I am actually quite shocked at the direction this thread has taken. The OP was trying to open a discussion, but it's turned into a lot of people getting offended and basically saying 'well it was OK for me so it must be OK to be obese and choose to get pregnant'. At the risk of getting shot down, this strikes me as classic 'It won't happen to me' mentality - Risk is not an all-or-nothing thing. Increased risk means just that - it doesn't mean that the whole of science and the medical profession have got it wrong just because some people get lucky and escape any of the possible outcomes of that risk.
Personally I would never TRY to get pregnant without reducing any risk-factors that I may have... obesity is a significant risk-factor and can be addressed. Yes, medical issues may make this more of a challenge for some than others - but it can be addressed.
Just some food for thought from materials forming part of my degree course:
- French studies in 2007 put the increased costs of prenatal care in overweight and obese women at between 5 and 16 times higher than women of healthy weight, and
- The percentage of babies admitted to intensive care as 3 and a half times higher!
- Obese women who manage to conceive are 3 times more likely to suffer miscarriage or have a baby with spina bifida or other defect.
If it was simply about the risk to oneself, I would agree that it's fine to just let people do what they like, but it's not!
Something I've learned from MY degree courses (including courses in epidemiology nutrition, human sexuality & childbearing, and women's health):
----And the costs are increased because doctors insist on classifying women as higher risk simply because of their weight
----The babies are admitted to ICU because D's intervene in obese women's labor/pregnancy because they "assume" there are going to be problems when there aren't any.
----Saying "who manage to conceive" makes it sound like it's not likely, when, in fact, most obese women aren't infertile
----something being 3 times more likely doesn't mean it's likely in most circumstances.
Being obese have having a healthy pregnancy doesn't make a woman "lucky" as you put it - because most obese women have normal, healthy pregnancies.
There is risk in ALL pregnancies, and simply because someone is higher risk doesn't mean that it is unethical for them to become pregnant.
And as for what I've highlighted, this truly is a case of MY body is MY body and it's no one else's business.
