Night sweats?

Does anyone get really bad night sweats occasionally and knows what causes it? I used to get them regularly with levothyroxine but fewer on NDT. Last night was awful, had to change nightdress as I was soaked. I ate late so failed to take my NDT till the early hours. I have had a total hysterectomy 3 years ago, on low dose hrt estrogen patches and cannot do without hrt as my hot flashes are awful when I stop.

Thank you

Low B12 can cause night sweats

Folic acid can help with menopausal hot flushes


Hi, see if you can catch the most recent episode of 'Doctor in the House' on iplayer. As Clutter has said, B12 was the culprit.

I'm religiously sucking on my jarrows B12, I also take metabolically b complex but guess my levels are not high enough yet. I've been supplementing since March. Last night more sweats. I'll keep on sucking!
