Kidney Stone Diet: What Is The Kidney Stone Diet?

Kidney Stone Diet, The kidney stone diet is a dietary approach aimed at preventing the formation of kidney stones or managing existing ones. The diet emphasizes adequate hydration through increased water intake to dilute urine and reduce the concentration of minerals that form stones. It also involves regulating your calcium, oxalate, and sodium intake to prevent excessive calcium excretion in the urine.

Kidney stones are solid, crystalline deposits of compounds of calcium, oxalate, and phosphate that form in the kidneys. These tiny, hard stones can be extremely painful when they move through the urinary tract. They are primarily composed of minerals and salts that can accumulate due to various factors, including dehydration, dietary choices, and genetics.

Kidney Stone Diet, According to the data collected from the National Health and Nutrition Examination Survey (NHANES) between 2015 and 2018, it was found that the prevalence of kidney stones in the sample population of 10,521 participants older than age 20 was 11.0%. The 12-month incidence of kidney stones was 2,054 stones per 100,000 adults.

There are several types of kidney stones, but the most common ones (about 70%) are made of calcium oxalate and uric acid. Calcium oxalate stones form when there is an excess of calcium and oxalate in the urine, leading to the formation of crystals. Uric acid stones develop when there is an overproduction of uric acid or insufficient production of urine to dilute it.

Note: As the type of kidney stones and the severity of the condition vary on an individual case-to-case basis, it is important to consult a registered dietitian or your healthcare professional. They would guide you and tailor your diet according to your needs to reduce the risk of kidney stone recurrence effectively.
