Have you ever wondered what goes into getting your blood sugar levels checked, especially when you hear about fasting requirements? Preparing for a fasting plasma glucose (FPG) test can feel overwhelming, especially if you’re not used to skipping breakfast or adjusting your routine. However, understanding how to get ready for this common diabetes screening can make a big difference. This test provides critical insights into how your body manages sugar and whether you might be at risk for conditions like diabetes.
We spoke to our expert Dr Pranav A Ghody, Endocrinologist, Wockhardt Hospital, Mumbai Central, who listed the guidelines before taking the FPG test to ensure the most accurate results.
According to a 2017 study, diabetes, also known as diabetes mellitus, encompasses a group of metabolic disorders marked by chronic high blood sugar levels, which lead to disruptions in fat, carbohydrate, and protein metabolism. These disruptions occur due to issues with insulin release, insulin action, or both. The most prevalent form of diabetes mellitus is type 2 diabetes, a chronic condition that affects people globally.
Important Guidelines Before Taking Fasting Plasma Glucose Test
Preparation for the Test
To ensure the accuracy of the FPG test, you must fast for at least eight hours before your appointment. This means you should refrain from consuming any food or drinks, except for water. Drinking plenty of water not only helps maintain hydration but can also make the blood draw easier, as well-hydrated veins are often more accessible.
The purpose of fasting is to measure your blood sugar levels without interference from recent meals, which can cause temporary fluctuations. "Scheduling the test for the early morning can be a practical approach, as it allows for a longer fasting period overnight, making it easier to comply with the fasting requirement," said Dr Ghody.
Medications and Health Conditions
Before taking the FPG test, it’s important to discuss any medications you’re currently taking with your healthcare provider. Certain medications can impact blood sugar levels, potentially skewing your test results. Your doctor may provide specific instructions regarding their use before the test.
"Additionally, you should inform your healthcare provider about any underlying health conditions, particularly those related to blood sugar management, such as diabetes, hormonal disorders, or other metabolic issues. These conditions can influence test outcomes and may require special consideration in how the test is interpreted or how it should be conducted," added Dr Ghody.
Understanding Test Results
“Once the test is completed, the results will indicate your fasting plasma glucose levels. Generally, normal fasting plasma glucose levels range from 70 to 109 mg/dL. If your levels fall between 110 and 125 mg/dL, this indicates prediabetes, which signifies an increased risk of developing type 2 diabetes. A fasting plasma glucose level of 126 mg/dL or higher suggests that you may have diabetes,” explained Dr Ghody.
Your healthcare provider will review your results with you, helping you understand what they mean and any necessary next steps. If your results indicate prediabetes or diabetes, your doctor may recommend further testing or lifestyle changes to help manage your blood sugar levels effectively.

Post-Test Recommendations
"After completing the FPG test, you can resume your normal diet. It’s advisable to have a healthy meal prepared to stabilise your blood sugar levels. A balanced meal containing proteins, healthy fats, and complex carbohydrates can help regulate your glucose levels post-test," advised Dr Ghody.
Many people may feel hungry after fasting, and having a nutritious breakfast or lunch can prevent overeating or choosing unhealthy options. Moreover, if you have diabetes or are at risk of developing it, regular meals that balance blood sugar are crucial for overall health management.
