My poor dad has been going back and forth to the doc's with various probs for the last few years but he keeps being told he is pre-diabetic as his fasting blood sugar tests at the hospital have been coming back at between 6 and 7.
Because of this he's gone on a low GI diet, etc, and has got a home glucose monitor to keep an eye on his blood sugar. However he always tests at around 4 if he does it himself and the follow up tests at the hospital have also been normal. He has no symptoms of diabetes but I know that prediabetes could be symptomless.

He is currently taking simvastatin, lisinorpil, ezetimibe and aspirin as he had heart attack 4 years ago. He is also on levothyroxine as he has an underactive thyroid. About a year ago my dad changed his statins as the one he was on caused a serious side effect. The doctor thought at the time that this side effect may have affected his test results. He also took he off beta blockers as his blood pressure is fine without it.

My question is could the drugs my dad takes affect the fasting blood test results as he has to take them during the fasting period. If not why would he get a normal reading in between the elevated readings.

I be very grateful for any advice as my dad's getting a bit worried.
Many thanks

  • I'm not familir with any diabetic testing that gives results in "single digits". All testing I'm familiar with, whether it's a "blood draw", or the "****k of a finger", etc., would result in a number somewhere from 80-120, if in the normal range. A result of 115-120 would be considered "pre-diabetic", although I think doctors use this to just warn people that they should watch thier diet a little. I worked on an acute medical ward for 20 years, and am diabetic myself, and really am stumped with the results you have given of 6,7 or 4. Are you sure this is correct? doc said i have a 103 and it was high. Im 33. Every man on my dads side had to inject themselves with insulin multiple times a day. I say had because there all dead. Im real scared of needles and i think i will eventually have diabetes. They were all real bad alcoholics that didnt stop drinking. I had a few health problems when i was 25 from drinking. I scaled it down dramadically. I went from a liter of vodka a day to nothing over time. I now drink beer 3 to 5 days a week. Between 6 to 12. (12 being on a weekend day with frends) what do you think... Oh and my doc pumps me with lisinipril25 hydromorophone20 2 times daily, Aamlodipine5, prilosec20,vitamin d 50000unt., and tramidol50.
