Prediabetes Syndrome: A Pre-Cursor to Type 2 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 often considered a pre-cursor to type 2 diabetes, and if left untreated, can lead to the development of this serious health condition.

Characteristics of Prediabetes

• Elevated blood sugar levels that fall below the threshold to diagnose diabetes mellitus [7]
• Often accompanied by obesity, especially abdominal or visceral obesity [7]
• Dyslipidemia with high triglycerides and/or low HDL cholesterol [7]
• Hypertension (high blood pressure) [7]

Risk Factors

• Family history of type 2 diabetes
• Age: risk increases after the age of 45
• Physical inactivity
• Obesity, especially around the waistline
• History of gestational diabetes or delivering a baby over 4 kg

Consequences if Left Untreated

• Increased risk of developing type 2 diabetes [6]
• Higher risk of cardiovascular disease and stroke [8]
• Potential for kidney damage and other complications associated with diabetes [8]

Key Takeaways

Prediabetes is a serious condition that requires attention. By making lifestyle changes, such as maintaining a healthy weight, exercising regularly, and following a balanced diet, individuals can reduce their risk of developing type 2 diabetes and related complications.

Prediabetes Signs and Symptoms

Prediabetes, a precursor to Type 2 diabetes, often has no noticeable symptoms in its early stages. However, some people may experience subtle signs that can indicate the presence of this condition.

• Darkened skin: Some individuals with prediabetes may develop darkened skin on certain areas of their body, such as the neck, armpits, and groin [5][6].
• Increased appetite: Elevated appetite or polyphagia is another possible early sign of prediabetes [12].
• Weight changes: Unexplained weight loss or gain can be a symptom of both prediabetes and Type 2 diabetes [3].

It's essential to note that most people with prediabetes do not exhibit any symptoms, making it crucial for individuals at risk to undergo regular health checks by their doctor.

Classic signs and symptoms of Type 2 diabetes

While these are not specific to prediabetes, they can indicate a progression from prediabetes to Type 2 diabetes:

• Increased thirst
• Frequent urination
• Blurry vision
• Numbness or tingling in hands or feet [7]

Reversibility and prevention

Fortunately, prediabetes is reversible with healthy lifestyle changes, such as losing between 5-7% of body weight and increasing physical activity to 150 minutes per week [14]. Early detection and intervention can help prevent the progression to Type 2 diabetes.

Diagnostic Tests for Prediabetes Syndrome

Prediabetes is an intermediate stage before full-blown type 2 diabetes that needs to be identified and addressed immediately. The following diagnostic tests are commonly used to diagnose prediabetes:

• Fasting Plasma Glucose (FPG) Test: This test measures the amount of glucose in the blood after an overnight fast. A result between 100-125 mg/dL indicates prediabetes, while a result less than 100 mg/dL is normal and a result 126 mg/dL or higher indicates diabetes [3][7].
• A1C Test: This test measures the average blood glucose level over the past two to three months. A result between 5.7-6.4% indicates prediabetes, while a result less than 5.7% is normal and a result 6.5% or higher indicates diabetes [9].
• Oral Glucose Tolerance Test (OGTT): This test measures the body's ability to regulate blood sugar levels after consuming a sugary drink. The OGTT is considered the most accurate test for insulin resistance, but it is more expensive and less commonly used than the FPG or A1C tests [3].
• Random (Casual) Plasma Glucose Test: This test measures the amount of glucose in the blood at any time of day. While not as commonly used as the other tests, a result between 100-125 mg/dL may indicate prediabetes [8].

It's worth noting that each diagnostic test has its advantages and disadvantages, and a repeat confirmatory laboratory test is often required to confirm a diagnosis of prediabetes or diabetes [13].

Medications for Prediabetes

Prediabetes, an intermediate stage between normal glucose regulation and diabetes, can be managed with lifestyle changes, but in some cases, medications may also be prescribed to prevent the progression to Type 2 diabetes.

• Metformin: The most commonly prescribed medication for prediabetes is metformin, a biguanide that reduces insulin resistance and decreases blood sugar levels. Studies have shown that metformin can decrease the risk of progression to type 2 diabetes by up to 80% [5][6].
• Other medications: Thiazolidinediones (TZDs), acarbose, orlistat, GLP-1 receptor agonists, and SGLT2 inhibitors may also be prescribed in some cases, particularly if lifestyle changes are not enough to prevent the progression to Type 2 diabetes [7][8].

Important Considerations

• Lifestyle changes: While medications can help, major lifestyle changes such as losing weight, eating healthier foods, and getting more exercise are still essential for preventing the progression to Type 2 diabetes.
• Safety and efficacy: Metformin is considered a safe and cost-effective treatment option for prediabetes, but it's essential to discuss potential risks and benefits with a healthcare provider [9][10].

Metformin, acarbose and orlistat also reduce incident diabetes, but ...

Medications — like metformin — can help prevent Type 2 diabetes in some people with prediabetes.

Differential Diagnosis of Prediabetes Syndrome

Prediabetes syndrome, also known as impaired glucose tolerance or impaired fasting glucose, can be challenging to diagnose due to its subtle symptoms and similarities with other metabolic disorders. Here are some key points to consider in the differential diagnosis of prediabetes syndrome:

• Metabolic Syndrome: Metabolic syndrome is a cluster of conditions that increase the risk of developing type 2 diabetes and cardiovascular disease. It includes central obesity, high blood pressure, elevated triglycerides, low HDL cholesterol, and impaired glucose regulation (1). Prediabetes syndrome often co-exists with metabolic syndrome.
• Impaired Glucose Tolerance: Impaired glucose tolerance is a condition where the body's ability to regulate blood sugar levels is compromised. It can be caused by various factors, including insulin resistance, pancreatic beta-cell dysfunction, and genetic predisposition (9).
• Impaired Fasting Glucose: Impaired fasting glucose refers to elevated blood glucose levels after an overnight fast. This condition can be a precursor to diabetes mellitus and often co-exists with other metabolic disorders (10).
• Other Conditions: Besides prediabetes syndrome, several other conditions can cause elevated blood sugar levels and/or symptoms of hyperglycemia, such as:
  • Diabetes mellitus
  • Pancreatitis
  • Cushing's syndrome
  • Polycystic ovary syndrome (PCOS)
  • Hypothyroidism
  • Certain medications (e.g., steroids, beta-blockers) (7)

Key Diagnostic Criteria

To diagnose prediabetes syndrome, healthcare providers consider the following criteria:

• A1C level: An A1C level of 5.7% to 6.4% indicates impaired glucose regulation and is a diagnostic criterion for prediabetes (13).
• Fasting plasma glucose: A fasting plasma glucose level of 100 mg/dL to 125 mg/dL suggests impaired fasting glucose and may indicate prediabetes (10).

Risk Factors

Several risk factors increase the likelihood of developing prediabetes syndrome, including:

• Obesity: Central obesity is a significant risk factor for prediabetes syndrome.
• High cholesterol: Elevated triglycerides and low HDL cholesterol levels are associated with an increased risk of prediabetes.
• Hypertension: High blood pressure can contribute to the development of prediabetes.
• Sleep problems: Poor sleep quality and duration may increase the risk of developing prediabetes (4).

Screening and Testing

Screening for prediabetes syndrome involves assessing an individual's risk factors, such as age, weight, physical activity level, and family history. If a person has one or more risk factors, healthcare providers may recommend testing for impaired glucose regulation using an A1C test or a fasting plasma glucose test (12).
