How Do Doctors Test for Hypoglycemia?
Published: Dec 30, 2023
If you suspect hypoglycemia, understanding the testing process is crucial. Learn how doctors confirm and understand this condition.
The Importance of Supervised Testing
Supervised testing is crucial for diagnosing hypoglycemia accurately. It involves monitoring patients under medical supervision to document Whipple's triad, which includes symptoms, low glucose levels, and symptom relief after sugar intake. This testing helps determine the underlying cause of hypoglycemia.
Different Types of Tests
There are two main types of tests: the supervised fast and the mixed-meal test. The supervised fast is typically used for fasting hypoglycemia, while the mixed-meal test is for postprandial (after eating) hypoglycemia. Each test helps identify whether insulin or other factors cause the condition.
What Happens During a Test?
During these tests, doctors monitor glucose levels and other markers like insulin and C-peptide. In a supervised fast, the patient may go without food for up to 72 hours, while in a mixed-meal test, they consume a meal to see how their body reacts. These tests help pinpoint the cause of hypoglycemia.
