Type 2 diabetes is the most common type of diabetes, affecting 85-90% of all people with this disease. Diabetes occurs where the pancreatic cells have increased resistance or reduced ability to respond to insulin and absorb glucose (sugar) from the blood into the muscle and fat cells to use for energy. While it usually affects older adults, it is becoming more common in younger adults and teenagers.
Type 2 diabetes normally occurs together with increased blood pressure, high blood cholesterol and increase body weight. The condition can be managed by a controlled diet and increased exercise, however most people will require oral medication and some will eventually need to go on insulin therapy as their pancreas “wears out”.

Diabetes can lead to increased risk of infection, sensation loss and reduced circulation, especially in the feet. The combination of numb, insensitive feet (neuropathy) and poor circulation means cuts or injuries may go unnoticed and progress to infected ulcers which may heal poorly.
