Eight major hazards caused by obesity

With the gradual improvement of living standards, more and more obese people appear around us. Although obesity will not bring us fatal harm, it can cause some health problems. Obesity is the root cause of many diseases. Obesity is also an important reason for accelerated aging. When some symptoms of obesity appear, it is necessary to control weight in time to avoid more serious impact on physical health.

1. Causes dyslipidemia

Obese people, especially those with abdominal obesity, are more likely than ordinary people to show hypercholesterolemia, hypertriglyceridemia, abnormally elevated low-density lipoprotein and very low-density lipoprotein, while high-density lipoprotein is reduced. The reasons why obese people are prone to hyperlipidemia are not yet very clear. The possible reasons are as follows: one is that they eat too much fat, two is that they store too much fat in their body, three is that hyperinsulinemia can increase blood lipids, and four is that there is a problem with the clearance of blood lipids.

2. Increase cerebrovascular disease

Obese people are prone to high blood pressure, dyslipidemia and diabetes, and obese people with high blood pressure, dyslipidemia and diabetes are more likely to have brain problems. First of all, such people are prone to cerebral atherosclerosis. Their brain blood vessels are hard and brittle, and can easily rupture under the influence of high blood pressure, causing dangerous cerebral hemorrhage and even life-threatening. Secondly, the level of tissue fibrinolysis inhibitor in the blood of obese people is higher than that of ordinary people. This factor makes it difficult to dissolve blood clots once they are formed, so obese people are prone to cerebral thrombosis, also known as cerebral infarction.

3. Increase the probability of high blood pressure

Obesity and high blood pressure are closely related. Among obese people aged 40-50, the incidence of hypertension is 50% higher than that of non-obese people. A moderately obese person is more than five times more likely to develop high blood pressure than a person of normal weight and more than twice as likely as a person of mild obesity.

4. Increase the workload on the heart

Some people have found that the incidence of angina pectoris and sudden death in obese people is four times higher. 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 relaxing to maintain the circulation of blood. Since obese people store too much fat in their blood, the total amount of blood increases accordingly, and the heart will increase its 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, obvious heart failure may even occur.

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 disturbed. Obese people consume more fatty acids, so the liver synthesizes more triglycerides. Large amounts of triglycerides accumulate in the liver. The result is fatty liver.

6. Increased 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 lasts, the greater the chance of developing diabetes.

7. Cause bone and joint diseases

There are three main types of bone and joint diseases that may be caused by obesity: osteoarthritis, diabetic osteoarthritis and gouty osteoarthritis. Among them, osteoarthritis is the most common and harmful. Osteoarthritis caused by obesity mainly affects the knee joints, and secondarily can affect the hip joints and finger joints.

8. Obese people are more likely to develop cancer

According to the results of epidemiological surveys, obese women are more likely to develop endometrial cancer and postmenopausal breast cancer, while obese men are more likely to develop prostate cancer; and as long as a person is obese, both men and women are more likely to develop colon cancer and rectal cancer.
