Hormone Replacement Therapy (HRT) is used to relieve the nasty symptoms of menopause. Because it’s not always clear what causes the complaints doctors do not always prescribe the same medication. A few possibilities:
Only estrogens, prescribed when the doctor has the idea the estrogen level is too low. Vaginal dryness and hot flashes can be solved this way. But without progestagins (the synthetic modifications of the progesterone molecule) there may be side effects.
A combination of estrogen and progestagins. The progestagins meet the objections of estrogen only therapy. This combination may also help if the woman complaints of a lack of sexual desire.
Only progestagins, from the idea that complaints during menopause are caused by estrogen dominance (in comparison to the progesterone level)
Some advocate the use of natural hormones (having exactly the same structure as the hormones your body produces). They are claimed to have fewer side effects than synthetic hormones.

If you choose HRT to get rid of your complaints get well informed beforehand about the side effects and risks.
