Question
I am 63 years old, weigh about 250 pounds, and am 5 feet 8 inches tall.
I have had
type 2 diabetes
for about 10 years, and I generally keep my blood sugar in check with diet
and medication.
This morning, my blood sugar was 98 mg/dL [5.4 mmol/L], which is fairly
typical. However, I walked downtown to get my mail, and took the long way
back home again. When I returned, I tested my blood sugar, and it was 191
mg/dL [10.6 mmol/L]. I had nothing to drink other than water before going
downtown. I have seen this rise in blood sugar after exercise, often
before. Is this typical? Can I do something about it other than what I'm
doing now?
Answers
One would usually expect exercise to lower blood sugar, but as you found
out, it can also cause blood sugar to go up. During exercise, stress
hormones are released, and that, along with dehydration, can make the blood
sugar go higher. It is frequently advised that exercise should be avoided
if the blood sugar is greater than 250 mg/dl [13.9 mmol/L] or if there are
ketones
in
the urine.
