With the development of the world economy and the change of diet structure and habits, the incidence of obesity is becoming higher and higher, which is a new problem brought by modern society. It has aroused widespread concern worldwide and has become a global epidemic.
The incidence of obesity in China has increased year by year in recent years, especially in adolescents. Obesity is related to the occurrence and development of kidney disease, and is a high risk factor of many kidney diseases.
Academician Liu Zhihong mentioned in the latest paper on the epidemiology, pathogenesis and treatment measures of obesity related kidney disease that the risk of chronic kidney disease in obese people increased by 23% compared with normal weight people, and 50% of obese people with type 2 diabetes will enter chronic kidney disease. At the same time, obesity is also a high risk factor for kidney stones and kidney tumors.
On the upcoming World Kidney Disease Day on March 9, 2017, let's focus on obesity again, advocate a healthy lifestyle, prevent kidney disease early and maintain kidney health.
How does obesity lead to kidney disease?
Obesity usually refers to the physical sign caused by excessive accumulation of fat in the body due to energy intake exceeding consumption.
Obesity is defined as the body mass index (BMI) more than 30 kg/m2 (Asian people more than 28). The fat under the renal capsule is tightly wrapped, and part of the fat infiltrates into the renal parenchyma, resulting in mechanical pressure on the renal tissue, leading to local hypoxic injury of the renal tissue.
On the other hand, obese people are often accompanied by hypertension, hyperlipidemia and insulin resistance. These changes can cause changes in renal hemodynamics, resulting in hyperfiltration and hyperperfusion injury of the kidney.
A report from the United States pointed out that obesity related glomerular diseases increased from 0.2% (1986~1990) to 2.0% (1996~2000). The process of kidney injury caused by obesity is very slow, and the clinical understanding of kidney injury caused by obesity is not enough, so the relationship between the two is often ignored.
Clinically, hypertension, microalbuminuria, continuous proteinuria often occur in the early stage, and renal function damage often occurs in the late stage. If not treated in time, uremia will eventually occur, requiring dialysis or kidney transplantation.
How to stay away from obesity and kidney disease?
Preventing obesity through a healthy lifestyle is an important measure to reduce obesity related diseases. It is the responsibility of the whole people to reduce the incidence rate and prevalence of obesity. Poor lifestyle directly affects the progression of obesity-related kidney disease.
Many scholars jointly pointed out that reducing alcohol intake, smoking cessation, increasing dietary fiber intake and strengthening exercise can effectively improve the prognosis of many chronic diseases, including kidney disease. It can be seen that healthy diet, proper exercise, smoking and drinking cessation, cultivating healthy lifestyle, and weight loss are crucial to the prevention of kidney disease.
1. Eat healthily and "keep your mouth shut"
Healthy diet is the basis of kidney protection. Low-calorie and low-fat diet is recommended for obese patients. Get rid of the habit of "eating meat and drinking wine in large bowls" and "reduce the burden" for the kidney. Advocate a light diet, eat more fruits, vegetables and whole wheat, eat less sweets and snacks, balance the diet, and limit alcohol consumption.
Asians consume about 2510kJ (600kcal) of calories per day, of which fat or edible oil should not provide more than 20% - 30% of the total calories, carbohydrates should provide 55% - 65% of the total calories, and protein should not provide more than 15% of the total calories. I would like to remind you that it is also important for the health of our kidneys to eat less overnight vegetables, eat less food with various additives, and reduce the intake of salt, meat and fat.
2. Exercise properly and "step out"
Exercise plays a great role in the prevention and treatment of obesity-related kidney disease. It can improve insulin resistance and impaired glucose tolerance, improve the disorder of fat metabolism. Long-term regular exercise can reduce the release of catecholamine, thus reducing blood pressure.
Research shows that aerobic exercise can significantly improve central obesity, reduce body circulation pressure and reduce intra-abdominal pressure. We recommend that you take aerobic exercise such as fast walking, jogging, cycling, mountain climbing, etc. You can choose moderate intensity of exercise, such as 150 minutes of fast walking per week, and make reasonable adjustments according to your own situation.
3. Stay away from tobacco and food additives and "simplify life"
Smoking not only affects the functions of lungs, blood vessels and hearts, but also quietly poisons the kidneys. All kinds of food additives, preservatives and some drugs, Chinese herbal medicines may have nephrotoxicity, which is especially obvious for the elderly, patients with hypertension and diabetes, greatly increasing the risk of kidney failure. Returning to a simple life and eating more fresh food and low-toxic food are also important measures to maintain kidney health.
Today, our life is getting better and better. The worldwide obesity epidemic is attacking us in various ways, not only the bodybuilding, but also our health. A good lifestyle is the key to protecting the kidney, optimizing the diet structure, strengthening physical exercise, reducing sedentary, avoiding obesity, and protecting the kidney. Let's start with a healthy lifestyle.
