women affected by PCOS often present women affected by PCOS often present abnormalities of glucose metabolism and abnormalities of glucose metabolism and lipid profile . lipid profile .

Another FactorAnother Factor

Besides insulin-resistance, it has been Besides insulin-resistance, it has been demonstrated that some of these women demonstrated that some of these women also have alterations in beta-cell-function. also have alterations in beta-cell-function. Both disorders (insulin-resistance and Both disorders (insulin-resistance and beta-cell-dysfunction) are recognized as beta-cell-dysfunction) are recognized as major risk factors for the development of major risk factors for the development of type 2 diabetes. type 2 diabetes.

clear evidenceclear evidence

women with PCOS are at increased (3–7 women with PCOS are at increased (3–7 times) risk of developing type 2 diabetes times) risk of developing type 2 diabetes (Legro(Legro et al et al., 1999 ; Wild., 1999 ; Wild et al et al., 2000 ) ., 2000 )

at increased risk for endometrial cancer at increased risk for endometrial cancer through chronic anovulation with through chronic anovulation with unopposed estrogen exposure of the unopposed estrogen exposure of the endometrium. However, epidemiological endometrium. However, epidemiological evidence to support this hypothesis is evidence to support this hypothesis is limited (Hardimanlimited (Hardiman et al et al., 2003 ). ., 2003 ).

ConclusionConclusion

insulin sensitizers, and modifying life style insulin sensitizers, and modifying life style are the key for managementare the key for management

Long-term prospective trials are needed Long-term prospective trials are needed to better delineate the nature and to better delineate the nature and magnitude of disease risks associated with magnitude of disease risks associated with PCOS PCOS
