People who think they might have diabetes must visit a physician for diagnosis. They might have SOME or NONE of the following symptoms:
Unexplained weight loss
Sudden vision changes
Tingling or numbness in hands or feet
Feeling very tired much of the time
Very dry skin
Sores that are slow to heal
More infections than usual
Nausea, vomiting, or stomach pains may accompany some of these symptoms in the abrupt onset of insulin-dependent diabetes, now called type 1 diabetes.
A number of studies have shown that regular physical activity can significantly reduce the risk of developing type 2 diabetes. Type 2 diabetes also appears to be associated with obesity.
Researchers are making progress in identifying the exact genetics and "triggers" that predispose some individuals to develop type 1 diabetes, but prevention remains elusive.
