Diabetes is a chronic disease characterized by high blood sugar levels. It occurs when the body cannot produce or properly use insulin, the hormone needed to convert food into usable energy. More than 23 million Americans have been diagnosed with diabetes, with another 5.7 million affected people still undiagnosed.
Types
Type 1 diabetes occurs when the pancreas produces little or no insulin. Type 2 diabetes occurs as the body loses its ability to use insulin and gradually becomes insulin-deficient.
Diagnosis
Both forms can strike at any age, but Type 1 is most often diagnosed in childhood or early adulthood, and Type 2 occurs more frequently in adults.
Prevalence
Type 2 diabetes is the most common form, accounting for up to 95 percent of adult cases. Type 1 makes up 5 percent to 10 percent of adult diabetes cases.
Symptoms
Symptoms of Type 1 diabetes include fatigue, increased thirst and urination, nausea, vomiting and weight loss. People with Type 2 might experience blurred vision, fatigue, increased hunger and thirst, and more frequent urination.
Treatment
Type 1 diabetes requires daily insulin injections, while Type 2 is usually managed with exercise and diet changes. Both forms of diabetes are incurable.
