Even though the Fda (Food and drug administration) still approves oestrogen to prevent the bone-thinning disease known as brittle bones, doctors usually recommend medications known as bisphosphonates to deal with brittle bones.
Lengthy-term systemic hormone therapy to prevent postmenopausal conditions is not routinely suggested. However, many data claim that oestrogen can decrease the chance of cardiovascular disease when taken at the start of postmenopausal years.
A current, randomized, controlled medical trial — the Kronos Early Oestrogen Prevention Study (KEEPS) — explored oestrogen use and cardiovascular disease in more youthful postmenopausal women. The research found no significant association between hormone therapy and cardiovascular disease.
For ladies who haven’t had their uterus removed, oestrogen is usually prescribed together with progesterone or progestin (progesterone-like medication). It is because oestrogen alone, if not balanced by progesterone, can stimulate development of the liner from the uterus, growing the chance of uterine cancer. Women who’ve had their uterus removed (hysterectomy) don’t have to take progestin.
