Exercise for weight loss increases mortality rate

The mortality rate of obese individuals is significantly higher than that of those with normal weight, and the mortality rate increases with weight gain. Studies have shown that obese individuals have a significantly higher mortality rate from diabetes compared to those with normal weight, at 38.3% (men) and 37.2% (women); followed by patients with cirrhosis, appendicitis, and gallstones, whose mortality rates are approximately doubled in obese individuals; the mortality rates from cardiovascular disease, kidney disease, and accidents are also higher.

hypertension

Obese individuals are more likely to develop hypertension than non-obese individuals. Obese individuals often have increased cardiac output and blood volume, but in obese individuals with normal blood pressure, peripheral vascular resistance is decreased, while in obese individuals with hypertension, peripheral vascular resistance is normal or increased. Hypertension is a significant factor contributing to the high mortality rate associated with obesity.

Coronary heart disease

Obese individuals have a significantly higher incidence of coronary heart disease than non-obese individuals. The reasons include:

① Exceeding the standard weight increases the burden on the heart and causes high blood pressure;

②Obese people often like to eat greasy food and consume too much saturated fatty acid, which promotes the formation of atherosclerosis;

③ Hypertriglyceridemia, hypercholesterolemia, and hyperlipoproteinemia increase blood viscosity and coagulability, making them more susceptible to atherosclerosis, microcirculatory disorders, and coronary artery embolism;

④ Reduced physical activity weakens or reduces coronary collateral circulation. Additionally, obesity increases the body's weight burden, which is also a contributing factor to heart failure in patients with coronary heart disease.

diabetes

The incidence of type 2 diabetes is four times higher in obese adults than in non-obese adults. Obesity is often an early manifestation of diabetes; approximately 40% to 60% of type 2 diabetes patients who develop the disease in middle age or later have a history of overeating and obesity at onset or in the early stages. The incidence of diabetes is directly proportional to obesity. Obese diabetic patients often develop diabetes when they overeat before the onset of the disease, leading to excessive stimulation of β-cells and subsequent compensatory mechanisms.

Exercise for weight loss , cholecystitis, gallstones, and fatty liver

Obesity, digestive and liver dysfunction, high-calorie diets, fatty foods, and lipid metabolism disorders lead to excessive cholesterol reaching saturation, resulting in gallstones, primarily cholesterol stones. The incidence is twice that of individuals with normal weight. Gallstones can cause biliary colic, and secondary infections can lead to acute or chronic cholecystitis. 68%–94% of obese patients have fatty degeneration in their livers, with over half (25%–35%) showing fatty infiltration of hepatocytes. The concentrations of fatty acids and triglycerides in the livers of obese individuals are higher than in those with normal weight.

Infect

Obese individuals have reduced resistance to infection, making them more susceptible to respiratory infections. They have a higher incidence of pneumonia. Skin folds are prone to abrasion, leading to dermatitis, boils, and infections of the urinary and digestive systems. There are reports of appendicitis occurring at twice the rate of normal weight. In cases of acute infection, severe trauma, surgery, and anesthesia, obese individuals have poor stress responses, often resulting in more severe conditions, lower tolerance for surgery and anesthesia, slower postoperative recovery, and increased complications and mortality.

In addition, obese people have slower physical reactions and are more susceptible to various external injuries, accidents such as car crashes, fractures, and serious limb injuries.
