Featured Image

Kidney stones — the small yet painful mineral deposits that form in the kidneys and can cause significant discomfort — are a common urologic condition affecting both men and women. While the formation of kidney stones is influenced by various factors, including diet and genetics, there's growing evidence suggesting a connection between obesity and an increased risk of developing these troublesome stones. Here, board-certified urologists in Jacksonville, FL – Dr. Ali Kasraeian and Dr. Ahmad Kasraeian — discuss the relationship between obesity and kidney stones, outline treatment options, and provide insights into kidney stone prevention strategies.

What are kidney stones?

Kidney stones are solid mineral deposits that form when substances in urine, such as calcium, oxalate, and uric acid, become highly concentrated and crystallize. These stones can range in size from tiny grains to larger, jagged structures, and they can cause intense pain as they travel through the urinary tract.

Is obesity a risk for kidney stones?

While primary obesity itself may not directly increase the risk of kidney stones, several conditions and lifestyle choices commonly associated with obesity can elevate a person's susceptibility to stone formation. Diets high in fat, salt, and sugar, which are often characteristic of obesity, can lead to increased urinary excretion of calcium and oxalate, two components of kidney stones. Additionally, conditions like hyperuricemia, commonly observed in obese individuals, can contribute to the formation of uric acid stones.

Will losing weight decrease my risk of kidney stones?

Yes, adopting a healthier lifestyle and achieving weight loss can potentially reduce the risk of kidney stone formation. By following a balanced diet low in sodium, sugar, and animal proteins, many patients can help prevent the accumulation of stone-forming substances in their urine. Furthermore, maintaining adequate hydration by drinking plenty of water throughout the day can dilute urine and reduce the likelihood of stone formation.

How are kidney stones treated?

When kidney stones do not pass spontaneously or cause severe symptoms, various treatment options are available to help alleviate discomfort and facilitate stone removal. At Kasraeian Urology in Jacksonville, FL, our urologists offer advanced treatments tailored to each patient's unique needs that can help to provide relief from kidney stone symptoms, including:

  • Ureteroscopy: A minimally invasive procedure involving the use of a small scope to locate and remove kidney stones from the ureter.
  • Extracorporeal Shock Wave Lithotripsy (ESWL): This noninvasive approach utilizes shock waves to break down kidney stones, making them easier to pass through the urinary tract.
  • Percutaneous Nephrolithotomy (PCNL): A minimally invasive procedure suitable for large or complex kidney stones, involving the removal of stones through a small incision in the back.

Which kidney stone treatment can I get if I'm overweight?

The most suitable treatment for an obese individual with kidney stones depends on various factors, including the size, location, and composition of the stones, as well as the patient's overall health and preferences. While ESWL may be preferable for some patients due to its noninvasive nature, others may benefit more from PCNL for the effective removal of larger stones. Following a thorough consultation and examination, which may include imaging and other studies if necessary, Dr. Kasraeian will discuss all of your available options and recommend a customized treatment plan that is most suitable for you.

How can I avoid recurrent kidney stones?

Preventing kidney stones may not always be possible, but many people lower their risk by adopting healthy lifestyle habits and dietary modifications. Some of the most effective kidney stone prevention strategies include:

  • Stay hydrated by drinking plenty of water throughout the day
  • Follow a balanced diet low in sodium, sugar, and animal proteins
  • Limit consumption of foods high in oxalate, such as spinach, nuts, and chocolate
  • Maintain a healthy body weight through regular exercise and portion control
  • Consider dietary supplements or medications under the guidance of a healthcare professional to help prevent stone formation

By incorporating these measures into your daily routine, you can potentially reduce the likelihood of developing kidney stones and enjoy better urinary tract health.
