why does diabetes increase the risk for heart disease

The following statistics speak loud and clear that there is a strong correlation between cardiovascular disease (CVD) and diabetes. At least 68 percent of people age 65 or older with diabetes die from some form of heart disease; and 16% die of stroke. Adults with diabetes are two to four times more likely to die from heart disease than adults without diabetes. The American Heart Association considers diabetes to be one of the seven major controllable risk factors for cardiovascular disease. Why are people with diabetes at increased risk for CVD? Diabetes is treatable, but even when glucose levels are under control it greatly increases the risk of heart disease and stroke. That's because people with diabetes, particularly type 2 diabetes, may have the following conditions that contribute to their risk for developing cardiovascular disease. High blood pressure (hypertension) has long been recognized as a major risk factor for cardiovascular disease. Studies report a positive association between hypertension and insulin resistance. When patients have both hypertension and diabetes, which is a common combination, their risk for cardiovascular disease doubles. Abnormal cholesterol and high triglycerides Patients with diabetes often have unhealthy levels including high LDL ( bad ) cholesterol, low HDL ( good ) cholesterol, and high triglycerides. This triad of poor lipid counts often occurs in patients with premature coronary heart disease. It is also characteristic of a lipid disorder associated with insulin resistance called atherogenic dyslipidemia, or diabetic dyslipidemia in those patients with diabetes.

as they relate to diabetes. Obesity Obesity is a major risk factor for cardiovascular disease and has been strongly associated with insulin resistance. can improve cardiovascular risk, decrease insulin concentration and increase insulin sensitivity. Obesity and insulin resistance also have been associated with other risk factors, including high blood pressure. Lack of physical activity Physical inactivity is another modifiable major risk factor for insulin resistance and cardiovascular disease. Exercising and losing weight can prevent or delay the onset of type 2 diabetes, reduce blood pressure and help reduce the risk for heart attack and stroke. It's likely that any type of moderate and/or vigorous intensity, aerobic whether sports, household work, gardening or work-related physical activity is similarly beneficial. For overall cardiovascular health, the American Heart Association recommends: At least 30 minutes of moderate-intensity aerobic activity at least 5 days per week for a total of 150 At least 25 minutes of vigorous aerobic activity at least 3 days per week for a total of 75 minutes Moderate-to high-intensity muscle-strengthening activity at least 2 days per week for additional health benefits. Diabetes can cause blood sugar to rise to dangerous levels. may be needed to manage blood sugar. Smoking Smoking puts individuals, whether or not they have diabetes, at higher risk for heart disease and stroke.

Learn how to. Individuals with insulin resistance or diabetes in combination with one or more of these risk factors are at even greater risk of heart disease or stroke. However, by managing their risk factors, patients with diabetes may avoid or delay the development of heart and blood vessel disease. Your health care provider will do periodic testing to assess whether you have developed any of these risk factors associated with cardiovascular disease. This content was last reviewed August 2015. Diabetes If you have diabetes, you are more likely to develop than someone without diabetes. Diabetes causes high levels of glucose in your blood. This is because of a problem with a hormone your pancreas produces called insulin. Insulin is responsible for moving glucose (a type of sugar) from your bloodstream and into the cells of your body for energy. If there little or no insulin being produced, or your body has become resistant to insulin, glucose stays in the bloodstream and can t move across to your cells to give them energy to work properly. High levels of glucose in your blood can damage the walls of your arteries, and make them more likely to develop fatty deposits ( ). If (the arteries that supply oxygen-rich blood to your heart) you will develop, which can cause and. Type one diabetes happens when your body cannot make insulin. This type most commonly affects children and young adults, and is a result of your body s immune system attacking the cells that produce insulin in the pancreas.

Type two diabetes occurs when your pancreas isn t producing enough insulin or your body has become resistant to the insulin it s producing. Type two diabetes is much more common than type 1 and tends to develop gradually as people get older usually after the age of 40, but more and more people every year are being diagnosed at a much younger age. , especially if you carry weight around your middle a family history of type 2 diabetes. Some ethnic groups have a much higher rate of diabetes - particularly people of and origin. What can I do to reduce my risk of developing diabetes? You can greatly reduce your risk of developing type two diabetes by controlling your weight and doing regular physical activity. The great news is that doing these things will also make you less likely to develop other such as and - as well as being great for your general mental and physical wellbeing.
