Explain the Cardiovascular disease and stroke?

Obesity may be an independent risk factor for coronary heart disease (CHD) with the degree of obesity being directly proportional to the rate of development of CHD, Even moderate overweight has been shown to increase the risk of CHD. A reduction in weight leads to improvement in cardiovascular risk factors like hypertension and abnormal lipid levels. The blood pressure returns to normal and the lipid profile improves. When the blood vessels of the brain are diseased, they may rupture or there may be inadequate blood supply to brain resulting in a stroke. This may be due to hypertension or fatty deposits in blood vessels of the obese.
