World Kidney Day started in 2006 and celebrated on the second Thursday in March. The mission of World Kidney Day is to raise awareness of the importance of our kidneys to our overall health and to reduce the frequency and impact of kidney disease and its associated health problems worldwide. The 2017 theme is focused on the relationship between obesity and kidney disease.
World Kidney Day - Are Your Kidneys OK?
Kidney Disease & Obesity
Obesity is defined as abnormal or excessive fat accumulation that may impair health. In 2014, worldwide over 600 million adults were obese.
Obesity is a strong risk factor for the development of kidney disease. It increases the risk of developing major risk factors of Chronic Kidney Disease (CKD), like diabetes and hypertension, and it has a direct impact on the development of CKD and end stage renal disease (ESRD): in individuals affected by obesity, the kidneys have to work harder, filtering more blood than normal to meet the metabolic demands of the increased body weight. The increase in function can damage the kidney and raise the risk of developing CKD in the long-term.
Obesity, as well as CKD, is largely preventable. Education and awareness of the risks of obesity and a healthy lifestyle, including proper nutrition and exercise, can significantly help in preventing obesity and kidney disease.
This year World Kidney Day promotes education about the harmful consequences of obesity and its association with kidney disease, advocating healthy lifestyle and health policy measures that make preventive behaviors an affordable option.
Kidney disease is more likely to develop in obese people including in those with diabetes and hypertension.
By 2025, obesity will affect 18% of men and over 21% of women worldwide, and severe obesity will affect 6% of all men and 9% of all women around the world. In some nations, obesity is already present in more than one-third of the adult population and contributes significantly to overall poor health and high annual medical costs.
In the general population, obesity increases the risk of death and contributes to many other diseases such as heart disease, diabetes, hypertension, high cholesterol, fatty liver, gall bladder disease, osteoarthritis, various cancers, mental disorders, and poor quality of life.
A growing body of evidence indicates that obesity is also a strong risk factor for the development of chronic kidney disease (CKD) and end-stage renal disease (ESRD). People who are overweight or obese have 2 to 7 more chances of developing ESRD compared to those of normal weight.
Obesity may lead to CKD both indirectly by increasing type 2 diabetes, hypertension and heart disease, and also by causing direct kidney damage by increasing the workload of the kidneys and other mechanisms.
