PPBS (Postprandial Blood Sugar)
Understanding PPBS (Postprandial Blood Sugar)
What is PPBS (Postprandial Blood Sugar)?
The PPBS (Postprandial Blood Sugar) test measures the blood glucose (sugar) level after a meal, typically two hours after starting a meal. This test helps assess the risk for diabetes and check the effectiveness of the ongoing medication. It is often done as part of routine health checkups and when one experiences symptoms of altered blood sugar levels.
Glucose is the primary energy source for the body, and it is derived from the breakdown of carbohydrates in the food we consume. After the breakdown, glucose is absorbed into the blood and transported to the body's cells for energy. The blood glucose level is regulated by insulin, a hormone the pancreas produces. High blood glucose levels can result from a lack of insulin or its reduced effectiveness and can be a sign of diabetes or prediabetes (a condition where a person has high blood glucose levels but not yet at a level that qualifies as diabetes).
The PPBS (Postprandial Blood Sugar) test helps screen for prediabetes and diabetes and also checks the effectiveness of medications or lifestyle changes in people diagnosed with diabetes. Early detection and treatment of diabetes are important to prevent complications such as heart disease, kidney damage, and nerve damage. A PPBS test is typically done two hours after the start of a meal. Eating a standard meal that is not high in sugar or carbohydrates is important before the test. It is also important to inform the doctor about any medications you take, as some may affect blood glucose levels and need to be adjusted before the test.
Test result ranges are approximate and may differ slightly between labs depending on the methodology and laboratory guidelines. Talk to your doctor about your specific test results. The results will help the doctor determine your medical condition, make recommendations for lifestyle modifications such as diet and exercise, decide whether or not medication will be required to manage your condition and formulate your overall treatment plan.
What is PPBS (Postprandial Blood Sugar) used for?
The PPBS (Postprandial Blood Sugar) test can be done:
- As part of routine health checkups to measure the glucose level in the blood.
- If you have symptoms of altered blood glucose level, such as weight gain/loss, blurred vision, frequent urge to urinate, or confusion.
- To assess the risk for diabetes and prediabetes and monitor diabetes treatment.
- To screen pregnant women for gestational diabetes.
What does PPBS (Postprandial Blood Sugar) measure?
The PPBS (Postprandial Blood Sugar) test measures glucose levels in the blood two hours after a meal and is often performed with a fasting blood glucose test. This test measures how well your body can handle glucose after eating. It helps diagnose and monitor type 1 diabetes, caused by little or no insulin production, and type 2 diabetes, caused by insulin resistance or decreased insulin production. High postprandial blood sugar (PPBS) levels can indicate early insulin resistance, making your body less responsive to insulin.
Interpreting PPBS (Postprandial Blood Sugar) results
Interpretations
-
Normal: under 140 mg/dl (7.8 mmol/l)
-
Impaired glucose tolerance or Pre-diabetes: between 140 and 200 mg/dl (7.8 and 11.1 mmol/l)
-
Diabetes: equal to or above 200 mg/dl (11.1 mmol/l)
An oral glucose tolerance test is usually recommended when the blood glucose level falls between 140 and 200 mg/dl.
