Non-Alcoholic Fatty Liver Disease. Non-alcoholic fatty liver disease (NAFLD) occurs when extra fat builds up in the liver. NAFLD has become the most common liver disease in Canada (estimated 30%), with an increased risk for persons with obesity, insulin resistance, diabetes and hypertension. NAFLD has serious implications for liver, heart, brain and kidney health. The University of Manitoba is conducting a study to determine how common NAFLD is and this condition’s long-term outcomes. At NAFLD clinics, ultrasound is used to detect fat in the liver. If there is fat, another ultrasound determines liver damage. For more information call C.W. Wiebe Centre 204-325-4312.
