If you feel unusually puffy or swollen after surgery, you may be wondering where all the extra fluid came from. Your hands may feel tight, your legs or feet may look swollen, or the number on the scale may be higher than it was before your procedure.
Some fluid retention can occur after surgery. Your body may temporarily hold onto extra fluid, and you may also receive intravenous (IV) fluids before, during, or after your procedure.
But not all swelling after surgery should be assumed to be simple fluid retention. Where the swelling occurs, whether it is getting better or worse, and what other symptoms you have all matter.
Surgery temporarily changes the way your body manages fluid.
Your body’s response to surgery can cause it to retain fluid for a period of time. You may also receive fluids through an IV during your procedure and recovery.
Together, these factors can leave you feeling puffier than usual after surgery.
You might notice:
The amount and location of swelling can vary considerably depending on your procedure and health.
If you were told to expect swelling after your particular surgery, follow the instructions your surgical team gave you for managing it.
Some swelling can be an expected part of postoperative recovery.
Swelling around the surgical area is common after many procedures, and more generalized fluid retention can also occur after surgery.
What is expected for you, however, depends on the operation you had.
Rather than deciding whether swelling is normal based only on how many days it has been since surgery, pay attention to where it is, whether it is changing, and whether you have other symptoms.
Your discharge instructions may tell you how much swelling to expect and when your team wants to hear from you.
If the swelling is new, rapidly increasing, much greater than you expected, or accompanied by other concerning symptoms, contact your surgical team.

They can contribute.
IV fluids are commonly used around surgery to provide fluids and medications and to support your care while you are unable to eat or drink normally.
After surgery, your body may temporarily have more fluid than it needs or may not eliminate that fluid as quickly as usual. This can contribute to postoperative puffiness or swelling.
That does not mean every case of swelling after surgery is caused by IV fluids.
Swelling can have many causes, including the normal response of tissues to surgery, reduced movement, medications, or medical problems that need evaluation.
If you are concerned about widespread swelling or feel that you are becoming increasingly swollen rather than improving, contact your care team rather than assuming the IV is responsible.
There is no single timeline that applies after every surgery.
Postoperative fluid retention may improve as your body recovers and regulates its fluid balance, but how quickly that happens depends on your procedure, health, medications, mobility, and other factors.
You may notice gradual changes rather than waking up one morning with all of the swelling gone.
If your swelling is not improving as your surgical team expected—or it is becoming more pronounced—let them know.
Avoid using a particular number of postoperative days as the point when swelling automatically becomes normal or abnormal.
Follow the recovery instructions you received for your procedure.
Depending on your situation, your care team may recommend appropriate movement, elevation, compression, medications, or other measures. Those recommendations are not interchangeable between patients.
A few important principles:

Your surgical team can help determine whether the swelling you are experiencing is expected and whether you need to do anything differently.
You cannot reliably diagnose the cause of swelling yourself.
This distinction matters because surgery and reduced mobility can increase the risk of a deep vein thrombosis (DVT), a blood clot that commonly occurs in a deep vein of the leg.
A DVT can cause:
Contact a healthcare professional promptly if you develop symptoms that could indicate a DVT.
Do not assume that new swelling in one leg is simply postoperative fluid retention, particularly if it is accompanied by pain, tenderness, warmth, or a change in skin color.
Your surgical team may have given you additional instructions based on your individual blood-clot risk. Follow those instructions.
A blood clot can sometimes travel to the lungs and cause a pulmonary embolism (PE), which can be life-threatening.
Seek immediate medical attention if you develop symptoms such as:
You can develop a pulmonary embolism without first noticing symptoms of a blood clot in your leg.
These symptoms should not be watched at home to see whether the swelling improves.
Contact your surgical team if your swelling is increasing, significantly different from what you were told to expect, or accompanied by other concerning changes.
You should also contact your team about increasing redness, pain, bleeding, drainage, or other concerning changes around your incision.
Your procedure-specific discharge instructions may identify additional symptoms they want you to report.
If you are unsure whether the amount or location of your swelling is expected, it is reasonable to ask. Your surgical team knows what type of swelling is typical after your particular procedure and can determine whether you need further evaluation.

Some fluid retention and swelling can occur after surgery. Your body may temporarily hold onto additional fluid, and IV fluids given around your procedure can contribute to feeling puffy.
But not all postoperative swelling should be attributed to fluid retention.
Pay attention to where the swelling occurs, whether it is improving or worsening, and what other symptoms accompany it. New swelling in one leg or arm with pain, warmth, tenderness, or redness needs prompt medical attention, while symptoms such as difficulty breathing, chest pain, or fainting require immediate care.
When in doubt, follow your procedure-specific discharge instructions and ask your surgical team whether the swelling you are experiencing is expected.
