What are the symptoms of diabetes?

People who think they might have diabetes must visit a physician for diagnosis. They might have SOME or NONE of the following symptoms:

• Frequent urination

• Excessive thirst

• Unexplained weight loss

• Extreme hunger

• 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.
