Just as Donguibogam stated thousands of years ago that the kidney governs the bones, modern medicine is also scientifically uncovering how closely the kidney and bone health are linked. Although they might seem like two unrelated organs at first glance, the kidney actually acts like a conductor playing a decisive role in keeping our bones strong.
One of the most important links is the activation of vitamin D. The vitamin D we get from sunlight or food is in an inactive state. When this inactive vitamin D passes through the liver and reaches the kidney, it is finally converted in the kidney into calcitriol. This active vitamin D plays a key role in promoting calcium absorption in the intestine and helping calcium deposit properly into the bones. If kidney function declines, vitamin D activation cannot take place properly, so no matter how much calcium you consume, bones inevitably become weaker.
In addition, the kidney is deeply involved in the actions of parathyroid hormone and calcitonin, which regulate the balance of calcium and phosphate in the blood. When calcium levels in the blood drop, the kidney stimulates the secretion of parathyroid hormone, and this hormone acts to draw calcium out of the bones and into the blood. Over the long term, if kidney function deteriorates, this hormonal balance is disrupted, which can accelerate bone loss.
Furthermore, the kidney plays a crucial role in regulating the body's acid-base balance, or pH. If the body becomes chronically acidic, the body takes calcium, an alkaline mineral, from the bones to neutralize the acid. If this process is repeated, bones inevitably weaken and bone mineral density declines. Only when the kidney is healthy can the body's pH balance be well maintained, preventing bones from being unnecessarily sacrificed.
In conclusion, modern medicine clearly reveals that the kidney exerts a profound influence on bone health by activating vitamin D, regulating calcium and phosphate metabolism, and maintaining the body's acid-base balance. When the kidney weakens, it is not merely a matter of urine, but it increases the risk of osteoporosis, where bones weaken and fracture easily. To keep your bones strong, the wisdom of caring for your kidney health first is essential.
