Diabetes
The risk for stroke increases by 1.5 times in diabetic patients than in non-diabetics. This data confirms the status of diabetes concerning stroke. Inability to maintain glucose levels by moderating insulin secretion leads to excess sugar in the blood. Long unchecked diabetes can then damage blood vessels. In the absence of insulin, cellular utilization of glucose is also compromised. A stroke is a likely outcome if the excess sugar damages vessels leading to the brain.
