A recent study has revealed that obesity may play a role in reproductive problems in women with type 1 diabetes. "Women with type 1 diabetes remain at risk of significant reproductive problems despite improvements in current therapies, and this may be partly explained by the high prevalence of obesity in this group," said lead researcher Eleanor Thong, M.B.B.S., Monash Centre for Health Research and Implementation, Clayton, Australia. The researchers found 24 per cent of women with type 1 diabetes were obese, compared with 16 percent of those without diabetes. Another notable finding was that one in four women with type 1 diabetes was current smoker, compared to one in six controls. Menstrual irregularities were seen in 47 per cent of those with type 1 diabetes, compared with 35 per cent of those without the disease. Polycystic ovary syndrome (PCOS) was found in 14 per cent of those with diabetes, compared with 5 per cent in those without the disease.
