In conclusion, both Continuous Glucose Monitoring and Fingerstick Glucose Testing have their advantages and disadvantages. The best choice for an individual with type 1 diabetes depends on their unique needs, preferences, and financial circumstances.

Insulin Therapy

Diabetes Type 1- Insulin Therapy

Rapid-Acting Insulin

Rapid-acting insulin, such as Humalog, NovoLog, or Apidra, begins working within 10 to 20 minutes and peaks within 60 to 90 minutes. This type of insulin is often used to manage blood sugar levels quickly during meals or snacks and to correct high blood sugar. It is essential to closely monitor blood sugar levels when taking rapid-acting insulin to avoid hypoglycemia (low blood sugar) and adjust dosages accordingly. An example of a rapid-acting insulin schedule could be injecting it right before meals to better handle the rise in blood sugar levels.

Long-Acting Insulin

Long-acting insulin, such as Lantus, Levemir, or Tresiba, provides a steady release of insulin over 24 hours, helping to maintain consistent blood sugar levels throughout the day. This type of insulin is typically injected once or twice per day and works to mimic the natural insulin production of a non-diabetic person. Long-acting insulin helps lower the risk of high blood sugar overnight and reduces blood sugar fluctuations throughout the day. It’s important to always administer long-acting insulin at the same time every day for the best results.

Calculating Insulin Dose

To maintain proper blood sugar levels, it is crucial to calculate the correct insulin dose for each individual. Factors affecting insulin dose include weight, activity levels, carbohydrate consumption, and even factors like stress or illness. There are two primary methods to calculate insulin dosages: the fixed-dose method and the carbohydrate counting method.

  • Fixed-dose method: This involves taking a predetermined amount of insulin at certain times of the day, without adjusting for variation in carbohydrate consumption. This method may be suitable for older or less active individuals but offers less flexibility.
  • Carbohydrate counting method: This method involves calculating the amount of insulin needed based on the number of carbohydrates consumed, typically done by using an insulin-to-carb ratio. Sensitivity to insulin varies among individuals, so working with a healthcare provider is essential to determine the appropriate insulin-to-carb ratio. This method is more flexible and allows for better control over blood sugar levels.

In conclusion, for optimal type 1 diabetes management, it is crucial to understand the different types of insulin, how they affect blood sugar, and how to calculate the proper insulin dosages. Adopting an appropriate insulin therapy regimen can greatly improve the quality of life for individuals with type 1 diabetes.
