I have a chronic health condition not linked to my lifestyle. It requires appointments at my local surgery every 3 months for blood tests and blood pressure monitoring and also check ups and monitoring every 6 ,in this at the hospital. I take medication, via the nhs, for this condition daily, injections weekly and steroid injections for pain control as required, normally 2-3 times a year.)
I have developed very high blood pressure after having covid. The type isn't linked to my lifestyle or health. I will need medication, via the nhs, probably for life plus check ups every so often for monitoring.
In the past I have had infertility treatment, pregnancy treatment and monitoring, an emergency c section, treatment to correct Asherman's Syndrome, ablation surgery for SVT as well as a and e treatment for it in the past. I've has inpatient treatment for pneumonia in the last, and more recently inpatient treatment when I had covid. All of these things weren't caused by lifestyle, weight, etc. I did use the opticians for glasses but paid for laser surgery privately.
So I do use the NHS a lot.
Private treatment would be far too much for it all and unfortunately I'd struggle to get medical insurance at this stage, I'd have had to taken it out when much younger. My arthritis, for example, was diagnosed in mid to late 30s.
I do need to lose a bit of weight - and will aim to do so this year.
However, losing weight won't do anything to prevent my use of the NHS for the above.
