Has anyone experienced night leg cramps & fatigue while on Synthroid?

ChitChatNine

Been on Synthroid for 6 yrs and am almost certain it's the med causing night leg cramps. I trialed off it for 3 days and the cramps went away. My doctor is considering a switch to something else, but this is so odd ---- I've been on Synthroid since '07 and have never had any issues. (sigh).

Can low carb intake interfere with Synthroid absorption?

Lately I reduced the carb and noticed an increase in my TSH labs from 2 to 10. Just wondering if low carb diet could be the problem.

Forgot to mention that fatigue is also a symptom being hypo. Just getting TSH won't tell the whole story; try to get FT3 and FT4, as well, since those are the actual thyroid hormones.

Things in your body can change over time, requiring adjustments in med dosage.

I get the cramps when I am a) hypo, even if labs are "in range", b) low in potassium or c) dehydrated/not drinking enough liquid.

Recommend that you get FT levels tested to make sure they are adequate and check potassium levels.
