Helena You've had medical advice and I think you said you had loose skin? Forgive me if I'm confusing you with someone else. I am in awe of your weight loss. I know that maintaining it is the hard bit. I am far from perfect and trying really hard. If you have joint disease, it's more important to be a lower weight. So, BMI 29 is still far too much for me. I wish I wasn't! I'm aiming for BMI 25.5.
Hyancinth Sorry I genuinely into didn't see that post. There has to be a cut off somewhere and there will be people who have BMI of 30.0 who are told "no" while someone with a BMI of 29.9 will be told yes. Although my experience has been I have always been given stern and borderline patronising comments about my weight unless I've been in the normal BMI category.
Unethical was perhaps the wrong word. Although in cases of severe obesity of BMI 45+, the risks may outweigh the benefits. IMO, it is bizarre when there are limited resources, e.g. 18 month waiting list, to operate on someone who will wear out the joint much more quickly. If they can lose the weight, they are less likely to need a revision surgery (as quickly) which is more risky to the patient.
Ive never heard about the losing 10% and I'm sorry if I've not been clear but I am solely talking about orthopaedic surgery. Also, different areas do different things. I don't profess to know much about general anaesthesia or other risks for other surgeries, although I see there are others who have.
