"Renal" refers to anything related to the kidneys, which are vital organs in the human body responsible for filtering blood, removing waste, and balancing fluids. The kidneys also help regulate blood pressure and produce hormones that are essential for red blood cell production and bone health. Conditions affecting the renal system can lead to various health issues, such as chronic kidney disease or kidney stones. Maintaining renal health is crucial, and it can be supported through proper hydration, a balanced diet, and regular medical check-ups to monitor kidney function.
