About 5 weeks ago I got really bad constipation, which led to massive anxiety on my part. My late father was a Diabetic who was insulin dependant, so I asked the Doctor at the time if I could have a blood fasting test. I had two blood tests which came back with the following numbers 50 and 51. I really don't understand what these numbers mean, whether they are high, low?, nobody has explained. I am seeing a Diabetic Nurse on the 10th. Many thanks for your help.
