How obesity affects people’s health

It is said that obesity is a disease, and obesity is the beginning of many diseases. So what are the effects of obesity on people’s health, and what diseases can obesity cause? Obesity is not only a physical and mental disability due to being overweight, but also has serious abnormal metabolic consequences. Cardiovascular changes imply a marked increase in the incidence of hypertension, but the effects of weight gain on changes in lipid and glucose metabolism are more complex. An analysis of data from the United States found that obesity increases the risk of glucose tolerance and diabetes in the short term. When the body mass index (BMI) exceeds 19, the above-mentioned risk increases progressively with the increase of BMI.

There are some, but not absolutely consistent, relationships between being overweight and diabetes, coronary heart disease, stroke, and some cancers. Clearly, many different factors interact to influence disease patterns in different societies. For example, coronary heart disease death rates are falling in the United States, while obesity rates are rising. In fact, the dietary patterns of U.S. residents have changed significantly, in part because consumer concerns about saturated fat and its effect on blood cholesterol levels have led food companies to successfully reduce the amount of saturated fat in foods, and recently The dietary intake of cis-fatty acids in the U.S. population also encourages the intake of linolenic acid, an unsaturated fatty acid. While the incidence of coronary heart disease continues to decline, obesity rates continue to rise through different mechanisms, such as the gradual decline in physical activity in the United States and the fact that the energy density of the diet does not decline as quickly as the fat content. The increased risk of coronary heart disease due to lower HDL cholesterol and the increased likelihood of obesity-induced hypertension are masking the benefits of lower cholesterol levels. As a result, the American Heart Foundation is concerned that the benefits of dietary changes may soon be outweighed by the effects of rising obesity.
