Diabetes in Athletes Flashcards
(17 cards)
describe the relative amount of glucagon present in the setting of type 2 diabetes
increased glucagon
when would pre-exercise screening for patients with diabetes be indicated?
when there are symptoms concerning for CVD
what are the three components of pre-screening evaluation for diabetic patients prior to activity?
EKG
Echo
GXT
any random glucose level above what would indicate diabetes?
> 200
what two labs would you consider in addition to A1c and glucose in the eval for possible type 1 DM?
C peptide and autoantibodies
which type of exercise increases glucose level in diabetic patients?
high intensity interval training
how often do patients with type 1 DM need to check serum glucose during activity?
every 30 minutes
for type 1 DM patients with basal insulin pump, by what percentage should you lower the dose 1 hour before and then during exercise?
50%
what glucose range is considered optimal for activity?
126-180
if an athlete with type 1 DM has blood sugar < 90 , how much CHO do you give and then when do you recheck glucose?
give 15g CHO and recheck sugar in 15 minutes
at what blood glucose level during activity should activity be terminated for a patient with type 1 DM?
< 300
at what general time of the day is someone less insulin sensitive?
morning
why is there less insulin sensitivity in the morning?
increased circulating counterregulatory hormones (ex: cortisol)
what general time of day results in higher risk of hypoglycemia in diabetic athletes?
evening - higher risk of hypoglycemia
hba1c should be less than what before the initiation of vigorous activity?
< 9%
if an athletes glucose is > 270 prior to the start of activity what is the next step?
check for urine ketones
