You can have an gastroscopy done at a specialist clinic, they will give you spray for the throat, and a bit of sedative. However, if you have sedative, you will need someone to accompnay you back home. If you need to have a coloonoscopy, then this can (but not always) be done in a public hospital as a day case. If you go to a private practitioner he/she will expect you to be admitted to a private hospital for at least one night. If you want to go private, you can a referral to a specialist at a hospital and they will do it as a private case. It laregely depends on your condition and age and other factors. For colonoscopy some preparation of the bowel is required and some blood tests. For a gastroscopy, the procedure can be done quickly with the back of themouth sprayed with lignocaine and a thin gastrocope is passed down into your stomach. it is a bit uncomfortable, but fast and the risk is low.
