Type 2 diabetes once known as adult-onset or noninsulin-dependent diabetes, is a chronic condition that affects the way your body metabolizes sugar (glucose), your body’s main source of fuel. With type 2 diabetes, your body either resists the effects of insulin – a hormone that regulates the movement of sugar into your cells – or doesn’t produce enough insulin to maintain a normal glucose level. Untreated, type 2 diabetes can be life-threatening.
Type 2 diabetes symptoms may develop slowly. In fact, you can have type 2 diabetes for years and not know it. Look for: increased thirst and frequent urination; increased hunger; weight loss; fatigue; blurred vision; slow-healing sores or frequent infections; and areas of darkened skin. Although long-term complications of diabetes develop gradually, they can eventually be disabling or even life-threatening. Some of the potential complications of diabetes include: heart and blood vessel disease; nerve damage; kidney damage; eye damage; foot damage; skin and mouth conditions; osteoporosis; Alzheimer’s disease; and hearing problems.
