Tell the anaesthetist about sleep
Sleep apnoea matters during surgical assessment, even if your main reason for treatment is weight loss. Bring any sleep-study report and explain whether you use continuous positive airway pressure, usually called CPAP. NHS bariatric information notes that sleep apnoea can affect how people respond to sedatives, pain medicines and anaesthesia. If you struggle to use your device, say so before travelling. The team needs an accurate account of your usual treatment, rather than assuming that owning a machine means it is being used comfortably and consistently. Ask whether further review is needed before the operation.
Make equipment arrangements explicit
Check whether the destination hospital expects you to bring your CPAP machine, mask and accessories. Ask what information it needs about the device and whether the ward can support its use. Plan power adaptors and transport with the equipment provider and airline as appropriate. Keep the device accessible during the journey rather than making assumptions about baggage handling. If you cannot use your own equipment at the hospital, obtain an agreed alternative before departure. The anaesthetic team should also explain how breathing and pain relief will be monitored after surgery. These arrangements belong in clinical planning, not just a packing checklist.
Review treatment after weight loss
Weight-loss surgery may improve sleep apnoea, but you should not stop prescribed breathing support because snoring seems better or weight has fallen. Ask the sleep service how reassessment will be arranged and who will decide whether treatment changes are appropriate. Give your home clinician the operation details and any relevant hospital observations. If fatigue, breathing symptoms or equipment problems continue after the trip, use the agreed clinical contact rather than waiting for a routine bariatric weigh-in. A plan linking the surgical and sleep teams helps you manage both conditions while progress is assessed. It also avoids leaving a later treatment decision entirely to you.
Questions to take with you
- Does my sleep apnoea need further review first?
- Can the hospital support my CPAP equipment?
- Who decides whether CPAP can change later?
