How frequently should blood glucose levels be monitored during illness?

Monitoring blood glucose levels more frequently than usual during illness is critical because physical stressors such as fever, infection, or any form of acute illness can significantly impact blood glucose levels. Illness can lead to increased glucose production from the liver and altered insulin sensitivity, which may result in hyperglycemia. Additionally, if the individual is unable to eat or drink normally, it can complicate blood glucose management.

Frequent monitoring allows for timely adjustment of insulin doses or dietary changes, ensuring that blood glucose levels remain within a target range. This proactive approach helps to prevent complications such as diabetic ketoacidosis or hyperglycemic hyperosmolar state, which can arise from untreated elevated blood glucose levels during periods of illness.

While monitoring periodically is vital under normal circumstances, the need for intensified monitoring during illness reflects the body's altered metabolic state, necessitating a more responsive management strategy.
