Beta-cell dysfunction and abnormal glucose metabolism among non-diabetic women with recurrent miscarriages.

Background: Subclinical beta-cell (β-cell) dysfunction is an endocrine abnormality and its association with recurrent miscarriages (RM) has not been extensively studied.

Objective: This study aimed to determine the prevalence of β-cell dysfunction and abnormal glucose metabolism [fasting blood glucose (FBG) ≥ 5.1 mmol/L] among non-diabetic women with recurrent miscarriages and to establish if there was an association between RM and β-cell dysfunction and FBG ≥ 5.
