First you should have compression after liposuction not drains. Second, leaving the wounds open makes an incredible mess an increases the risk of infection. Your body will absorb the extra fluid. In fact, the absorption of the fluid is part of the calculation of how much intravenous fluid you should receive. Third, if you can have surgery on Friday and be back to work Monday, you did not have enough fat removed. After liposuction surgery, I advise the patients to take one week off from work. You would need full time help with your children for that first week. At that point we take out the stitches and the patients may return to work, but may not engage in any strenuous activity. At one month, the patients start low impact cardio. At two months they can engage in more strenuous physical activity. The compression garment is worn for at least 6 weeks.
