A survey on the weight of American men and women revealed that 40% of Americans are obese. This suggests that the nation's weight will continue to increase in the coming days.
Obesity is a common metabolic disorder. When the calories we consume exceed those we burn, the surplus is stored as fat in our bodies. Excessive fat accumulation eventually leads to obesity.
Multiple factors contribute to obesity:
First, obesity may stem from a congenital slow metabolism, where the rate of substance synthesis exceeds the rate of breakdown, leading to fat cells spreading throughout the body.
Second, obesity may result from acquired conditions, such as overeating. Excessive consumption of sugary and fatty foods leads to fat distribution throughout the body, with larger fat cells forming.
Third, obesity may result from hyperfunction of the adrenal cortex, leading to excessive sebum secretion. Affected individuals often exhibit enlarged faces, necks, and torsos, while limbs remain relatively lean.
Fourth, obesity can stem from hypothyroidism, typically manifesting as water retention-type obesity.
Fifth, obesity may stem from diminished sexual function. It can lead to loss of sexual function or reduced libido in daily life, often manifesting as breast and genital enlargement in affected individuals.
Obesity poses significant health risks, affecting not only physical well-being but also mental health. Obese individuals often face societal discrimination, and without proper psychological adjustment, they may develop mental health disorders such as depression or psychosis. In severe cases, this can lead to fatal outcomes.
Obesity poses multiple health risks:
First, medical studies indicate that obese women face heightened risks of endometrial and breast cancer, while obese men are more susceptible to prostate cancer. Compared to individuals of normal weight, the severity of obesity correlates directly with increased cancer incidence.
Second, obese individuals accumulate excessive fat not only subcutaneously but also within visceral organs and blood vessels throughout the body. Consequently, they face heightened risks of various vascular diseases that threaten both health and life.
Third, obesity can trigger diabetes. While obesity isn't the direct cause of diabetes, it significantly contributes to its onset. Numerous medical studies confirm that the higher the degree of obesity, the greater the incidence of diabetes. In many countries, diabetes is the most common obesity-related disease, and two-thirds of diabetes patients are obese.
Fourth, the excessive weight of obese individuals places additional strain on joints and the musculoskeletal system. Prolonged overburdening can lead to chronic conditions, causing joint changes in obese patients.
