Mobilization of fluid

Often, during the first week after surgery, people retain a lot of extra water weight.  Typically, sometime in the second week, the body starts to mobilize the fluid, and so, there's a lot of urine flow!

That's the most likely possibility.  If you have fever, or pain when you pee, however, that could indicate a urinary tract infection.

All the best,

Frequent urination after liposuction

What you describe it it's not a typical.

Immediately after liposuction patients tend to swells.

Sometimes substantially.

This swellin causes patients to be dehydrated requiring consuming more  fluids.

The swelling later on reverses and the extra fluid that was held in the swollen tissue's returns to the circulatory system and excess water it's eliminated by the kidneys as urin.

Liposuction and urination

As the swelling goes down, you will urinate a lot as your body tries to remove the excess fluid that it retained after surgery.

Frequent urination after liposuction. causes

Congratulations on your procedure and thanks for sharing your question. I can appreciate your concern.

Frequent urination is common after liposuction due to the volume of fluid injected for removing the fat. Another possible reason is a urinary tract infection due to use of a foley catheter. 

Finally, make sure that your doctor is aware of your process. He should be able to guide you best in your care.

Wishing you the best in your journey


Yes. That is the normal response to the swelling being eliminated. If you had a bladder catheter during the surgery there would also be a very small chance of a urinary tract infection, especially if there is also burning and/or your urine is cloudy.

Urinary frequency after surgery

The standard of care in liposuction is to perform the tumescent technique.  That means that the fat is prepared for removal prior to evacuation.  It is prepared by injection of a solution of IV fluid to help liquify the fat and make aspiration more effective, lidocaine for comfort, and epinephrine to constrict blood vessels and minimize bleeding and bruising.  Liters of fluid may be injected.  Some of the fluid is aspirated with the fat.  Some may leak out through the incision.  Some remains as a component of swelling.  In addition to this retained volume, a long operative case requires ongoing IV hydration.  So most patients leave the OR even heavier than they began due to water weight!  As a patient recovers from surgery, this fluid is "mobilized" by the body and urinated out.  Rest assured this diuresis is a sign of progress and healing and will resolve over time.

Uninary frequency

After liposuction, there is a lot of swelling.  About a week post op, a lot of this fluid is mobilized and you urinate it away.  It is likely very normal to be urinating more than normal, at this point.

Mobilizing Edema After Liposuction

Yes, it is common to "mobilize your edema" after the first 3 days following surgery. This is especially true with liposuction as a lot of saline (salt water) is injected in order to minimize blood loss during the procedure. The Sodium in saline retains fluid, so you are now washing the sodium out of your body.
