At age 52 the doctor put me back on a low dose patch for hot flashes,after reading information on the side affects I decided not to do after about 1 year. Question the Doctor has insisted that I do the low dose patch again to help with hot flashes and he told me it could save my life by reducing the chances of a heart attack?? This is different than other information that I read about doing estrogen, I/m now sixty. Should I continue this low dose I have been doing 3 months hot flashes have stopped but i'm concerned about health.
