How does obesity increase the risk of heart and circulatory diseases? Being overweight can lead to fatty material building up in your arteries (the blood vessels that carry blood to your organs). If the arteries that carry blood to your heart get damaged and clogged, it can lead to a heart attack.
How does obesity affect the cardiovascular system?
Obesity has an important role in atherosclerosis and coronary artery disease. Obesity leads to structural and functional changes of the heart, which causes heart failure. The altered myocardial structure increases the risk of atrial fibrillation and sudden cardiac death.
Why is obesity a risk factor for CVD?
Obesity increases the risk for CHD, by increasing the load of the atherosclerotic plaques, characterized by greater macrophage infiltration and plaque instability. The chronic low-grade systemic pro-inflammatory status in patients with obesity seems to be responsible, at least in part, for the increased CHD risk.
How much does obesity increase risk of heart disease?
High blood pressure is usually more frequent in obese people. A 10 kg higher body weight is associated with a 3.0 mm Hg higher systolic and 2.3 mm higher diastolic blood pressure; this increase estimates a 12% increase in coronary heart disease and 24% increased risk for stroke.
Is obesity a cardiovascular disease?
Obesity also leads to the development of cardiovascular disease and cardiovascular disease mortality independently of other cardiovascular risk factors. More recent data highlight abdominal obesity, as determined by waist circumference, as a cardiovascular disease risk marker that is independent of body mass index.
What is a normal heart rate for an obese person?
We categorized all participants into four subgroups: normal weight with heart rate <80 bpm, overweight with heart rate <80 bpm, normal weight with heart rate ≥80 bpm and overweight with heart rate ≥80 bpm.
How is cardiovascular disease caused by smoking?
In addition to permanently damaging your heart and blood vessels, cigarette smoke can also cause CVD by changing your blood chemistry1,2 and causing plaque—a waxy substance comprised of cholesterol, scar tissue, calcium, fat, and other material3—to build up in the arteries, the major blood vessels that carry blood from …

How does obesity affect the digestive system?
Overweight and obesity, particularly abdominal visceral obesity, increased the risk of a wide spectrum of benign digestive diseases such as GERD, BE, erosive esophagitis, NAFLD, gallstones, and pancreatitis and digestive organ cancers such as cholangiocarcinoma, HCC, pancreatic cancer, colorectal cancer, and esophageal …
How does obesity affect the body?
Being obese can also increase your risk of developing many potentially serious health conditions, including: type 2 diabetes. high blood pressure. high cholesterol and atherosclerosis (where fatty deposits narrow your arteries), which can lead to coronary heart disease and stroke.
Can you be obese and not have heart disease?
“Basically, being obese seems to be a ‘solo player’ associated with heart injury—that is, regardless of high blood pressure, elevated cholesterol and diabetes,” says Johns Hopkins cardiologist Chiadi Ndumele, M.D., M.H.S. “Down the road, this can lead to heart failure.”
Does your heart work harder when you are overweight?
The more you weigh, the higher your LDL and triglyceride levels and the lower your levels of beneficial HDL cholesterol are likely to be. Blood pressure rises when the heart has to pump harder to deliver blood to a growing network of arteries in a larger body.
