In-depth analysis of the link between obesity and various diseases: health risks such as diabetes and cancer.

Does obesity lead to a variety of diseases?

The answer is yes. Obese individuals have disordered metabolism of both sugar and fat, including decreased glucose tolerance and increased blood lipids. Therefore, they are prone to hyperlipidemia, hypertension, arteriosclerosis, coronary heart disease, myocardial infarction, cerebral hemorrhage, and are also susceptible to gout and gallstones. Women may experience decreased menstruation, amenorrhea, and infertility. Statistics show that obese individuals have a 2-5 times higher incidence of coronary heart disease than underweight individuals, and an even higher incidence of diabetes, 6-9 times higher. Excessive fat accumulation under the skin in obese individuals places an extra burden on the body, increasing oxygen consumption by 30-40% compared to normal individuals. Due to the increased respiratory and physical workload, obese individuals are prone to shortness of breath, and their feet are more likely to become flat-footed, increasing walking difficulty. It is particularly important to note that obesity may lead to certain cancers.

Is there a link between obesity and cancer?

According to statistics from an insurance company, among 100,000 deaths in people of normal weight, 111 died from cancer; among those under 15% of the standard weight, only 95 died from cancer; and among those over 25% of the standard weight, a staggering 143 died from cancer.

Middle-aged women who are overweight are more prone to endometrial adenocarcinoma and breast cancer.

Excessive fat intake is a major cause of obesity, and excessive fat is a carcinogenic factor. Studies have shown that high fat intake, especially animal fat, affects the composition of intestinal flora and bacteria, causing changes in bile acid metabolism; the metabolic products of fat and protein, especially unsaturated fatty acids, can be carcinogenic under certain conditions. Excessive fat intake, especially cholesterol (which mainly comes from animal foods), can also cause endocrine disorders. Too much fat affects cell membrane permeability, allowing carcinogens to enter cells and reducing cellular immune function. This reduces the body's anti-cancer ability and promotes the growth of cancer cells. Therefore, people welcome "being thin in old age"—of course, this refers to a normal weight, not weight loss caused by disease.
