Water is the most essential element for our bodies, with the exception of oxygen, so when we are dehydrated in any way, all of our organ systems will suffer. Water helps with the transportation of nutrients throughout the body, including sugar, which can help with the balance release of glucose and insulin in the body. This will prevent the variability that diabetes causes, allowing diabetic patients to live a more normal life. Furthermore, water stimulates urination, which can remove excess salts and sugars from the body, further helping to balance your glucose levels.
