Insulin Pumps: A Transformative Option for Diabetes Management

Young British science writer Jasmin Notarangelo conducted a deeply personal inquiry into a critical global health concern that directly impacts her family, as detailed in her award-winning essay. Her essay, which focuses on the management of Type 1 diabetes, secured the 2024 Young Science Writer of the Year award. The following text presents an adapted version of that essay. Jasmin Notarangelo, a teenager, shares that both her mother and grandmother live with Type 1 diabetes. This condition is an autoimmune disease, meaning the body’s immune system targets and damages pancreatic cells, rendering them unable to produce insulin. Insulin is the hormone essential for maintaining blood sugar levels within a healthy range, and Type 1 diabetes is manageable but not curable. For individuals without diabetes, insulin is naturally released upon eating, which prevents blood sugar levels from rising excessively. This natural process is absent in diabetics. Untreated, their blood sugar can reach dangerously high levels. Management strategies include glucose monitoring, adherence to healthy dietary choices, regular exercise, and crucially, insulin injections. Insulin injections can be a source of pain, potentially leading to bruising and the accumulation of scar tissue, fat, and protein, a condition known as lipohypertrophy. Jasmin Notarangelo observes that these injections can be distressing and limit daily activities. Individuals with diabetes must carry their insulin, and those with impaired eyesight or mobility may find the injection process challenging. This perspective leads to the belief that a superior and more efficient method for insulin delivery exists. The insulin pump, a compact device approximately the size of a deck of cards, delivers a continuous supply of longer-acting insulin via a cannula inserted beneath the skin. This device is available in two configurations: tubed and tubeless. Tubed pumps have a lifespan of several years, with the insulin reservoir requiring replacement every two to three days. Tubeless pumps are single-use devices, with a new pump applied every two to three days. Frequent changes are necessary to ensure a continuous insulin supply and to mitigate the risk of infection. A key benefit of the insulin pump is the enhanced flexibility it offers individuals with irregular schedules or those needing smaller insulin doses. This enables people with varying work shifts, who may not eat or exercise at consistent times daily, to still receive precise insulin dosages. According to a 2011 report by the Australian Institute of Health and Welfare, 86% of surveyed individuals indicated that the insulin pump integrated into their lifestyle more effectively than injections. Furthermore, replacing an insulin supply or pump every two or three days is considered more convenient than administering injections, which typically occur four times daily. Nevertheless, insulin pumps present certain drawbacks and are not suitable for all individuals. Patients with visual or mobility impairments might find changing their pump challenging, a difficulty also associated with insulin injections. Additionally, cannulas can bend, impeding insulin flow, and the pump may inadvertently detach from its tubing without the user’s awareness. The NHS provides insulin pumps exclusively to patients who frequently experience unannounced episodes of dangerously low or high blood sugar, referred to as “hypos” or “hypers.” Consequently, numerous individuals opt to self-fund an insulin pump, which generally costs between £2,000 and £3,000. The annual cost for necessary equipment adds just over £1,000, making it unaffordable for many diabetics. Dr. Iain MacLeod, a General Practitioner at Prestonpans Group Practice in Scotland, informed Jasmin Notarangelo that insulin pumps have been “life-changing for many patients.” He stated, “I think [they] have been an excellent addition to the range of options available for managing diabetes.” Dr. MacLeod further noted that pumps “allow more flexibility,” but acknowledged that they “are a lot more expensive than standard insulin therapy so, in these times of huge financial pressures within the NHS, it is probably not realistic for all diabetic patients to get the more expensive treatment options.” He concluded, “If the pump is the best option for a patient, then I would gladly recommend it.” Insulin pumps are gaining greater accessibility and even becoming more fashionable, with companies offering accessories and protective pouches. This trend, Jasmin Notarangelo believes, facilitates living with and accepting the device, which frequently proves life-changing. Jasmin Notarangelo asserts the importance of diabetics having access to all necessary treatment options, enabling them not only to manage their condition but also to thrive. Jasmin Notarangelo attends Musselburgh Grammar School in East Lothian. The judging panel described her essay as an “outstanding piece that presented a compelling message about the accessibility of healthcare.” The runners-up in the competition were Anna Joby, recognized for her essay on light pollution, and Lissie Marsh, for her work on the unobserved environmental impacts of excessive tire use.
