I'm 5 weeks post-op and still draining 50cc's in a 24hr period. Is this normal and should it be slowing down?

It is best to speak directly to your plastic surgeon to evaluate if anything needs to be done next. 

In my experience (using multiple plicating sutures to minimize the space under your tummy flap) most drains are removed by 1-2 weeks. Typically surgeons will remove drains once the drain output is less than 30cc/day x 2 days (but this varies among surgeons). Seems like you are close and as long is the trend is less each day hopefully you will be able to have them removed sooner. 

If the drainage continues your surgeon may elect to perform sclerosing therapy (injection of a material to try to cause local inflammation and decrease the seroma).

Thank you for the question! It is rather difficult to fully evaluate your situation without an in-person exam. It is not uncommon for tummy tuck patients to experience postoperative fluid collections under the skin known as seromas. Seromas often resolve on their own, but may require drains that will stay in for 1-2 weeks.  If you still experience persistent seromas and draining 5 weeks after surgery, I'd recommend alerting your plastic surgeon to your concerns. 

An in-person exam with a board-certified plastic surgeon would be the best way to assess your needs and guarantee a reliable medical advice. Best of luck!
