My fasting blood sugar count is 174 mg/dl [9.7 mmol/L], and, within two hours after eating, it is 134 mg/dl [7.4 mmol/L]. This seems to be contrary to the normal readings. Is this in order? The laboratory staff say that this reading is in order, and this can happen. Is there any precedence? Are there any precautions to be taken?

You have asked a good question. It is a common problem for people with type 2 diabetes to wake up with a high blood sugar and see it come down after they wake up and eat their first meal. You did not say if you are taking any medicine, but there are several medications available for the treatment of type 2 diabetes. You have asked about taking precautions. A fasting blood sugar of 174 mg/dl [9.7 mmol/L]is certainly higher than the target range of less than 120 mg/dl [6.7 mmol/L]. I would suggest you discuss available therapies with your doctor to help you bring this number down to a safer range.

Additional comments from Stephanie Schwartz, diabetes nurse specialist:

You have not told us whether you have type 1 or type 2, nor have you told us whether nor not you take insulin. If you are on insulin, it may be that your insulin doses need to be adjusted. Without more information, it is hard to answer your question, and as Kris has suggested, you need to discuss this with your doctor.
