Chronic kidney disease is when your kidney is not functioning properly. Kidneys contain filters called nephrons. It is the their job to filter the blood of waste products and extra fluid. As a result, your body flushes the waste out as urine. The most common causes of chronic kidney disease are diabetes and high blood pressure. If your blood vessels contain a high concentration of sugar and cholesterol, the nephrons would take the exhaustive work. In the long run, if you keep eating unhealthy food, the kidney could no longer catch up. Thus, resulting to chronic kidney disease.
If you were to go in the career cluster of healthcare (medical), you would be able to assist your patients' needs better, understand what is really going on in their bodies, and give them suggestions for improving their overall health. Hope this helps. :D. Let me know if you have any questions about my explanations and feel free to ask more questions.
