Comparing Diabetes & Prediabetes

Diabetes and prediabetes are two closely related conditions that involve the body’s ability to regulate blood sugar levels. However, while diabetes is a chronic condition that often requires long-term medical treatment, prediabetes is an early warning sign that your body is struggling with blood sugar control.

It is a crucial stage where intervention can help prevent the development of full-blown diabetes. Understanding the differences between these two conditions is essential for preventing long-term health complications, as prediabetes can often be reversed with lifestyle changes, while diabetes typically requires ongoing management.

In this article, you will learn the key differences between prediabetes and diabetes, how they are diagnosed, their symptoms, and the steps you can take to prevent prediabetes from progressing into diabetes.

What Is Prediabetes and How Is It Different From Diabetes?

Prediabetes is a condition where your blood sugar levels are higher than normal but not high enough to be classified as type 2 diabetes. It’s essentially an early warning that your body is beginning to lose its ability to process glucose efficiently. The key difference between prediabetes and diabetes lies in blood sugar levels. A fasting blood sugar level of 100-125 mg/dL indicates prediabetes, while a level of 126 mg/dL or higher signifies diabetes. Both conditions are linked to insulin resistance, where the body doesn’t respond properly to insulin, a hormone crucial for managing blood sugar levels.

In prediabetes, your body still produces enough insulin, but it becomes less effective at lowering blood sugar. In type 2 diabetes, insulin production often declines, and the body struggles to manage glucose levels. Over time, this can lead to more severe complications such as kidney disease, nerve damage, and vision problems.

As a Carbon Health expert explained, “As many as 90% of people with prediabetes don’t know they have it,” which is why regular screenings for people over the age of 35 are crucial for early detection.

What Are the Symptoms of Prediabetes vs. Diabetes?

Most people with prediabetes don’t experience noticeable symptoms, which makes it difficult to identify without a blood test. This is why regular screening is essential, especially if you have risk factors like being overweight or having a family history of diabetes. However, once prediabetes progresses to type 2 diabetes, symptoms can start to appear.

Symptoms of diabetes include:

• Excessive thirst (polydipsia)
• Frequent urination (polyuria)
• Excessive hunger (polyphagia)
• Unintended weight loss

These symptoms occur because high blood sugar levels cause the body to expel sugar through urine, leading to dehydration and constant hunger. Other symptoms of diabetes include:

• Blurred vision
• Slow-healing sores
• Numbness or tingling in the hands and feet

In contrast, prediabetes typically remains symptomless until it progresses to diabetes, underscoring the importance of early testing and detection.

Can Prediabetes Be Reversed?

Yes, prediabetes can be reversed, primarily through lifestyle changes. Prediabetes is a condition that signals that your blood sugar levels are higher than normal, but not yet in the diabetic range. This stage is considered reversible because the pancreas still produces sufficient insulin, and the body can regain its ability to manage blood sugar effectively with the right interventions. Reversing prediabetes generally involves losing weight, increasing physical activity, and making dietary changes.

Research shows that losing just 5% to 7% of body weight can lower the risk of progressing from prediabetes to diabetes by up to 58%. For example, a person weighing 200 pounds would only need to lose 10 to 14 pounds to achieve significant health benefits. Regular physical activity, such as 30 minutes of brisk walking five times a week, can improve insulin sensitivity and help control blood sugar levels.

A healthy diet is another crucial factor in reversing prediabetes. Reducing the intake of processed carbohydrates and sugary foods while incorporating whole grains, lean proteins, fruits, and vegetables can help stabilize blood sugar levels. A study showed that people who made these lifestyle changes were much less likely to develop type 2 diabetes over a 10-year period than those who did not.

However, once prediabetes progresses into type 2 diabetes, the condition becomes much harder to reverse, especially after years of damage to the pancreas and insulin production. In some cases, early-stage diabetes can be managed or even put into remission with significant lifestyle changes or intensive medical treatments, but long-term diabetes is generally considered chronic and irreversible.

What Are the Risk Factors for Prediabetes and Diabetes?

The risk factors for both prediabetes and diabetes largely overlap, but there are some key differences to note. Both conditions are influenced by lifestyle choices, genetics, and other health conditions, but prediabetes is seen as a precursor stage, meaning that catching it early and addressing these risk factors can prevent diabetes from developing.

For prediabetes, common risk factors include:

• Being overweight or obese: Excess weight, particularly around the abdomen, is a major contributor to insulin resistance. Fat around the organs (visceral fat) leads to chronic inflammation, which impairs insulin’s ability to work properly.

• Physical inactivity: Not getting enough exercise is linked to insulin resistance. Regular physical activity helps the body use insulin more efficiently and lowers blood sugar levels.

• Age: Being over 45 years old increases your risk of developing prediabetes, as insulin resistance tends to grow with age.

• Family history: Having a parent or sibling with type 2 diabetes increases the likelihood of developing prediabetes or diabetes.

• Gestational diabetes: Women who had diabetes during pregnancy have an increased risk of developing prediabetes and type 2 diabetes later in life.

• Polycystic ovary syndrome (PCOS): This condition in women is associated with insulin resistance, making it a risk factor for prediabetes.

For diabetes, many of the same risk factors apply, but the chances of developing full diabetes increase significantly if prediabetes is left untreated. Additional risk factors for type 2 diabetes include:

• Ethnicity: Certain ethnic groups, including African Americans, Hispanics, Native Americans, Asian Americans, and Pacific Islanders, are at a higher risk for developing type 2 diabetes.

• High blood pressure and high cholesterol: These conditions often accompany diabetes and can exacerbate insulin resistance.

• History of cardiovascular disease: People with heart disease are at an increased risk of developing type 2 diabetes, as both conditions share similar risk factors, such as obesity and inactivity.

How Is Prediabetes Diagnosed Differently Than Diabetes?

Both prediabetes and diabetes are diagnosed using the same blood tests, but the results differ. The most common tests include fasting plasma glucose (FPG), A1C, and oral glucose tolerance tests (OGTT).

Fasting Plasma Glucose (FPG): This test measures your blood sugar after an overnight fast of at least eight hours.

• A fasting blood sugar level of 100 to 125 mg/dL indicates prediabetes.
• A level of 126 mg/dL or higher is used to diagnose diabetes.

A1C Test: The A1C test measures your average blood sugar levels over the past two to three months. It doesn’t require fasting and provides a longer-term view of blood sugar control.

• An A1C level of 5.7% to 6.4% indicates prediabetes.
• A level of 6.5% or higher confirms a diagnosis of diabetes.

Oral Glucose Tolerance Test (OGTT): In this test, your blood sugar is measured two hours after drinking a sugary beverage.

• A reading of 140 to 199 mg/dL suggests prediabetes.
• A level of 200 mg/dL or higher indicates diabetes.

How Can You Prevent Prediabetes from Progressing to Diabetes?

Preventing prediabetes from turning into type 2 diabetes is possible with the right lifestyle changes and habits. Here are some effective strategies to reduce your risk:

• Adopt a Healthy Diet: A balanced diet rich in whole grains, vegetables, lean proteins, and healthy fats can help manage blood sugar levels. Avoid processed foods, sugary drinks, and refined carbs to maintain stable glucose levels.

• Increase Physical Activity: Regular physical activity, such as brisk walking, jogging, or strength training, can improve insulin sensitivity and help regulate blood sugar levels. Aim for at least 150 minutes of moderate exercise per week.

• Maintain a Healthy Weight: Losing even 5-7% of your body weight can significantly reduce the risk of developing diabetes. Focus on gradual weight loss through a combination of diet and exercise.

• Monitor Blood Sugar Levels: Regular monitoring of blood sugar levels helps you track progress and adjust your lifestyle if necessary. This is especially important if you’re at high risk or have been diagnosed with prediabetes.

• Quit Smoking: Smoking increases the risk of insulin resistance and contributes to the development of type 2 diabetes. Quitting smoking can improve overall health and reduce your risk.

• Limit Alcohol Consumption: Drinking too much alcohol can affect blood sugar levels and contribute to weight gain. Limit your intake to moderate levels—up to one drink per day for women and two for men.

• Manage Stress: Chronic stress can lead to poor blood sugar control. Practices like yoga, meditation, and deep breathing exercises can help reduce stress and prevent diabetes progression.

What Medications Are Used to Treat Prediabetes and Diabetes?

While lifestyle changes like diet and exercise are the first steps in managing prediabetes and diabetes, medications may be necessary in some cases, especially when lifestyle changes alone aren’t enough to control blood sugar levels.

Prediabetes Medications

There are currently no medications specifically approved to treat prediabetes, but some doctors may prescribe medications to lower blood sugar levels and reduce the risk of developing type 2 diabetes. The most common medication used for prediabetes is metformin. Metformin works by:

• Reducing the amount of sugar your liver releases into the bloodstream.
• Improving your body’s sensitivity to insulin, helping it lower blood sugar more effectively.

A study found that metformin can reduce the risk of developing diabetes by 31%, particularly in younger individuals and those with a higher body mass index (BMI). However, lifestyle changes are still more effective than medication in preventing diabetes.

Type 2 Diabetes Medications

For people with type 2 diabetes, several medications are used to control blood sugar levels, each working in different ways. Common medications include:

• Metformin: Often the first medication prescribed for type 2 diabetes, metformin helps reduce glucose production in the liver and increases insulin sensitivity.

• Glipizide and Glyburide: These medications stimulate the pancreas to release more insulin, helping to lower blood sugar levels.

• Liraglutide (Victoza) and Semaglutide (Ozempic): These injectable medications increase insulin production in response to meals and also help with weight loss.

• Tirzepatide (Mounjaro): A newer injectable medication that helps control blood sugar and promotes weight loss by mimicking hormones that regulate insulin and appetite.

• Insulin: For advanced stages of type 2 diabetes or cases where other medications are ineffective, insulin injections are often necessary to maintain proper blood sugar levels. There are different types of insulin, including long-acting options like insulin glargine (Lantus) and rapid-acting forms like insulin lispro (Humalog).
