Was too much fat removed during recent mommy makeover procedure? Original weight: 155lbs. I am 5'6" and 42 years old.

Thank You for you're question.The amount of fat that they removed on average is what could be removed from someone with a medium size frame. 7.5 pounds of fat is not an excessive amount of fat removed while keeping you're bodies proportions prior to surgery in mind. If you have any more questions, I recommend you  consult with a board certified plastic surgeon. 

Congratulations on having undergone the mommy makeover surgery.  Online consultants will not be of much specific help to you: there is no "normal" or statistically "average" amount of tissue/weight removed during these types of operations.   Obviously, much depends on the specific patient's anatomy, the exact operation agreed upon, exactly how the operation is executed... Best to address specific concerns/questions directly with your plastic surgeon. Best wishes for an outcome that you will be pleased with long-term.

High volume fat removal (over approximately 10 pounds) may lead to a higher risk of complications.  You will want to discuss your concerns with your surgeon and be aware of "red flag" symptoms to report.  The overnight stay at the hospital was a wise precaution.
