Thanks all for the info.
This is my first blip so I dont yet have any trend data. I have been doing medicals in Australia and Asia since 1986 and had no problems before.
I see my Doctor here in the US on tuesday and I am hoping his response is "lets try diet and exercise until Dec 31 and then all should be fine". That way I get fitter and get christmas off.
These medical hiccups are very common in China and have a way of getting sorted eventually.
