual disturbances Mental Dullness Confusion Amnesia Seizures Coma |
|
|
Non-Insulin Mediate Causes of hypoglycemia?
|
Pituitary or Adrenal Insuff
Ethanol Drugs Tumors Hepatic/Renal Failure malaria |
|
|
Insulin Mediated Causes of Hypoglycemia
|
Meds
Endogenous (insulin secreting islet tumors) |
|
|
Difference between insulin and non-insulin mediated hypoglycemia?
|
Insulin mediated can drop the levels as low as 20-30, non-insulin mediated can only get it down to 40-50
|
|
|
C Peptide and Proinsulin levels for Insulin med, sulfonylurea, and insulinoma induced hypoglycemia?
|
Insulin Meds--> High low C-peptide (cause body isn't releasing it w/ insulin) and normal proinsulin
Sulfonylurea: High C-peptide (cause they cause insulin release from betas) and Normal Proinsulin b/c they only inc secretion not production?? Insulinoma: High C peptide and Proinsulin b/c they're insulin factories |
