Blood sugar levels need to be checked more frequently when a patient is sick because illness can significantly impact insulin sensitivity and glucose metabolism. When a patient is unwell, physiological stress occurs, leading to the release of stress hormones like cortisol and adrenaline. These hormones can raise blood sugar levels by promoting glucose production in the liver while reducing the effectiveness of insulin.

Monitoring blood sugar more closely during illness ensures that any significant fluctuations can be detected and treated promptly, which is crucial for managing diabetes and preventing complications. It allows for timely adjustments to insulin doses or dietary needs based on changing glucose levels. In contrast, while other activities like sleeping, eating, or exercising do influence blood sugar levels, they do not typically create the same urgent need for increased monitoring as when a patient is ill.
