Helicobacter Pylori Tests
How It Feels continued...
You may experience some gagging, nausea, bloating, or mild
abdominal cramping as the tube is moved. Even though you won't be able to talk
during the procedure because you have a tube in your throat, you can still
communicate. If the discomfort is severe, alert your doctor with an agreed-upon

The IV medicines will make you feel sleepy. Other side
effects—such as heavy eyelids, difficulty speaking, a dry mouth, or blurred
vision—may last for several hours after the test. The medicines may also

other medicines that thin your blood can make bleeding more likely. If you have
bleeding or clotting problems, or if you take blood-thinning medicine, tell

if you do not wash your hands well after collecting the sample, you may spread
There is a slight risk (1 in 10,000) of puncturing the wall of
esophagus , stomach, or duodenum during an endoscopy to
collect stomach biopsy samples. The biopsy may also cause some bleeding at the
site where the samples are collected. But the bleeding usually stops
without treatment. To learn more, see the topic Upper Gastrointestinal Endoscopy.
