What is critical for maintaining blood sugar levels post-insulin administration?

Proper meal timing is crucial for maintaining blood sugar levels following insulin administration because insulin facilitates the uptake of glucose into cells. After insulin is injected, the body requires a supply of glucose to avoid hypoglycemia, which can occur if there is no food intake to match the insulin action. Eating balanced meals at appropriate times helps to ensure that glucose is available in the bloodstream as insulin lowers blood sugar levels. This timing helps establish a reliable balance between insulin activity and glucose levels, preventing complications associated with both high and low blood sugar.

In contrast, while regular exercise can improve overall insulin sensitivity and hydration is important for general health, they do not directly address the immediate need for glucose following insulin administration. Frequent monitoring of blood sugar levels is vital but is primarily a tool for observation and does not directly influence the blood sugar levels in the way that consuming food does.
