Specialist reveals the main cause of kidney stones

As we age, kidney problems become more common, and one of the most common disorders is the formation of kidney stones, also known as "stones." While their appearance is often attributed to poor hydration or an inadequate diet, there is a lesser-known and potentially more dangerous factor: the overuse of certain supplements.

Nephrologist Borja Quiroga of the Jiménez Díaz University Hospital, He warned that self-medication with vitamins, without medical supervision, can have serious consequences.

Although vitamin D plays a crucial role in bone health and immune function, consuming it in high doses can upset the body's balance. Dr. Quiroga explains that a Excessive intake of this vitamin increases calcium absorption, which can lead to the mineral accumulating in the kidneys, forming stones.

The risk is heightened because these stones can develop without causing symptoms for weeks or even months. Many people only discover the problem when they are already suffering from kidney stones or infections.

Currently, the trend of taking supplements without prior medical evaluation has become more common, driven by social media trends and unscientific recommendations. Therefore, Quiroga emphasizes that there is no universal vitamin D dose for everyone. Each case should be assessed individually by a professional.

If you're considering taking vitamin D supplements, the safest step is to have your blood and urine tested beforehand. This will help you determine your actual levels and avoid unnecessary risks. It's also advisable to adopt preventative habits, such as staying well hydrated, especially in hot climates, reducing your consumption of foods high in oxalates (such as beets, chocolate, or spinach), and limiting your salt intake. Genetics play a role, yes, but daily habits are crucial for protecting kidney health.
