I had a hysterectomy in February and had to push out my sleeve surgery. Both my Obgyn and weight loss surgeon said both procedures could not be done at the time. My sleeve surgeon said on top of the fact that both surgeries are pretty invasive, the major concern is the length of time you would need to be under. Each procedure ca be 2 to 3 hours or more. The longer you are under it greatly increases your risk of a blood clot and infections. My sleeve surgeon said 4 to 6 months between surgeries and my info was just submitted to insurance last week.
Good luck to you however you decide to proceed.
