@Beowulfa, I agree, definitely, and it's true there are some terrible doctors out there. But I wouldn't like to make assumptions about what has happened here.
It may be that Hannah has a terrible gynaecologist, who either isn't taking the proper steps or is very bad at communicating with her.
But - and this isn't a comment on this particular case, more of a general observation - I do think it's well-established that patients can miss entire important chunks of discussion in certain circumstances - for example, when they are in a desperate situation, in constant severe pain, struggling to cope with the severity of their daily symptoms, probably functioning on very little sleep because of pain and worry at night - all this is a recipe for disaster when a difficult conversation about treatment options takes place and the patient is not firing on all cylinders, simply because their brain is behaving in an entirely normal way for a person in that difficult situation. I think it does happen that entire chunks of conversation simply don't lodge in their memory, or they can entirely reverse the sense of what was said, and believe they were told the exact opposite.
This is why I feel the BBC has a lot to answer for here. They haven't done any service to Hannah - they have put her in the public eye at a time when she is under huge pressure and correspondingly vulnerable. They haven't been fair to her doctors, who of course cannot answer the allegations without breaching confidentiality. They have potentially done harm to a lot of endometriosis sufferers, some of whom will believe that there is a cure for this, and that doctors are deliberately withholding the cure, even at cost of allowing women to continue in daily severe pain, doped up on opiates, in wheelchairs and catheterised - simply because of an ideological stance that treats us all as 'baby making machines'. I'm not saying treatment hasn't got a very long way to go, and there are a lot of problems with the system as is, but this sort of disinformation and distortion does us all harm.
OP, yes I agree there's a wide gulf between the current approach to hysterectomy in the treatment of endometriosis versus gender dysphoria. I'm guessing it's because the surgeons are relying on the accuracy of the experts in an entirely different field to assess whether the upsides of surgery outweigh the downsides. I have a feeling this may result in a lot of buck-passing later on. I've noticed similar in the approach to GnRH analogues (hormone blockers) in gynaecology - there was a time when they were the wonder drug, and it was thought that the benefits definitely outweighed the downsides. Now the negative effects are being regarded more seriously and I have a feeling prescribing has dropped, though I don't have stats to back this up - it's a feeling based on what I'm being offered as a patient and the fact that I'm no longer being encouraged to go down that route.
