Spotlight on stroke in type 2 diabetes: How the risk of these devastating events can potentially be reduced

If you are living with type 2 diabetes, your doctor has probably asked you to make healthy lifestyle choices to help lower your risk of cardiovascular disease—and rightly so! We have previously discussed the connection between type 2 diabetes and heart disease, and this article explains that having type 2 diabetes increases your risk of stroke or heart attack by 2-4 times compared with someone without type 2 diabetes^1,2.

Wondering how to start a conversation with your doctor?

Here's a guide to help you have a good conversation with your healthcare provider about the current state of your type 2 diabetes with regards to cardiovascular risks.

Watch the video below to discover the importance of making lifestyle changes to support your cardiovascular health. In the video, Jean shares her experiences of having a stroke following a diagnosis of type 2 diabetes.

Let’s start with a recap on terminology: cardio means related to the heart, vascular means related to the blood vessels.  

The medical term for a stroke is a cerebrovascular accident³. Cerebro means related to the brain and we know that vascular means related to the blood vessels³. In this blog post, we want to explain why people with type 2 diabetes are at increased risk of suffering a stroke and what can be done to help prevent it from happening, including the role that your diabetes medicine could play¹.

Although your brain is about 2% of your body weight, its intense activity means that it consumes about 20% of the oxygen that enters your body⁴.

Oxygen reaches the brain through the blood, so to ensure normal functioning of the brain, it’s important that its blood supply remains steady⁶.

A stroke can have a significant effect on physical and mental health. It can cause pain, difficulty with movement and pain. In addition, those who have experienced strokes can experience problems with thinking, memory and speach. Some people also experience emotional problems, such as depression⁷.

Unfortunately, when people with diabetes have a stroke, they are at an increased risk of dying or being left with a long-term disability, versus someone without diabetes⁸.

Our blog post on heart disease explains that when there is damage to blood vessels, fatty material (sometimes referred to as ‘plaque’) can build up and obstruct the blood flow in a process known as atherosclerosis. Atherosclerosis can build up for many years without you knowing—it is a silent disease, and a stroke can happen suddenly⁹.  

Uncontrolled blood sugar levels in people with diabetes damage the walls of the blood vessels, thereby speeding up the process of atherosclerosis⁹. People with diabetes also tend to have high levels of the types of fats in their blood that get turned into plaques^10,11.

High levels of sugar in the blood also make blood more likely to stick together to form clots¹². When a clot reaches the brain, it can lead to a stroke⁷. 

Some risk factors for stroke can be kept in check by making your lifestyle as healthy as possible. Here are some things that you can do^13-16:

• Eat a healthy, balanced diet that is low in cholesterol and salt
• Stop smoking
• Only drink alcohol within recommended limits
• Exercise regularly
• Maintain a healthy weight

You can read more about lifestyle changes promoting cardiovascular health in this blog post^1,2,13-16.

You might already know about medicines that work to reduce certain risk factors for cardiovascular diseases, like medicines that reduce cholesterol or high blood pressure. If you haven’t had your cholesterol or blood pressure checked in a while, why not make a note to ask your doctor if it’s worth checking that they are under control? 

As someone with type 2 diabetes, even if your diabetes and all of your other risk factors for cardiovascular disease are well-controlled, you may still, unfortunately, have a higher risk of developing cardiovascular disease than the general population. Only 6% of people with type 2 diabetes are thought to have the risk under control¹⁷.

Talk to your diabetes doctor to ensure you are on the right treatment to help you manage your risks.
