High blood sugar can lead to energy fluctuations, causing feelings of fatigue and lethargy. Elevated glucose levels may lead to insulin resistance, impacting the body’s ability to utilize sugar for energy effectively. As a result, individuals may experience bursts of energy followed by sudden crashes, negatively affecting overall productivity and mood. Additionally, managing blood sugar is crucial for long-term health, as persistent high levels can contribute to conditions such as diabetes, cardiovascular diseases, and other metabolic disorders over time.
