Do I have to go on an empty stomach to check for stomach problems?

1, stool examination

stool examination can judge whether there are bacteria, parasites and other infections, but also can check whether there is bleeding, so as to rule out infection and gastric bleeding problems, generally do not need fasting, basically no impact on the results of the examination.

2, Helicobacter pylori detection

requires fasting examination, and fasting at least 2 hours, so as not to affect the accuracy of the examination.

3, gastroscopy

gastroscopy can check the shape of the stomach, generally need fasting, so as not to block the stomach structure, resulting in inaccurate results.
