What are the advantages of hybrid closed loop insulin pumps?

Living with diabetes necessitates constant vigilance and meticulous management to ensure a healthy and fulfilling life. Over time, advancements in medical technology have introduced innovative solutions to simplify and enhance this management process. One notable advancement is the hybrid closed loop insulin pump, commonly known as an artificial pancreas. In this article, leading consultant diabetologist Dr Natasha Patel delves into the advantages and disadvantages of this groundbreaking device, helping you make an informed decision regarding its suitability for yourself or your loved ones.

What are the advantages of hybrid closed loop pumps?

Hybrid closed loop pumps come with several advantages, including:

• Automated insulin delivery: One of the most significant benefits of the closed loop insulin pump is its capacity for automating insulin delivery. This device employs continuous glucose monitoring (CGM) to monitor blood sugar levels in real time and adjusts insulin delivery accordingly. This minimises the need for manual interventions, reducing the risks of hyperglycaemia and hypoglycaemia.
• Precise glucose control: The closed loop system is engineered to maintain blood sugar levels within a narrow range, diminishing the fluctuations that can contribute to diabetes-related complications over time. This precise glucose control can contribute to overall better health and a reduced risk of long-term complications.
• Reduced burden and mental strain: Managing diabetes can be mentally and emotionally taxing. With a closed loop insulin pump, there is less necessity for constant insulin dosage calculations and concerns about potential blood sugar spikes or crashes. This can lead to a substantial reduction in the daily burden associated with diabetes management.
• Enhanced quality of life: The automation provided by the closed loop system offers greater flexibility in daily activities and meal planning. Individuals can enjoy increased freedom without the constant need to structure their lives around insulin dosing schedules.

What are the disadvantages of hybrid closed loop pumps?

Hybrid closed loop pumps also come with a number of disadvantages. These include:

• Learning curve: Transitioning to a closed loop system involves a learning curve. Users must acquaint themselves with the device's settings, comprehend its responses to various situations, and become proficient in interpreting glucose sensor data effectively. This initial adjustment period may necessitate time and patience.
• Technology reliability: Like any technological device, closed loop insulin pumps are not immune to technical glitches or malfunctions. Relying on a machine for insulin delivery implies that any technical issues could have serious consequences. It is crucial to have contingency plans and be knowledgeable about reverting to manual insulin delivery if necessary.
• Customisation challenges: Although closed loop systems are designed to adapt to various scenarios, they may not perfectly align with the unique needs of every individual. Fine-tuning settings and customising the system to accommodate personal insulin sensitivity can be a complex process requiring ongoing communication with healthcare professionals.
• Constant attachment: Being attached to both a glucose sensor and the pump can be disheartening for some individuals.

The closed loop insulin pump marks a significant advancement in diabetes management technology, offering the potential for precise glucose control, reduced daily burdens, and an improved quality of life. Nevertheless, it is imperative to thoroughly evaluate the pros and cons before making a decision. Consultation with doctors, diabetes educators, and individuals experienced with the technology can provide valuable insights to assist in determining whether a closed loop system is the appropriate choice. Keep in mind that diabetes management is highly individualised, and the optimal approach will depend on your unique requirements, preferences, and lifestyle.
