From the perspective of modern medicine, obesity is not a blessing, but a curse. First, it causes cumbersome posture, inconvenience, and psychological obstacles; second, the cost of food, clothing, housing, and transportation increases; and third, it brings all kinds of fatal diseases and even causes early death. Among them, the most harmful effect of obesity is that it can lead to a series of serious complications, such as hypertension, diabetes, dyslipidemia, coronary heart disease, malignant tumors, etc. These diseases are the main killers of human health.
In general, obesity itself is not fatal, but diabetes, coronary heart disease, high blood pressure, etc. that are easily complicated by obesity can really reduce life expectancy. Therefore, we both oppose blind weight loss, and do not advocate "nourishing fat and accumulating fat", but should try our best to make the fat and lean moderate. That is to say, you must calculate your ideal weight according to your specific situation, and then control your weight within the ideal range through diet, exercise, and other measures to ensure a healthy body and truly healthy and longevity.
What are the dangers of obesity?
1. Lead to dyslipidemia
Obese people, especially those with abdominal obesity, are more likely to have hypercholesterolemia, hypertriglyceridemia, abnormally elevated low-density lipoproteins, and very-low-density lipoproteins, while high-density lipoproteins decrease. The reasons why obese people are prone to hyperlipidemia are currently not very clear. The possible reasons are as follows: one is eating more fat, the second is storing more body fat, the third is hyperinsulinemia can increase blood lipids, and the fourth is blood lipids There is a problem with the removal.
2. Increase cerebrovascular disease
Obese people are prone to hypertension, dyslipidemia, and diabetes, while obese people with hypertension, dyslipidemia, and diabetes are more likely to have brain problems. First of all, such people are prone to cerebral atherosclerosis. Their cerebral blood vessels are hard and fragile and are prone to rupture under the action of high blood pressure, causing dangerous cerebral hemorrhage and even life-threatening. Secondly, the tissue fibrinolysis activation inhibitory factor in the blood of obese people is also higher than that in ordinary people. This factor makes it difficult to dissolve the thrombus once it is formed. Therefore, obese people are prone to cerebral thrombosis, which is a cerebral infarction.
3. Increase the probability of suffering from high blood pressure
Obesity is closely related to hypertension. Among obese persons aged 40-50, the incidence of hypertension is 50% higher than that of non-obese persons. A moderately obese person has five times the chance of developing hypertension than a normal-weight person and twice as much as a mildly obese person.
4. Increase heart load
It was found that the incidence of angina pectoris and sudden death in obese people increased by 4 times. This shows that obesity will definitely increase the burden on the heart and cause heart damage. The heart of a normal human body is like a water pump, constantly contracting and expanding, maintaining the circulation of blood. Because obese people have too much fat stored in the blood, the total blood volume has also increased a lot, and the heart will increase the contraction force accordingly. When the heart is overwhelmed, it can no longer pump blood effectively, causing blood to accumulate in the cardiovascular system. In severe cases, even obvious heart failure occurs.
5. Cause fatty liver
About half of obese people suffer from fatty liver. The liver is where triglycerides are synthesized, but there is not much extra space in the liver to store them. In obese people, the balance between triglyceride synthesis and transport is out of balance. Obese people consume more fatty acids, so the liver synthesizes more triglycerides. A large number of triglycerides accumulate in the liver. As a result, fatty liver is formed.
6. Increase the risk of diabetes
Obesity is one of the important risk factors for diabetes. Among patients with type 2 diabetes, 80% are obese. Moreover, the longer the obesity occurs, the greater the risk of diabetes.
7. Causes bone and joint diseases
There are three main types of bone and joint diseases that may be caused by obesity: osteoarthritis, diabetic osteoarthropathy, and gouty osteoarthropathy. Among them, osteoarthritis occurs the most and the most harmful. Osteoarthritis caused by obesity mainly affects the knee joint, followed by hip joints and finger joints.
8. Obese people are prone to cancer
According to the results of epidemiological investigations, obese women are more likely to develop endometrial cancer and postmenopausal breast cancer, and obese men are more likely to develop prostate cancer; and as long as they are obese, both men and women are more likely to develop colon cancer and rectal cancer. The more severe the obesity, the higher the prevalence of the above cancers.
