Should I stop taking Spironolactone after my mommy makeover?

Thank you for your question.  I will assume that your surgeon knew of your spironolactone use prior to your tummy tuck, but now 12 days out, you should be fine to continue as any additional risks are negligible, and will only reduce any swelling.  Hope this helps.  

The primary issue with the use of diuretics in the perioperative period is the concern for dehydration and associated electrolyte abnormalities (alteration of salt balance).  Abdominoplasty requires an incision across the abdominal wall and elevation of the skin and soft tissue from the underlying muscle.  The dissection requires some blood vessels to be divided, compromising the blood supply to the tissue of the abdominal wall.  The fear with diuretic use is that dehydration could further compromise perfusion of this tissue, increasing the risk of skin loss, fat necrosis, or wound healing problems.  By 12 days, if you are healing well, the risk of continuing the spironolactone is probably minimal, as the blood supply is beginning to recover as you heal.  Thanks for the question, and best of luck with your recovery.
