Question: Hypothyroidism and high glucose?


 mau - Thu May 03, 2007 10:15 pm

Hi -
I'm a 38yo female, (5'6" 140lbs). Got blood test recently due to fatigue, short-term memory problems, mental fuzziness and family history of hypothyroidism. TSH was 5.7 and doc prescribed synthroid. Have only been on it for a few days but am sure it will help when it kicks in.

However, fasting glucose has been on high end last 2 tests (101 in Jan, 95 in April). My father is diabetic. I have not gained weight but LOST weight. And I don't eat alot of sugar or bad carbs. I recently read a journal article linking thyroiditis to high glucose and another to insulin resistance. However, I'm not a biochemist and really have no idea what they are talking about. I would like to get to the ROOT of the problem though and not just treat the symptom of a different problem.

Should I investigate this further? I want to go to another doctor that is more knowledgeable about this than my GP. What type of doctor could help?

User avatar Fasting glucose levels are generally considered normal if they are between 60 and 100. Levels of 100-126 are considered impaired and levels above 126 are considered consistent with Diabetes.

Your levels are really borderline normal. I would not be concerned about this. As your thyroid becomes normal you may see improved glucose utilization as well.

I would suggest you have the test repeated in 6 months or so once your thyroid is normal.

Best wishes.

Thanks Dr. Lowe. That makes sense and puts my mind at ease too!
