Why Postprandial Blood Sugar Matters If You Dont Have Diabetes
Avoiding progression to prediabetes or Type 2 diabetes arent the only reasons to pay attention to postprandial blood glucose. Elevated postprandial blood sugar can also be a predictor of cardiovascular disease mortality and atherosclerosis in people without diabetesand its a better indicator than fasting blood sugar. In fact, in individuals at greater risk for cardiovascular events, postprandial blood sugar levels are often high even when fasting blood sugar levels are unremarkable.
There are a few reasons for this connection to cardiovascular risk. Frequent episodes of postprandial hyperglycemia leads to the production of free oxygen radicals, also known as oxidants/oxidative stress, which are highly reactive molecules that can damage cells, and in particular, the mitochondria. The mitochondria, the part of the cell that produces energy , cannot keep up with a high metabolic load, and generates these free oxygen radicals, which build up over time, eventually overwhelming the bodys antioxidant capabilities, and causing metabolic dysfunction.
When To See A Doctor
If you experience symptoms of low blood sugar after eating, its best to talk with a doctor to determine the cause and the best course of treatment.
A doctor will ask questions about your symptoms and medical history. Additional testing may also be required, especially if you have severe symptoms or if an underlying condition may be contributing to your symptoms.
It might also be beneficial to keep track of the foods that you eat by completing a food diary, particularly if you experience anxiety after eating.
A doctor or dietitian can help identify any patterns that may contribute to your symptoms and provide suggestions for dietary modifications that may be beneficial.
Conditions That Can Mimic Hypoglycemia
Conditions other than hypoglycemia can have some of the same symptoms, including dizziness, weakness, sweating, and rapid heartbeat.
These include a wide variety of conditions, such as:
To decide if your symptoms are due to hypoglycemia, your healthcare provider will look for signs of the “Whipple Triad.”
- Low plasma glucose measurements while you have symptoms
- No symptoms when your glucose increases to normal levels
Without these three indications, your healthcare provider will likely evaluate you for other conditions that have similar symptoms.

When Might You Get A Postprandial Blood Sugar Test
Postprandial blood sugar testing is traditionally recommended for those who are already known to have impaired glucose control. Some scenarios include:
- Elevated fasting blood sugars and/or HbA1c tests may lead your physician to recommend a postprandial blood sugar test to better understand your level of glucose tolerance or to confirm a diabetes diagnosis.
- A person actively managing Type 1 diabetes may undergo a postprandial glucose test to assess whether theyre taking the right amount of insulin after meals and to help prevent potential diabetes complications.
- Pregnant women undergo postprandial glucose testing during weeks 24-28 of pregnancy to screen for gestational diabetes.
Today, its also common for healthy individuals to use postprandial blood sugar tests for nutritional and wellness insights. Postprandial blood sugar can help you understand how your body responds to a specific food or foods. A 2020 study found that there is large variability among people in postprandial glucose response even when they ate the same meal. However, people tended to have the same response to a meal every time they ate it, highlighting the importance of dietary recommendations that cater to a single person versus a one-size fits all approach.

Question : What Additional Research Needs To Be Performed To Clarify The Role Of Ppg In The Medical Management Of Diabetes
There are several issues that should be considered when designing studies to examine PPG. Studies should be performed in well-defined patient groups at a minimum, separation of patients by type of diabetes is necessary. It is also quite likely that results of studies in patients with impaired fasting glucose and/or impaired glucose tolerance may be different from those in patients with type 2 diabetes and different degrees of fasting hyperglycemia. In particular, elderly patients, in whom postprandial hyperglycemia may be the most prevalent abnormality in glucose homeostasis, may warrant special attention. In studies of the impact of PPG on diabetic complications, it is important to differentiate between microangiopathy and macroangiopathy as end points. Finally, attention must be paid to differences in therapeutic programs and type of oral glucose-lowering drugs used. Given these general principles, the following specific questions should be addressed:
Because CVD is the major cause of morbidity and mortality in patients with diabetes, and in type 2 diabetes in particular, understanding the impact on CVD events of treatments directed at specifically lowering PPG is crucial. Furthermore, the relationship between PPG excursions and both the well-established risk factors and the more recently identified putative mechanisms for CVD should be examined.
What Is The Importance Of Ppbs
The PPBS test is an important parameter in diabetes management. Generally, after 10 minutes of starting your meal, the blood sugar level starts increasing and it is at its peak approximately 2 hours after your meal. The PPBS blood test helps doctors analyze how your body responds to sugar and starch that you intake. The level of PPBS helps evaluate how well you are able to manage your diabetes. It also gives a better idea of what measures should be taken in the future, to control sugar levels. PPBS helps in achieving long-term goals. It also acts as an independent risk factor for various cardiovascular diseases.

What Are Blood Sugar Targets
A blood sugar target is the range you try to reach as much as possible. These are typical targets:
- Before a meal: 80 to 130 mg/dL.
- Two hours after the start of a meal: Less than 180 mg/dL.
Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.
How To Measure Your Spikes
The American Diabetes Association recommends you check your blood sugar levels right before mealtime with a blood sample from a finger stick. Then do it again 1 to 2 hours after that first bite of food.
Keep this up for a week or so. Write down the time and the blood sugar number. Make a note about anything you think might affect your levels, like medicine or exercise. And don’t forget to log exactly what you ate, along with portion sizes and the amount of carbs.What levels are too high after a meal? Experts vary on what the number should be, but the ADA says a general goal is a blood sugar level under 180 mg/dL, 1 to 2 hours after a meal. Talk to your doctor about what you should aim for, and don’t adjust your medicine without speaking to them first.

Measures Blood Glucose Levels Two Hours After Glucose Intake
This blood glucose test measures the amount of a type of sugar called glucose in your blood. Blood glucose levels that remain high over time can damage your eyes, kidneys, nerves and blood vessels.
A blood glucose test measures the amount of a type of sugar, called glucose, in your blood. Glucose comes from eating carbohydrates in food and is the main source of energy used by the body.
Normally, your blood glucose levels increase slightly after you eat. This increase causes your pancreas to release insulin so that your blood glucose levels do not get too high. Blood glucose levels that remain high over time can damage your eyes, kidneys, nerves, and blood vessels.

How Knowing Your Ppg Can Give You Control Over Your Diabetes
Information on PPG can help you troubleshoot in important ways. When blood sugar spikes after meals, and stays high, it can be hard to get levels back down to where you want them, according to the American Association of Clinical Endocrinologists . If your A1C continues to be higher than your target goal, your risk for developing complications rises.
By measuring PPG, we can determine whether dietary modifications or pre-meal bolus insulin is needed to reduce these spikes, Kumar says. In patients who achieve their pre-meal glucose targets but whose A1C remains above target, PPG monitoring and therapy is recommended.
Learning how to count carbohydrates can help you achieve your goals for blood sugar levels after eating.
Carbohydrates contribute significantly more to PPG than fat and protein content of a meal, Kumar says. Checking PPG regularly can help you figure out the best balance of carbohydrates, fats, and proteins.
If youre using insulin, talk to your doctor about what to do if your PPG levels are higher or lower than your goal, the AACE says.

What Other Tests Might I Have With This Test
Your healthcare provider may order other tests to confirm or evaluate whether you have diabetes. These may include:
Fasting blood glucose test.This measures the amount of sugar in your blood when you have not eaten for at least 8 hours.
Hemoglobin A1C test. This measures your average blood sugar level over the last 2 to 3 months.
Glucose tolerance test. This measures your body’s ability to use sugar after drinking a standard amount in a sugary drink.
Question : What Is The Relationship Among Ppg Fpg And Hba1c
Hemoglobin A1c is a measure of the degree to which hemoglobin is glycosylated in erythrocytes and is expressed as a percentage of total hemoglobin concentration. It reflects the exposure of erythrocytes to glucose in an irreversible and time- and concentration-dependent manner. HbA1c levels provide an indication of the average blood glucose concentration during the preceding 23 months, incorporating both pre- and postprandial glycemia.
Because blood glucose concentrations vary widely during a 24-h period and from day to day in diabetes, the measurement of HbA1c is the most accepted indicator of long-term glycemic control. However, the HbA1c level does not provide a measure of the magnitude or frequency of short-term fluctuations of blood glucose, which are particularly great in type 1 diabetes.
The relative contributions of FPG and PPG to HbA1c have been studied only recently. Data from several large cohorts with either type 1 or type 2 diabetes were presented at the conference. In general, FPG, PPG, and especially mean plasma glucose concentrations, defined by the average of multiple measurements of glucose taken throughout the day, are highly correlated with HbA1c. In contrast, postprandial glucose excursions , defined as the change in glucose concentration from before to after a meal, and the incremental glucose area, defined as the area under the glucose curve that is above the premeal value, are poorly correlated with HbA1c.
