This course helps patients and family carers understand how the heart, kidneys, liver, and metabolism work together as one system. Health problems rarely happen in isolation. Changes in blood sugar, blood pressure, weight, or kidney function affect the whole body. You will learn why conditions like diabetes, kidney disease, fatty liver disease, and heart disease often occur together. The course explains key tests, warning signs, and treatment options in clear, plain language. Experts walk you through practical steps to lower risk, support daily health, and spot problems early. The focus stays on action. You learn how to track important numbers, ask the right questions at appointments, and build a care plan that fits real life. The goal is confidence. You leave knowing how to support long term health for yourself or someone you care for.
