What should you do if someone is experiencing hyperglycemia?

In the case of hyperglycemia, which is characterized by elevated blood glucose levels, it is crucial to manage the condition effectively to prevent complications. Administering insulin is often necessary because insulin helps to lower blood sugar levels by facilitating the entry of glucose into the cells, where it can be utilized for energy or stored, thereby reducing glucose concentration in the bloodstream.

While drinking water can help people stay hydrated, and exercise is generally beneficial for managing blood sugar levels over time, these approaches are not immediate solutions for an acute hyperglycemic episode. Orange juice is typically used to treat hypoglycemia, not hyperglycemia, as it contains sugar that would further increase blood glucose levels. Therefore, in the context of immediate actions to take for someone experiencing hyperglycemia, administering insulin is the most appropriate and effective response.
