Extended glucose tolerance test

[Hodge1960]

Advise please..
I am booked in next month for an extended glucose tolerance test. What can I expect and roughly how long will it take ?
Thank you in advance for any information.

I see that no-one answered your query. I didn't because I have never heard of an extended glucose tolerance test so I couldn't advise. The regular OGTT means fasting from the night before, measuring your blood sugar, drinking a sweet drink and sitting for two hours when they measure your sugar again. They could take other interim readings.

"Extended" sounds like it could go on a bit.

Have they told you what they are testing you for?
And how long the test will be?

I have heard of extended OGTTs that are 5 hours or 3 days, depending on the reason they are running it. The usual length is 2 hours.

If you google you can find the instructions used by health care professionals when they run the test, and the expected results, which should fill in your knowledge.

I am unsure if this applies to you or if you will find it useful.

Extented OGTT is sometimes used fofor the followig.

• Investigation of recurrent episodes of hypoglycaemia in non-diabetic patients

• The late dumping syndrome is suspected in the person who has symptoms of hypoglycaemia in the setting of previous gastric surgery
