HEALTH REPORT - Hormone 1 Replacement 2 Therapy Linked to Blood Clots 4
By Cynthia Kirk

This is Gwen Outen with the VOA Special English Health Report.


American researchers report more risks for older women who take the hormone replacement drugs estrogen and progestin. The researchers found that some women who take the hormones 5 are at sharply higher risk for developing blockages 6 in blood vessels 7 in the legs and lungs.


Hormone replacement drugs are designed to help ease problems among older women during menopause. This is when a woman's body produces less of the hormones estrogen and progesterone. Lower hormone levels in menopause cause some women to feel hot, experience mood changes, and suffer bone loss. To help with these problems, some women have been taking estrogen or estrogen with progestin.


Earlier studies had suggested an increased risk of blood clots among women who took the hormones. But researchers did not know until now that some groups of women are at even greater risk.


Researchers studied sixteen thousand women between the ages of fifty and seventy-nine years old. They found that the risk of blood clots for women who had taken the hormones was two times higher than for those who had not. The research showed that women over the age of seventy who took the hormones had more than seven times the risk. And the researchers found that being overweight also raises the danger of a blood clot 3 among women who took the hormones.


Normally, taking aspirin 8 reduces the risk of blood clots by thinning the blood. But researchers found that aspirin did not help the women who were also taking the hormones.


The latest findings come from a fifteen-year government study called the Women's Health Initiative.


For many years, health experts thought that the hormone drugs could help prevent heart disease, cancer and possibly mental illness in women. But many women stopped taking the drugs two years ago after a government study found that the hormones raised the risk of heart disease and some cancers.


Experts say taking estrogen and progestin does reduce the risk of the bone loss disease, osteoporosis. The drugs have also been shown to lower the risk for colon 9 cancer. However, American health officials advise women to take the smallest amount of hormones needed for the shortest possible time.
