Prediabetes: Early Signs and How to Prevent It

Prediabetes is a condition affecting millions across the globe without them even knowing it. It acts as a red flag, warning you that your blood sugar levels are higher than normal—but not high enough to qualify as diabetes.

What is Prediabetes?

Prediabetes is essentially a wake-up call. It indicates that your body isn’t processing blood sugar (glucose) effectively, but it hasn’t yet reached the stage where the condition is classified as type 2 diabetes.

Left unaddressed, prediabetes can progress to type 2 diabetes, which comes with a higher risk of complications like heart disease, stroke, kidney issues, and vision problems. But with the right changes to your lifestyle, you can prevent or delay this progression.

Early Signs of Prediabetes

The tricky thing about prediabetes is that it doesn’t usually come with obvious symptoms. Most people are diagnosed only through routine blood tests. However, there are a few signs that may point to an underlying issue with blood sugar regulation.

1. Increased Thirst and Frequent Urination

If you find yourself feeling thirsty more often and needing to urinate frequently, it could indicate higher blood sugar levels. These symptoms occur when excess glucose in your blood pulls water from your tissues, leading to dehydration.

2. Fatigue

Feeling constantly tired or lacking energy may be linked to problems with how your body processes sugar. Insulin resistance can prevent your cells from getting the energy they need, leaving you drained.

3. Darkened Patches of Skin (Acanthosis Nigricans)

Some individuals with prediabetes develop dark, velvety patches of skin in areas like the neck, armpits, or groin. These patches can be an early sign of insulin resistance.

4. Slow Healing Wounds

Cuts and bruises that take longer than usual to heal can be a sign of elevated blood sugar levels. High glucose can impair your body’s ability to repair itself efficiently.

5. Sudden Weight Gain, Especially Around the Waist

Carrying more weight around your middle can increase your risk of insulin resistance. Weight gain in this area is often linked to metabolic issues, including prediabetes.

Risk Factors for Prediabetes

Some people are more likely to develop prediabetes due to lifestyle or genetic factors. Here are some things to consider when assessing your personal risk:

  • Being Overweight or Obese: Excess weight, especially around the abdomen, increases your risk.
  • Age: People over 40 years old are more likely to develop prediabetes.
  • Lack of Physical Activity: A sedentary lifestyle can lead to insulin resistance.
  • Family History: If you have a parent or sibling with type 2 diabetes, your risk is higher.
  • Ethnicity: People of South Asian, African-Caribbean, and Black African descent are more prone to prediabetes.
  • Polycystic Ovary Syndrome (PCOS) and Gestational Diabetes during pregnancy also increase your risk.

How to Prevent Prediabetes

The silver lining is that prediabetes is reversible through lifestyle changes. Even modest adjustments can drastically reduce your risk of developing type 2 diabetes. Here’s what you can do to take control of your health.

1. Adopt a Balanced Diet

Your diet plays a pivotal role in blood sugar regulation. Swap out highly processed foods and sugary drinks for nutrient-rich, whole foods.

  • Focus on Complex Carbs: Replace white bread, pasta, and rice with whole grains like quinoa, oats, and brown rice.
  • Increase Fibre Intake: Foods high in fibre (such as vegetables, legumes, and fruits) slow down the release of sugar into your bloodstream.
  • Include Healthy Fats: Avocados, nuts, seeds, and olive oil can help balance your diet.
  • Portion Control: Keeping an eye on portion sizes reduces the likelihood of overeating and spiking blood sugar levels.

2. Get Active (and Stay Active!)

Exercise is one of the best ways to combat insulin resistance, as it helps your body use glucose more effectively. Aim for 150 minutes of moderate activity each week, as advised by the NHS. This could include brisk walking, swimming, or cycling.

Strength training is also beneficial. By building muscle mass, you improve your body’s ability to manage insulin and keep blood sugar levels normal.

3. Lose Excess Weight

Numerous studies show that losing just 5–7% of your body weight can significantly lower the risk of prediabetes progressing to diabetes. Small, sustainable changes are key, so focus on gradual lifestyle adjustments rather than quick fixes.

4. Monitor Your Blood Sugar

If you have risk factors for prediabetes, regular blood sugar checks are essential. Speak to your GP about getting tested if you’re concerned. Routine checks can help catch any rising levels early, giving you the opportunity to take preventive action.

5. Manage Stress Levels

Chronic stress can wreak havoc on your blood sugar by promoting the release of stress hormones like cortisol, which can raise glucose levels. Practices like yoga, meditation, or simply disconnecting for a few moments each day can make a big difference.

6. Avoid Smoking and Excessive Alcohol

Both smoking and frequent alcohol consumption are linked to insulin resistance and can contribute to the development of prediabetes. Cutting back can protect your health and improve your energy levels.

Why Early Prevention Matters

Preventing prediabetes isn’t just about avoiding type 2 diabetes. Taking control of your health also lowers your risk of cardiovascular complications, keeps your metabolism functioning optimally, and boosts your overall quality of life.

Conclusion

Prediabetes may feel daunting, but it’s a condition you can turn around. Small, consistent changes lead to big results, so take a moment today to evaluate your risk factors and put a plan into action.
