Which of the following is NOT a complication of high glucose levels?

Enhanced digestion is not a complication of high glucose levels. In fact, high glucose levels, often associated with conditions like diabetes, typically lead to several serious health complications rather than improved bodily functions such as digestion. Chronic elevated blood sugar can contribute to cardiovascular issues such as heart attacks and strokes, as high glucose can damage blood vessels and increase the risk of atherosclerosis. Additionally, nerve damage, known as diabetic neuropathy, is a common complication due to sustained high glucose levels, which can harm nerve endings over time. Therefore, the other options represent significant health risks tied to high glucose levels, while enhanced digestion does not fit into this category.
