Can I Schedule These Surgeries a Month Apart?

Hi Burnt Sugar
I have to agree with Dr Kraft.   More time between these procedures will make the surgeries safer for you. Brazilian Butt Lift and Tummy Tuck are both big surgeries. 
Having multiple procedures at the same time has a higher risk of complications.  Having multiple procedures within 4 weeks also adds additional risks.  Your body needs time to recover from the first surgery before you impact it with another even larger surgery.  Having any major surgery like these will drop your blood count as well as deplete your protein stores and healing factors as well as depress your immune system. 
I usually recommend a minimum of 6 weeks and even as much as 3 months between larger surgeries to be safe and let your body recover and be ready for the next surgery!  
Also...  combining a Tummy Tuck with the Brazilian Butt Lift is a very tough combination.  I have done this combination many times and all of my patients will tell you that recovery is hell. But they also all say they would do it again in a heartbeat just to get them both done.  But you need to be prepared for this!   

I usually recommend that my patients have the BBL first, especially if they don't have much fat to work with, then have the tummy tuck later. 
Good Luck

I am the contrarian here and I know that my anesthesia team agrees. Major procedures should be separated ideally by six weeks to allow you to recuperate from the anesthesia. This should not be a race to accomplish as much as possible but should take into consideration the length of the procedures and anesthesia, your recuperation from the first operation, etc. I never accept a deposit for operation #2 until the patient is satisfied with #1. Patients are sometimes surprised at how easily (or not so easily) they recuperate from surgery for a variety of reasons and this can't be anticipated. Don't pressure yourself and let your body heal. Best of luck!
