The one major feature uniting Types 1 and 2 diabetes is high blood sugar levels resulting from your body producing too little insulin. Increasing your water intake helps to treat and prevent these spikes in blood glucose levels in a variety of ways. The beneficial effects of water on blood glucose levels extend to people without diabetes, as a study published in 2011 in "Diabetes Care" indicates that drinking adequate amounts of water decreases your risk of developing Type 2 diabetes.
Water Intake and Glucose Levels
When your blood glucose levels are too high, your body tries to rid itself of some of this glucose in your urine. Drinking more water can help to replenish your fluids, potentially helping your body excrete more glucose in your urine. Increasing your water intake has the added benefit of potentially decreasing the amount of glucose you get from food. According to Dr. Richard Holt and colleagues, people who drink too little water tend to consume as much as 30 percent more calories than those who drink adequate amounts of water, potentially leading to dangerous spikes in blood sugar.
