Obesity not only affects the beauty of the body, but also causes inconvenience to life. More importantly, it is easy to cause a variety of diseases and accelerate aging and death. Such as high blood pressure, diabetes, etc., these diseases can be our health killers. Although obesity is not fatal, diseases caused by obesity can really affect life expectancy.
Looking at the people around you, you will find that most obese patients have more or less heart problems, and excess fat tissue in the body needs to consume more oxygen. The heart must provide more blood oxygen to the adipose tissue.
In addition, the more fat accumulation in the arteries, the worse the arterial function, the thickening of the blood vessel wall, and the decrease of blood flow, which not only increases the burden on the heart, but also increases the risk of thrombosis and deterioration of the systemic blood circulation. Obese people are 10 times more likely to have atherosclerosis than healthy people.
A new study by the University of California, Los Angeles, found that fat people had an average of 8% less brain tissue and 16 years of premature aging than normal-weight people.
Generally, the brain tissue of overweight people is 4% less than normal people, and premature aging is 8 years. The poorer the brain, the worse the cognitive function of the brain. Scientists believe that this is related to the deterioration of white matter around the nerve fibers in the brain. This affects the nerve fiber transmission signal.
In fact, obesity can also damage the skin. Obesity can lead to changes in hormones in the body, which in turn leads to skin pigmentation of acanthosis nigricans, thickening of rough and other skin disorders such as stasis and dermatitis. It can also cause venous dysfunction, poor blood flow and increased risk of foot ulcers.
The study found that compared with normal weight, abdominal obesity had a two-fold higher risk of lung function damage, and the incidence of respiratory diseases such as COPD and sleep apnea was higher.
The researchers said that obese people’s tummy assembly limits the diaphragm, which in turn increases the difficulty of lung expansion. Excessive fat increases the inflammatory response in the body and damages the lungs to some extent. Usually abdominal obesity means that the male waist is larger than 40 inches (about 101.6 cm).
The study found that obesity is associated with most cancers but is most associated with colon cancer. In obese people, there is a strikingly proportional relationship between the incidence of bowel cancer and the degree of obesity.
The reason is that excessive intake of processed meat and red meat increases the risk of intestinal polyps (early signs of colon cancer). Another reason is the high level of insulin-related growth factors in insulin or blood. However, the specific mechanism by which these factors increase the risk of colon cancer is not fully understood.
Obesity is a very harmful thing, and everyone does not want obesity to appear, but sometimes even if we are fully prepared, obesity will still come. In fact, this is because we do not understand the causes of obesity. As a result, I believe that after understanding the factors that cause obesity, everyone can reasonably avoid it.
