Can Dehydration Affect Type 2 Diabetes Risk?
Although dehydration can raise your blood sugar and lead to serious health issues if you have diabetes, it is unclear whether chronic dehydration increases your risk of developing prediabetes and type 2 diabetes. In fact, people who do not have diabetes may not see the same blood sugar spikes if they are dehydrated.
“There have been a variety of things dehydration has been suggested to contribute to, but not diabetes,” Rizza says.
How much water you drink certainly doesn’t affect your risk of developing type 2 diabetes as much as other risk factors, such as your age, body weight, physical activity, diet, and overall health.
But higher levels of copeptin, a blood marker that reflects levels of the hormone vasopressin, which rises when you’re dehydrated, are linked to lower fluid intake and a greater risk of type 2 diabetes.
If you have type 2 diabetes, drinking water before meals can reduce your fasting blood sugar, body weight, and copeptin levels, in addition to reducing your dehydration risk.
