Diabetes isn’t just about high blood sugar levels. It is a condition which can affect many of your vital organs, including your heart and brain.
Are you at risk of heart disease and stroke?
- Up to two-thirds of people with diabetes have high blood pressure (hypertension) which is considered a powerful risk factor for heart disease.(1) So if you have high BP with diabetes, then your risk is further increased.(2)
- Unhealthy cholesterol levels, obesity, physical inactivity, etc.
- Smoking has been shown to significantly increase the risk of cardiovascular disease.(3)
- Women with diabetes are three times more likely to have heart disease or stroke compared to women without diabetes even if they don’t smoke, have maintained their weight and physical activity levels. (4) Here’s everything a woman with diabetes should know.
- Surprisingly, dangerously low sugar levels (hypoglycaemia) can be a risk factor too.(2)
Watch out for the warning signs
Various CVDs come with their own set of symptoms – from no symptoms to palpitations to chest pain. Some symptoms are obvious and some are not. A weak heart can greatly affect your quality of life. It can leave you fatigued, breathless, non-energetic, and sleepless. A poorly fed brain makes you disoriented and light-headed. Read these expert tips on how to fight tiredness caused by diabetes.
A heart attack may cause pain or discomfort in your chest. Or you may feel the pain or discomfort in your left shoulder, jaw or back. You may also experience nausea, vomiting and breathlessness.
A stroke may leave you numb on the face, hands or leg, most often on one side of your body. You may be confused and find it difficult to speak. There may be a loss of balance or coordination and you may lose consciousness.
How does diabetes really affect the blood vessels and the heart?
If the pipelines supplying water to your house were clogged, your water supply would decrease, right? In the same way, high sugar levels damage the vessels supplying blood to the heart, brain and clog them.
Blockage of blood vessels supplying your heart causes a heart attack. And people with diabetes are at a twofold excess risk for it. Additionally, the heart attack related to diabetes is about a third more fatal.(5) And it isn’t just heart attacks. The damage that diabetes does to the blood vessel in the brain substantially increases your risk of stroke.(6)
You can reduce the risk
How well you manage your diabetes can determine whether or not you are likely to develop cardiovascular disease. Also, you can avoid or delay their development by identifying and managing the risk factors like excess body weight, physical inactivity, smoking, high blood pressure and high cholesterol.
Maintain your blood sugar within the target levels. Exercise regularly. Eat a healthy diet. Maintain low cholesterol levels. Kick the butt. The negative consequences of smoking cannot be stressed enough, especially in people with diabetes. Don’t miss your appointments with your doctor. Get an annual testing done to assess your cardiovascular risk factors.
According to ADA recommendations:(7)
- Aim for weight loss if overweight or obese.
- Reduce sodium and increase potassium intake in your diet.
- Increase your physical activity.
- Moderate your alcohol intake.
- Blood pressure should be checked at every routine visit.
- If you have hypertension with diabetes, the blood pressure target should be 140/90 mmHg.
- If you are at high risk of CVD, a goal of 130/80 mmHg may be set if it can be safely achieved.
- If you are a pregnant woman with diabetes and high BP, the targets of 120–160/80–105 mmHg are suggested.
