Meno clinics seem to depend on the consultant in charge and the budget of the area. Mine is good, luckily. The other one in my area not so good.
They weigh you, do urinalysis and try to stabilise you on an HRT. Might do blood tests too. They used to see me every 6 months, now it's a year unless I have problems, in which case I ring up. The waiting list for an appointment can be 3 months though.
You should have a nurse in charge. Hopefully someone nice that you can get on well with, as they are the ones that bounce you into urgent appointments if you need them.
