The sliding scale for insulin-dependent diabetics bases the amount of insulin taken on blood sugar levels before a meal, explains Healthline. This type of treatment is most often used in hospitals or other health care facilities, where it is easy for health care providers to monitor blood sugar levels.
Other types of insulin treatment include fixed-dose insulin and carbohydrate-to-insulin ratios, states Healthline. Fixed-dose insulin treatment is when a patient takes a prescribed amount of insulin at each meal, and insulin-to-carbohydrate ratio treatment involves taking a certain amount of insulin for the amount of carbohydrates eaten. The insulin-to-carbohydrate method is considered a better treatment choice than the sliding scale treatment option.
