FAQs

• Can stress raise fasting sugar? Yes, stress can temporarily raise fasting blood sugar levels by triggering the release of hormones like cortisol and adrenaline, which increase glucose production in the body, but this effect usually resolves once stress is managed.
• Is fasting mandatory? Yes, fasting for at least 810 hours is mandatory for accurate FBS results, as it ensures the measurement reflects your body's baseline glucose levels without interference from recent food intake.
• Is one test enough for diagnosis? No, a single FBS test is not sufficient for a diabetes diagnosis; it typically requires confirmation with a repeat test on a different day or additional tests like an oral glucose tolerance test or HbA1c to rule out temporary fluctuations.
• Can medicines affect results? Yes, certain medications such as steroids, beta-blockers, or diuretics can affect FBS results by altering glucose metabolism, so it's important to inform your doctor about all current prescriptions before testing.
• How often should it be checked? It should be checked as advised by your doctor, typically every 13 years for screening in low-risk individuals or more frequently (e.g., quarterly) for those with diabetes or prediabetes to monitor control and adjust treatment.
