After tummy tuck, your drain (if you had one) has only been out for a week or less, and tissue layers have only been healed/adhered to one another for a week, so activity must be conservative to avoid reaccumulation of fluid that could lead to a seroma, needle aspirations, drain reinsertion, or even more surgery to remove a pseudobursa (NONE of these is a good thing).
For the first two weeks after tummy tuck I recommend nothing that raises the blood pressure or pulse, but walking is good, and helps to avoid blood clots. Walking a mile right at 2 weeks may be stretching things a bit, but your heart rate and pulse (as well as your brow sweat) will be the real telling point as to whether or not this is too much at this point. A bit at a time is alright, but power walking or treadmill is not allowed yet. By the third week I allow more cardio, and exercise bike (gradually), treadmill, or more exertional walking is OK, but no vigorous exercise or health club yet. At the fourth week post-op I allow exercise, as long as it starts gradually and does NOT involve the abdominal muscles, so as not to disturb the muscle repair sutures. So no sit-ups, crunches, ab roller, etc. until 6 weeks after surgery. Then, all forms of exercise or activity are OK, as long as started gradually and endurance is built up naturally.
As exercise and activities are being ramped up, I allow my patients to switch from their surgical elastic/Velcro abdominal binder at about 3 weeks to a body shaper (Spanx or equivalent), and continue this for another several weeks. At 3-4 weeks is when we add complimentary massage therapy and ultrasonic treatments for our patients to help with swelling, firm areas, and scar softening. Patients also begin Vitamin E oil scar massage at home, and use silicone scar pads if needed.
After 6 weeks (and assuming no healing concerns). there are no restrictions except sun or ultraviolet avoidance for 6-12 months (or as long as the scars are pink), to avoid hyperpigmentation.
Of course, if you have a seroma, wound healing problem, or less-than-ideal scar, you will be asking your surgeon about this, so that is why you should ask and follow your own surgeon's advice regarding activity. Best wishes! Dr. Tholen
