Oral Glucose Tolerance Test
How It Feels
You may find it hard to drink the extremely sweet glucose liquid. Some people feel sick after drinking the glucose liquid and may vomit. Vomiting may prevent you from completing the test on that day.
The blood sample is taken from a vein in your arm. An elastic band is wrapped around your upper arm. It may feel tight. You may feel nothing at all from the needle, or you may feel a quick sting or pinch.
You may feel faint from having several blood samples taken in one day. But the amount of blood taken will not cause significant blood loss or anemia.
