Dear angiem2220,
If your umbilicus (belly button) is now almost closed, there is a strong possibility that the umbilicus has separated from the skin and will completely close over. The most common reasons for this happening is due to tension on the incision around the umbilicus, too much activity soon after surgery, or smokers who resume smoking after a tummy tuck (or never quit in the first place).
During a tummy tuck, an incision is made around the umbilicus so that it is detached from the tummy skin. The entire tummy skin shifts downwards (as the extra skin is removed), but the umbilicus stays in the same spot. A new opening in the skin overlying the umbilicus is made, so that it can be brought back out. Once brought through the new opening, it is sewn to the tummy skin. For one or more of the reasons listed above, the umbilicus (gradually) became separated from the tummy skin, and started the process of closing shut completely.
Bottom line: your situation is not an emergency, but you should see your plastic surgeon to have it corrected. Often this can be done with just local anesthetic anesthesia. Good luck.
