There is an intimate connection between obesity and a number of health conditions that, with enormous potentials, can lead to heart diseases, type 2 diabetes, high blood pressure, unusual blood cholesterol. Furthermore, that you gain weight ceaselessly may result from a heart-damaging lifestyle surrounding eating fat-laden foods and hidden from exercise.
The Definition of Obesity
Obesity is diagnosed according to BMI (Body Mass Index). BMI is defined as weight (in kilograms) divided by height (in meters square kg/m2). ABMI between 30 and 40 means that you are obese, and if your BMI exceeds 40, you are diagnosed with morbid obesity. Scientists and researchers currently assume that higher BMI can increase risks of heart diseases such as heart attack and congestive heart failure.
Obesity and Heart
It is suspected that extra fat tissue, particularly surrounding the waist, can directly affect your heart structure and function even without any other risks of heart disease. In order to support this theory, researchers made an assessment on older individuals of different weights in search for signs of left ventricular diastolic dysfunction. This condition is distinguished by changes to the structure of the heart’s main pumping chamber (left ventricle), which prevent it from filling sufficiently between beats. Left ventricle diastolic dysfunction displays no symptoms, but it can signify a heart failure in the future. Heart failure happens when the heart muscle becomes so weak or stiff that it cannot supply a sufficient amount of blood and oxygen that the body requires any more.
Congestive Heart Failure
Left ventricular hypertrophy usually occurs among obese people, and can comparatively be linked to systemic hypertension. Nevertheless, in some cases, there still, without hypertension, arouse abnormalities in left ventricular mass and function which can have a connection with the severity of obesity. Obese people are at about three times higher risk of hypertension than normal-weight people. This can be explained by the cause-and-effect relationship in that the lower weight, the lower blood pressure, and the higher weight, the higher blood pressure.
Besides increased stroke volume and cardiac output, increased left ventricular volume and wall stress are things that commonly occur when you have systemic hypertension. The hypertrophy of the left ventricle is very odd, and diastolic dysfunction is usual. In the presence of obesity (without systemic hypertension), left ventricular volume is usually raised, but wall stress is not abnormal. Notwithstanding, among obese patients (with the absence of hypertension), you can notice increases in stroke volume and cardiac output as well as diastolic dysfunction. There is a connection between these changes in the left ventricle and sudden death in patients with obesity.
The prevention of heart disease related to obesity is pretty similar to the prevention of obesity itself. Many studies unveil that you can reduce the risk if you can manage to carry out even a moderate weight loss. Hence, to prevent heart disease, you need a healthy diet. In particular, reduce fat-rich foods, and help yourself participate more physical activity.
By doing this, your blood pressure will drop; the heart can return to its normal size; the body can make better use of insult, cholesterol will decrease.
