The prevalence of diabetes mellitus increases with age, and the number of older persons with diabetes is expected to grow with an aging population. The incidence of diabetes also rises with obesity, more sedentary lifestyles and increased urbanization. Understanding diabetes is the first step to managing it.
DIABETES MELLITUS RESOURCE CENTRE
Diabetes mellitus is a condition which is characterized by high blood sugar levels, resulting from shortage of insulin production (Type I), or defects in insulin action on its target organs (Type II). Blood sugar levels in the body are tightly regulated by the hormone called insulin. Insulin is produced by the pancreas, and under healthy conditions, it keeps glucose levels within normal levels. In Singapore, about 1 in 12 adults is diabetic, of which 85-90% are of the Type II variety.
Eating increases glucose levels. This stimulates the pancreas to produce insulin which acts to reduce glucose levels back to normal. In patients with diabetes, the insufficient production of insulin, or the resistance of the body's cells to the action of insulin (insulin resistance) will cause glucose levels to remain elevated.
