Why does my stomach look deformed? 3 weeks Post TT (Photo)

Although your concerns regarding your abdominal wall appearance are understandable, hopefully you are aware that it is much too early to evaluate the final aesthetic outcome of the procedure performed.  Time and patience will likely be your "best friends" in this regard.  You can expect improvements of the appearance of the  abdominal wall up to one year and beyond.Having said that, I would suggest that you seek follow-up with your plastic surgeon who will be the best position to evaluate the "lump" that you refer to.  Sometimes, a fluid accumulation (seroma)  may be responsible for this fulness. Best wishes for an outcome that you will be pleased with longer-term.

At 3 weeks swelling of the lower abdomen which makes it puff out beyond the pubic area is very common. Compression dressings and lymphatic massage may help. See your surgeon for a seroma check. Constructing garments or belts can make this worse so avoid them

As has been discussed here by other surgeons in a word......time. Patience is a virtue after surgery and you need to wait a full 3 months for everything to settle out. Use ice frequently and wear your binder. You are super early in your recovery and will see major improvements as time goes forward. There is no way to fast forward the recovery so just hang in there!
