How can I help avoid fluid retention and swelling?

I recommend you ask your surgeon about the supplements you want to take. The ingredients have to be checked to make sure that they won't interfere with your recovery. Swelling can take up to a year to subside. During this time, you should restrict sodium intake and sleep on your back as much as possible. Lymphatic massage can also help.

Although some supplements are safe, many are not FDA approved and often contain ingredients that should be avoided before and after surgery.  Many supplements can increase bruising and bleeding, increase heart rates and blood pressure, increase blood clotting, etc.  Also, some amount of swelling is necessary for proper healing to occur. I would recommend consulting with your surgeon prior to considering any supplement before, during or after surgery.

Swelling is a natural event in wound healing.  It is caused by lymphatics being disrupted and cannot be rushed.  Lymphatics may take a year to totally unite and function normal.   In the meanwhile there are things one can do to reduce swelling.  Sleep with head elevated.   Avoid Sodium  (salt) as much as possible.  Keep your sodium intake to less than 1500mg a day and you will have some better control of swelling.   But remember swelling is a normal part of wound healing.   My Best,  Dr C
