Obesity Fuels Chronic Kidney Diseases
A health survey conducted by the Dubai Health Authority in collaboration with the Dubai Statistics Centre revealed that 11.9% of people in Dubai suffer from obesity. The growing issue of obesity plays a key role in reducing people’s life expectancy and causes several severe health conditions.
Obesity is a combination of factors including high calorie intake, lack of exercise, sedentary lifestyle practices etc. Obesity is now a growing phenomenon across the globe and is one of the key factors responsible for a number of chronic diseases including kidney diseases.
Obesity causes mortality due to diabetes, stroke, conditions of the heart, certain cancers etc. However, a rarely discussed and rather unknown fact is the link between obesity and its consequences on the kidney.
Obesity is directly linked to chronic kidney diseases (CKD) and its progression because obesity facilitates diabetes and hypertension which are the two common causes of kidney conditions. Body Mass Index (BMI) is the most used parameter to determine obesity, however, the waist circumference or waist to hip ratio is a better indicator of chronic health conditions.
Obesity influences chronic kidney conditions in two ways; an obese individual is at a higher risk of diabetes and high BP which are causative factors of CKD. On the other hand, an obese individual’s kidneys will have to function much harder for the process of filtration in order to meet the demands of a person with higher BMI. An obese individual can also be at the risk of having kidney failure.
Obesity is reported to be one of the leading causes for chronic kidney conditions and end-stage renal disease (ESRD). The end stage of chronic kidney conditions is called ESRD when they kidneys are no longer able to function to its ability on a daily basis.
The most common kidney damaging conditions are;
Polycystic kidneys: is a condition where a person has multiple cysts in the kidneys causing it to enlarge. This condition is generally a birth defect.
Kidney stones: or Nephrolithiasis are hard mineral deposits made of acid salts that form inside the kidney or urinary tract. People who take medicines for gout are at a risk of kidney stones, dehydration is also a cause for the condition.
Proteinuria: a condition developed when there is abnormal protein in the urine. Albumin is a protein found in the human blood because the body needs it to fight infections, build muscle etc. The function of the human kidney is to filter the blood and remove things that aren’t required by the body. There will be an underlying cause for proteinuria which needs evaluation.
Focal segmental glomerulosclerosis: is a condition caused by scarring of the kidney. This condition may be caused due to primary or secondary reasons. The primary reason of scarring being no obvious cause, the secondary reason may be caused by another pre-existing condition, a prescribed drug, obesity or any other underlying condition.
Glomerulonephritis: is a condition causing inflammation of the Glomeruli (the kidney cell). This can lead to Hypertension, blood in the urine and proteinuria. In certain cases, this can progress to acute kidney failure.
It is extremely important to keep your kidney healthy for it to function to its full capability. Your blood sugar needs to be in control, failing which will cause diabetes. Keeping your body and mind fit by staying active helps in keeping the body fit and healthy.
Water is key to prevent kidney conditions, drinking water flushes out the toxins from the kidneys and reduces the chance of kidney stones. Smoking is a causative factor for a number of health conditions, and it is always best to quit it. Certain over the counter medications may also cause kidney damage. This does not mean that they should not be taken at all, however, a physician must be consulted before self-medication.
Routine medical checks are important to screen for chronic kidney conditions and for those who aren’t aware of the health risks they have. An obese individual must be aware of the positive impacts of losing weight which will include prevention and reduction of various chronic health conditions like diabetes, hypertension, heart diseases and kidney conditions.
Every year, March 9th is celebrated as World Kidney Day with the aim of educating people about the importance of kidney health and the diseases associated with the kidney. This year World Kidney Day goes by the theme of ‘kidney disease and obesity’ because obesity is a potential risk factor for kidney diseases which is an unknown fact.
Obesity and chronic kidney conditions are both preventable, upon undertaking healthy lifestyle practices. This kidney day lets us all promise ourselves to ensure adopting and advocating healthy lifestyle practices to beat the harmful health consequences of obesity and related kidney diseases.
