I have an underactive thyroid so I went for my routine blood tests this morning. Since last time the only thing I have consciously changed is doing C25K. I asked the practice nurse to take my blood pressure as well and my it has fallen from 134/90 to 120/80, which is really pleasing. Anyway, she had never heard of C25K and she told me that she works in two different GP surgeries. If any of the HealthUnlocked authorities are reading this I would be glad to take some info into the surgery for them, as it has not made it onto their radar.
