There are many factors that can cause heart conditions, which is part of the reason why heart conditions are so common. However, this also means that by controlling the various factors, it is possible to prevent the onset of heart conditions in adults. Obesity is one of the most common causes of heart conditions, especially coronary artery disease. Part of this is because there are more fatty elements in the blood of an obese person, hence increasing the risk of fatty deposits causing blockages in the coronary artery. This may result in a narrowing of the arteries and more strain on the heart. When there is a limitation of blood flow to the heart, ischaemia (a lack of oxygen to the heart cells) occurs. The cells of the heart may start to die due to lack of oxygen, resulting in a heart attack (myocardial infarction), which leads to heart muscle damage and heart muscle death. Obesity can also cause insulin resistance, which can result in diabetes, one of the major causes of heart conditions. Obesity can be caused by one or more of the following factors: Genetic predisposition. Some people are more likely to become overweight or obese due to their genes Overeating, or overeating foods that are high in calories Lack of exercise. The first step in combating obesity is to expend more calories than consumed. This can be achieved through proper dieting and going on a regular exercise regimen.
