The American Diabetes Association (ADA) warn that using only sliding scale insulin for treatment is ineffective for most people. Doctors developed it several decades ago as a guide to insulin dosage, but few healthcare professionals now use it. The sliding scale is one way of working out how much insulin to take before each meal.

A doctor will help a person with diabetes to create this chart based on factors such as how the person’s body responds to insulin and their daily activity. Sliding scale insulin therapy involves following a chart of insulin dosages.
