welcome to HCM
This is Dr Amit. Hot flashes are mostly caused by the hormonal changes of menopause
. As the estrogen level falls it has a direct effect on the hypothalamus
the part of the brain responsible for controlling our appetite, sleep cycles, sex hormones, and body temperature.
So the drop in estrogen confuses the hypothalamus and causes hot flushes and other effects of menopause like anxiety, depression
and lack of interest in sex. It has nothing to do with thyroid hormones.
To prevent hot flushes, consider avoiding these triggers:
1.Stress,Caffeine,Alcohol,Spicy foods etc
2.Stay cool and do deep breathing.
3.Talk to your doctor about taking HORMONE REPLACEMENT THERAPY
(HRT). This treatment prevents hot flushes in many women. In addition, it can help other symptoms of menopause, including vaginal dryness
and mood disorders.
Hope i have given satisfactory answers to your questions.
