I was surprised to receive an invitation for the standard NHS health check as it is only a few years since I ended up with one when I went for a cervical smear screening a couple of years ago - which I neither needed nor wanted but 'went along with' and now regret.
The practice nurse took 'more than just at Christmas' as a confession of an unhealthy level of alcohol use (I have one drink a fortnight - a bottle of beer or a small glass of wine) I discovered later that she had entered 'patient refused to discuss weight reduction diet' in my records which is a flat out lie. She took no notice of my health condition and I also told her about some other symptoms I had had and she took no notice of those... which meant I delayed seeing the GP for another month with potential signs of cancer (fortunately not but it was an urgent referral to hospital) She was disturbingly incredulous that I had come through the menopause without HRT.
I'm now a healthy BMI, my alcohol use has not increased, I do as much exercise as I can given my health condition (and achieve close to government guidelines), my diet has not changed for the worse, I monitor my own BP at home and it is fine.
Which would leave blood sugar testing and cholesterol testing. There's no information in the leaflet which gives enough information for this to be done with informed consent (the results have consequences otherwise there's no point doing it) The letter says the appointment would be with a health care assistant. This is therefore not a health professional.
