My belly button has yellow and pink areas at 3 and a half weeks post op tummy tuck, is this normal? (Photo)

Thanks for the question. Providing photos is always helpful.
Judging by your description and the image you posted, it looks like you’ll need
to schedule a personal appointment with your board-certified plastic surgeon as
soon as possible. Your belly button does not look normal, but your doctor will
be able to help you out.

What I am seeing in your photos and what you are describing is not normal. Schedule an appointment to be assessed in person by your surgeon ASAP.My best,

Thank you for your question and providing photos. Based on the photos provided it appears your umbilicus is lacking blood flow and will not survive. I would discuss this with your PS. Best of luck

It appears that you have partial necrosis of your belly button.   This usually happens due to poor blood supply. This is very common in smokers, but can happen in anyone.   It sounds like you're making progress.   There does not appear to be any infection.   The best thing to do is continue following up with your surgeon.  I would recommend stopping the alcohol as alcohol not only kills bacteria, but it can also kill the cells that your body is making to try to heal the wound.  DiscoverTheBeauty.com 

 The appearance of your bellybutton is not normal. Some of the tissue did not survive.  I'm not familiar with this medication because it does not appear to be sold in the US. You need to follow up with the surgeon in person.

You are correct, in that your umbilical stalk has some necrosis and needs to be seen by your plastic surgeon.  The area will likely need some debridement and should likely heal with your surgeons care.

Hello and thank you for reaching out. From the photos you have provided, it appears that you need to make an appointment with your surgeon as soon as possible. I would also discontinue the use of alcohol to clean the umbilicus out. Best Wishes.
