Hysterectomoy and menopause?

My mom is 56. She had a hysterectomy in her late 30s. Over the past year or so, it appears that she goes through mood swings (she's happy for 2 days, and then rather sad or lethergic for another 2 days). She complains of heart palipations, lack of sleep, and just general fatigue. Is it possible that she is being menopausal. Her behavior is causing negative impact on the family.

She was thrown into menopause when she had the hysterectomy. The symptoms of it are a withdrawal from the normal hormone levels. Well, unless she just recently got off her Hormone Replacement, there should be no drop in hormones. It is possible she is going through a mid life crisis, or maybe having some other health problem. She should see her doctor just to make sure.

FREEZING all the time? I have a thyroid condition, but can there be more to it?

I take Levoxyl, which may be needing a slight adjustment, but I get to the point where I can sit at my desk with a jacket on and a 1500 watt space heater turned to full blast and STILL be uncomfortably cold. Could this be related to thryoid, pre-menopause, both, or something else? I do take thyroid pills so it seems unlikely that a simple adjustment would do it.........I'm 43 and starting to experience "pre-menopausal" symptoms so I wonder if freezing is a symptom of that?

I have hypothyroidism and I am freezing all the time too...I would see your doctor to get a medication adjustment..it can do wonders!
