For many people living with diabetes, technology is an integral part of managing the condition. It helps reduce human errors, save stress, and even reduce treatment costs in some cases.

Today, people have more tools to manage their illness than ever. This article will go into the different types of diabetes technology available in the UK to help you understand which device may suit you.

Diabetes Technology in the UK (An Overview)

Almost 5 million people in the UK have diabetes or are at risk of developing the condition. Diabetes tech aims to help people diagnosed effectively manage their condition and improve their quality of life. These devices can do anything from controlling blood sugar levels to monitoring blood pressure and even delivering insulin whenever needed.

Some diabetes technology can even help in the early diagnosis of people with complications. For instance, diabetic foot disease (DFD) is a health condition that affects approximately 20% of people with diabetes.

Data-driven analytical tools can help review and interpret medical records, including unstructured data from different clinics, and identify patients at risk of developing DFD. After analysis, people can get an immediate referral to a vascular surgeon to reduce the amputation risks.

Types of Diabetes Technology in the UK

Depending on your type of diabetes, you may be familiar with techs like blood glucose monitors and insulin pens. Tech for diabetes falls into different categories, and what you choose depends on your medical history.

For Taking Insulin

The pancreas supplies insulin to keep blood sugar controlled and prevent diabetes complications. However, people with diabetes have some degree of insulin resistance, making it important to get the hormone artificially.

Using tech for insulin will help ensure you always have enough of the hormone to function. Some tech also helps you monitor blood sugar levels while administering insulin therapy.

Types of Tech for Taking Insulin

  • Smart insulin pen: A smart insulin pen is a popular device that can pair with a smartphone app. It helps calculate and track doses to remind people with diabetes of their insulin levels. Most smart insulin pens come as add-ons to your current insulin pen, or they could be reusable and filled with cartridges instead of vials.
  • Insulin pump: Small electronic devices that release insulin into the body through a catheter. Most are battery-powered and can pump insulin into the body during the day and night. They can also infuse insulin into the blood rapidly before meals when needed.

  • Available in color-coded forms, making it easy to identify the type of insulin you're using.
  • Some smart insulin pens come with memory functions that help record the time and dose of each shot.

If you're considering an insulin pump, here's why you can go for one:

  • Constant supply of insulin without injection.
  • Ability to set different basal rates at different times of the day.

Cons of Smart Insulin Pen and Insulin Pump

Here are some downsides to choosing an insulin pen:

  • Most insulin pens are expensive.
  • Insulin pens require you to inject yourself regularly to administer the hormone.

Here are some disadvantages of choosing an insulin pump:

  • Pumps can be expensive to purchase.
  • There are risks of developing a skin infection due to the catheter implanted under the skin.

How to Choose The Right Tech for Insulin Delivery (Smart Insulin Pen and Insulin Pump)

Before you get a smart insulin pen, here's what to look out for:

  • Pen needles that can fit into most brands of insulin pen.
  • Length of the needle, as shorter needles work for all body types.
  • Higher gauge of needle thickness — a higher gauge means you're using a thinner needle, which is typically less painful.

Before getting an insulin pump, here are some considerations:

  • Choose a pump suitable for your lifestyle, such as one with a handheld remote for extra convenience.
  • Consider the size of the reservoir. Most hold between 176 and 315 units, but lower-unit pumps are more suitable for kids.
  • Go for a pump that can deliver small amounts, especially for kids.
  • Integration with blood glucose meters or other types of diabetes technology.
  • Opt for a pump with software that runs on your phone, as it's more mobile.

For Blood Glucose Monitoring
