National Kidney Month is a time to raise awareness about kidney health and the importance of preventing kidney diseases. One common kidney problem is kidney stones, which can cause excruciating pain and even lead to kidney damage if left untreated. Lifestyle can contribute to the development of kidney stones, and studies show a significant link between obesity and kidney stones.
Obesity is a growing problem in many parts of the world, affecting both adults and children. It occurs when a person’s body mass index (BMI) is higher than 30, indicating an excess of body fat. Obesity has been linked to a range of health problems, including diabetes, heart disease, and high blood pressure. But it can also increase the risk of developing kidney stones.
How obesity can cause kidney stones
So how does obesity contribute to kidney stone formation? There are several ways in which excess weight can affect the kidneys and urinary system. One of the most significant is by changing the way the body processes calcium. Calcium is an essential mineral that plays many important roles in the body, including building and maintaining strong bones. However, when there is too much calcium in the urine, it can combine with other substances to form kidney stones.
Obesity can lead to an increase in the amount of calcium in the urine, which can increase the risk of developing kidney stones. This is because fat cells produce a hormone called leptin, which can increase the amount of calcium in the urine. Additionally, obesity can cause insulin resistance, which can also lead to an increase in urinary calcium.
Another way in which obesity can contribute to kidney stone formation is by increasing the pressure in the abdomen. When a person is overweight, their abdominal fat can put pressure on the kidneys, which can affect the flow of urine and increase the risk of stones forming.
In addition to these factors, obesity can also increase the risk of developing other health conditions that can contribute to kidney stone formation, such as diabetes and high blood pressure. These conditions can affect the kidneys’ ability to function properly, leading to an increased risk of stones.

The links between diabetes, high blood pressure and kidney stones
Overall, it is important for people with high blood pressure and diabetes to be aware of their increased risk of kidney stones and take steps to prevent their formation. This may include maintaining a healthy weight, drinking plenty of fluids, reducing salt and animal protein intake, and following the advice of their doctor.
Higher blood pressure and diabetes can contribute to kidney stone formation in a number of ways. Here are some possible mechanisms:
Increased urinary calcium: High blood pressure and diabetes can cause damage to the small blood vessels in the kidneys, which can reduce their ability to filter out waste products from the blood. This can lead to an increase in the amount of calcium in the urine, which can combine with other substances to form kidney stones.
Decreased urinary citrate: Citrate is a compound that helps to prevent the formation of kidney stones by binding to calcium and preventing it from crystallizing. However, high blood pressure and diabetes can reduce the amount of citrate in the urine, which can increase the risk of stone formation.
Increased uric acid: High blood pressure and diabetes can also lead to an increase in the amount of uric acid in the blood and urine. Uric acid can combine with other substances to form kidney stones, particularly in people who have a genetic predisposition to uric acid stones.
Dehydration: High blood pressure and diabetes can increase the risk of dehydration, which can contribute to the formation of kidney stones. When a person is dehydrated, their urine becomes more concentrated, which can lead to the crystallization of substances that can form stones.
Nerve damage: Diabetes can cause nerve damage, which can affect the nerves that control the bladder and urinary tract. This can lead to incomplete bladder emptying, which can increase the risk of urinary tract infections and kidney stones.
Weight Loss as part of the solution
So what can you do to reduce your risk of kidney stones if you are overweight or obese? The most important thing is to maintain a healthy weight through a combination of diet and exercise. By losing weight, you can reduce the amount of calcium in your urine and decrease the pressure on your kidneys. Additionally, reducing your intake of salt and animal protein and increasing your consumption of water and citrus fruits can also help to prevent kidney stones.
