I had blood taken on 8 September checking HBa1c, thyroid function and kidneys etc. Everything was fine apart from thyroid, it went from 7.? to 22.? in space of 5 months. I am not surprised about a rise but surprised at such a large increase. So it is Levothyroxin at 100mg to start me off and to be rechecked in 3 months to find out if it needs to be increased to 125mg. I feel a bit teary today. I had to take Pumpkin to vet to check his diabetes and he doing fine, I asked about thyroid function for him and vet checking him out for it. I am ashamed to say I was in tears at the vet with him. Laura the vet said what applies to Pumpkin applies to me, we will both be fine if we are careful, I found out she was Type 3c, diagnosed after operation last November. I said "do you know about Diabetes.co.uk?" She will be looking into subscribing.
