What level blood sugar is stroke?

Elevated blood glucose is common in the early phase of stroke. The prevalence of hyperglycemia, defined as blood glucose level >6.0 mmol/L (108 mg/dL), has been observed in two thirds of all ischemic stroke subtypes on admission and in at least 50% in each subtype including lacunar strokes.

Can blood sugar levels cause stroke?

Over time, excessive blood glucose can result in increased fatty deposits or clots in blood vessels. These clots can narrow or block blood vessels in the brain or neck, cutting off the blood supply, stopping oxygen from getting to the brain and causing a stroke.

Why diabetes causes stroke

At what sugar level is diabetic coma?

A diabetic coma could happen when your blood sugar gets too high -- 600 milligrams per deciliter (mg/dL) or more -- causing you to become very dehydrated. It usually affects people with type 2 diabetes that isn't well-controlled.

What is greatest immediate danger for a person with diabetes?

Hypoglycemia is a blood glucose level less than 70 mg/dl. This is the greatest immediate danger to students with diabetes; sometimes it cannot be prevented.

What is a diabetic shock?

Diabetic shock – a state of severe hypoglycemia, or extremely low blood sugar – can be extremely serious among people suffering from diabetes, even those who are closely managing their blood sugar levels. Shock usually happens in patients with Type 2 diabetes.
