Does gastroscope and colonoscopy hurt?

Colonoscopy: The preparation is a little uncomfortable, because I have to drink laxatives and have diarrhea until I have watery diarrhea. When taking pictures, the tube enters from the anus, and I feel a lot of gas in my stomach, so it doesn't hurt so much. When turning, the tube will hurt slightly. The whole journey takes 5~ 10 minutes, which is acceptable. You can talk when taking pictures. Clear mind.

Gastroscope: You don't need to do preparatory work, just do it as you like, and don't eat breakfast (usually in the morning). When taking a picture, the tube enters from my mouth, and I feel sick, want to vomit (like chopsticks digging my throat), and my saliva increases. I feel less pain, but I don't feel well. The whole journey takes 5~ 10 minutes, and I feel tolerable. You can't talk at the right time. Clear mind.

To sum up: gastroscope is uncomfortable, and both of them have painless choices, mostly around 300 yuan, but only local anesthesia. Personally, it is not recommended to do painless, and young people think it can be tolerated. The 3000 fast upstairs is a capsule endoscope, which has photographed the whole digestive system, stomach, large intestine and small intestine.
