Smelly Yellow Discharge 4 Weeks Post-Breast Reduction

         This type of yellow
drainage is most likely secondary to fat necrosis or infection. When breast
reduction is performed it’s not unusual to have areas of fat necrosis. Fat
necrosis results from damage to the blood supply of small areas of breast
tissue. Over the course of time, this fat dissolves and turns into a yellow
oily fluid which can leak through the wound closure.

 

         Infection can also
cause similar drainage, but this is usually accomplished by other signs of
infection. These include redness, fevers and chills.

 

         Although, this is
probably consistent with fat necrosis, the foul smell does suggest the
possibility of infection. For this reason, your progress should be monitored
closely. 

Yellow discharge may represent a number of potential source.  The most obvious is infection, especially when a foul smell is involved.  However, usually an infected region is surrounded bu redness and may or may not be accompanied by a fever.  Fat necrosis (devasularized fat) making it way out of an open wound is also possible.  This may also represent an early stitch abscess.  Your body sometimes reacts to foreign material in this manner.  It would be wise to keep in close contact with your plastic surgeon.  Express your concerns.  Post a pic for a more detailed evaluation.  I hope this helps

During a breast reduction,  breast tissue is removed and every effort is made so that the tissue which is left behind has a good blood supply and survives without a problem.   Alas, some of the tissue left behind can lose it's blood supply and dies.  This is called fat necrosis.  After the fat dies, it  can turn hard and then gradually breaks down to a "Wesson Oil" colored fluid which can leak out of the incisions.  If there is no infection, the fluid is just yellow and patience is required to wait while this resolves.  If the fluid is foul smelling there likely is bacteria in the fluid and you should be followed closely by your surgeon to monitor for infection.  Fat necrosis may take several months to fully resolve so be patient.

AT 4 weeks it is very unusual to have a true breast infection without additional symptoms such as fever. IT is probably more likely that you are experiencing breast fat necrosis. In many instances this will stop on its own and in other circumstances it may require surgical treatment. Antibiotics may be prescribed to prevent secondary infection
 

Thank you for the question.

Superficial wound healing problems and/or discharge are not uncommon after breast reduction surgery. These usually go on to heal without further treatment and without detracting from the long-term surgical results.

I would suggest continued follow-up with your plastic surgeon.

Best wishes.

New yellow drainage about a month after surgery may just be fat necrosis resolving itself.  If it's smelly, then try changing the dressing more often (3-4 times daily, rather than the typical 2 times daily).  Follow your surgeon's instructions and be sure you have close followup with her.

A foul smelling odor and discharge from your breast after a reduction need to be followed carefully.  Thismay represent an infection or fat necrosis.  Usually with fat necrosis this goes on to heal usually without many problems.
