Nearly 5 million people in the UK are living with diabetes. It’s a serious condition — but with the right approach to monitoring, medication and lifestyle, it can be managed effectively, allowing you to live a full and active life.

Types of Diabetes

Type 1 diabetes is an autoimmune condition in which the immune system destroys the insulin-producing beta cells of the pancreas. It requires lifelong insulin therapy. It can develop at any age, though it typically appears in childhood or early adulthood.

Type 2 diabetes is characterised by insulin resistance — the body’s cells become less responsive to insulin — combined with progressive decline in insulin production. It accounts for around 90% of UK diabetes cases and is strongly linked to obesity, physical inactivity and diet. Lifestyle intervention can prevent or delay its onset and, in some cases, achieve remission.

Gestational diabetes develops during pregnancy and usually resolves after birth, but increases the risk of Type 2 diabetes later in life. Pre-diabetes refers to blood glucose that is elevated but not yet at diabetic levels — a critical window for lifestyle intervention.

Blood Glucose Monitoring: The Foundation of Diabetes Management

HbA1c (glycated haemoglobin) measures average blood glucose over the previous 2–3 months and is the standard clinical measure of diabetes control. Target is usually below 48mmol/mol (6.5%) for most people with Type 2. Self-monitoring of blood glucose (SMBG) via finger-prick testing or continuous glucose monitoring (CGM) provides real-time data that HbA1c cannot — it shows the daily patterns, peaks and troughs that determine quality of life and drive dosing decisions.

CGM — Changing Diabetes Management

Continuous glucose monitors such as the Freestyle Libre and Dexcom have transformed how people with diabetes manage their condition. Instead of a handful of finger-prick readings per day, CGM provides a continuous picture of glucose — showing how food, exercise, stress and sleep all affect levels. See our detailed guide: Freestyle Libre vs Dexcom.

Diet and Lifestyle in Diabetes Management

Diet is the most powerful non-pharmacological tool for managing blood glucose. Low-GI eating, carbohydrate counting, reducing refined sugars and increasing fibre all significantly improve glucose control. Exercise improves insulin sensitivity and can produce dramatic reductions in blood glucose. Even a 30-minute walk after meals meaningfully lowers post-meal glucose spikes. See: Diet and Blood Sugar.

Preventing Diabetes Complications

Poorly controlled diabetes damages blood vessels and nerves throughout the body, leading to: neuropathy (nerve damage — tingling, numbness, pain, foot ulcers), retinopathy (eye disease — leading cause of blindness in working-age UK adults), nephropathy (kidney disease), cardiovascular disease (2–4× higher risk in people with diabetes). Annual NHS checks including eye screening, foot checks, kidney function and blood pressure monitoring exist specifically to catch these early.
