As water contains no carbohydrate or calories, it is the perfect drink for people with diabetes. Studies have also shown that drinking water could help control blood glucose levels.
The bodies of people with diabetes require more fluid when blood glucose levels are high. This can lead to the kidneys attempting to excrete excess sugar through urine.
Water will not raise blood glucose levels, which is why it is so beneficial to drink when people with diabetes have high blood sugar, as it enables more glucose to be flushed out of the blood.
Having high blood glucose levels can also increase the risk of dehydration, which is a risk for people with diabetes mellitus.
People with diabetes insipidus also have a heightened dehydration risk, but this is not linked to high blood glucose levels.
Drinking water helps to rehydrate the blood when the body tries to remove excess glucose through urine.
