Understanding Type 2 Diabetes as You Age

By the Primary Health Awareness Trust

Type 2 diabetes is one of the most common long-term conditions affecting older adults in the UK. While it often develops gradually, its impact can become more serious as we age — especially if not managed well. But the good news is: with the right knowledge, support, and small daily habits, it is absolutely possible to live a full and active life.

What Is Type 2 Diabetes?

Type 2 diabetes is a condition where the body becomes resistant to insulin (the hormone that helps control blood sugar), or doesn’t produce enough of it. This leads to higher levels of glucose in the blood over time.

Unlike Type 1 diabetes, which often starts in childhood, Type 2 usually develops later in life — and is especially common in adults over 60. It’s linked to factors like body weight, physical activity, family history, and age-related metabolic changes.

Why Is Age a Risk Factor?

As we get older, several natural changes in the body can increase our risk of developing Type 2 diabetes:

• We may carry more weight around the middle, which affects how insulin works.
• Muscle mass decreases, affecting how our body processes sugar.
• We may become less physically active, especially after retirement or illness.
• Some medications (like steroids or statins) can increase blood sugar levels.

These changes don’t mean diabetes is inevitable — but they do mean we need to stay alert and proactive.

Early Signs to Look Out For

Some symptoms of Type 2 diabetes may seem minor at first, especially in older adults. Common signs include:

• Feeling more tired than usual
• Going to the toilet more often, especially at night
• Feeling very thirsty or having a dry mouth
• Unexplained weight loss or muscle loss
• Slow-healing wounds
• Blurry vision

If you notice any of these signs, speak to your GP or practice nurse. A simple blood test can help detect diabetes early — when it’s most manageable.

How Is Type 2 Diabetes Diagnosed?

The most common test used in the UK is called the HbA1c test. It gives an average blood sugar level over the past 2–3 months. If your level is above 48 mmol/mol, you may be diagnosed with diabetes.

Sometimes you may be told you have “pre-diabetes” or a “high risk” score — this is a vital window to make lifestyle changes and prevent it from progressing.

What Can You Do Right Now?

If you’re over 60 and haven’t had a diabetes check recently, ask your GP surgery for a health review — especially if you’ve had recent weight changes, fatigue, or other symptoms.

Even gentle actions like walking more after meals, swapping refined carbs for wholegrains, and staying hydrated can make a real difference in blood sugar levels over time.

Final Thought

Diabetes is common, but it doesn’t have to control your life. Understanding the condition is the first step. With support, education, and small, consistent actions, you can manage your health with confidence and enjoy the things that matter most — from family meals to community walks to peace of mind.
