Possible Kidney Problems and Other Risks After Tummy Tuck?

Hic,
Thanks for the question. To my knowledge, there is nothing in the literature that would suggest a correlation between a tummy tuck or abdominoplasty, and the development of delayed-onset acute renal failure (ARF) or chronic renal failure for that matter. Most patients, in fact, do quite well following a tummy tuck and tend to be some of our most pleased clients.
If you are a serious body builder and are taking any sort of performance-enhancing supplements, I would recommend a thorough pre-operative work-up including some general labs prior to undergoing a tummy tuck to ensure that your underlying renal status isn't in a compromised state.
Best of luck.

I am not aware of any relationship between abdominoplasty and a delayed renal failure.
Occasionally there can be some prolonged numbness in the lower abdomen.
There are trade-offs involved with any surgical procedure. Scar, numbness, cost etc.
The majority of patients who have a history of significant weight loss as you describe end up very pleased after abdominoplasty.
