What's this test for?

This test is ideal if you're experiencing symptoms like excessive thirst, frequent urination, unexplained weight loss, or persistent fatigue that might indicate diabetes or prediabetes. It measures how well your body processes sugar over time, helping identify insulin resistance or blood sugar regulation problems. Many people use this test when they have risk factors like family history of diabetes, being overweight, or previous borderline blood sugar readings.

What happens after I get my results?

You'll receive doctor notes in simple language explaining what your glucose tolerance results mean for your diabetes risk and metabolic health. These notes include personalized recommendations like dietary changes, exercise routines, weight management strategies, or whether you should follow up with an endocrinologist. You'll also get the standard lab report and can track your glucose levels over time using our trends feature to monitor your progress as you make lifestyle adjustments.

What's included in this test?

This glucose tolerance test involves taking multiple blood samples over a specific time period after consuming a glucose solution. This test evaluates how your body handles glucose (sugar) over time by measuring blood sugar at intervals. It reveals whether your body can properly regulate blood sugar levels after consuming glucose, which is essential for diagnosing diabetes, prediabetes, or insulin resistance. This assessment provides crucial information about your metabolic health and risk for developing diabetes-related complications.

How should I prepare for this test?

You must fast for at least 8 hours before this test, which means no food or beverages except water during that time. This fasting period is essential for accurate results since it establishes your baseline glucose level. Schedule your test for early morning so you can fast overnight, and bring something to eat afterward since the test takes a few hours to complete.

Who should consider getting this test?

This test is important for people with diabetes risk factors including being overweight, having a family history of diabetes, being over 45 years old, or having conditions like high blood pressure or PCOS. It's also recommended for pregnant women to screen for gestational diabetes, and for anyone with symptoms like excessive thirst, frequent urination, or unexplained fatigue. If you've had borderline blood sugar levels in the past, this comprehensive test provides more detailed information than a simple glucose check.

What symptoms indicate I may need this test?

Common symptoms that suggest you may need glucose tolerance testing include excessive thirst and frequent urination, especially at night, unexplained weight loss despite normal eating, persistent fatigue or weakness, blurred vision, and slow-healing cuts or infections. You might also feel unusually hungry even after eating, experience tingling in your hands or feet, or notice dark patches of skin in body folds. These symptoms can indicate your body isn't processing sugar properly.

How can I naturally support healthy blood sugar levels?

Supporting healthy blood sugar starts with eating a balanced diet rich in fiber, lean proteins, and healthy fats while limiting refined carbohydrates and sugary foods. Regular physical activity like brisk walking for 30 minutes most days helps your body use insulin more effectively. Getting adequate sleep, managing stress, staying hydrated, and maintaining a healthy weight all contribute to better blood sugar control naturally.

What is glucose tolerance and why does it matter?

Glucose tolerance refers to your body's ability to remove sugar from your bloodstream and move it into cells where it's used for energy. When you have good glucose tolerance, your blood sugar rises moderately after eating and returns to normal quickly. Poor glucose tolerance means sugar stays elevated in your blood longer, which over time can damage blood vessels, nerves, and organs, leading to diabetes and its complications like heart disease, kidney problems, and vision loss.

What does high glucose on this test mean?

High glucose levels during the tolerance test indicate your body isn't efficiently processing sugar, which may mean you have prediabetes or diabetes. This happens when your pancreas doesn't produce enough insulin or your cells don't respond properly to insulin. Elevated readings suggest increased risk for serious health complications and signal the need for lifestyle changes or medical treatment to prevent progression to full diabetes.

How often should I retest my glucose tolerance?

If your results are normal but you have risk factors for diabetes, retesting every 1-3 years is recommended depending on your risk level. If you're diagnosed with prediabetes, your doctor will likely want to retest annually to monitor progression. For those managing diabetes or making significant lifestyle changes, your healthcare provider may recommend retesting every 3-6 months initially to track improvement and adjust treatment.
