In more cases than would normally be expected, people who develop type 2 diabetes have a history of carpal tunnel syndrome. The wrist nerve problem sometimes predates the onset of diabetes by up to 10 years, according to a UK study.
Results showed that, after accounting for other risk factors, the pre-diabetes group was 36 percent more likely to have had carpal tunnel syndrome in the past than the control group.

Bell's Palsy, another nerve fiber disorder, was also observed to have occurred frequently in the pre-diabetic group in the same study, but it's significance was not established statistically.
