Scientists say people who drink two glasses or less of water each day are more likely to develop blood sugar levels in the pre-diabetes range. That puts them at risk of developing the disease itself.
But whether simply drinking water will cut your risk of blood sugar problems is still up in the air.
Scientists say one possible explanation could be that people who drink little water may instead be reaching for sugary drinks. That could lead to weight gain and impaired blood sugar control.
The study appears in Diabetes Care.
