Obesity is a condition where a person has accumulated so much body fat that it might have a negative effect on their health causing severe lifestyle issues. If a person’s body weight is at least 20% higher than it should be, he or she is considered obese. (Obesity is defined simply as too much body fat)
Obesity is an increasingly widespread metabolic disorder affecting majority of the world’s population. About 35% of the world’s population is obese. As your body mass index(BMI) rises, so does your risk for coronary heart disease (CHD). Obesity also can lead to heart failure. This is a serious condition in which your heart can’t pump enough blood to meet your body’s needs.
Your chances of having high blood pressure are greater if you’re overweight or obese because the blood pressure rises and stays high over time, it can damage the body in many ways.
Being obese or overweight can also lead to the building of harmful bacterias in the arteries. Eventually, an area of plaque can break out, causing a blood clot to form and if the clot is close to your brain, it can block the flow of blood and oxygen to your brain and cause a stroke. The risk of having a stroke rises as your body mass index increases.
Why Obesity Causes Heart Disease
Previously, it was thought that fat was inert. Now scientists understand that fat, especially intra-abdominal fat affects your blood pressure; your blood lipid levels and interferes with your ability to use insulin effectively (you have intra-abdominal fat if you have a big belly). You use insulin to process glucose derived from food, our body’s primary fuel. If you cannot use insulin properly you may develop diabetes, a risk factor of cardiovascular disease.
An extra-large body needs an extra-large amount of blood. When you gain weight, your heart has to pump more blood than it did before. Instead of beating more often, the heart grows slightly larger so it can move more blood with each beat. It’s like a faucet that’s been opened up a notch. The increased flow often leads to high blood pressure, which is a major cause of heart disease.
Extra weight can also be a sign that you’re hurting your heart in other ways. Many people are overweight because they eat high-fat diets and shun exercise. Other people who gained weight with pregnancy and age have found it difficult to get back on an exercise regimen. No matter how much you weigh, fat-filled foods and lack of exercise can damage your arteries and weaken your heart.
Excess body fat can set off a cascade of other changes in the body that raise the risk of heart trouble. If the fat is distributed in the midsection, the risk is higher; a waist measurement of more than 35 inches in women and 40 inches in men spells an increased risk of cardiovascular disease
Conclusion
Finally, getting into more details, it gives in to hypertension and glucose intolerance. obesity alone is still associated with an increased risk of heart disease.
