At what week can I resume lifting heavy weights after tummy tuck with muscle repair without compromising the sutures?

Healing after a  #tummy tuck will require time. Some patients are out of bed and walking the night of surgery and every hour while awake. I allow my patients to return to work at one to two weeks with 14 days preferred.  However, no lifting or straining.  At three weeks, increased level of activity and full with no restrictions, at 6 weeks. 
As I advise my patients, if your work keeps you sedentary, you may return whenever you feel up to it. If your work is strenuous, wait until your work activity does not cause any superficial pain. Some employers will modify a person’s job duties so they can back sooner, but without physical activity. Our office can provide our patients with a note stating they are not to engage in strenuous activity for a specified period of time. The note will not disclose what procedure they have underwent. Therefore, you may have to request a similar note from your surgeon if you are not independently employed. I recommend avoiding heavy lifting and strenuous #activity for six weeks following your surgery. With that said, it may help you plan your return to work accordingly.
As for heavy lifting and other #strenuous #activities, it should be avoided for until you have clearance from your surgeon. You may, however, do normal activities at any time if they cause no pain or #discomfort. Let your body tell you what you can or cannot do. Aerobic exercise will raise your blood pressure, which could cause late bleeding and harm your result. Once you begin exercising again, start gently and let your body tell you what it can tolerate. Don’t rush!!  If you have concerns about your healing, or pain that you question to be unusual, it is important to call your plastic surgeon to discuss these further asked to be examined.

There are a variety of factors that go into answering that question. You should ask your surgeon what he likes to do. I personally tell my patients to wait at least 3 months before doing any exercise that involves strongly engaging the core. I hope this has helped.

You need to check with your surgeon about this. For my patients, I want them to wait 6 weeks before resuming any type of formal exercise, and then build up gradually as it feels comfortable. Good luck.
