What are the risks of having a general anaesthetic?

October 30, 2019

Straight after a general anaesthetic you may feel tired, dizzy or
weak. You must have someone to collect you and stay with you for the first 24 hours.

During the first 24 hours you must not:

  • Drive or operate any motorised vehicle or electrical equipment
  • Sign any legal documents or make important decisions
  • Drink alcohol

You may feel weak or dizzy at times during the first seven to ten days. If this happens, sit down until the feeling passes. You may also have the “post-operative blues”, though this should soon pass.


If you have not done so already we will ask you to sign a consent form. As with any treatment or procedure we must seek your consent beforehand. Staff will explain the risks, benefits and alternatives where relevant before they ask for your consent.

If you are unsure about any aspect of the procedure or treatment proposed, please do not hesitate to ask for more information.
