What factors can affect insulin absorption?

The factors that can affect insulin absorption are critical in managing diabetes effectively. Focusing on the correct answer, the injection site and temperature play a significant role in how quickly and efficiently insulin is absorbed into the bloodstream.

When insulin is injected into different areas of the body, such as the abdomen, thigh, or arm, the absorption rate can vary. The abdomen generally provides a quicker absorption compared to the thigh. Additionally, the temperature of the injection site also influences absorption. Warmer temperatures tend to increase blood flow to the area, thus speeding up the absorption process. Cold temperatures can have the opposite effect, slowing down absorption rate.

Considering the other factors: while the type of insulin used is important for determining its onset, peak, and duration of action, it does not directly influence how absorption occurs at the injection site. Similarly, the time of day that insulin is injected can impact insulin effectiveness and action depending on the individual’s body rhythms and activities but does not affect the physical absorption process itself. Age might impact insulin sensitivity or other metabolic factors, but in this context, it does not directly influence the absorption mechanism of insulin at the injection site.
