6 Months Post Op After Diastasis Recti Repair? (photo)

The hard line that you are feeling is most likely the suture line from the repair of the diastasis or separation of your six pack abdominal muscles.  Your scars appear to be healing well.  I would make sure keep sunscreen on them and keep them covered for another 6 months to get the optimal result.

Hello. The sensation you feel down the middle of your stomach is most likely the plication suture used to repair your diastasis recti. Your scar is still dark but should continue to lighten for about another six months. If the scar is still dark after a full year post op either a tummy tuck or scar revision might be considered.

The firm area that you are feeling in the midline from your ribs to the pubic area is from the imbrication and plicaton of your fascia from the operation.  This will soften up over time.  Your scar seems a bit red and you may want to try using a product with silicone or silicone gel sheeting.
