When you’re living with type 2 diabetes, your heart health becomes even more important. It’s natural to feel concerned about your risk of heart disease, but understanding the connection can help you feel more confident and in control. Knowing what you can do to prevent heart disease makes all the difference.
On this page, you will find information on why heart health matters if you’re living with type 2 diabetes, and simple habits that protect your heart and help manage your overall wellbeing. Don’t forget, your cardiovascular system, nervous system and metabolism are interconnected – so caring for one helps care for them all.
Type 2 diabetes affects more than just blood sugar. It can also have a significant impact on your heart and blood vessels. Cardiovascular disease is a leading cause of death for people with type 2 diabetes – that’s why understanding how to prevent diabetes complications and looking after your heart health are so important4.
Let’s discuss why:
Understanding Atherosclerosis
When blood sugar levels stay high over time, they can damage the blood vessels and nerves that control your heart5. This damage makes it easier for fats, cholesterol and other substances to build up in your arteries, creating what’s called plaque. This process, known as atherosclerosis, narrows your arteries and restricts blood flow, increasing your risk of heart attack and stroke5.
Additional risk factors
Additionally, about two-thirds of people with type 2 diabetes have high blood pressure, which further increases the risk of cardiovascular disease6. Diabetes is also linked to a higher risk of developing atrial fibrillation, a condition where the heart beats irregularly or too fast. This means your risk of heart disease is higher, including blood clots, stroke and heart failure1,7. Learn more about cardiovascular disease and type 2 diabetes here.
Atherosclerotic cardiovascular disease (ASCVD) is a condition that affects blood flow to your heart and other vital organs. It develops when fatty deposits gradually build up in your artery walls, forming plaques that narrow the blood vessels3,8.
This build-up happens quietly over time, often without any symptoms. As the arteries become narrower, your heart has to work harder to pump blood, and the risk of a heart attack or stroke increases significantly3. Learn more about ASCVD here.
Heart disease can impact your life in various ways, depending on which part of your cardiovascular system is affected. It may cause6,9:
- chest pain or discomfort
- shortness of breath during daily activities
- fatigue and reduced energy levels
- irregular heartbeat patterns
- a reduced ability to exercise or be active.
For people with type 2 diabetes, heart disease can also make it more challenging to manage blood sugar levels effectively. But remember, many of these risks can be significantly reduced with the right daily habits and medical care6,10.
Everyday heart-smart habits
The good news is that simple, manageable changes can help prevent diabetes complications, such as heart disease and stroke, protecting your heart and helping you feel your best2. Here are some tips to look after your heart health2,6,11:
Most importantly, always speak with your healthcare professional before making changes to your routine or medications. They can help personalise your approach based on your specific risk factors and health goals.
