“What is the emergency treatment for low blood sugar?”

Simple sugar-based items are usually rapidly absorbed and should raise blood glucose levels within 5-15 minutes. These could include fruit juice - orange, apple, pineapple, cranberry. Honey is another option. Also candies like gummys are concentrated sugar and will also work quickly.

I would recommend in an emergency, liquid sugar at home. Examples are Orange juice, Gingerale, Coke, and Pepsi. Liquid sugar products raise your blood sugar faster than solid sugar products. The usual time is 10 minutes.
