Just been catching up on the news and damn, that's really really shitty for her and her whole family. I can't imagine what's going through Lee's mind right now, such a mixture of emotions, bless him.
As a doctor I just want to give my two cents. I think based on such little information given in that post it's very difficult to speculate the extent of her condition. Like many have said it does appear that she was conscious after giving birth and then put into a coma the following day. It's not uncommon for pregnant women to deteriorate like this straight after giving birth as so much changes with your body/stress levels/hormones, but with the addition of COVID, obesity (and other underlying health conditions that we have no idea about), it's not surprising they have put her into a medically induced coma to help her rest and recuperate. People can be put into a coma for a few days just because it makes things easier for the team to manage and monitor the condition, it's not always because they're on death's door so to speak.
Personally, I also don't think it's terrible for people to be mentioning her weight, as it is something that people have consistently talked about in this forum so it shouldn't change just because she's unwell when there is a small possibility of it being related. I guess it's just about being tactful with it.
Anyways, God bless her and her family. I'm so glad to hear the baby is okay and I wish her well!
