PATIENT INFORMATION

Obesity

Body weight can affect airway management, breathing, sleep apnoea, blood-clot risk, positioning, drug dosing and postoperative care.

The purpose of asking about weight is to plan safely, not to judge you.

Why it matters

  • Breathing: lung capacity can be reduced when lying flat, and oxygen levels can fall more quickly.
  • Airway: managing the airway may need extra preparation.
  • Equipment: the team may arrange suitable beds, tables, blood-pressure cuffs and positioning aids.
  • Medicines: some drug doses are calculated differently.
  • Blood clots: the risk of clots in the legs or lungs may be higher, so prevention measures may be used.

What to tell the team

  • Your current weight, if you know it
  • Snoring, sleep apnoea or CPAP use
  • Reflux or heartburn
  • Diabetes, high blood pressure or heart problems
  • Any previous problems with anaesthesia

Weight-management medicines

If you use GLP-1 or other weight-management medicines, mention them specifically because they may affect perioperative planning.

After surgery

Getting up and moving early, deep-breathing exercises and following blood-clot prevention advice all help recovery. Ask the team what is planned for you.
