Do you need an empty stomach to check stomach problems?

Gastroscopy usually requires fasting.

Gastroscopy, C13 breath test, C14 breath test and other examinations are usually required. If the patient eats before gastroscopy, food will block the line of sight, which is not conducive to the doctor's observation and judgment. If the patient eats before C13 breath test, C4 breath test and other examinations, it will affect the numerical value, which is not conducive to the doctor's judgment. Therefore, gastroscopy usually requires fasting.

Patients are prohibited from eating after 8 pm the day before the examination, otherwise it will affect the examination results, resulting in inaccurate examination results.
