Eligibility Criteria

Inclusion Criteria

•1\)Female subjects aged ≥ 18 and ≤ 45 years;
•2\)Caucasian race;
•3\)History of prior GDM (in the screening) during pregnancy, defined according to Carpenter and Coustan (7\) criteria, i.e. a FPG value ≥ 126 mg/dl or 2 or more of the following conditions after a 100\-g oral glucose load in the oral glucose tolerance test (OGTT): 0' ≥ 95 mg/dl, 1h PG ≥ 180 mg/dl, 2h PG ≥ 155 mg/dl, 3h PG ≥ 140 mg/dl (2\); or 2 or more of the following conditions after a 75\-g OGTT: 0' ≥ 95 mg/dl, 1h PG ≥ 180 mg/dl, 2h PG ≥ 155 mg/dl ; or 1h PG ≥ 198 mg/dl after a screening test with (8\) 50\-g oral glucose load.
•4\)Altered Glucose Regulation (IFG or IGT) confirmed at the first post\-partum follow\-up after a 75\-g oral glucose load in the OGTT, performed at entry in the time\-window of 10 to 48 months after delivery, defined as a FPG value ≥ 100 mg/dl and \< 126 mg/dl (IFG) according with latest classification (9\) and/or or a PG value ≥ 140 mg/dl and \< 200 mg/dl 2 hours after the glucose load.
•5\)Female of childbearing potential must use effective contraceptive measures for at least 1 month prior to the entry into the study and should continue to use the same contraceptive method during the overall study period. A pregnancy test at study entry is to be performed in childbearing potential women.
•6\)Written informed consent obtained.
•Are the trial subjects under 18? no
•Number of subjects for this age range: 0
•F.1\.2 Adults (18\-64 years) yes
•F.1\.2\.1 Number of subjects for this age range

Exclusion Criteria

•1\)Patients diagnosed with type 1 insulin dependent diabetes mellitus (i.e. positivity for anti\-GAD and for anti\-IA2\); in the event that results are not available at the end of run\-in, patients with positivity to antibodies will be withdrawn from the study within the first post\-baseline visit. In the case of availability of results obtained in the previous 48 months, they will be considered as valid confirmatory results and the test is not to be repeated at visit 1;
•2\)Diagnosis of diabetes in the 75\-g OGTT performed at entry, defined as a FPG value ≥ 126 mg/dl and/or or a PG value ≥ 200 mg/dl 2 hours after the glucose load;
•3\)Impaired renal function as shown by serum creatinine ³ 135 μmol/l in males and ³ 110 μmol/l in females;
•4\)Impaired liver function as shown by transaminase levels ³ twice above the upper normal range;
•5\)History of hypersensitivity to metformin;
•6\)Pregnant or breast\-feeding women, or women planning to become pregnant during the study;
•7\)Failure to use adequate contraception (women of current reproductive potential only);
•8\)Mental condition rendering the subject unable to understand the nature, scope, and possible consequences of the study;
•9\)Any clinically significant major organ system disease such as relevant cardiovascular, gastrointestinal, hepatic, neurological, endocrine, haematological or other major systemic diseases or infective diseases making implementation of the protocol or interpretation of the study results difficult;
•10\)Patients with underlying concomitant medications requiring a long\-term use of drugs potentially acting on glucose metabolism (e.g. corticosteroids, diuretics, beta\-adrenergic drugs or others);
