High Fasting Blood Sugar Levels

What is High Fasting Blood Sugar?

Definition of high fasting blood sugar

High fasting blood sugar refers to elevated levels of glucose (sugar) in the bloodstream after a period of fasting. Fasting blood sugar is typically measured when you haven’t eaten for at least 8 hours. Elevated fasting blood sugar levels may indicate insulin resistance, uncontrolled diabetes, or other underlying health conditions.

Normal range of fasting blood sugar

In general, a normal fasting blood sugar level is considered to be between 70 and 99 milligrams per deciliter (mg/dL). However, this range may vary slightly depending on the testing laboratory and individual circumstances. It’s important to consult with a healthcare professional to determine the specific target range for your fasting blood sugar.

When fasting blood sugar levels are considered high

Fasting blood sugar levels are considered high when they consistently measure above 100 mg/dL. A diagnosis of prediabetes is often made if fasting blood sugar levels range between 100 and 125 mg/dL, and a diagnosis of diabetes is typically confirmed if fasting blood sugar levels consistently measure 126 mg/dL or higher on multiple occasions.

Causes of High Fasting Blood Sugar

Insulin resistance

Insulin resistance is a condition where cells become less responsive to the effects of insulin, a hormone necessary for the regulation of blood sugar levels. When insulin resistance occurs, the body may produce more insulin to compensate, leading to high fasting blood sugar levels. Factors such as obesity, sedentary lifestyle, and certain genetic factors can contribute to the development of insulin resistance.

Uncontrolled diabetes

Individuals with diabetes may experience high fasting blood sugar levels if their condition is not well-managed. In type 1 diabetes, the body does not produce enough insulin, while in type 2 diabetes, the body cannot effectively use the insulin it produces. Poor medication management or lack of adherence to a diabetes management plan can lead to elevated fasting blood sugar levels.

Medication side effects

Certain medications, such as corticosteroids and some antipsychotics, can increase blood sugar levels and contribute to high fasting blood sugar. It’s important to consult with your healthcare provider if you suspect that your medication may be affecting your blood sugar levels.

Stress and cortisol levels

Stress can elevate blood sugar levels by triggering the release of stress hormones, such as cortisol. Chronic stress can lead to prolonged elevated fasting blood sugar levels. Finding effective stress management techniques, such as exercise, meditation, or engaging in hobbies, can help lower stress levels and reduce the impact on blood sugar levels.

Lack of physical activity

Physical inactivity can contribute to high fasting blood sugar levels by reducing insulin sensitivity and impairing glucose uptake by muscles. Regular physical activity helps improve insulin sensitivity, allowing for better glucose control. Aim for at least 150 minutes of moderate-intensity exercise per week to help manage your blood sugar levels.

Inadequate sleep

Insufficient or poor-quality sleep can disrupt the body’s regulation of blood sugar levels, leading to high fasting blood sugar. Lack of sleep has been linked to insulin resistance, impaired glucose tolerance, and increased appetite. Establishing a consistent sleep schedule and practicing good sleep hygiene can support healthy fasting blood sugar levels.

Dietary factors

Certain dietary factors can contribute to high fasting blood sugar levels. Consuming an excessive amount of sugary or refined carbohydrate-rich foods without adequate fiber and protein can cause blood sugar levels to spike. Additionally, portion sizes, meal timing, and overall diet composition play a role in maintaining stable fasting blood sugar levels. Working with a registered dietitian can help you develop a healthy eating plan that promotes better blood sugar control.

Symptoms and Effects of High Fasting Blood Sugar

Common symptoms

Individuals with high fasting blood sugar levels may experience symptoms such as frequent urination, increased thirst, unexplained weight loss, blurred vision, fatigue, slow-healing wounds, and frequent infections. If you are experiencing any of these symptoms, it is important to consult with your healthcare provider for further evaluation.

Long-term effects on health

When high fasting blood sugar levels are left uncontrolled over time, they can lead to various chronic health conditions. These may include an increased risk of developing type 2 diabetes, cardiovascular disease, kidney damage, nerve damage (neuropathy), vision problems (retinopathy), and foot problems (diabetic foot ulcers). It is crucial to manage and control blood sugar levels to minimize the long-term effects on overall health.

Potential complications

If high fasting blood sugar levels are not addressed promptly, they can lead to acute complications such as diabetic ketoacidosis (DKA) in individuals with type 1 diabetes or hyperglycemic hyperosmolar syndrome (HHS) in individuals with type 2 diabetes. These conditions can be life-threatening and require immediate medical attention.

Diagnosing High Fasting Blood Sugar

Blood tests for fasting blood sugar levels

To diagnose high fasting blood sugar, a healthcare provider will typically order a fasting plasma glucose (FPG) test. This blood test is performed in the morning after an overnight fast. Results above 126 mg/dL on two separate occasions are indicative of diabetes. Results between 100 and 125 mg/dL may suggest prediabetes and should be followed up with further testing.

HbA1c test

Another blood test commonly used to assess blood sugar control is the hemoglobin A1c (HbA1c) test. This test measures average blood sugar levels over the past two to three months. A result of 6.5% or higher indicates diabetes, while a result between 5.7% and 6.4% suggests prediabetes.

Gestational diabetes screening

Pregnant individuals may undergo gestational diabetes screening to identify high fasting blood sugar levels during pregnancy. Screening may involve an initial one-hour glucose challenge test, followed by a three-hour glucose tolerance test if the first test indicates potential gestational diabetes.

Health Risks Associated with High Fasting Blood Sugar

Type 2 diabetes

Persistent high fasting blood sugar levels can progress to type 2 diabetes if left uncontrolled. Type 2 diabetes is a chronic condition characterized by elevated blood sugar levels, insulin resistance, and decreased insulin production.

Cardiovascular disease

High fasting blood sugar levels contribute to an increased risk of developing cardiovascular disease. Elevated blood sugar levels can damage blood vessels, leading to atherosclerosis (hardening and narrowing of the arteries), heart attacks, stroke, and other heart-related complications.

Kidney damage

Consistently high blood sugar levels can damage the small blood vessels in the kidneys, impairing their ability to filter waste from the blood. This can eventually lead to kidney disease or even kidney failure if blood sugar levels are not well-managed.

Nerve damage

High fasting blood sugar levels can damage the nerves throughout the body, leading to a condition called diabetic neuropathy. Symptoms may include numbness, tingling, burning sensations, and pain, particularly in the hands and feet.

Vision problems

Uncontrolled high fasting blood sugar levels can contribute to the development and progression of diabetic retinopathy, a condition that affects the blood vessels in the retina. It can lead to vision impairment and, in severe cases, blindness.

Foot problems

Poorly controlled blood sugar levels can affect the circulation and nerve function in the feet, increasing the risk of foot ulcers and infections. Individuals with diabetes should pay special attention to foot care, including proper hygiene and regular check-ups with a healthcare professional.
