Diabetes is a well-known metabolic illness that affects millions of people worldwide. But have you ever heard of borderline diabetes or prediabetes? Well, it is a condition that often goes unnoticed but is worth paying attention to. 

Prediabetes is a warning sign that your body's sugar processing system is not working optimally, and you may encounter type 2 diabetes (T2D) in the future. Essentially, it means that your blood sugar is higher than usual but not yet at a level that would warrant a type 2 diabetes diagnosis. 

Now, you might be wondering, "Why should I care about borderline diabetes?" The answer is simple: Prevention is far better than cure, and it is much easier to manage prediabetes than type 2 diabetes. So, in this blog, we'll dive deeper into the world of prediabetes or borderline diabetes and equip you with the knowledge you need to stay ahead of the game.

What Is Borderline Diabetes?

As the name suggests, borderline diabetes means that it is a stage where the blood sugar level of the individual is not in the recommended range but is also not that high to term it diabetes. Basically, it is an intermediate condition that indicates or simply warns the person about the future diabetes condition.

As type 2 diabetes is closely linked with cardiovascular disorders, the person suffering from prediabetes has a higher chance of getting heart disease. To understand it properly, you should be aware of HbA1c levels in the body. It is the average blood glucose (sugar) levels for the last two to three months. The different levels of HbA1c include

A1C Level (%)


< 5.7

No diabetes

5.7 - 6.4

Prediabetes (increased risk of developing diabetes)

How To Treat Borderline Diabetes?

Some useful options to treat borderline diabetes or prediabetes include the following:

1. Regular Physical Activity

Moreover, it also benefits managing your weight and overall fitness, thus reducing the risk of borderline diabetes. Some easy-to-do exercises are:

  • Brisk walking 

  • Swimming 

  • Yoga 

  • Cycling ‘

  • Dancing 

2. Eating A Balanced Diet  

Curing and treatment depend on what we eat and how much we consume. To cure prediabetes, you must limit your intake of refined carbohydrates like pasta, white bread, saturated fats, and sugary foods.   

Instead, you should start eating healthy foods like fresh fruits, vegetables with low glycemic index, lean proteins and whole grains. 

3. Weight Management

Overweight is the leading and foremost cause of prediabetes and cardiovascular disorders. To prevent this, you can modify your diet plan by adding detox drinks for weight loss or herbal teas for losing weight. These low-calorie drinks are effective in achieving the desired weight, thus preventing the risk of borderline diabetes. Some of the low-calorie drinks are:

  • Green tea

  • Cinnamon tea

  • ​​Lemon water​

  • ​​Ginger tea​

  • ​​Coconut water​

  • Regular water
