Overview

The two most sensitive and specific tests used in confirming the clinical suspicion and in diagnosing Dumping syndrome. They are the oral glucose tolerance test and the Hydrogen breath test.

Diagnostic Study of Choice

Study of choice:

Oral glucose tolerance test is the study of choice for the diagnosis of early dumping syndrome and late dumping syndrome.
A mixed-meal tolerance test is the study of choice for the diagnosis of late dumping syndrome.

The comparison table for diagnostic studies of choice for Dumping syndrome


Table	Sensitivity	Specificity
✔ Oral glucose provocation	100%	92%
Hydrogen breath	100%	?

✔= The best test based on the feature

Diagnostic results

The following result of the oral glucose tolerance test is confirmatory of dumping syndrome:

An increase in the heart rate by 10 beats per minute or more in the first hour after an oral glucose challenge of 50 grams glucose after fasting for 10 hours.

The following result of the Hydrogen breath test is confirmatory of dumping syndrome:

A positive Hydrogen breath test after glucose ingestion.

Diagnostic Criteria

Oral glucose tolerance test
The patient fasts overnight. An oral glucose load of 50 grams or 75 grams in solution is given. Readings of the heart rate and blood pressure are taken before the ingestion Blood is drawn before the ingestion. Then after ingestion, every 30 minutes until 180 minutes, readings and blood are taken. If the patient has an

 === Diagnostic Criteria ===
-* Here you should describe the details of the diagnostic criteria.
+{| class="wikitable"
-*Always mention the name of the criteria/definition you are about to list (e.g. modified Duke criteria for diagnosis of endocarditis / 3rd universal definition of MI) and cite the primary source of where this criteria/definition is found.
+!Oral glucose tolerance test
-*Although not necessary, it is recommended that you include the criteria in a table. Make sure you always cite the source of the content and whether the table has been adapted from another source.
+|-
-*Be very clear as to the number of criteria (or threshold) that needs to be met out of the total number of criteria.
+|
-*Distinguish criteria based on their nature (e.g. clinical criteria / pathological criteria/ imaging criteria) before discussing them in details.
+* The patient fasts overnight.
-*To view an example (endocarditis diagnostic criteria), click [[Endocarditis diagnosis|here]]
+* An oral glucose load of 50 grams or 75 grams in solution is given.
-*If relevant, add additional information that might help the reader distinguish various criteria or the evolution of criteria (e.g. original criteria vs. modified criteria).
+* Readings of the heart rate and blood pressure are taken before the ingestion
-*You may also add information about the sensitivity and specificity of the criteria, the pre-test probability, and other figures that may help the reader understand how valuable the criteria are clinically.
