Is anyone familiar with excessive sweating as a symptom of Hashimoto’s? I developed Hashimoto’s a little more than seven years ago, and ever since then, even a slight uptick in temperature makes me break out in sweat. Now that it’s summer, I can’t walk down the street without getting totally drenched.

I’ve treated my hypothyroidism over time with Synthroid (137 MCG), T3 (100 MCG) and now Armour (4.5 grains). My T3 and T4 are both average to high (but normal for an otherwise healthy young man in his 20s). I stress that the sweating accompanied the onset of other symptoms of hypothyroidism and did NOT start when I began treating the hypothyroidism (I can be sure because a period of two years elapsed between those times).

If you aren’t aware of a Hashimoto’s- or hypothyroidism-sweating connection, what about a connection between something that can cause excessive sweating and that can also trigger Hashimoto’s? Or a connection between Hashimoto’s and other linked medical conditions for which sweating is a symptom?

Thank you all so much in advance for your help. I’m pretty much at my wit’s end, and it’s progressed way beyond the point of a mere inconvenience and into dangerous territory. I’m reluctant to walk my dog outside during the daylight because I might lose so much fluid from sweat that I’ll dehydrate.

I intentionally didn’t get my thyroid blood tests done this time, because I don’t give a damn what the results would say. No matter what, I’ll continue taking whatever medications, in whatever amounts, I find to treat my symptoms.

I desperately want, and have wanted for the past two years, this endocrinologist to address the fact that many of my hypothyroid symptoms have not gone away with treatment for hypothyroidism, whether using synthetic T4, synthetic T3, or natural T4+T3. The main three are weight gain, sleep disturbance and sweating. Right now I’m managing the sleep problem with melatonin, though I prefer not to; the weight gain isn’t such a big deal because I don’t really care about my weight; but the sweating, however, is really awful.

He seemed surprised that I hadn’t tried anything for the sweating yet. He gave me a prescription for Clonidine, which is a medication for high blood pressure that is also used to treat some other things. I am kind of worried to take it because I have already fainted a half dozen times and strongly prefer not to do so again. But I’m going to take it at night when I take my melatonin, so I’ll be in my bed or close to it anyway.

The doctor asked me to call him in two weeks and tell him how it’s going with the Clonidine. His receptionists do a terrible job and he never gets messages, so I guess I’ll have to go back over there to deliver the message in person.
