Drinking water will not reduce blood sugar quickly, but water and other sugar-free drinks can help your kidneys excrete excess sugar through urine and help bring blood sugar back to a safe level.
Drinks that help the body stay hydrated and help reduce blood sugar gradually include: Water and flavored water but no calories; unsweetened tea (hot or ice); carbonated, unsweetened soft drinks; black coffee.
A stay hydrated can help prevent hyperglycemia. Most people need about 46 glasses of water a day. If you exercise regularly or sweat a lot, you may need to drink more than the above amount. Conversely, if you are taking medication that causes water retention in the body, you may need to drink less water.
Consult your doctor about your daily water needs and the amount of water you need to supplement when your blood sugar is high.
