Important points
- Regularly monitoring your fasting, postprandial, and A1C levels can help assess your blood sugar control and overall health.
- A fasting blood glucose test measures blood sugar levels after 8 hours without food or drink (except water) and is key to identifying prediabetes or diabetes.
- The A1C test reflects your average blood sugar levels over a 2-3 month period and can help guide your long-term management plan.
- Your blood sugar goals may vary depending on factors such as your age, health, and duration of diabetes.
- Monitoring and understanding your results can support lifestyle changes and treatments to prevent complications and improve your health.
fasting blood sugar level
Fasting blood glucose (also known as fasting plasma glucose or FPG) is blood sugar measured after at least 8 hours of fasting (no eating or drinking anything except water). The purpose of a fasting blood sugar test is to measure the amount of glucose (sugar) in your blood. This test is commonly used to check for diabetes or prediabetes. This test is usually done in a laboratory, clinic, or hospital. A blood sample is taken from a vein in your arm, collected in a tube, and analyzed at a laboratory. Alternatively, a blood sample can be taken by pricking your finger with a lancet.
Normal fasting blood sugar levels for people without diabetes
Normal fasting blood sugar for people without diabetes ranges from 70 to 99 mg/dl (3.9 to 5.5 mmol/l). of Recommended by the American Diabetes Association Regular screening for type 2 diabetes begins at age 35. If the results are normal, the screening should be repeated every three years.
Are overweight or obese, have a family history of type 2 diabetes, have a history of gestational diabetes, or are of a certain race/ethnicity (African American, Latino, Asian American, Pacific Islander, or Native American) American), You should get tested for diabetes early And it may be recommended to repeat the test more frequently.
Children and adolescents with symptoms of diabetes or who are overweight and have a family history of type 2 diabetes are African American, Latino, Asian American, Native American, or Pacific Islander and have prediabetes. There are signs of (acanthosis nigricans, Mothers with high blood pressure, high cholesterol) or gestational diabetes should be tested starting at age 10 or at the start of puberty (whichever comes first) and every three years thereafter.
Fasting blood glucose between 100 and 125 mg/dl (5.6 and 6.9 mmol/l) indicates prediabetes. This is a condition in which blood sugar levels are above “normal” but not high enough to be considered diabetes. Prediabetes is a risk factor for type 2 diabetes, heart disease, and stroke. It is managed with lifestyle changes and, in some cases, medications.
Official Fasting Blood Sugar ADA Recommendations for People with Diabetes
of Recommended by the American Diabetes Association The fasting blood glucose goal for most nonpregnant adults with diabetes is 80 to 130 mg/dl (4.4 to 7.2 mmol/l). However, targets for fasting blood glucose levels are individualized for specific people based on factors such as duration of diabetes, age and life expectancy, cognitive status, other health conditions, cardiovascular complications, and awareness of hypoglycemia. You may need to set it to . It is important for people with diabetes to discuss target blood sugar goals with their health care provider.
What is the normal blood sugar level after meals?
Postprandial blood sugar levels in people without diabetes
Normal blood sugar levels are less than 140 mg/dl. Blood sugar levels between 140 and 199 mg/dl (7.8 and 11.1 mmol/l) are considered prediabetic, and blood sugar levels above 200 mg/dl (11.1 mmol/l) may indicate diabetes. . People who don't have diabetes are unlikely to check their blood sugar levels. However, one screening test for diabetes is called the oral glucose tolerance test (OGTT). (A slightly different version of the OGTT is also used to diagnose gestational diabetes, which is diabetes that develops during pregnancy).
To perform this test, you must fast overnight and go to a doctor's office or lab in the morning. A blood sample is used to measure fasting blood sugar levels. The person then drinks a sugary drink containing 75 grams of sugar. Measure your blood sugar level again 2 hours later.
Normal blood sugar levels after meals in diabetics
of Recommended by the American Diabetes Association Most non-pregnant adults with diabetes need a blood sugar level below 180 mg/dl (10.0 mmol/l) 1 to 2 hours after starting a meal. This is usually the peak or highest blood sugar level for diabetics. Again, this goal is tailored to specific people based on factors such as duration of diabetes, age and life expectancy, cognitive status, other health conditions, cardiovascular complications, and awareness of hypoglycemia. You may need to personalize it. It is important for people with diabetes to discuss target blood sugar goals with their health care provider.
A1C
The A1C test is a blood test that shows your average blood sugar level over the past three months. Other names for this test are hemoglobin A1C, HbA1c, glycated hemoglobin, and glycated hemoglobin test. There is no need to fast before taking an HbA1C test. This means it's okay to eat or drink something beforehand. HbA1C tests may not be accurate for some people, such as people with anemia, people receiving treatment for HIV, and people of African, Mediterranean, or Southeast Asian descent. HbA1C results are reported as a percentage. The higher the percentage, the higher the blood sugar level.
HbA1C testing is not only a diagnostic tool for diabetes, but also helps diabetic patients manage their condition.
Normal HbA1c for people without diabetes
For people without diabetes, normal HbA1C levels are less than 5.7%. An A1C of 5.7% to 6.4% indicates prediabetes.
It is recommended that Adults over 45 years old Alternatively, adults under 45 who are overweight and have one or more risk factors for diabetes undergo a baseline A1C check. If the results are normal, your A1C should be tested every three years. If your results indicate prediabetes, you should have your A1C tested every 1 to 2 years.
A1C ADA Official Recommendations for People with Diabetes
of Recommended by the American Diabetes Association Most non-pregnant adults with diabetes have an A1C of less than 7%. Lower targets, such as less than 6.5%, may be appropriate for some people with short-lived diabetes, younger people, people without heart disease, and/or people with type 2 diabetes treated with lifestyle changes. there is. or metformin alone.
Higher A1C goals, such as less than 8%, are recommended for people with a history of severe hypoglycemia, limited life expectancy, advanced diabetes complications, other medical conditions, or lower A1C goals. May be suitable for those who have difficulty achieving it. It is important for people with diabetes to discuss target blood sugar goals with their health care provider.
Diabetics should check their A1C levels two to four times a year.
Blood sugar graph: overview
Fasting blood sugar levels, 2-hour postprandial blood sugar levels, and A1C testing are important ways to diagnose prediabetes and diabetes, and to show how well your diabetes is being controlled. If you think you have diabetes, it's important not to try to diagnose it yourself using a home blood glucose meter. There are strict criteria and procedures used by laboratories to diagnose diabetes. Therefore, you should get tested at your doctor's office or in a laboratory.
It is also important to talk to your doctor to make sure you understand: a) How often should you have certain tests, such as fasting blood sugar or A1C tests? b) What the results mean. c) What are your blood sugar and A1C goals?
If you have not been previously diagnosed with prediabetes or diabetes, but your results are above “normal,” your doctor should recommend other tests and discuss a treatment plan. Treatment may include lifestyle changes such as weight loss, a healthy eating plan, and regular physical activity. You may need to start taking diabetes medication, such as insulin.
If you've been diagnosed with diabetes, we recommend learning how to check your blood sugar levels with a meter so you and your healthcare team can determine how your treatment plan is working.
