What Is a 2-Hrs Post-Dinner Blood Sugar Test?
The 2-Hrs Post-Dinner Blood Sugar (PPBS) Test measures the level of glucose in your blood exactly two hours after eating dinner. During this time, your body digests food and releases glucose into the bloodstream. A healthy body efficiently uses insulin to bring sugar levels back to normal.
If blood sugar remains high even after two hours, it may indicate problems with insulin production or insulin usage.
Why Is the 2-Hrs Post-Dinner Test Important?
Many people have normal fasting blood sugar but abnormal post-meal readings. This is why the 2-Hrs Post-Dinner test is crucial.
