It will depend on the regulations of your airline and the nature of your surgery.
Check before you fly
Each airline has its own regulations about flying after surgery. Check with your airline before you fly, particularly if you've had complicated surgery.
If you've had any kind of major surgery, you should also check with your surgeon or GP before flying.
Types of surgery
As a rough guide, the Civil Aviation Authority (CAA) says that before flying, you should allow:
- one day after simple cataract or corneal laser surgery
- one day after a colonoscopy
- one to two days after keyhole surgery
- four to five days after simple abdominal surgery
- seven days after more complicated eye surgery
- 10 days after chest surgery or a coronary artery bypass graft
- 10 days after more complicated abdominal surgery
For other types of surgery, allow:
- one to two days after surgery where a plaster cast is applied – if you have a broken arm or leg, it will affect where you can sit; for example, you won't be allowed to sit in an emergency seat and you may have to purchase an extra seat if you cannot bend your knee to sit normally
- two to six weeks after surgery for retinal detachment that involves having a gas bubble put in your eye
Risk of DVT
If you're flying after recent surgery, especially on the hips or knees, you're at an increased risk of deep vein thrombosis (DVT), a blood clot in one of the deep veins in your body, usually in your legs.
Other factors may also increase your risk of DVT, including if you:
- have had DVT before
- have had blood clots already
- have a family history of blood clot
- are overweight or obese
- are pregnant
If you're at high risk of DVT, speak to your GP before flying. They may get advice from your surgeon, for example, or recommend that you delay your trip.
You can take steps to reduce your risk of DVT, such as drinking plenty of water and moving around on the plane.
The risk of developing a travel-related DVT is low, even if you are classed as moderate to high risk.
Travelling with a pacemaker
People who have had a pacemaker or an implantable cardiac defibrillator (ICD) fitted may travel without problems once they are medically stable.
Check your travel insurance policy carefully, as you may need to inform the insurance company that you've recently had surgery. This could increase the cost of your travel insurance.
