Can Insulin increase Blood Pressure and cause a Stroke? Posted: 08-28-06 16:28pm
We battle Mom's low blood pressure. But I
found her on the floor recently and 911
was called. They suspected a stroke as her
BP was 209/92, slurred speech, confusion,
sweats. It is never that high! I suspect
now she could have taken 55 units of
Humalog the previous night instead of 55
units of Humulin 70/30. Could that have
caused this serious episode? Thank you

Insulin has nothing to do with high blood
pressure and the possibility of a brain
stroke. High blood pressure can cause a
brain stroke if an arterial blood vessel
in the brain can’t handle the pressure
and ruptures because of it. Then, a brain
hemorrhage occurs. The opposite event is
also possible. A brain stroke (from
whatever cause) can increase intracranial
pressure in the head due to a
bleeding/infarct and the surrounding brain
tissue edema. Increased intracranial
pressure causes high blood pressure by a
reflex mechanism. A CT-scan is necessary
to conclude or exclude a brain insult.
