Body not adjusted to hormone(estrogen) deficiency
Detailed Answer:
Hi thanks for using XXXXXXX
I went through the query and understood your concern.
I like to give you the explanation and some of the causes for hot flashes in elderly age.
1. During
menopause the production of estrogen and
progesterone is disrupted. This change in hormone levels causes the
hypothalamus of the brain that controls temperature and sends out signals to causes hot flash.
2. Some elderly person suffer from them for many more years even after menopause, when the body has adjusted for the change in hormones due
estrogen deficiency. Usually women who had surgically induced menopause are more likely to suffer with hot flashes for a longer time after menopause.
3. Some medications and conditions like
thyroid disease,
diabetes and panic disorders can cause hot flashes.
4. There may be some triggers for hot flashes like stress, alcohol,
smoking and warm environment.
So I advice you to try and keep stress levels to a minimum wear layered clothing, avoid using heat makers like hairdryers, eat healthy foods, and exercise regularly. Get examined by your doctor once to rule out other causes that mimics hot flashes and follow the above measures. If still you feel uncomfortable then you can try HRT after your doctor's advice.
