Drinking water helps prevent dehydration but does not directly lower blood sugar
Drinking water does not directly lower high blood sugar, according to diabetes educator and nurse Megan Asterino-McGeean.
She says staying hydrated can help prevent dehydration from making the situation worse.
When the body loses water, blood becomes more concentrated, which can raise a blood sugar reading.
High glucose can also lead the kidneys to remove more water through urine, increasing the risk of dehydration.
Water supports fluid balance, not glucose control, and drinking more than the body needs will not bring glucose back to normal.
For people with type 2 diabetes, managing glucose depends on medication, monitoring and the care plan set for each person.
The guidance is to keep hydrated while following the treatment recommended by a health care team.
Drinking water helps prevent dehydration but does not directly lower blood sugar, diabetes educator Megan Asterino-McGeean said.
Dehydration can make blood sugar more concentrated because less fluid is available in the body.
High blood sugar can also cause the kidneys to remove more water through urine.
Water supports fluid balance, while managing blood sugar depends on prescribed treatment and care.
