Levothyroxine linked to high blood sugar readings.

I got up this morning and planned to check my blood sugar but was wondering why the readings lately have been running a little high and just thought i would look up if my levothyroxine might have anything to do with it. I am glad i found your site, i learned a lot from here. I am on a low dose, 25mg. When my doctor told me i had low t3, i didn't want to take any medication so i waited awhile before taking it but decided to give it a try, i didn't see much difference in how i felt except it seemed that my thinking was better and my vertigo got better, not a big weight gain for me either, i don't usually have a weight problem. I will bring this up when i next see my Dr. in March.

Do you have a copy of your latest blood results that you can share with us?

Its highyl likely that if you're only taking 25mcgs Levo then you need a dose raise. The link to Levothyroxine is that you're simply not taking enough.

25mcgs Levo is a starter dose for the elderly and those with heart issues.

The idea is to take a dose for 6-8 weeks then rerun blood tests and raise th dose. Repeat until TSH is at or just below 1 where most people feel well.

It's ideal if you can always get the same brand of levo at every prescription.

Always take Levo on an empty stomach an hour away from food or caffeine containing drinks & other meds. Many people find taking it at bedtime works well for them.

When hypo we get low stomach acid which means we cannot absorb vitamins well from our food, regardless of a great diet. For thyroid hormone to work well we need OPTIMAL levels of vitamins. Have you recently or could you ask your GP to test levels of ferritin, folate, B12 & D3?

The American Thyroid Association notes that hypothyroidism has been seen to produce a change in blood glucose levels, because is is a metabolic disease:
