Type 1 diabetes cannot yet be cured, but it is manageable. Health experts worldwide continue to explore new treatments and technologies to improve the lives of people living with this condition.
This article takes a closer look at type 1 diabetes and highlights the latest advancements in treatment and technology.
What is Type 1 Diabetes?
Type 1 diabetes is a long-term condition where the body’s immune system attacks insulin-producing cells in the pancreas. This results in little or no insulin production. Insulin is essential because it helps the body turn glucose (sugar) into energy. Without enough insulin, blood sugar levels can rise to dangerous levels.
While most people are diagnosed with type 1 diabetes in childhood, it can develop at any age, usually before 40. The exact cause is unknown, but having a close family member with the condition increases your risk. However, experts stress that there is currently no way to prevent type 1 diabetes.
The NHS lists common signs of type 1 diabetes as feeling very tired, having frequent infections like thrush, being extremely thirsty, and needing to urinate more often, especially at night.
Insulin treatment is the cornerstone of managing type 1 diabetes. It can be given through injections or an insulin pump. Regularly monitoring blood sugar levels is vital to avoid serious health problems.
Potential Complications of Type 1 Diabetes
If not properly managed, high blood sugar can damage blood vessels. Damaged blood vessels affect blood flow and nerve function. This can lead to numbness or loss of feeling in parts of the body.
Complications from type 1 diabetes fall into two groups: chronic (long-term) and acute (short-term).
Chronic Complications
- Eye problems (retinopathy): Some people develop diabetic retinopathy, which can cause vision loss. Early detection can prevent serious damage.
- Foot issues: Nerve damage reduces feeling in the feet, and poor circulation slows healing. Untreated, these problems may lead to serious infections or amputation.
- Stroke and heart attack: Prolonged high blood sugar damages blood vessels, increasing the risk of heart attacks and strokes.
- Kidney problems (nephropathy): High blood sugar and blood pressure can harm kidneys, reducing their ability to remove waste.
Acute Complications
- Hypos: Low blood sugar levels.
- Hypers: High blood sugar levels.
- Diabetic ketoacidosis (DKA): A dangerous emergency where a lack of insulin causes toxic chemicals called ketones to build up.
Once damage occurs in one part of the body, other areas may be at risk too. Preventing or delaying complications is crucial.

How to Reduce the Risk of Complications
Complications are not unavoidable. A major 20-year study supported by Diabetes UK showed that keeping blood sugar and blood pressure within target ranges greatly reduces risks, including kidney disease, heart attacks, and early death.
Managing your diabetes well means attending regular health checks, working closely with healthcare providers, choosing healthy foods, staying active, quitting smoking, and regularly checking your blood sugar.

Latest Advances in Diabetes Technology
Diabetes technology includes devices and software that help people manage their condition better. These tools can significantly improve quality of life, though not every device suits everyone.
There are three main categories of diabetes technology:
- Insulin delivery: Most use insulin pens, but insulin pumps and smart pens are also common. A new system called the “closed-loop” or artificial pancreas adjusts insulin automatically based on blood sugar readings.
- Blood sugar monitoring: Traditional monitors require finger pricks. New devices like continuous glucose monitors (CGMs) and flash monitors allow easier, pain-free tracking.
- Other tools: Ketone monitors check for dangerous ketone levels. Various apps help with diet, exercise, and tracking carbohydrate intake.
Some technology is available on the NHS; eligibility details are on Diabetes UK’s website. Private purchase is possible but can be costly. Always consult healthcare professionals before buying.
Ongoing Research into Treatments
There is no cure yet for type 1 diabetes, but UK scientists are exploring several promising areas:
- Stopping the immune attack: Immunotherapies aim to prevent the immune system from destroying insulin-producing beta cells. Early trials show these may delay diabetes onset or protect remaining cells after diagnosis.
- Beta cell replacement: Replacing destroyed beta cells is key. Donor transplants exist but are limited and temporary. Scientists are developing lab-grown beta cells, which have shown success in animal studies.
- Protecting new beta cells: Researchers are testing ways to shield transplanted beta cells, such as encapsulation or combined immunotherapies, to ensure long-term survival.
The Type 1 Diabetes Grand Challenge, a partnership between Diabetes UK, the Steve Morgan Foundation, and JDRF, accelerates research into new treatments and a cure.
Final Thoughts
Living with type 1 diabetes can be challenging. However, with proper care, people can manage their condition and lead full lives. While a cure is not yet available, current research offers hope for the future.
