New Research on HRT indicates that there is an increased risk of getting a blood clot in postmenopausal women
Women who are overweight or have a genetic pre-disposition to blood clots should avoid HRT pills, but skin patches seem to be safer, says a systematic review and meta-analysis by French Scientists.
This was perhaps due to the different way oestrogen is absorbed into the blood stream, they suggested.
But as the authors themselves say, this needs to be confirmed with more research
However, the authors warned that the results should be treated with caution as the data is from observational studies and need to be confirmed with more research.
No trials have yet investigated the effects of oestrogen patches on the risk of blood clots.
