Most women are awake as hysteroscopy procedures are usually carried out without an anaesthetic or a local anaesthetic may be used to numb the cervix. However a general anaesthetic may be used if your hysteroscopy is likely to take a long time or if you are having treatment at the same time, such as fibroid or polyp removal.
A general anaesthetic puts you to sleep for the duration of the procedure. You will be unaware of your hysteroscopy and unable to feel any discomfort.
