A major kidney function is to remove waste products from the body.
The organ is also important for production of red blood cell, hormones regulating blood pressure and Vitamin D.
Kidney stones can be due to metabolic disease resulting from a:
a) lack of enzyme breakdown upon waste products;
b) build-up of any of the following: calcium, ammonia, uric acid, or cysteine.
Kidney stones can be described as ‘calcium oxalate’ stones (90%) or uric acid stones (10%).
Uric acid stones are a by-product of purines metabolism which can be caused by a diet high in meat.
Primary hyperparathyroidism is a feature in 15% of patients with kidney stones, more common in women than men (3: 1 ratio) between 40 to 80 year old age range and a cause of hypercalciuria (ie., elevated calcium levels in urine).
An Ayurveda perspective is that stones form due to inadequate water consumption.
