Diabetes mellitus is a metabolic disorder characterised by high blood sugar (glucose) levels. The condition results from the body’s inadequate production of insulin or the body’s altered response to insulin, or both. Diabetes causes abnormally high glucose levels (hyperglycemia), circulatory problems, and nerve damage. Diabetes is a chronic condition affecting people of all ages and walks of life. The disease can cause a number of long-term complications, resulting in disability, reduced quality of life, and premature death. Exercise plays an important role in diabetes. Physiotherapists are experts in exercise prescription for people with chronic illnesses and are therefore able to provide advice on physical activity and promote self-management practices. Physiotherapists also assist with the management of complications associated with diabetes.
