What might happen if insulin is injected into an area that is not adequately fatty?

Injecting insulin into an area that is not adequately fatty can hinder insulin absorption. Insulin should ideally be injected into subcutaneous fat, as this layer provides the most consistent and reliable absorption of the hormone into the bloodstream. When insulin is injected into a non-fatty area, such as muscle tissue, it may be absorbed more unpredictably and quickly, leading to fluctuations in blood glucose levels. This can result in erratic control of diabetes.

Areas without sufficient fatty tissue may not allow the insulin to disperse evenly, leading to localized absorption that could cause peaks and troughs in glucose levels. In contrast, injecting into an appropriate fatty area allows for a more gradual release of insulin, resulting in better management of blood sugar levels throughout the day. Understanding the significance of injection sites can help individuals with diabetes maintain optimal control over their blood glucose levels.
