Obesity is closely associated with many health conditions and can lead to heart disease, type 2 diabetes , hypertension, and abnormal blood cholesterol. In addition, eating fatty foods without physical exercise causes constant weight gain, a lifestyle that hurts the heart. If you are overweight or obese, you are more likely to suffer from coronary heart disease than people with healthy weight.

Definition of obesity BMI

The diagnosis of obesity is based on the Body Mass Index (BMI), which is defined as body weight (kg) divided by height (m square) i.e. kg/m2. BMI stands for obesity between 30 and 40. If BMI exceeds 40, it is diagnosed as morbid obesity. Scientists and researchers believe that higher BMI increases the risk of heart disease, such as heart disease and depressive heart failure.

Obesity and heart

Excess adipose tissue, especially around the waist, can directly affect the structure and function of your heart, even if you do not have the risk of any other heart disease. In support of this theory, researchers evaluated elderly people of different weight to identify signs of diastomation of left ventricular dysfunction through structural changes in the main pump chamber (left ventricle) of the heart, which prevents the full filling between heart beats. Dysfunction of the left ventricle is asymptomatic, but it represents heart failure that may occur in the future. Heart failure occurs when the myocardial becomes weak or stiff enough to provide enough blood and oxygen for the body.

Depressive heart failure

Left ventricle hypertrophy usually occurs in obese populations and is somewhat associated with systemic hypertension. However, in some cases, even without hypertension, abnormalities in the quality and function of the left ventricle may be associated with the severity of obesity. Obese people are 3 times more at risk of hypertension than normal weight. This can be explained by causality, i.e. lower weight weight has lower blood pressure and heavier weight has higher blood pressure.

In addition to increased cardiac discharge and cardiac output, increasing left ventricular volume and heart wall stress is the most common thing that occurs when there is systemic hypertension. The left ventricle hypertrophy is eccentric, and is usually a diacter dysfunction. In cases of obesity (without systemic hypertension), the volume of the left ventricle usually increases, but the stress on the heart wall is not abnormal. Nevertheless, in obese patients (without hypertension), you can notice an increase in cardiac blood discharge and cardiac output, as well as dialytic dysfunction, these changes in the left ventricle, with sudden death in obese patients Association.


The prevention of obesity-related heart disease is similar to the prevention of obesity itself. Many studies have shown that if you manage yourself to lose weight, you can reduce the risk of heart disease. To prevent heart disease, you need a healthy diet, especially to reduce fatty foods and increase more physical exercise.

Weight loss can be attributed to a simple recipe: daily consumption is more energy than intake from food. As long as weight is controlled, blood pressure will decrease, heart can return to normal size, body can better control loss and cholesterol will decrease.
