Here is the translation:

  Gastroscopy, from mouth to stomach???? The first story "Abdomen" and the second story "Thin Stomach" mentioned that gastrointestinal diseases need to undergo gastroscopy.???? Gastroscopy uses a thin tube with a diameter of about 1 cm wrapped in black plastic, containing optical fibers, with an endoscope at the front end, inserted through the mouth into the esophagus → stomach → duodenum. With the light source, the doctor can clearly observe the health status of each part of the upper digestive tract from the other end. If necessary, a biopsy can be performed through a small hole in the gastroscopy tube. The entire examination takes about 10 minutes, and if a biopsy is performed, it takes 20-30 minutes.???? To undergo gastroscopy, the digestive tract must be clean, without food or blood clots. If the examination is performed in the morning, do not eat or drink anything after 8 pm the night before, and avoid smoking. Eat light and easy-to-digest food for dinner the night before.???? Those who cannot undergo gastroscopy: severe heart and lung diseases that cannot tolerate endoscopy; patients suspected of having shock or digestive tract perforation; patients with mental illness who cannot cooperate with endoscopy; patients with acute inflammation of the digestive tract, especially corrosive inflammation; obvious aortic aneurysm; stroke patients.???? Zhu 13 reminds you: gastroscopy and colonoscopy are not the same thing! Gastroscopy is actually not painful, except for a little nausea, it's not painful——next time I'll talk about colonoscopy, which will be a bit embarrassing because it's not inserted through the mouth, but from the anus——what, isn't that the legendary "explosive enema"? !!!!! Correct, it is——o(n_n)o Haha!???? Wishing every reader good health, no disease and no pain is actually the happiest thing!
