What is a potential consequence of injecting insulin into a muscle?

Injecting insulin into a muscle can lead to faster absorption of the medication compared to other injection sites, such as subcutaneous tissue. This rapid absorption can result in more immediate and intense physiological effects, which may contribute to fluctuations in blood glucose levels. When insulin is absorbed quickly, it may lower blood glucose too fast, creating a risk of hypoglycemia—particularly if the timing and dosage aren't carefully managed in relation to food intake or physical activity.

In contrast, absorption through subcutaneous tissue allows for a steadier release of insulin, helping to maintain more stable blood glucose levels. This detail highlights the importance of proper injection techniques and site selection to ensure effective management of diabetes and avoidance of complications related to blood sugar levels. Understanding the dynamics of insulin absorption is crucial for those administering insulin, as it informs how patients might need to adjust their dietary intake or observe their blood glucose monitoring following an injection.
