Episode Description

  • Kidney stones form when minerals in urine crystallize and clump together. Among all types, calcium oxalate stones are the most common
  • Calcium oxalate stones were long thought to result solely from physical and chemical processes, but a recent study found that bacteria are embedded inside them
  • These bacteria form dense biofilms within the stone, creating sticky structures that give crystals more places to attach, helping the stone form and grow
  • A separate study showed that kidneys host their own microbiome, where certain bacteria promote stone formation while others help limit crystal growth within kidney tissue
  • Simple steps like staying hydrated, moderating oxalates, reducing seed oils, moving more, and avoiding unnecessary antibiotics can help lower stone risk while supporting kidney microbial health
